The above chart shows the current radio system in use by the police and fire departments of the cities. An explanation of the terms and technology:

VHF: Very High Frequency--frequencies found between 150 and 174 MHz, used for public safety communications.

UHF: Ultra High Frequency--frequencies found between 450 and 470 MHz, used for public safety communications.

UHF-T: frequencies used for public safety communications between 470 MHz and 512 MHz; this "band" of frequency spectrum was opened to public safety communications in large metropolitan areas due to high demand for bandwidth. The T stands for television, which is what the frequencies are used for in other areas of the United States.

800 MHz Trunked: the newest band for public safety communications; frequencies range from 851 MHz to 869 MHz. On "trunked" systems, one user of a radio switches between multiple frequencies; this makes for more efficient allocation of spectrum.

800 MHz Trunked Digital: same as 800 MHz trunked, except that the radio transmissions are sent digitally. This provides for enhanced clarity and security. Most radio transmissions today are analog, not digital.
