A method comprising: calculating, by a network element or a network operator of a wireless network, when predetermined conditions are satisfied, a Received Signal Strength Indicator (RSSI) level for a reference access point in the network, wherein the network includes a first immediate access point and a wireless client connected to the reference access point; calculating, by a network element or a network operator of a wireless network, an Equivalent Isotropic Radiated Power (EIRP) of the reference access point such that the wireless client measures the calculated RSSI level when the wireless client is within range of the first immediate access point, the method characterized in that calculating the EIRP is based on a measured path-loss between the reference access point and the first immediate access point and on measuring a high Modulation and Coding Scheme zone of the reference access point and a sticky zone of the first immediate access point, the sticky zone comprising an area where the signal from the first immediate access point at the wireless client is at a higher RSSI level than a roaming level while the wireless client remains connected to the reference access point, wherein the predetermined conditions are satisfied when: the wireless client is within a high MCS zone of the reference access point within the network, wherein a high MCS comprises MCS7, MCS8 or MCS9 and/or a zone where the measured RSSI threshold at the wireless client is greater than or equal to -67dBm and the wireless client has roamed to the first immediate access point but has not come within range of a second immediate access point. calculating, by a network element or a network operator of a wireless network, when predetermined conditions are satisfied, a Received Signal Strength Indicator (RSSI) level for a reference access point in the network, wherein the network includes a first immediate access point and a wireless client connected to the reference access point; calculating, by a network element or a network operator of a wireless network, an Equivalent Isotropic Radiated Power (EIRP) of the reference access point such that the wireless client measures the calculated RSSI level when the wireless client is within range of the first immediate access point, the method characterized in that calculating the EIRP is based on a measured path-loss between the reference access point and the first immediate access point and on measuring a high Modulation and Coding Scheme zone of the reference access point and a sticky zone of the first immediate access point, the sticky zone comprising an area where the signal from the first immediate access point at the wireless client is at a higher RSSI level than a roaming level while the wireless client remains connected to the reference access point, wherein the predetermined conditions are satisfied when: the wireless client is within a high MCS zone of the reference access point within the network, wherein a high MCS comprises MCS7, MCS8 or MCS9 and/or a zone where the measured RSSI threshold at the wireless client is greater than or equal to -67dBm and the wireless client has roamed to the first immediate access point but has not come within range of a second immediate access point. the wireless client is within a high MCS zone of the reference access point within the network, wherein a high MCS comprises MCS7, MCS8 or MCS9 and/or a zone where the measured RSSI threshold at the wireless client is greater than or equal to -67dBm and the wireless client has roamed to the first immediate access point but has not come within range of a second immediate access point.
