Microcellular RF transmission system with baseband signal delivery via a wireline connection
First Claim
1. A base station, where antenna and digital functions of a base station are separated, the base station comprising:
- a master base transceiver station (MBTS); and
a separate base station remote including all radio frequency (rf) components.

Abstract
Techniques are described for splitting a base transceiver station into digital and rf functions. With relatively low cost simulcasting clusters of rf remotes located to define coverage areas and master base transceiver stations connected to the rf remotes by suitable wireline connectors, such as Ti lines, the bulk of the digital functions can be located anywhere that is desired. Numerous, small, low cost, low power rf remotes may be advantageously mounted on existing structures such as light poles, telephone poles, and the like to achieve desired areas of coverage cost effectively and with a high degree of flexibility with respect to meeting future increases in need for additional capacity.

12. A wireless communication network comprising:
-
a first plurality of m clusters of simulcasting base station remotes per cluster which communicate with a master base station (MBTS) by a wireline connection; and
a controller for causing the plurality of clusters to be reconfigured as a second plurality of m+1 simulcasting clusters.

13. A method of wireless communication comprising the steps of:
-
performing digital call processing in a base station kernel;
providing a processed digital signal from the base station kernel to a base station mother which conditions the processed signal and transmits it on a T1 line to a base station remote which does all the radio frequency (rf) signal processing; and
transmitting an rf signal with the base station remote. - View Dependent Claims (14)

15. A method of reconfiguring a wireless communication system comprising the steps of:
-
setting up an original network having a plurality of clusters or remotes of a given size to support an originally desired coverage plan; and
reconfiguring the original network by reducing the size of the plurality of clusters to meet additional capacity demand.
