Abstract

An embodiment of the present invention provides an apparatus, comprising at least one transceiver operable in a wireless personal area network (WPAN), wherein said 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 adapted to point in the vertical direction towards a horizontal reflective surface and with an antenna pattern specifically designed to control the interference levels.

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 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.

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

5. 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.

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

7. The method of claim 5, 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 significantly for adjacent WPANs.

8. The method of claim 7, wherein said antenna pattern reduces inter-symbol interference (ISI) to enable a simplified baseband implementation to reduce equalization complexity and coding complexity.

9. A machine-accessible medium that provides instructions, which when accessed, cause a machine to perform operations comprising:

controlling the operation of a transceiver in a wireless personal area network (WPAN) that is using directional antennas to transmit towards a ceiling with an antenna pattern specifically designed to control the interference level.

10. The machine-accessible medium of claim 9, further comprising said instructions causing said machine to perform operations further comprising operating said transceiver in the a millimeter (mm) Wave frequency.

11. The machine-accessible medium of claim 9, wherein said antenna pattern is configured for a signal to be reflected off said ceiling and cover a required area of the given WPAN and reduce interference significantly for adjacent WPANs.

12. The machine-accessible medium of claim 9, wherein said antenna pattern reduces inter-symbol interference (ISI) to enable a simplified baseband implementation to reduce equalization complexity and coding complexity.

13. 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 adapted to point 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.

14. The system of claim 13, wherein said plurality of transceivers are a millimeter (mm) Wave transceiver and said horizontal surface is a ceiling.

15. The system of claim 13, 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.

16. The system of claim 15, wherein said signal pattern enables a simplified baseband implementation to reduce equalization complexity and coding complexity.
