Assignee: CISCO TECHNOLOGY, INC.
Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 9:
10. The system of claim 9, wherein the serving wireless access point is configured to compute the transmit power as a function of data rate, power(client, data_rate) to be used for transmissions to or from the given wireless client device using a computation:

power(client,data_rate)=RSSI(shield)−RSSI(client)+decodingMargin_dB(data_rate)+power_max+steering_gainDb,

where RSSI(client) is received signal strength information associated with reception at the serving wireless access point of a transmission event from the given wireless client device, RSSI(shield) is an aggregate RSSI at the serving wireless access point of all shield wireless transceiver devices that would participate in the transmission event, decodingMarginDb(data_rate) is a signal-to-noise ratio (SNR) to decode a packet at the data rate, power_max is a maximum power to be sent per stream, and steering_gainDb is a beamforming/nulling gain.
