But we never hear of fixed wireless telephone system. It means no incoming wiring from outside, and no internal wiring. The telephone set becomes cordless within a locality (short range). There are also no cables from the exchange, a huge saving in capital costs, and a relief on operation and maintenance budgets.

Its feasibility is not known to the writer of this letter, and information on its use and application in other LDCs is not easily available. It will not be popular in the developed countries, but may be cost-effective in under-developed countries for the middle class and the rural population. The big mobile operators would not advertise it. The circuitry should be much simpler than the standard mobile telephone, which has wide roaming capabilities. The fixed wireless set is confined to the a limited radius around a subscriber's site.

Can we have some more general information on this technology (if it exists at all)?
