The 900 MHz band is also known as the 33-centimeter band and ranges from 902 to 928 MHz. It is license-free in large parts of the world: all of ITU’s region 2 (23 countries in Americas) and some additional countries like China, Australia, New Zealand and South Korea. In the USA, like WiFi, FCC Part 15 certified radios are permitted for unlicensed operation.
RF signals at 900 MHz can penetrate through building walls, vegetation, and other obstacles. 900 MHz signals can also go around objects by refraction. Due to these transmission characteristics, broadband communication in the 900 MHz band achieves a good balance of range, penetration, and throughput. A private wireless broadband network implemented in a license-free band avoids the recurring monthly cost of public cellular network.
The Smart Radios are available in 3 different categories to meet various project requirements and budgets. Below table provides quick overview of technical specifications. For more information download the detailed datasheet.
