Huawei’s new RNC seems to be copy of Ericsson RNC. Why do I say so? Well, it has inherited two major limitations of Ericsson RNC. It has very primitive load sharing as it can only be done on subrack level. They can connect 50 BTS per subrack, the traffic balancing can only be done per 50BTS group. The other issue symmetrical Iub interface, which typically is effective only with voice traffic. The current trend is towards data traffic, where share between UL and DL is 20% and 80%. One more thing about capacity; Huawei is saying that their RNC is having 3.2Gbps data throughput. Well, it’s 1.6Gbps per direction. A bit miss leading message I would say.
