Yealink W52P is a wireless VoIP DECT system consisting of a base station and a phone handset. The system can be expanded with up to five additional handsets (Yealink W52H), each capable of having its own SIP account. Like other VoIP DECT systems, Yealink W52P allows operation within a range of up to 50 meters indoors and up to 300 meters in open spaces from the base. The Yealink W52P base station can be connected using PoE and does not require additional power.
