Patent number: 10257236Abstract: 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.Type: GrantFiled: May 24, 2018Date of Patent: April 9, 2019Assignee: NETGEAR, INC.Inventors: Joseph Amalan Arul Emmanuel, Peiman Amini

Patent number: 10237834Abstract: Systems and methods for controlling the transmit power and the receive sensitivity of an access point for achieving symmetric link balancing is described. When an access point operates with symmetric link performance, the access point does not inefficiently use available bandwidth for transmitting or re-transmitting to a client station that cannot communicate with the access point. Moreover, the access point does not back off transmissions due to activity of neighboring basic service sets when not needed. The receive sensitivity can be controlled using a hardware attenuator or software commands that adjust a programmable gain in a wireless local area network chipset used by the access point, or it can be controlled using adjustable levels in the software for processing or responding to packets.Type: GrantFiled: June 8, 2018Date of Patent: March 19, 2019Assignee: NETGEAR, INC.Inventors: Joseph Amalan Arul Emmanuel, Peiman Amini
