That's the trouble with GSM, the cell (or picocell) is just part of the infrastructure required. A cell is actually a BSC (basetation controller). BSC's are controlled by MSC's (Mobile switching centre), an MSC will control multiple BSCs and MSC talk to each other. We're in SS7 land now. You also need an HLR (home location register), SMSC (if you want your users to do SMS) and then all the GPRS bits for MMS/data/etc. IP.Access's picocell uses IP backhaul so can be deployed easily in remote sites. They cost around GBP 2,000. In the UK there are between 7 and 12 low power GSM national licenses becoming available (in the old GSM/DECT guard bands). Need to get you intent to bid into Ofcom (and payment) on the 21st b/n 10am a 5.30pm.
