yeah that’s what we call here also in Ericsson.. Here in Australia, we have RBS200 too, which are now being modernized to RBS2216 and co-loc with an RBS3206 or Ericsson Node B or Ericsson 3G BTS. What I know the BTS for LTE is called an eNode B.
BTS/base transceiver station/base station is generic to all network but to be specific of course depending on vendor’s model and technology, like what you said for 3G is Node B. So how about if it’s CDMA? TDMA? CDMA EV-DO? TD-SCDMA? WiMax? I don’t know, but generic, its BTS.
