Latest Patents

One of his notable patents is titled "Frequency translation to local multi-point distribution system for personal communications services." This invention introduces a system designed to extend the range of Personal Communication Services (PCS) band wireless local loop services. The first embodiment of this invention features a frequency translation unit located at both the user's residence and the central hub. This unit translates the PCS signal from the PCS frequency band to the Local Multipoint Distribution System (LMDS) band and back. The advantage of LMDS is its significant range over DECT and PHS without incurring substantial costs. This frequency translation allows DECT and PHS telephones to operate over greater distances, reducing the need for numerous cellular transceiver sites.

A second embodiment of the invention allows the use of either PCS or known cellular telephones within a user's residence without routing calls through the more expensive cellular network. The frequency translation unit translates from PCS or cellular frequencies to LMDS frequencies, enabling calls to be completed over the more economical LMDS network. Outside the user's residence, the PCS or cellular telephone functions as usual.
