The 315 MHz frequency is widely used for wireless remote controls, keyless entry systems, garage door openers, and security devices, particularly in North America and parts of Asia. Operating at a lower frequency than 433 MHz, it provides good range and wall penetration with relatively low power consumption. However, it supports slower data rates, making it ideal for simple command transmissions rather than high-bandwidth applications. The 315 MHz band remains popular for reliable, low-power communication in residential, automotive, and industrial environments.
