In the very near future, personal communications systems such as the CT-2 system going into service in the U.K. and the DECT system under development in Europe will be wide spread. As these and similar systems become available, personal wmmunications devices such as cordless phones will be carried at all times. The same unit will serve as your cordless phone at home, business cordless phone at work, and will provide access to a network of telepoint units (wireless phone booths) elsewhere. It may even serve as a wireless access device communicating with a mobile pro- tocol converter to utilize wide area cellular systems. In this context and in the residential cordless application, it is possi- ble to integrate the functions of the cordless phone with an alarm system.
