| System advantages |
The KR900 radio modem puts an end to reduced transmission range and limited coverage previously associated with license free spread spectrum radio systems. Although conventional repeaters can be used to increase range and coverage, they incur a penalty of 50% or greater reduction in data throughput and an equivalent increase in data latency. Conventional repeaters also sacrifice antenna gain because only a single omni directional antenna can be used to access both the master radio as well as all the remote sites. The KR900 now redefines the benchmark with a combination of its KwikStream™ high speed, low latency repeater and its LinkXtend™ dual antenna network bridge. |
