. A DECT phone must remain in proximity to its own base (or repeaters thereof), and WLAN devices have a better range given sufficient access points, however voice over WLAN handsets impose significant design and maintenance complexity for large networks to ensure roaming facilities and high quality-of-service. There are some of the traditional telephone equipment manufacturers and smaller enterprises that offer IP-DECT systems, both for residential (single-cell base station/access points), as well as for enterprise usage (multi-cell with multiple base stations/access points, and/or seamless handoff between cells) where it is important to cover large areas with a maintained speech path.
