    Abstract: Provided herein are techniques for enabling communications between an access point (AP) and a number of stations (STAs) while maximizing transmission quality and/or minimizing power consumption. For example, an STA may be associated with a camera device used to capture video data and transmit the video data to the AP, and the AP may be configured to receive a registration request from the STA, register the STA, receive video data from the STA, and transmit the video data to a backend system such as a storage server. In some cases, the AP and STAs may communicate using a communication bandwidth that is sub-GHz but has a higher bandwidth relative to the low-bandwidth sub-GHz communication protocols discussed above. An example of such a high-bandwidth sub-GHz communication protocol is one that supports data transmission (e.g., video data transmission) using a bandwidth of 900 megahertz (MHz).
