Includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Entity may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Compensating balance arrangements that do not legally restrict the withdrawal or usage of cash amounts may be reported as Cash and Cash Equivalents, while legally restricted deposits held as compensating balances against borrowing arrangements, contracts entered into with others, or company statements of intention with regard to particular deposits should not be reported as cash and cash equivalents.

Includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Entity may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Compensating balance arrangements that do not legally restrict the withdrawal or usage of cash amounts may be reported as Cash and Cash Equivalents, while legally restricted deposits held as compensating balances against borrowing arrangements, contracts entered into with others, or company statements of intention with regard to particular deposits should not be reported as cash and cash equivalents.

| Description of Business, Basis of Presentation and Accounting Policies [Abstract] | |
| Description of Business Basis of Presentation and Accounting Policies | 1. Description of Business, Basis of Presentation and Accounting Policies American Tower Corporation is, through its various subsidiaries (collectively, “ATC” or the “Company”), an independent owner, operator and developer of wireless and broadcast communications sites in the United States, Brazil, Chile, Colombia, Ghana, India, Mexico, Peru and South Africa. The Company's primary business is the leasing of antenna space on multi-tenant communications sites to wireless service providers and radio and television broadcast companies. The Company also manages rooftop and tower sites for property owners, operates in-building and outdoor distributed antenna system (“DAS”) networks and provides network development services that primarily support its rental and management operations and the addition of new tenants and equipment on its sites. ATC is a holding company that conducts its operations through its directly and indirectly owned subsidiaries and its joint venture. ATC's principal domestic operating subsidiaries are American Towers LLC (“ATI”) and SpectraSite Communications, LLC (“SpectraSite”). ATC conducts its international operations through its subsidiary, American Tower International, Inc., which in turn conducts operations through its various international operating subsidiaries. The Company's international operations consist primarily of its operations in Brazil, Chile, Colombia, Ghana, India, Mexico, Peru and South Africa. The accompanying condensed consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The financial information included herein is unaudited; however, the Company believes that all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation of the Company's financial position and results of operations for such periods have been included. Results of interim periods may not be indicative of results for the full year. Subsequent events have been evaluated up to the date of issuance of these financial statements. These condensed consolidated financial statements and related notes should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2010.
Principles of Consolidation and Basis of Presentation—The accompanying condensed consolidated financial statements include the accounts of the Company and those subsidiaries and joint ventures in which it has a controlling interest. Investments in entities that the Company does not control are accounted for using the equity or cost method, depending upon the Company's ability to exercise significant influence over operating and financial policies. Significant Accounting Policies and Use of Estimates—The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results may differ from those estimates, and such differences could be material to the accompanying condensed consolidated financial statements. The Company considers events or transactions that occur after the balance sheet date but before the financial statements are issued as additional evidence for certain estimates or to identify matters that require additional disclosure.
Changes in Presentation—Changes have been made to the presentation of gross purchases and sales of short-term investments within the condensed consolidated statements of cash flows for the six months ended June 30, 2010.
Concentrations of Credit Risk—The Company is subject to concentrations of credit risk related to its cash and cash equivalents, notes receivable, trade receivables and deferred rent asset. The Company mitigates its risk with respect to cash and cash equivalents by maintaining its deposits and contracts at high quality financial institutions and monitoring the credit ratings of those institutions.
The Company derives the largest portion of its revenues, corresponding trade receivables and the related deferred rent asset from a small number of customers in the telecommunications industry. Approximately 54% of its revenues are derived from four customers. In addition, the Company has concentrations of credit risk in certain geographic areas.
The Company mitigates its concentrations of credit risk with respect to notes and trade receivables and the related deferred rent asset by actively monitoring the credit worthiness of its borrowers and customers. In recognizing customer revenue, the Company must assess the collectability of both the amounts billed and the amounts recognized on a straight-line basis. This assessment takes customer credit risk and business and industry conditions into consideration to ultimately determine the collectability of the amounts billed. To the extent the amounts, based on management's estimates, may not be collectable when billed, recognition is deferred until such point as the uncertainty is resolved. Any amounts which were previously recognized as revenue and subsequently determined to be uncollectible are charged to bad debt expense.
The Company's largest international customer is Iusacell, which is the brand name under which a group of companies controlled by Grupo Iusacell, S.A. de C.V. (“Grupo Iusacell”) operates. Iusacell represented approximately 4% of the Company's total revenue for six months ended June 30, 2011. Grupo Iusacell has been engaged in a refinancing of a majority of its U.S. Dollar denominated debt, and in connection with this, two of the legal entities of the group, including Grupo Iusacell, voluntarily filed for a pre-packaged Concurso Mercantil (a process substantially equivalent to Chapter 11 of U.S. Bankruptcy Law) with the backing of a majority of their financial creditors in December 2010 and subsequently concluded the process in April 2011 after a Mexican court ruled in favor of the refinancing plan presented by the two legal entities. As of June 30, 2011, Iusacell notes receivable, net, and related assets (which include financing lease commitments and a deferred rent asset that are primarily long-term in nature) were $20.9 million and $61.0 million, respectively.
Recently Adopted Accounting Standards— In October 2009, the Financial Accounting Standards Board (“FASB”) issued new guidance which establishes accounting and reporting guidance for arrangements including multiple revenue-generating activities. This guidance requires companies to allocate the overall consideration to each deliverable under the arrangement using the estimated selling prices in the absence of vendor specific objective evidence or third-party evidence of selling price for deliverables. This guidance was effective for any contracts entered into, or materially modified by the Company as of January 1, 2011 and did not have a material impact on the Company's condensed consolidated results of operations or financial position.
Accounting Standards Updates—In June 2011, the FASB issued amendments to disclosure requirements for presentation of comprehensive income. This guidance, effective retrospectively for the interim and annual periods beginning on or after December 15, 2011 (early adoption is permitted), requires presentation of total comprehensive income, the components of net income and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The implementation of this amended accounting guidance is not expected to have a material impact on the Company's condensed consolidated results of operations or financial position. |

This item represents the entire disclosure related to Investments in Certain Debt and Equity Securities (and certain other trading assets) which include all debt and equity securities (other than those equity securities accounted for under the equity or cost methods of accounting) with readily determinable fair values. Other trading assets include assets that are carried on the balance sheet at fair value and held for trading purposes. A debt security represents a creditor relationship with an enterprise that is in the form of a security. Debt securities include, among other items, US Treasury securities, US government securities, municipal securities, corporate bonds, convertible debt, commercial paper, and all securitized debt instruments. An equity security represents an ownership interest in an enterprise or the right to acquire or dispose of an ownership interest in an enterprise at fixed or determinable prices. Equity securities include, among other things, common stock, certain preferred stock, warrant rights, call options, and put options, but do not include convertible debt. An entity may opt to provide the reader with additional narrative text to better understand the nature of investments in debt and equity securities (and other trading assets).

| Financing Transactions [Abstract] | |
| Financing Transactions | 4. Financing Transactions
Revolving Credit Facility and Term Loan—As of June 30, 2011, the Company had $275.0 million outstanding under its $1.25 billion senior unsecured revolving credit facility (“Revolving Credit Facility”) and had approximately $3.0 million of undrawn letters of credit outstanding. In March 2008, the Company increased its borrowing capacity under the Revolving Credit Facility by adding $325.0 million of term loan commitments (“Term Loan”). As of June 30, 2011, the Term Loan was fully drawn. The Company continues to maintain the ability to draw down and repay amounts under the Revolving Credit Facility in the ordinary course. In July 2011, the Company borrowed an additional $100.0 million under the Revolving Credit Facility. The Revolving Credit Facility has a term of five years, and along with the Term Loan, matures on June 8, 2012.
Supplemental Credit Facility—On April 8, 2011, the Company entered into a new unsecured revolving credit facility (the “Supplemental Credit Facility”) that allowed the Company to borrow $860.0 million and on June 16, 2011 the Company received additional commitments for an aggregate of $140.0 million. As a result, as of June 30, 2011, the Supplemental Credit Facility allows the Company to borrow up to $1.0 billion.
The Supplemental Credit Facility has a term of five years and matures on April 8, 2016. Any outstanding principal and accrued but unpaid interest will be due and payable in full at maturity. The Supplemental Credit Facility does not require amortization of principal and may be paid prior to maturity in whole or in part at the Company's option without penalty or premium.
The Company has the option of choosing either a defined base rate or the London Interbank Offered Rate (“LIBOR”) as the applicable base rate for borrowings under the Supplemental Credit Facility. The interest rate ranges between 1.350% to 2.600% above the LIBOR rate for LIBOR based borrowings or between 0.350% to 1.600% above the defined base rate for base rate borrowings, in each case based upon the Company's debt ratings. A quarterly commitment fee on the undrawn portion of the Supplemental Credit Facility is required, ranging from 0.250% to 0.550% per annum, based upon the Company's debt ratings. The current margin over LIBOR that the Company would incur on borrowings is 1.850% and the current commitment fee on the undrawn portion of the Supplemental Credit Facility is 0.350%.
The loan agreement contains certain reporting, information, financial ratios and operating covenants and other restrictions (including limitations on additional debt, guaranties, sales of assets and liens) with which the Company must comply. Any failure to comply with the financial and operating covenants of the loan agreement would not only prevent the Company from being able to borrow additional funds, but would constitute a default, which could result in, among other things, the amounts outstanding, including all accrued interest and unpaid fees, becoming immediately due and payable.
As of June 30, 2011, the Company had not drawn on the Supplemental Credit Facility.
Colombian Short-Term Credit Facility—In connection with the purchase of the exclusive rights for towers from Telefónica S.A.'s Colombian subsidiary, Colombia Telecomunicaciones S.A. E.S.P. (“Coltel”), the Company entered into a 72.8 billion Colombian Peso-denominated revolving credit facility on September 3, 2010. On November 24, 2010, the Company increased the revolving credit facility by 66.3 billion Colombian Pesos. As of June 30, 2011, 139.1 billion Colombian Pesos (approximately $78.5 million) were outstanding under this facility. The maturity date of the credit facility was extended to July 25, 2011 from May 26, 2011. On July 25, 2011, the Company refinanced this credit facility with a new 141.1 billion Colombian Peso-denominated short-term credit facility (approximately $80.2 million). The maturity date of this new facility is October 25, 2011.
South African Bridge Loan—In connection with the acquisition of 959 communications sites from Cell C (Pty) Limited (“Cell C”), the Company entered into a 695.4 million South African Rand-denominated bridge loan (“Bridge Loan”) on March 2, 2011. As of June 30, 2011, 695.4 million South African Rand (approximately $102.7 million) were outstanding under this loan. The Bridge Loan matures on September 30, 2011.
Ghana Loan— In connection with the establishment of the Company's joint venture with MTN Group Limited (“MTN Group”) and the acquisition of 400 communications sites in Ghana. Ghana Tower Interco B.V., a 51% owned subsidiary of the Company, executed a U.S. Dollar-denominated shareholder loan agreement (“Ghana Loan”), as the borrower, with a wholly owned subsidiary of the Company (“ATC Subsidiary”) and Mobile Telephone Networks (Netherlands) B.V., a wholly owned subsidiary of MTN Group (“MTN Subsidiary”), as the lenders. The portion of the Ghana Loan made by the ATC Subsidiary is eliminated in consolidation and the portion of the loan made by MTN Subsidiary is reported as outstanding debt of the Company.
The loan accrues interest at 9.0% and matures on May 4, 2016. As of June 30, 2011, $30.2 million was payable to the MTN Subsidiary. Stock Repurchase Programs—During the six months ended June 30, 2011, the Company continued to repurchase shares of its Class A common stock (“Common Stock”) pursuant to its publicly announced stock repurchase program, as described below. In February 2008, the Company's Board of Directors approved a stock repurchase program for the repurchase of up to $1.5 billion of its Common Stock (“2008 Buyback”). During the six months ended June 30, 2011, the Company repurchased 4.4 million shares of its Common Stock for an aggregate of $224.7 million, including commissions and fees, pursuant to the 2008 Buyback. Between July 1, 2011 and July 22, 2011, the Company repurchased an additional 0.3 million shares of its Common Stock for an aggregate of $18.0 million, including commissions and fees. As of July 22, 2011, the Company had repurchased a total of 34.5 million shares of its Common Stock for an aggregate of $1.4 billion, including commissions and fees, pursuant to the 2008 Buyback. In March 2011, the Company's Board of Directors approved a new stock repurchase program, pursuant to which the Company is authorized to purchase up to an additional $1.5 billion of Common Stock. As of July 22, 2011, the Company had not made any repurchases under this program. Under each program, the Company is authorized to purchase shares from time to time through open market purchases or privately negotiated transactions at prevailing prices in accordance with securities laws and other legal requirements, and subject to market conditions and other factors. To facilitate repurchases, the Company plans to make purchases pursuant to trading plans under Rule 10b5-1 of the Securities Exchange Act of 1934, as amended, which allows the Company to repurchase shares during periods when it otherwise might be prevented from doing so under insider trading laws or because of self-imposed trading blackout periods. In the near term, the Company expects to fund any further repurchases of its Common Stock through a combination of cash on hand, cash generated by operations and borrowings under its credit facilities. Purchases under each program are subject to the Company having available cash to fund repurchases. |

| Derivative Financial Instruments | 5. Derivative Financial Instruments The Company is exposed to certain risks related to its ongoing business operations. The primary risk managed through the use of derivative instruments was interest rate risk. From time to time, the Company enters into interest rate protection agreements to manage exposure on the variable rate debt under its credit facilities and to manage variability in cash flows relating to forecasted interest payments. Under these agreements, the Company is exposed to credit risk to the extent that a counterparty fails to meet the terms of a contract. The Company's credit risk exposure is limited to the current value of the contract at the time the counterparty fails to perform.
If a derivative is designated as a cash flow hedge, the effective portions of changes in the fair value of the derivative are recorded in accumulated other comprehensive income (loss) and are recognized in the results of operations when the hedged item affects earnings. Ineffective portions of changes in the fair value of cash flow hedges are recognized immediately in the results of operations. For derivative instruments not designated as hedging instruments, changes in fair value are recognized in the results of operations in the period in which the change occurs. All of the Company's interest rate swap agreements expired in March 2011. As of December 31, 2010, the carrying amounts of the Company's derivative financial instruments, along with the estimated fair values of the related liabilities were as follows (in thousands):
During the six months ended June 30, 2011 and 2010, the interest rate swap agreements held by the Company had the following impact on other comprehensive income (“OCI”) included in the condensed consolidated balance sheet and in the condensed consolidated statement of operations (in thousands):

| Fair Value Measurements | 6. Fair Value Measurements The Company determines the fair market values of its financial instruments based on the fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Below are the three levels of inputs that may be used to measure fair value:
Cash and cash equivalents include short-term investments, including money market funds, with original maturities of three months or less whose fair value equaled cost at June 30, 2011 and December 31, 2010. As of June 30, 2011, there were no interest rate swap agreements outstanding. As of December 31, 2010, the fair value of the Company's interest rate swap agreements recorded as liabilities is included in other long-term liabilities in the accompanying condensed consolidated balance sheet. Fair valuations of the Company's interest rate swap agreements reflect the value of the instrument including the values associated with counterparty risk and the Company's own credit standing. The Company includes in the valuation of the derivative instrument the value of the net credit differential between the counterparties to the derivative contract. Items Measured at Fair Value on a Nonrecurring Basis—During the six months ended June 30, 2011, long-lived assets held and used with a carrying value of $3.8 billion were written down to their net realizable value, resulting in an asset impairment charge of $0.4 million. These adjustments were determined by comparing the estimated proceeds from sale of assets or the projected future discounted cash flows to be provided from the long-lived assets (calculated using level 3 inputs) to the asset's carrying value. Fair Value of Financial Instruments—The carrying value of the Company's financial instruments, with the exception of long-term obligations, including current portion, reasonably approximate the related fair values as of June 30, 2011 and December 31, 2010. The Company's estimates of fair value of its long-term obligations, including current portion, are based primarily upon reported market values. As of June 30, 2011, the carrying value and fair value of long-term obligations, including current portion, were $5.7 billion and $5.9 billion, respectively. As of December 31, 2010, the carrying value and fair value of long-term obligations, including current portion, were $5.6 billion and $5.8 billion, respectively.

| Income Taxes | 7. Income Taxes
The Company provides for income taxes at the end of each interim period based on the estimated effective tax rate for the full fiscal year. Cumulative adjustments to the Company's estimate are recorded in the interim period in which a change in the estimated annual effective rate is determined.
As of June 30, 2011 and December 31, 2010, the total amount of unrecognized tax benefits that would impact the effective tax rate, if recognized, was approximately $50.0 million and $33.0 million, respectively. The increase in the amount of unrecognized tax benefits during the six months ended June 30, 2011 is primarily attributable to uncertain tax positions assumed in connection with the Company's acquisition in Brazil on March 1, 2011. The Company expects the unrecognized tax benefits to change over the next 12 months if certain tax matters ultimately settle with the applicable taxing jurisdiction during this timeframe, as described in note 11 to the Company's consolidated financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2010. The impact of the amount of such changes to previously recorded uncertain tax positions could range from zero to $4.0 million.
The Company recorded penalties and tax-related interest expense during the three and six months ended June 30, 2011 of $1.5 million and $2.4 million, respectively, and during the three and six months ended June 30, 2010 of $0.7 million and $1.4 million, respectively. As of June 30, 2011 and December 31, 2010, the total amount of accrued income tax-related interest and penalties included in other long-term liabilities in the condensed consolidated balance sheets was $28.4 million and $18.0 million, respectively. |

| Earnings Per Common Share | 9. Earnings per Common Share Basic income from continuing operations per common share represents income from continuing operations attributable to American Tower Corporation divided by the weighted average number of common shares outstanding during the period. Diluted income from continuing operations per common share represents income from continuing operations attributable to American Tower Corporation divided by the weighted average number of common shares outstanding during the period and any dilutive common share equivalents, including shares issuable upon exercise of stock options, share based awards and warrants as determined under the treasury stock method and upon conversion of the Company's convertible notes, as determined under the if-converted method. Dilutive common share equivalents also include the dilutive impact of the ALLTEL transaction (see note 10).
The following table sets forth basic and diluted income from continuing operations per common share computational data for the three and six months ended June 30, 2011 and 2010 (in thousands, except per share data):
For the three and six months ended June 30, 2011, the weighted average number of common shares outstanding excluded shares issuable upon exercise of the Company's stock options and share based awards of 0.2 million, as the effect would be anti-dilutive. For the three and six months ended June 30, 2010, the weighted average number of common shares outstanding excluded shares issuable upon exercise of the Company's stock options and share based awards of 3.4 million and 1.9 million, respectively, as the effect would be anti-dilutive. Additionally, for the six months ended June 30, 2010, the weighted average number of common shares outstanding excluded 0.3 million shares issuable upon conversion of the Company's convertible notes, which were repaid in 2010. |

| Commitments and Contingencies | 10. Commitments and Contingencies
Litigation—The Company periodically becomes involved in various claims and lawsuits that are incidental to its business. In the opinion of Company management, after consultation with counsel, other than the legal proceedings discussed below, there are no matters currently pending that would, in the event of an adverse outcome, materially impact the Company's consolidated financial position, results of operations or liquidity.
SEC Subpoena—On June 2, 2011, the Company received a subpoena from the SEC requesting certain documents from 2007 through the date of the subpoena, including in particular documents related to the Company's tax accounting and reporting. While the Company believes this investigation may in part relate to a former employee's complaints received in the past, which the Company previously investigated with the assistance of outside counsel and a forensic accounting firm, finding no material issues, the Company cannot at this time predict the scope or the outcome of this investigation. The Company understands that its independent registered public accounting firm and one of its consultants have also received subpoenas related to the Company's tax accounting and reporting during this period and its investigation into this complaint. The Company is cooperating and intends to continue to cooperate fully with the SEC with respect to its investigation. Mexico Litigation—One of the Company's subsidiaries, SpectraSite Communications, Inc. (“SCI”), is involved in a lawsuit brought in Mexico against a former Mexican subsidiary of SCI (the subsidiary of SCI was sold in 2002, prior to the Company's merger with SCI's parent in 2005). The lawsuit concerns a terminated tower construction contract and related agreements with a wireless carrier in Mexico. The primary issue for the Company is whether SCI itself can be found liable to the Mexican carrier. The trial and lower appellate courts initially found that SCI had no such liability in part because Mexican courts do not have the necessary jurisdiction over SCI. In September 2010, following several decisions by Mexican appellate courts, including the Supreme Court of Mexico, and related appeals by both parties, an intermediate appellate court issued a new decision that would, if enforceable, reimpose liability on SCI. In its decision, the intermediate appellate court identified potential damages of approximately $6.7 million, and on October 14, 2010, the Company filed a new constitutional appeal to again dispute the decision. As a result, at this stage of the proceeding, the Company is unable to determine whether the liability imposed on SCI by the September 2010 decision will survive or to estimate its share, if any, of that potential liability if the decision survives the pending appeal. XCEL Litigation—On June 3, 2010, Horse-Shoe Capital (“Horse-Shoe”), a company formed under the laws of the Republic of Mauritius, filed a complaint in the Supreme Court of the State of New York, New York County, with respect to Horse-Shoe's sale of XCEL Telecom Private Limited (“XCEL”) to American Tower Mauritius (“AT Mauritius”), the Company's wholly owned subsidiary formed under the laws of the Republic of Mauritius. The complaint names AT Mauritius, ATI and the Company as defendants, and the dispute concerns the timing and amount of distributions to be made by AT Mauritius to Horse-Shoe from a $7.5 million holdback escrow account and a $15.7 million tax escrow account, each established by the transaction agreements at closing. The complaint seeks release of the entire holdback escrow account, plus an additional $2.8 million, as well as the release of approximately $12.0 million of the tax escrow account. The complaint also seeks punitive damages in excess of $69.0 million. The Company filed an answer to the complaint in August 2010, disputing both the amounts alleged to be owed under the escrow agreements as well as the timing of the escrow distributions. The Company also asserted in its answer that the demand for punitive damages is meritless. The parties filed cross-motions for summary judgment concerning the release of the tax escrow account and, in January 2011, the court granted the Company's motion for summary judgment, finding no obligation for the Company to release the disputed portion of the tax escrow until 2013. Other claims are pending. In March 2011, Horse-Shoe filed a motion for summary judgment seeking disbursement of $5.3 million of the holdback escrow account that it claims is undisputed. The court denied Horse-Shoe's motion in May 2011. The Company is vigorously defending the lawsuit. AT&T Transaction—The Company has an agreement with SBC Communications Inc., a predecessor entity to AT&T Inc. (“AT&T”), for the lease or sublease of approximately 2,500 towers from AT&T between December 2000 and August 2004. All of the towers are part of the Company's securitization transaction. The average term of the lease or sublease for all sites at the inception of the agreement was approximately 27 years, assuming renewals or extensions of the underlying ground leases for the sites. The Company has the option to purchase the sites subject to the applicable lease or sublease upon its expiration. Each tower is assigned to an annual tranche, ranging from 2013 to 2032, which represents the outside expiration date for the sublease rights to that tower. The purchase price for each site is a fixed amount stated in the sublease for that site plus the fair market value of certain alterations made to the related tower by AT&T. The aggregate purchase option price for the towers leased and subleased was approximately $475.0 million as of June 30, 2011, and will accrete at a rate of 10% per year to the applicable expiration of the lease or sublease of a site. For all such sites purchased by the Company prior to June 30, 2020, AT&T will continue to lease the reserved space at the then-current monthly fee which shall escalate in accordance with the standard master lease agreement for the remainder of AT&T's tenancy. Thereafter, AT&T shall have the right to renew such lease for up to four successive five-year terms. For all such sites purchased by the Company subsequent to June 30, 2020, AT&T has the right to continue to lease the reserved space for successive one year terms at a rent equal to the lesser of the agreed upon market rate and the then current monthly fee, which is subject to an annual increase based on changes in the Consumer Price Index.
ALLTEL Transaction—In December 2000, the Company entered into an agreement with ALLTEL (which completed its merger with Verizon Wireless in January 2009) to acquire towers from ALLTEL through a 15-year sublease agreement. Pursuant to the agreement with ALLTEL, as amended, the Company acquired rights to a total of approximately 1,800 towers in tranches between April 2001 and March 2002. The Company has the option to purchase each tower at the expiration of the applicable sublease, which will occur in tranches between April 2016 and March 2017 based on the original closing date for such tranche of towers. The purchase price per tower as of the original closing date was $27,500 and will accrete at a rate of 3% per annum through the expiration of the applicable sublease. The aggregate purchase option price for the subleased towers was approximately $66.1 million as of June 30, 2011. At ALLTEL's option, at the expiration of the sublease, the purchase price would be payable in cash or with 769 shares of the Company's Common Stock per tower. |

| Description of Business, Basis of Presentation and Accounting Policies [Abstract] | |
| Change In Presentation Policy [Text Block] | Changes in Presentation—Changes have been made to the presentation of gross purchases and sales of short-term investments within the condensed consolidated statements of cash flows for the six months ended June 30, 2010. |
| Consolidation Policy [Text Block] | Principles of Consolidation and Basis of Presentation—The accompanying condensed consolidated financial statements include the accounts of the Company and those subsidiaries and joint ventures in which it has a controlling interest. Investments in entities that the Company does not control are accounted for using the equity or cost method, depending upon the Company's ability to exercise significant influence over operating and financial policies. |
| Significant Accounting Policies And Use Of Estimates Policy [Text Block] | Significant Accounting Policies and Use of Estimates—The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results may differ from those estimates, and such differences could be material to the accompanying condensed consolidated financial statements. The Company considers events or transactions that occur after the balance sheet date but before the financial statements are issued as additional evidence for certain estimates or to identify matters that require additional disclosure. |
| Concentration Risk Disclosure Text Block | Concentrations of Credit Risk—The Company is subject to concentrations of credit risk related to its cash and cash equivalents, notes receivable, trade receivables and deferred rent asset. The Company mitigates its risk with respect to cash and cash equivalents by maintaining its deposits and contracts at high quality financial institutions and monitoring the credit ratings of those institutions.
The Company derives the largest portion of its revenues, corresponding trade receivables and the related deferred rent asset from a small number of customers in the telecommunications industry. Approximately 54% of its revenues are derived from four customers. In addition, the Company has concentrations of credit risk in certain geographic areas.
The Company mitigates its concentrations of credit risk with respect to notes and trade receivables and the related deferred rent asset by actively monitoring the credit worthiness of its borrowers and customers. In recognizing customer revenue, the Company must assess the collectability of both the amounts billed and the amounts recognized on a straight-line basis. This assessment takes customer credit risk and business and industry conditions into consideration to ultimately determine the collectability of the amounts billed. To the extent the amounts, based on management's estimates, may not be collectable when billed, recognition is deferred until such point as the uncertainty is resolved. Any amounts which were previously recognized as revenue and subsequently determined to be uncollectible are charged to bad debt expense.
The Company's largest international customer is Iusacell, which is the brand name under which a group of companies controlled by Grupo Iusacell, S.A. de C.V. (“Grupo Iusacell”) operates. Iusacell represented approximately 4% of the Company's total revenue for six months ended June 30, 2011. Grupo Iusacell has been engaged in a refinancing of a majority of its U.S. Dollar denominated debt, and in connection with this, two of the legal entities of the group, including Grupo Iusacell, voluntarily filed for a pre-packaged Concurso Mercantil (a process substantially equivalent to Chapter 11 of U.S. Bankruptcy Law) with the backing of a majority of their financial creditors in December 2010 and subsequently concluded the process in April 2011 after a Mexican court ruled in favor of the refinancing plan presented by the two legal entities. As of June 30, 2011, Iusacell notes receivable, net, and related assets (which include financing lease commitments and a deferred rent asset that are primarily long-term in nature) were $20.9 million and $61.0 million, respectively. |
