K Series: KR900 Advanced Spread Spectrum Industrial Data Radio

Range and Coverage

The Trio KR900 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.

The KwikStream™ repeater is used in Point to Multipoint (PTMP) systems where one repeater with a single omni antenna is sufficient to provide coverage to all remote sites, but where the sheer number of remote sites, or the user data necessitate high data throughput with the lowest possible latency.

In situations where a repeater is needed to extend the range of a Point to Point (PTP) link, but where a single omni antenna at the repeater cannot provide the desired transmission range, Trio’s LinkXtend™ dual antenna bridge will allow the use of dual directional antennas with much higher gain.

If more than one repeater is required for wide area PTMP coverage or where remote sites may be difficult to reach, then these repeaters are configured as bridges to optimize data throughput by ensuring that all radios in the system remain synchronized. Dual antenna LinkXtend™ bridges equipped with one high gain directional antenna for uplink access, as well as an omni antenna for downlink communications with the remote sites, can provide ultra long range coverage.

Due to restrictions on maximum allowable signal levels in license free bands, the transmitter power for each of the two antenna ports can be individually adjusted in line with the two different antenna gains, to maximize the transmitted signal levels from both antennas.

With a combination of bridges and MultiStream™ data routing, the KR900, allows networks carrying multiple simultaneous user applications, with totally separate protocols, to be extended literally without limit,.

Any Trio KR900 may be configured as a KwikStream™ high speed low latency repeater or as a LinkXtend™ network bridge with MultiStream™
