Offload 802.11 scanning to low power device

In this generation, Wi-Fi throughput is increasing day by day, with the speed of Wi-Fi data also increasing exponentially. From full HD, 2K to 4K, and 8K video watching standards are improving very fast for users. Users want to roam without any impact on user browsing. The challenge is to backward scan without interrupting the existing connection during roaming. This paper focuses on a low power external device specially designed for scanning purposes. An external Wi-Fi radio is introduced to make scanning faster and improve power saving during the connection process.
