Received Channel Power Indicator (RCPI)

A power measurement introduced in802.11k; calculated as an average of all received chains during the reception of the data portion of the transmission.

Introduced in 802.11k, a power measurement calculated as INT((dBm + 110) * 2). Expected accuracy is +/‐ 5 dB. Ranges from 0‐220 are available with 0 equaling or less than ‐110 dBm and 220 equaling or greater than 0 dBm. The value is calculated as an average of all received chains during the reception of the data portion of the transmission. All PHYs support RCPI and, though 802.11ac does not explicitly list its formulation, it references the 802.11n specification for calculation procedures.
