Water officials change frequency 

Far-flung city officials responsible for San Francisco’s water supply and its municipal power can communicate over new radio frequencies following a $1.1 million project.

The microwave and two-way radio systems used by officials based near the Hetch Hetchy Reservoir, which is in Yosemite National Park, had to be changed after the frequencies they used were set aside by the federal government for emerging technologies called Advanced Wireless Services.

T-Mobile purchased the frequencies used by the officials and warned San Francisco that its operational communications could be affected unless it changed to new frequencies.

T-Mobile charged San Francisco $1,145,000 to install equipment needed to switch to the new frequencies, San Francisco Public Utilities Commission documents show.
