Abstract: An intermediate unicast network is provided for use in a multicast data network where the multicast network is a local server and a plurality of network hosts, which may be, for example, point-of-sale registers. The intermediate network includes a network device for receiving multicast data from the local server, encapsulating such data in a unicast data transfer frame, and transferring the unicast data to a plurality of dongles, each of which being associated with a corresponding network host. Each dongle is configured to decapsulate the unicast data received from the network appliance and to re-assemble the data into multicast data for transfer to the associated network host.

Abstract: An appliance for transmitting and receiving encrypted wireless network signals, preferably, in a 900 MHz band, includes a radio frequency module, coupled to a cryptographic module, which, in turn is coupled to an Ethernet interface module and a power-over-Ethernet splitter. The components are affixed to a thermally conductive substrate that is mounted to the floor of a chamber defined by a thermally conductive housing.
