ISM stands for "Industrial, Scientific, and Medical." The ISM frequencies are typically used for purposes such as wireless communications, scientific research, and medical equipment like MRI (Magnetic Resonance Imaging) machines.
ISM common frequency bands include:
315 MHz Band
433 MHz Band
900 MHz Band
2.4 GHz Band (2.400 – 2.483 GHz)
5.8 GHz Band (5.725 – 5.875 GHz)
Zigbee is a wireless communication protocol designed for low-power, low-data-rate, and short-range wireless networking. It's primarily used in applications involving home automation, industrial automation, and the Internet of Things (IoT).
Zigbee common frequency bands include:
868 MHz in Europe
915 MHz in North America.
2.4 GHz (2.4000 GHz to 2.4835 GHz) in global.
LoRa, which stands for "Long Range," is a low-power, wide-area networking (LPWAN) technology designed for long-range wireless communication. LoRa is commonly used in various IoT applications, including smart agriculture, asset tracking, environmental monitoring, smart cities, and industrial automation, where long-range, low-power communication is essential.
LoRa common frequency bands include:
