The efficiency of radio basestations, defined as the amount of RF energy they radiate divided by the AC power supplied to do so, is increasing year-on-year, from 3 per cent in 2003 to 12 per cent in 2009 and possibly to 25 per cent in 2015. But we still need to establish the optimum cell size (macro vs pico vs femto) taking into account backhaul power requirements, and to ascertain whether femtocells or relays or a mixture of these will prove the most energy-efficient way to extend cell coverage.

    There are two main access policies (open and closed) to Femtocell Access Points (FAPs), being closed access the customers favorite. However, closed access is the root cause of crosstier interference in cochannel deployments of two-tier networks (i.e., macrocells and femtocells). Further, the...
