![]() ![]() The Commission tasked the TA with administering the technical and financial aspects of the band reconfiguration process to ensure that the Commission's goals would be achieved with minimal disruption to licensees, particularly public safety entities. To facilitate the rebanding process, the Commission has provided for the creation of an independent 800 MHz Transition Administrator (TA) to administer the transition and review expenditures. For Rebanding Questions/Comments e-mail or contact the 800 MHz Transition Administrator. Implementation of 800 MHz band reconfiguration is a top priority of the Public Safety and Homeland Security Bureau (see chart below). This plan is designed to protect the lives of first responders and other emergency personnel and fulfills the Commission's obligation to promote safety of life and property through the use of wire and radio communications. To address a growing problem of harmful interference to 800 MHz public safety communication systems caused by high-density commercial wireless systems, the Commission in July 2004 adopted a comprehensive plan to reconfigure the band. The 800 MHz band is also home to commercial wireless carriers and private radio systems. Model-C122I Isolator, supports 5.4-5.9 GHzĬontact To know Circulator manufacturers, pl.Public safety radio systems (such as those used by police, firefighters and emergency medical technicians) operate in several portions of the 800 MHz band, which consists of spectrum at 806-824 MHz paired with spectrum at 851-869 MHz. ![]() Model: C121I Isolator, supports 4.9-5.4GHz frequency of operation.
