Mr. Goren,

Local Loop is a telephone industry term for the area in which all home or office phones are connected to a local telephone company switch. Local Loops are sometimes referred to as the "last mile" of wire between the telephone company and a home or business, although it is not necessarily a mile in distance. Wireless Local Loop (WLL), as one might guess, is the same concept but without the wire and where wireless infrastructure equipment replaces the telephone company's wire-based switch equipment. Although it uses wireless phones, WLL emphasizes their use in a small area, such as a house, rather then being completely mobile.

The most obvious application or market for WLL is to provide telephone service for underdeveloped countries. With WLL, a country can avoid the cost of having to place miles of wire and instead can simply place wireless infrastructure equipment to process calls. India and Russia are 2 examples of countries which have decided to implement WLL to supplement their communications capacity.

Other applications for WLL are still being explored, but it is possible that future communities built in the United States could completely bypass wire-based communications and simply have a CDMA WLL installed with CDMA's near wire-sound quality. Another question regarding the future of WLL is to what extent will existing communities in the United States start to overload their current wire-based telephone infrastructure? Since CDMA WLL can offer data services at ISDN speeds (and maybe even higher), CDMA WLL could provide a cost-effective means of adding additional voice and data capacity.
