I need to estimate the coverage of a system using the AP1231G and some cisco ip 7920 phones, but i just can't find the receiver sensitivities for the 7920 phone for each of the available data rates: could anyone help me?

Thank you very much

Most 802.11 radios have a receiver sensitivity value of -94 dBm to -85 dBm at a data rate of 1 Mbps (the lower the dBm value, the better the radio's receiver sensitivity). Radio receiver sensitivity changes with data rates; for example, an access point radio might have a receiver sensitivity of -94 dBm at 1 Mbps, but the radio sensitivity might be -84 dBm at 11 Mbps."
