Systems and methods of coexistence of Wi-Fi communication and narrowband communication
Disclosed herein are related to a co-existence of wireless communications over different protocols. In one aspect, two devices may communicate with each other through a wireless link. The two devices may communicate latency sensitive data (e.g., artificial reality data) through one or more frequency bands, according to a first wireless communication protocol. Meanwhile, another device in the vicinity may communicate or attempt to communicate through a portion of the one or more frequency bands, according to a second wireless communication protocol. In one aspect, a frequency band, transmission power, and/or duty cycle of transmission of the another device for communication over the second communication protocol and can set or controlled, to avoid interfering with the communication over the first communication protocol.

determining, by a wireless device, at least one frequency band within which to perform frequency hopping, the at least one frequency band comprising at least one of: an upper contiguous portion within a predetermined frequency range, or a plurality of frequency bands spaced apart from each other at a defined interval and each having a defined bandwidth, the defined interval being a channel bandwidth of communication through a first protocol and each frequency bandwidth of the plurality of frequency bands being a channel bandwidth of communication through a second protocol; and
performing, by the wireless device, frequency hopping within the at least one frequency band.
2. The method of claim 1 , wherein a transmission output power of the frequency hopping by the wireless device is less than or equal to 10 dBm/MHz.

setting, by the wireless device, channel occupancy time (COT) to be equal to or less than a dwell time.
10. The method of claim 9 , wherein COT is a time period for the wireless device to evaluate a channel for the frequency hopping, and the dwell time is a time period that the wireless device can stay in the same channel for frequency hopping.
11. The method of claim 1 , further comprising:
setting, by the wireless device, an allowable transmission power for the frequency hopping, according to a bandwidth of the at least one frequency band.
12. A wireless device comprising:
