A sensor gateway manages wireless communications to sensors and the exchange of data between the sensors and a connection to the Internet. A sensor gateway processor runs the network and wireless stack, automatically picks the same channel as the home access point (AP), and runs sensor software to provide the sensors with low power, wireless support and deep sleep support. The sensor gateway selects same channel as the home AP by following the strongest beacon or by following the home AP service set identifier (SSID), in case more than one strong beacon is present. If the home AP and sensor gateway are placed close by and are on a different channel in 2.4G, there is destructive interference between the two devices. By using same channel on the sensor gateway as that of the home AP, both devices can coexist in same band without destructive interference.
