The 315 MHz frequency is part of the UHF (Ultra High Frequency) band and is widely used for low-power, short-range wireless communication in the Americas and parts of Asia. Known for its excellent penetration and low interference potential, 315 MHz is a cornerstone of keyless entry systems, remote controls, and unlicensed IoT applications. It is especially favored…

The 145 MHz frequency sits within the 2-meter VHF band, one of the most widely used and versatile bands in the radio spectrum. While globally allocated for amateur radio (ham radio) in most regions, its adjacent frequencies are also used for land mobile, public safety, and aeronautical telemetry. This band is known for its excellent propagation…

The 2450 MHz or 2.45 GHz frequency sits at the heart of the 2.4 GHz ISM band—one of the most universally recognized and widely utilized sections of the radio spectrum. It plays a critical role in modern wireless communication, serving technologies from Wi-Fi to Bluetooth, Zigbee, and industrial automation. Unlicensed yet globally harmonized, 2450 MHz exemplifies spectrum efficiency…

The 169 MHz frequency is a part of the VHF spectrum, situated just above traditional land mobile and amateur allocations. Once used primarily for pager systems in Europe, it has evolved into a powerful niche for low-power, wide-area (LPWA) communications, especially in smart metering, utility monitoring, and IoT applications. Though limited in bandwidth, the 169 MHz band…
