1. A base station for establishing an air interface in a shared channel communication system within a confined space for wireless communication, the base station comprising:
- a first antenna having a first antenna pattern and communicating through an air interface through a first communication sector;
at least one additional antenna having a second antenna pattern and communicating through an air interface in a second communication sector;
whereinthe first and the second sector provide a significant pattern of overlap, and wherein the antenna patterns provide significant spatial diversity.

Abstract
A base station for establishing a picocell is configured so as to provide multiple sectors, with spatial diversity between sectors. The combination of the multiple sectors and the spatial diversity reduces signal power requirements in the air interface within a confined space and provides improvements in quality of service.
