Abstract
Operators of wireless communication systems operating in the same geographic area are able to build networks on neighboring/adjacent bands, even if one of the systems is using a TDD mode and the other systems is using a FDD mode without using excessive large guard bands. A beaconing mechanism with signaling is used to impose an exclusion zone and power restriction, antenna direction, and other operational parameters. A newcomer operator is able to get an accurate knowledge of the interference to and from the sites of the AP of the existing operator so that the newcomer can deploy his APs without causing interference to the existing APs.
