In versions before LCOS 10.30, the current WLAN transmission power could be reduced by a fixed, configured value. This made it possible to adapt the WLAN cell size to the requirements of any particular scenario. This method reaches its limits in the case of a professional WLAN where a value has been set for the actual maximum wireless transmission power and, at the same time, clients should automatically change between the channels of the different 5-GHz subbands. For example, higher transmission powers are permitted in the 5-GHz subband 2 than in subband 1. The fixed reduction in transmission power would be applied to the higher transmission power in subband 2 and also to the lower transmission power permitted in subband 1. This would result in cells of different sizes, depending on the subband selected. As of LCOS 10.30, the actual maximum transmission power can be set as an absolute value, which means that the cell size is always the same, irrespective of the maximum permitted transmission power.
Configure this in LANconfig under using the fields Power setting and Tx Power.
The Automatic mode describes the previous behavior, whereas Manual allows an absolute value in dBm to be specified in the field Tx power.
