To be more clearer, I have two BTSs 900 BTS and 1800 at each site and the TRXs are already there in the cabinets. There is no any interconnection between these two BTS, therefore, can I implement concentric cells without changing any physical and do some configuration at the OMCR. I am not sure about Huawei but what about alcatel can you suddenly switch to concentric cell without doing any operation at the site if the two BTS are already in a functioning state?
Thanks
