Abstract
An omni-directional antenna supporting simultaneous transmission/reception, from the same AP, on multiple frequencies, allowing each AP to communicate using each possible frequency. Each AP multiplexes its outgoing signals onto its transmitting antenna, and de-multiplexes its incoming signals from its receiving antenna. The transmitting and receiving antennae are each substantially located in each other's NULL zone (or one is in the NULL zone of the other). The AP can transmit/receive on many distinct frequencies without needing more antennae.
