Feasability of CDMA technology for Providing WLL Technology in Pakistan

Pakistan is a country with scattered population, limited demand, large average access distances, poor infrastructure, low affordability. These are the factors that have restricted the phone coverage in Pakistan to 30 % and made the installation of a fixed line telephone network prohibitively expensive. Wireless Local Loop is an emerging technology that connects subscribers to the Pubic Switched Telephone Network using radio signals instead of fixed copper or optical fibre lines, which is one of the best possible solution to this problem. Compared to the deployment of wired alternative, WLL offers rapid deployment, reduced construction costs, low network maintenance, low network extension costs, etc. There are various technologies through which WLL can be implemented & no standards have yet emerged. So the selection of appropriate technology is mandatory, here viability of CDMA based WLL solution is discussed.
