Trends in telecommunication services provision: Powerline network can provide alternative for access in developing countries

The key problem in providing communication services in developing countries like Tanzania have been identified as using standard network such as PSTN, GSM cellular in different areas which have been designed for high capacity. As the results the cost of telecommunication provision has tended to be at high cost compared to the actual income of the citizen. According to the international telecommunication union (ITU) 12% of the global population lives in Africa, yet Africans have access to only 2% of the world telephones, less than I person in 300 in sub-saharan Africa has telephone. For example, in Tanzania, the country with four GSM cellular mobile companies, 2 fixed telephone lines, 8 public data network and 13 Internet Services Provider still has a teledensity of 1.42 for mobile and 0.90 fixed line. Also this has identified to be the same trend in other Affican countries. In developed countries this have identified to be not the case because a number of communication network have been implemented such as WCDMA, GSM/GPRS, CDMA2000 etc which have got a key features of global economies of scale and the platform to support both voice and non voice. It has been identified that the communication trend now is supporting more data than voice, which demands high bandwidth and bandwidth is money which can not be afforded by developing countries customers like Tanzania.
