MAS Frequency Coordination
Multiple Address (MAS) systems provide the capability to communicate between a central location and multiple remote locations in a two-way or one-way configuration. Multiple address is heavily used for control and monitoring of distribution networks for electric, natural gas, petroleum and water as well as switches and signals along railroad tracks. Other uses are automatic meter reading by electric, gas and water utilities for fast efficient collection of consumption data. The multiple address authorized frequency bands are:
| 928.000 MHz to 928.850 MHz/ 952.000 MHz to 952.850 MHz |
Paired frequencies |
| 932.250 MHz to 932.500 MHz/ 941.250 MHz to 941.500 MHz |
Paired frequencies |
| 956.250 MHz to 956.450 MHz | Unpaired frequencies |
The standard channel bandwidth is 12.5 KHz but wider bandwiths are possible. With some limitations, fixed and mobile systems are permitted. Licenses are granted on a site-by-site basis and are ensured a clear non-interference operating frequency.
Frequency coordination for one system, including:
- Frequency selection per FCC 101.105
- Coordination with Canada for systems operating close to the US-Canada border
- Application preparation
