Abstract: In one embodiment, a system comprises a master unit having communication ports and coupled to one or more base stations, and a second unit coupled to the master unit. The second unit has a communication port coupled to one of the communication ports of the master unit via a communication medium and communicates Ethernet and digitized RF data using the communication port. The second unit requests an IP address from the master unit. The master unit determines which communication port of the master unit received the request and assigns an IP address to the second unit based on which of the communication ports received the request. The master unit sends the IP address to the second unit, wherein the second unit is configured for operation using the IP address.

Abstract: In one embodiment, a system comprises a master unit having communication ports and coupled to one or more base stations, and a second unit coupled to and located remotely from the master unit. The second unit has a communication port coupled to one of the communication ports of the master unit via a communication medium and communicates Ethernet and digitized RF data using the communication port. The second unit requests an IP address from the master unit, and the request includes a MAC address of the second unit. The master unit determines which communication port of the master unit received the request and assigns an IP address to the second unit based on which of the communication ports received the request and without using a DHCP server. The master unit sends the IP address to the second unit, wherein the second unit is configured for operation using the IP address.

Abstract: An improved private radio communication system and method for routing data signals to multiple remote devices connected to a common remote receiver and for routing data signals to applications both within the remote devices and within the common remote receiver is disclosed.

Abstract: A radio communication system having a host computer and at least one remote, mobile, two-way radio communicating with the host computer by exchanging data packets. A communication gateway between the host computer and the remote radios mediates the exchange and maintains an address table containing both the physical address and an internet address for the various components. The gateway translates between the physical and internet addresses, allowing more flexible communication between the various interconnected components.

Abstract: In a trunked radio data communications system using half-duplex radios, plural data messages are exchanged over a single RF working channel using a technique where a working channel repeater assigned to a data call sends status messages to both the data originating radio and the data receiving radio indicating which radio is currently enabled to transmit a data message over the working channel. Each time the currently enabled radio sends a data message to the working channel repeater, the repeater changes the status message so that the other radio can respond. As a result, data messages can be efficiently and reliably exchanged over the same working channel without collision or having to request and set up a new working channel for each data message.
