mobile technology

No doubt partly regurgitated from a Nokia press release, but some interesting comments in there:

Mobile networks are eyeing a new(ish) technology that can put a mini mobile base station in your home.  This is being sold on the basis of providing better connections, especially high speed data connections, to those who otherwise struggle to get a decent signal.  Interestingly the units, generically known as femtocells, use an existing broadbandi connection to route the calls from the mobile phone.  This is not to be confused with VoIPi, where, at least for computer to computer connections, the call is effectively free.  In the case of femtocells the calls are routed via the Internet to the mobile providers networki and onwards as per a normal mobile call.  The calls, therefore, are likely to be charged at similar rates to other mobile calls.
