WiFi HaLow For IP Cameras Examined
Using WiFi for IP cameras is widely viewed negatively due to limited transmission range and problems working through walls. However, the WiFi Alliance has standardized "HaLow" aiming to solve those problems.
In this report, based on our research and feedback from Wi-Fi Alliance and Newracom (a US company developing HaLow chips), we examine what Wi-Fi HaLow is, how it differs from existing Wi-Fi generations, the adoption of Wi-Fi HaLow, how Matter standard will affect HaLow, etc.
