A broad range of wireless communication standards emerges to cater the diverse applications. Wireless networks, the IEEE 802.11ah named Wi-Fi HaLow and the IEEE 802.15.4g named Wi-SUN, are commonly used standards among Internet of Things (IoT) and machine-to-machine (M2M) applications. The Wi-Fi HaLow standard is designed for operations at Sub-1 GHz (S1G) band, and is a low power standard developed for outdoor IoT applications. The Wi-SUN standard is designed for wireless smart utility networks (Wi-SUN) to operate at Sub-1 GHz (S1G) band and 2.4 GHz band, and includes frequency spectra (band) shared with the Wi-Fi HaLow standard. Wi-SUN is one example of LR-WPAN. There can be tens of thousands 802.11ah and 802.15.4g devices co-located in the neighborhood. As the IEEE 802.15.4g standard was designed for only allowing coexistence with the other 802.15.4g devices prior to designing the IEEE 802.11ah standard, the 802.11ah network could cause severe interference with the 802.15.4g network.
Accordingly, it is desirable to provide a new coexistence control system and a method for co-locating the 802.11ah network and the 802.15.4g network in an area.
