  • Patent number: 7817958
    Abstract: The present invention is a system for and a method of providing one or more remote coverage areas for wireless communications. In an embodiment, a system for providing a remote coverage area for wireless communications comprises a local system that generates a first radio communication signal and a remote system located geographically remote from the local system. The remote system comprises a first converter that converts the first radio communication signal to a stream of data packets, a network that receives the stream of data packets from the first converter; and a second converter that receives the stream of data packets from the network and generates the remote coverage area by converting the stream of data packets to a second radio communication signal. The remote coverage area may be located indoors.

  • Patent number: 5850609
    Abstract: At least one fixed beacon is associated with a user of a mobile station and emits, with a range (r) substantially smaller than the characteristic dimension (R) of a cell, a radio signal specific to said user. When the mobile station detects the radio signal emitted by the beacon, the station addresses a signal to the communication network indicating that it is within range of the beacon.
