Servicing over a million end-users in an approximately 2900 square mile area, Salt River Project is one of the USA’s largest public power utilities. In addition to electricity, SRP also delivers over 800,000 acre-feet of water to customers annually.

Key challenges

Having acquired 2 MHz of spectrum in the 700 MHz Upper A Block in 2015, SRP required a partner to provide the communications infrastructure for a new 1300 square mile Field Area Network (FAN).

Encompassing three Arizona counties, including the metropolitan Phoenix area, the FAN is required to enable centralized monitoring and control of SRP’s distributed power and water systems. SRP’s new FAN will also be used to monitor and control power flows into and out of the grid from numerous advanced solar installations.

With spectrum being both scarce and valuable, the biggest challenge was to find a solutions provider who could optimize data throughput in the narrowband channel SRP had available.



Mimomax Tornado Radio (Tier I) and Mimomax Pyxis Radio (Tier II) in a Multi-Tier Field Area Network (FAN).

Key features: up to 1280 kb/s data rate in 50KHz at Tier I level, sophisticated data compression techniques plus frequency re-use at Tier II level.

Application: SCADA, Distribution Automation, Advanced Meter Infrastructure.
