Abstract

An embodiment of the present invention provides an apparatus, comprising at least one transceiver operable in a wireless personal area network (WPAN), wherein the at least one transceiver is equipped with the directional antennas adapted to point substantially vertically towards a horizontal reflecting surface, such as a ceiling, and with an antenna pattern specifically designed to control the interference levels.

Claims

1. An apparatus, comprising:

at least one transceiver operable in a wireless personal area network (WPAN), wherein said at least one transceiver is equipped with directional antennas radiating in a vertical direction towards a horizontal reflective surface and with an antenna pattern specifically designed to control interference levels; and

wherein said horizontal surface is a ceiling and said antenna pattern is configured for a signal to be reflected off said ceiling and cover a required area of said WPAN and reduce interference for adjacent WPANs.

2. The apparatus of claim 1, wherein said at least one transceiver is a millimeter (mm) Wave transceiver.

3. The apparatus of claim 1, wherein said antenna pattern reduces inter-symbol interference (ISI) to enable a simplified baseband implementation to reduce equalization complexity and coding complexity.

4. A method, comprising:

operating a transceiver in a wireless personal area network (WPAN) and using directional antennas to transmit towards a ceiling with an antenna pattern specifically designed to control the interference level; and

wherein said antenna pattern is configured for a signal to be reflected off said ceiling and cover a required area of said WPAN and reduce interference for adjacent WPANs.

5. The method of claim 4, further comprising operating said transceiver in a millimeter (mm) Wave frequency band.

6. The method of claim 4, wherein said antenna pattern reduces inter-symbol interference (ISI) to enable a simplified baseband implementation to reduce equalization complexity and coding complexity.

7. A system for wireless personal area network communications, comprising:

a plurality of transceivers associated with a plurality of devices operable in a wireless personal area network (WPAN), wherein said transceivers are equipped with directional antennas radiating substantially vertically toward a horizontal reflecting surface with the antenna patterns specifically designed to control the interference levels when said plurality of devices are communicating with each other via said transceivers; and

wherein said plurality of transceivers are a millimeter (mm) Wave transceiver and said horizontal surface is a ceiling.

8. The system of claim 7, further comprising additional adjacent WPANs and wherein said antenna patterns are configured for a signal to be reflected off said ceiling and cover a required area of said WPAN and reduce interference significantly for said additional adjacent WPANs.

9. The system of claim 8, wherein said signal pattern enables a simplified baseband implementation to reduce equalization complexity and coding complexity.
