Systems and methods for a gateway that couples two or more networks are provided. The gateway allows mobile stations with subscriptions in one network to roam and operate in another network. The networks that can be coupled by the gateway include CDMA-based networks, GSM-based networks, iDEN-based network and WiMAX-based networks.

System and method for signaling gateway

A method and system for communicating an ultra-wideband signal carrying a combined digital signal that represents digital signals for multiple communication channels of a wireless communication system. A distributed antenna system includes multiple remote antenna entities. Each remote antenna entity may include an ultra-wideband transceiver for sending or receiving the ultra-wideband signal. The multiple remote antenna entities may be spaced apart within an indoor premises so as to extend cell coverage of a base transceiver station. The ultra-wideband signal may be transmitted in a forward-link direction towards one or more wireless communication devices or in a reverse-link direction towards the base transceiver station. An aggregator within a remote antenna entity may aggregate multiple combined digital signals so as to form an aggregated combined digital signal that may be transmitted in a reverse-link direction towards the base transceiver station.

System and method for indoor wireless service distribution via ultra-wideband signals, and aggregation of combined digital signals for wireless service

A system and method of transmitting and receiving RF service signals between a base transceiver station (BTS) of a wireless communication system and subscriber units within a structure. In the forward link, the system demodulates the RF service signal from a BTS to recover a digital service signal; conditions the digital service signal for transmission via the powerline of a structure; and modulates an RF carrier with the digital service signal to generate the RF service signal for wireless transmission to subscriber units within the structure. In the reverse link, the system demodulates the RF service signal from subscriber unit(s) to generate a digital service signal; conditions the digital service signal for transmission via the powerline; and modulates an RF carrier with the digital service signal to generate the RF service signal for transmission to the BTS. Another embodiment eliminates the modulation of an RF carrier with the digital service signal to generate an RF service and vice-versa at the BTS.

System and method for transmitting wireless digital service signals via power transmission lines

Systems and methods for providing in-building wireless communications are provided. A master base transceiver station can include a standards-compliant powerline modem coupled to one or more slave base transceiver stations and/or antenna modules. A bridge can be provided that includes a standards-compliant powerline modem coupled to one or more base transceiver stations. The standards-compliant powerline modems communicate standards-compliant digital signals over powerlines. The master base transceiver station or bridge is coupled to a mobile switching center/base station controller via a network.

Powerline base station

A signal conditioner (SC) and method for communicating via a shared transport medium (STM) between a BTS and remote antenna entity (RAE). A first SC connects to the BTS and a second SC connects to the RAE. Each SC connects to a cable modem or BPL modem that interfaces to the STM. The first SC receives an RF signal carrying an analog baseband signal (ABS) representing digital signals for multiple communication channels. The first SC generates a CDS based on power level measurements of the ABS, and then transmits the CDS to the second SC via the STM. The second SC recovers the CDS, converts the CDS to another ABS, generates an RF signal carrying the other ABS, and transmits this RF signal to the RAE for transmission away from the RAE. The first SC and second SC also facilitate communication of a CDS from the RAE to BTS.

Systems and methods for communications between networks that support dispatch communication services are provided. A server is coupled to at least two networks that provide dispatch communications, one of which employs an inactivity timer. When the server determines that the inactivity timer for a dispatch call is about to expire due to, for example, no bearer packets being transmitted, the server will request the floor of the call. The server will then transmit bearer packets for a predetermined amount of time, and then release the floor.

System and method for supporting inter-network dispatch calls

A signal conditioner (SC) and method for performing communications via a shared transport medium between a base transceiver station (BTS) and a remote antenna entity (RAE). A first SC is connected to the BTS and a second SC is connected to the RAE. Each SC interfaces to the transport medium. The first SC receives an RF signal representing a combined digital signal (CDS) from the BTS. The first SC recovers and conditions the CDS, and then transmits the conditioned CDS to the second SC via the transport medium. The second SC receives the conditioned CDS, recovers the CDS, produces an RF signal representing the CDS, and transmits this RF signal to the RAE. The RAE sends this RF signal to an antenna of the RAE for transmission of this RF signal via the antenna. First SC and second SC also facilitate communication of a CDS from RAE to BTS.
