ABSTRACT:
A method, device and system for radio based short range communication makes possible local network access for capacity-demanding broadband services in a cellular short range system such as DECT. Two separate cellular systems for short range communication are integrated to make a hybrid system, where one of the systems is a DECT system and the other system is a LMDS system. The integration combines DECT and LMDS so that LMDS is used for radio transmission between a DECT-PP and a DECT-RFP via an uplink and a downlink, and for transmission of broadband information in a downlink. The DECT aspect is used for speech, narrow band and medium band data communication, and for transmission of authorization/encryption information so that only authorized subscriber can utilize the information which is transmitted via DECT and LMDS.
