Abstract
Apparatus for a wireless communication network, comprises: a directional beam antenna, an antenna controller for directing said directional beam antenna in an optimum signal quality beam direction, and coding means operable at two or more coding rates, to switch between said rates responsive to said controller changing said antenna beam direction.
Claims38
Apparatus for a wireless communications network, comprising:
- an antenna system capable of both omnidirectional and directional operation;
- an antenna controller for directing said antenna system to operate with omnidirectional operation and, in response to said onmidirectional operation, directing said antenna system to operate in an optimum signal quality direction;
- and
- coding means operable at two or more coding rates, and responsive to said antenna controller initiating a change in a direction of said antenna system to switch between said two or more coding rate.
