and Broadcast Wireless Services
API Technologies’ model CMF905 is a wireless communications bandpass filter that eliminates Advanced Wireless Service
(AWS) interference at Electronic News Gathering-Receive Only (ENG-RO) BAS channel A7. The CMF905 is designed for use by
television stations, broadcast wireless services, ENG-RO and cellular base stations transmit signals to mitigate the interference
of cellular frequencies above 2110.6 MHz. As mandated by the FCC, cellular service providers must make timely adjustments in
their systems to reduce interference with television station communication links using mobile news gathering services.
The close proximity of the lower AWS1 frequency block (2110.6 to 2121.5 MHz) can cause interfering signals to the BAS
Channel A7 communications link. This is especially common in metropolitan areas with congested electromagnetic spectrums.
API’s wireless communications filter provides 60 dB of rejection from 2110.6 MHz to 2121.5 MHz (AWS1), while passing BAS
channel A7 frequencies (2097.5 MHz to 2109.5 MHz). This allows local television stations the ability to communicate clearly
using voice and video to and from their mobile units without experiencing interference.
