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

Claim 19:
20. The apparatus of claim 17, wherein the controller 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 based on 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 apparatus of a transmission event from the given wireless client device, RSSI(shield) is an aggregate RSSI at the apparatus 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.
