800 MHz doesn't serve the needs of rural communities any better. Rural Sheriff's Departments and volunteer fire departments that are off the main highway are generally not served by these multi-million dollar proprietary systems.
By the way, before closing our comments on the subject of 800 MHz, it is only to fair to point out that digital radios in general have taken a bad rap for voice quality. The fact is that the publicity deals primarily with first generation vocoders (the electronic circuit device that converts analog to digital). A good example is a recent article dealing with problems associated with digital radios at West Point. Regrettably, the article neglected to mention that the radios used were first generation models. Of equal importable, the demonstration involved a fully suited firefighter talking through a face mask. You couldn't understand what was being said with or without the radio!
In the interest of fairness, it should be noted that advanced model vocoders are getting better and better, and will soon surpass the audio quality of analog (as was the case in consumer home entertainment systems). The new Broadcom G722 vocoder chip has an audio range of 50 to 7000 Hz which is significantly better than current analog radio technology.
The bottom line is that all 800 MHz isn't all bad anymore than all digital radios are all bad. The trick is to make sure you are dealing with fact - not fiction!
