The 433.92 MHz frequency is part of the ISM (Industrial, Scientific, and Medical) band commonly used for remote controls, wireless sensors, garage door openers, smart home devices, and low-power communications. It offers longer range and better penetration through walls compared to higher frequencies, making it ideal for simple data transmissions. However, it provides slower data rates and is more prone to interference in regions where it is widely used. In contrast, 2.4 GHz supports higher bandwidth and faster speeds, but with shorter range and more congestion.
