The GeoWave protocol is a wireless communication protocol for devices requiring low power and low bandwidth such as home automation and sensor networks. Jiwave communication using the Jiwave protocol has a 900MHz frequency band, a transmission speed of 10kbps ~ 40kbps, and uses wireless mesh technology supporting bidirectional communication.

Conventionally, there have been developed devices that communicate within a home or a building using Zigbee communication using a 2.4 GHz ISM band, which can be used without approval. However, these devices are used for communication of other devices using Wi-Fi and Bluetooth communication in the same frequency band . &Lt; / RTI >

In this case, since Zigbee communication transmits data with a relatively small power intensity as compared with Wi-Fi communication, there is a problem that a Zigbee communication signal can not be identified when a collision occurs.

Accordingly, the moon pad 100 according to the embodiment of the present invention connects to the integrated access point 200 through the geo-wave communication module 110 and communicates with the integrated access point 200 to allow the user accessing the integrated access point 200 using the Wi- The occurrence of interference with the terminal 300 can be prevented.
