Abstract

A wireless communication device for mitigating interference in a wireless communication network and a method of operating the same are provided. Generally, a method includes sensing, with a wireless communication device, pulses of electromagnetic radiation that occur repeatedly within a frequency band used by the device for communication of signals; identifying the pulse as interference; and determining a plurality of frequencies of interference within a frequency band used by the wireless communication device. Next, when one of the repeating pulses is sensed, the sensitivity of the wireless communication device is reduced at a frequency corresponding to the frequency of the interference. Thus, the spectrum of electromagnetic radiation around the wireless communication device is perceived by the device as being free of interference, thereby enabling it to be transmitted and / or received more frequently. Other embodiments are also disclosed.

Description

[0001] Cross References to Related Applications [0002] This application is an international application of U.S. Patent Application No. 16 / 721,051, filed December 19, 2019, which claims the benefit under Section 119e of the U.S. Patent Act to the U.S. Provisional The benefit of priority of patent application Serial No. 62 / 877,946, both of which are incorporated herein by reference in their entirety. technical field [0003] The present disclosure relates generally to wireless communication systems, and more particularly, to wireless devices, systems, and methods of operation for minimizing or eliminating the effects of interference when wireless devices and interfering devices coexist or are co-located in a wireless network. Background technique [0004] The proliferation of Internet of Things (IoT) devices in the smart home and enterprise has led to greater adoption of wireless networking technologies, for example, in access points (APs), wireless or Bluetooth (BT) speaker...
