If I’ve paid for a femtocell, I might reasonably think I could take it with me on my travels and use it to get great coverage, performance (not to mention low rates), wherever I go.
The traditional GSM/UMTS cellular operators have mandated that femtocells connect directly to existing core network elements using a standard Iu interface. This allows seamless handover between femtocells and existing 2G/3G cellular networks, with the same services, phone numbers and ease of use that we are all used to. It is also compatible with existing mobile phones - no changes or upgrades are required.
Energy Consumption of Femtocells – are they Green?
With growing awareness of climate change, increasing energy prices and close scrutiny of operating costs, there is good reason to consider whether femtocells would reduce overall power consumption or not and add to our carbon footprint.
