Sensor gateway
First Claim
1. A method for managing wireless communications between a plurality of sensors and a backend connection, comprising:
- providing a sensor gateway in wireless communication with said sensors within a communications band over a first channel of a plurality of channels, said sensor gateway exchanging information between said sensors and said backend connection via a home access point (AP) or gateway, said AP or gateway engaging in wireless communications within said communications band over a selected channel of the plurality of channels; and
said sensor gateway automatically determining a characteristic of a beacon frame and switching from the first channel to said selected channel when the characteristic of the beacon frame indicates that communication via said selected channel will be improved relative to communications via the first channel, causing said sensor gateway to communicate via a same channel as said AP or gateway and facilitating reduced communication interference between said sensor gateway and said AP or gateway, said same channel being said selected channel.

Abstract
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.
