In this paper we consider the coverage range of a new system which is based on voice over WLAN (Wireless Local Area Network) and enhance this range using diversity techniques. This new system which has high Quality of Service (QoS) requirements has been developed within the WINDECT (Wireless local Area Network with Integration of Professional-Quality DECT Telephony) project. Increasing coverage range per each Access Point (AP) reduces the number of required APs and as a result the infrastructure cost. Comparison between WINDECT's range and the range of DECT (Digital Enhanced Cordless Telecommunications) will be made and measurements and simulations applying diversity techniques to increase the range will be considered.
