An information distributor (1-3) comprises a processor (422), a network receiver (104) connected to the processor, a transceiver system (105) connected to the processor, and a memory (412) connected to the processor. The memory includes network receiver communication stacks configured to direct the network receiver (104) to wirelessly receive information from a system communication network (111) and transceiver protocol stacks configured to direct the transceiver system (105) to wirelessly transmit the information on demand to a portable computing device located within transmission range of the transceiver system (105). The transceiver protocol stacks include a first module configured to direct the transceiver system (105) to generate a beacon (112), a second module configured to direct the transceiver system (105) to detect an acknoledgement signal generated, in response to the beacon (112), by the portable computing device, and a third module configured to direct the transceiver system (105) to generate, in response to acknoledgement signal, a broadcast (118) incorporating the information. |
