Hi Sylvain, I asked a colleague of mine about nanoBTS model-numbers, he gave me a list of available models that he got from IpAccess when he was looking to buy some BTSs from them a while ago. They seem to use different internal and external model-numbers for the non-EDGE oval models, maybe not for the EDGE models; I've put in the three external->internal number correspondences I know for definite: Model no. IpAccess ref.

HTH, Mike H
