WIFI ROAM WITH BAND SWITCH AVOIDANCE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18296193 titled 'WIFI ROAM WITH BAND SWITCH AVOIDANCE

Simplified Explanation

A wireless device can use a 5 GHz frequency band to support both Wi-Fi and Bluetooth. The band is divided into two sub-bands. The device can scan for suitable channels in one sub-band and switch to the other if no suitable channel is found.

• The wireless device supports both Wi-Fi and Bluetooth on the 5 GHz frequency band.
• The band is divided into high and low sub-bands.
• The device scans for suitable channels in the first sub-band.
• If no suitable channel is found, it switches to the second sub-band for scanning.

Key Features and Innovation

• Dual support for Wi-Fi and Bluetooth on the 5 GHz frequency band.
• Division of the band into two sub-bands for efficient channel scanning.
• Roam scan feature to find suitable channels in the first sub-band.
• Band switch protocol to switch to the second sub-band if no suitable channel is found.

Original Abstract Submitted

A wireless device may use a 5 GHz frequency band to support both Wi-Fi and Bluetooth. The 5 GHz frequency band may be divided into two portions (e.g., high sub-band and low sub-band). A Wi-Fi module of the wireless device may perform a roam scan on a first sub-band to determine attempt to find a candidate channel that meets a target criteria. When the candidate channel that meets the target criteria is found on the first sub-band, the Wi-Fi module may join the candidate channel. If no acceptable candidate channel is found, the wireless device may perform a band switch protocol to allow the Wi-Fi module to preform a roam scan on a second sub-band.
