Abstract
Disclosed herein is an apparatus and method for low power local area communication using event signal control. The low power local area communication apparatus includes at least one coordinator and a plurality of network device. The network coordinator transmits a periodic beacon signal based on the preset beacon period of a superframe and a continuous RF event signal, receives a first signal including a Service Set Identifier (SSID) and a second signal including the SSID and an event detection code, and performs the transmission or reception of data when authentication has been completed. Each of the network devices generates and transmits the first and second signals, performs the transmission and reception of data after authentication has been completed, and is thereafter switched to power saving mode or OFF mode. Accordingly, the construction of the system is simplified, and the cost of the system is reduced.
