Deferred Costs, Capitalized, Prepaid, and Other Assets Disclosure [Abstract]
Escrow Deposits	Escrow Deposits Escrow deposits are considered restricted cash as the deposits are restricted from use until the terms of the escrow agreement are met. Restricted cash is recorded as escrow deposits and a contingent liability on the Company’s Consolidated Balance Sheets. A reduction in the contingent liability and escrow deposits will be recognized for each county as the Company delivers the cleared 900 MHz Broadband Spectrum and the associated broadband licenses. Escrow deposits classified as current assets on the Company’s Consolidated Balance Sheets are related to the portion of the obligations of the escrow agreement that are expected to be met within a twelve-month period beginning December 31, 2025. Obligations not expected to be completed within this twelve-month period are classified as non-current assets. In connection with the Lower Colorado River Authority (“LCRA”) Agreement entered into in April 2023 (the “Original LCRA Agreement”), the Company and LCRA entered into an escrow agreement. Pursuant to the escrow agreement, the escrow funds deposited from LCRA payments to the Company shall be held and invested in a money market deposit account. All interest and other income earned shall be allocated to the Company, payable with the final distribution of the escrow funds. The escrow funds shall be distributed upon written request by both the Company and LCRA pursuant to the terms within the Original LCRA Agreement. In December 2023, the Company received $15.0 million, of which $7.5 million was deposited in an escrow account. As of December 31, 2025, the Company has classified $0.9 million as short-term escrow deposits on the Consolidated Balance Sheets, inclusive of accrued interest and escrow releases for delivered 900 MHz Broadband Spectrum and the associated broadband licenses. In June 2025, the Company entered into an agreement with an incumbent to retune and acquire wireless licenses for approximately $28.0 million. In connection with this agreement, the Company entered into an escrow agreement. Pursuant to the escrow agreement, the escrow funds deposited from the Company payments due to the incumbent shall be held and invested in a money market deposit account. All interest and other income earned shall be allocated to the incumbent, payable with the final distribution of the escrow funds. The escrow funds shall be distributed upon written request by both the Company and the incumbent pursuant to the terms within the escrow agreement. Once the escrow funds are distributed to the incumbent, the payments are recorded as spectrum receivable on the Company’s Consolidated Balance Sheets. In July 2025, the Company deposited $14.0 million into the escrow account. As of December 31, 2025, the Company has classified $7.5 million as short-term escrow deposits on the Consolidated Balance Sheets, inclusive of accrued interest and escrow releases to the incumbent, which are subsequently recorded as spectrum receivable on the Company’s Consolidated Balance Sheets.
