AWS Cost Sharing Clearinghouse

Assess your cost sharing obligations

Registering with the CTIA Clearinghouse ensures compliance with FCC rules and reimbursement of your AWS relocation investments.


Sharing the relocation costs

In making spectrum available for AWS, the FCC rules require that new AWS licensees pay the costs associated with relocating the legacy systems operating in the 2.1 GHz band. The new AWS licensees will need to invest significant sums to relocate the incumbent BRS and FS systems. The FCC requires new entrants to share the burden of funding these relocation costs by reimbursing a proportion of the relocation costs that have already been paid by others.

What is the CTIA Cost Sharing Clearinghouse?


Designated in 2006 by the Federal Communications Commission, the CTIA Spectrum Clearinghouse ensures objective and equitable cost sharing of relocations in the 2110–2200 MHz spectrum band. It provides the database management and technical analysis to all affected licensees, whether incumbent users of the spectrum or newly licensed entities, in the relocation and cost-sharing process. The CTIA Spectrum Clearinghouse is tasked with the identification and notification of cost-sharing obligations in the Advanced Wireless Services (AWS)/Mobile Satellite Services (MSS) spectrum bands.

The CTIA Clearinghouse has hired Comsearch to handle the day-to-day operations of its clearinghouse. This includes the determination of when cost-sharing activity is triggered and the notification to the affected parties of such an event. CTIA Clearinghouse has developed and launched a web-based application to calculate and manage cost-sharing activity for participating licensees. This web-based tool will enable the CTIA Clearinghouse to accept and process cost-sharing requests with minimal delay. By registering with the CTIA Clearinghouse, AWS licensees can comply with FCC rules and ensure reimbursement of their relocation investments by new entrants.
