Abstract

Claims (31)

1. A wireless access point (WAP) apparatus supporting wireless communications with associated stations on a selected communication channel of a wireless local area network (WLAN); and the WAP apparatus comprising:

a plurality of shared and discrete components coupled to one another to form a plurality of transmit and receive chains each coupled to a corresponding one of the plurality of RF communication ports for orthogonal frequency division multiplexed (OFDM) multiple-input multiple-output (MIMO) WLAN communications with the associated stations;

the plurality of radio frequency “RF” communication ports each configured to mechanically couple to any one of: a coaxial cable direct connected to one of the associated stations, a coaxial cable direct connected to a remote antenna, and an antenna; to allow on premises installation of the WAP apparatus with a customized mix of wired and wireless communication medium coupled to the plurality of RF communication ports;

a port evaluator coupled to each of the plurality of RF communication ports to evaluate the selected communication channel on each of the RF communication ports with respect to each of the associated stations; and

a port correlator coupled to the plurality of components and the port evaluator and configured to correlate each of the associated stations with a corresponding subset of the RF communication ports supporting optimal communications therewith based on the evaluation by the port evaluator.

2. The WAP apparatus of claim 1 , further comprising:

the port correlator further configured to dynamically manage power on the RF communication ports during each downlink to a corresponding one of the associated stations by reducing power on RF communication ports which do not support communications with the corresponding one of the associated stations during downlink communications therewith.

the port correlator responsive to the evaluation of the communication channel on each RF communication port by the port evaluator to identify a type of communication medium coupled to each RF communication port as one of a wired type and a wireless type and to set a power level for an RF communication port direct coupled to an associated one of the stations via a coaxial cable, independently of the power levels for remaining ones of the RF communication ports coupled to corresponding antenna.

4. A wireless transceiver apparatus for a wireless local area network (WLAN), supporting multiple-input multiple-output (MIMO) wireless communications between associated transceiver nodes on a selected one of a plurality of communication channels; and the transceiver apparatus comprising:

a plurality of radio frequency “RF” communication ports configured to couple to at least one of a wired and a wireless communication medium;

a plurality of shared and discrete components coupled to one another to form transmit and receive chains each coupled to a corresponding one of the plurality of RF communication ports for orthogonal frequency division multiplexed (OFDM) multiple-input multiple-output (MIMO) WLAN communications with the plurality of associated transceiver nodes;

providing a plurality of shared and discrete components coupled to one another to form a plurality of transmit and receive chains each coupled to a corresponding one of a plurality of RF communication ports for orthogonal frequency division multiplexed (OFDM) multiple-input multiple-output (MIMO) WLAN communications with the associated stations;

providing a plurality of radio frequency “RF” communication ports configured to mechanically couple to any one of: a coaxial cable direct connected to one of the associated stations, a coaxial cable direct connected to a remote antenna, and an antenna; to allow on premises installation of the WAP apparatus with a customized mix of wired and wireless communication medium coupled to the plurality of RF communication ports;

evaluating the selected communication channel on each of the RF communication ports with respect to each of the stations; and

correlating each of the associated stations with a corresponding subset of the RF communication ports supporting optimal communications therewith based on the evaluating act.

6. The method for operating a WAP of claim 5 , wherein the correlating act further comprises:
