undant. Hybrid solutions that deliver the benefits of both wind and solar technologies will therefore be more common than wind only solutions at standard base station loads. Other alternatives include Pico-hydro, biodiesel and fuel cells [11]. Another effective way to improve the energy efficiency of telecommunications equipment is to use remote radio head technology. This technology involves positioning the radio aspects of the base station - including the transceiver and power amplifier - close to where the antenna is mounted, which is typically at the top of the tower. This technology can reduce the power loss incurred when the signal is transmitted from the bottom of the tower by a long feeder cable (>50 m for some towers) to the antenna. Other alternatives include RAN and Transmission Network sharing, outdoor BTS, and SO on [11]. 13.6.3 Green Power Industry Trends Some current industry trends are as follows: Telenor Pakistan and Grameenphone (Telenor subsidiary) in Bangladesh launched solar powered BTS sites in 2009. Digicel and Safaricom Kenya are providing innovative mobile phone charging solution for their customers. ZTE has produced a solar phone. Infrastructure vendors like Nokia Siemens Networks, ZTE, Huawei, and SO on, are providing solar powered base stations. GSMA forecasts that by 2012 there will be 520 000 off-grid diesel base stations and 118 000 green renewable energy base stations. GPM is on target to complete projects for 15 operators across 1000 solar, wind and biofuel base stations by Q4 2010. 13.7 Media and Telecom Convergence The mobile phone is becoming the "third screen" for users and day by day they demand more from it. The first two screens, as we are all familiar with, are TV and Computer respectively. The users are demanding very much the same level of experience from cell phones as they are getting from TV and the computer. We all know that the customers care less about the underlying technology (i.e., GSM, CDMA, and OFDMA) and more about the content they can get from their respecti
