Kingtone JIMTOM® Wireless Channel Selective Bi-direction Amplifier are cost effective and reliable solutions designed to extend and improve the coverage area of Tetra BTS. Especially for where the radio environment is complex and interference is strong area. The wireless channel selective BDA amplifies and select wanted carriers in both directions, uplink and downlink. With its FPGA based high performance channel selective digital filter, high linearity and efficient PAs, robust operating and maintenance system, the BDA is a powerful and economic solution to enhance the BTS coverage area. Typical application scenarios of this BDA: tunnels, buildings, subways, and outdoor scenarios such as stadiums, rural areas and dense urban areas.
With high selectivity character, Channel Selective Repeater provides superior out-of-channel suppression to avoid interfering with adjacent channels.
It can be applied to the urban RF environment where suffered from interference caused by complicated donor signals.
The Channel Selective Repeater is also an ideal solution for rural area.
The Channel Selective Repeater is suitable for the network with base-band hopping or synthesizer hopping less than 16 channels.
410-415MHz for Uplink (radios to repeaters) and 420-425MHz for Downlink (repeaters to radios)
