Licenses and Leases by Market
The Federal Communications Commission has granted 22 broadband licenses to Clarendon Foundation: 21 Educational Broadband Service (EBS) licenses and one Nonexclusive Nationwide (NN) 3.65 Gigahertz license.
Each EBS license has four channels (22.5 Megahertz total). Clarendon leases 95 percent of its spectrum to wireless operators for commercial broadband wireless access service, and retains the remaining 5 percent to serve accredited educational institutions in each market. While 5 percent may not seem like a substantial amount, since the EBS channels can be reused in a cellular network, the aggregate amount is sufficient to serve multiple Receive Site schools and colleges.
The 3.65 GHz license has 50 Megahertz of spectrum. This license is best suited to provide broadband wireless access to underserved areas where outdoor channels are used. It can be used in any area of the country except where it would interfere with pre-existing satellite earth stations.

There are over 1700 EBS Licensees. There are also many commercial Broadband Radio Service (BRS) licensees. These two types of licenses comprise the spectrum referred to as the 2.5 Gigahertz band. In this section, you can also access a database of the licenses in this band, which has been enhanced with updated census information.
Telecommunications Mapping Tools
This section contains links to a variety of interactive maps:
- The FCC has added an interactive GSA map for each EBS license in the Universal Licensing System.
- Wireless operators Clearwire and Xanadoo provide online maps of the coverage area for each market that has been deployed so that potential customers can determine whether service is available.
- The WiMAX Forum has posted a global map of fixed and mobile WiMAX deployments on its website.
- Connected Nation is producing state maps that allow policy makers to create customized views of broadband infrastructure by county and enable residents to determine the availability of broadband service by street address.
- Spectrum Bridge has developed a mapping tool that displays search results of available bandwidth on the world's first online real-time marketplace for licensed radio spectrum.
- ComSearch provides an online mapping interface for 3.65 GHz operators that can be used to identify satellite earth station and federal radiolocation station protection zones, and locate nearby 3.65 GHz systems. This information is used to design a network that avoids the potential for harmful electronic interference.
- The Rural Development office of the U.S. Department of Agriculture provides a map search tool for applicants to use to verify whether broadband projects have been funded in their communities.
