ABSTRACT:
An information distributor comprises a processor, a network receiver connected to the processor, a transceiver system connected to the processor, and a memory connected to the processor. The memory includes network receiver communication stacks configured to direct the network receiver to wirelessly receive information from a system communication network and transceiver protocol stacks configured to direct the transceiver system to wirelessly transmit the information on demand to a portable computing device located within transmission range of the transceiver system. The transceiver protocol stacks include a first module configured to direct the transceiver system to generate a beacon, a second module configured to direct the transceiver system to detect an acknowledgement signal generated, in response to the beacon, by the portable computing device, and a third module configured to direct the transceiver system to generate, in response to the acknowledgement signal, a broadcast incorporating the information.
