tecore wireless systems announced the launch of its pre-ims voip/sip enabled gsm base station to be showcased at this year’s 3gsm world congress.

inset shows a current tecore base station - the corecell cdma base station.

the bts-4000rm delivers up to 64 high powered gsm/gprs/edge voice and data channels occupying as little as 5u of a standard 19� telecommunications rack. the bts-4000rm base station eliminates the need for traditional bsc, trau and pcu elements, embedding these functions within the base station platform

with the launch of the bts-4000rm, tecore also introduces network interface enhancements to its gsm base station product line. this includes the internal translation from a traditional gsm ran to an all ip sip-enabled network interface. thus, the bts-4000rm supports direct connection to a pre-ims network. added capabilities include transcoder-free operation to minimize network bandwidth, and direct routing of local ip call traffic to optimize overall backhaul utilization. specifically targeting applications requiring compact radio access solutions, the bts-4000rm offers flexible network integration and deployment capabilities while providing macro rf coverage, capacity and performance.
