Overlapping coverage sectored/omni antenna architecture for dual standard support with handoff to backward-compatible standard during antenna/RF path/system failure
First Claim
1. For use in a wireless communications system, an apparatus for supporting dual standards comprising:
- a sectored antenna system for a coverage area; and
an omni antenna system for the coverage area, wherein the sectored antenna system is employed for wireless communications utilizing a first standard within the coverage area and the omni antenna system is employed for wireless communications utilizing a second standard within the coverage area.

Abstract
Two radio systems are provided for each coverage area within a wireless communications system, each radio system supporting a different wireless communications standard with at least one of the standards being compatible with the other (such as the backward-compatibility of either of 1xEV-DO or 1xEV-DV with IS-2000). Both of the radio systems may have a sectored configuration for selected coverage areas while a combination of sectored and omni configurations are employed for the radio systems for other coverage areas. When communications with a mobile station utilizing one standard fails within a coverage area due to antenna, radio frequency path, or radio system failure, wireless communications with that mobile station is automatically resumed utilizing the other, compatible wireless communications standard.
