ØÆSØ Say it, say 'ENCRYPTION'
I've seen system maps, estimated and 'tested' coverage...that are nothing like 'real' coverage.. Areas that were supposed to be covered well into the next county that weren't even covered in open water river that separated the counties...
I know of multiple instances where trunked systems 'went live', then immediately ordered to go back to 'the old channels', because coverage was so horrible...Systems that were using 100W mobiles on VHF added zero sites and went to P25 conv on their existing infrastructure using new 50W mobiles and didn't understand why they couldn't hit towers anymore.. Systems with 95% portable coverage using 6W
VHF portables, add a handful of 800 sites, give them a 3w portable, then wonder why their radio keeps beeping and showing 'out of range' in wooded areas that worked perfectly before.. The same wooded areas that comprise a good 35% of the county.
When these upgrades happen, I usually try to talk to the beat cops and the brass,to get their opinions, and they tell me they went with the system because motorola said they had to because of FCC requirements aka narrowbanding (not true) or that the radios were 'digital so no one could hear them'....Sorry, P25 IMBE vocoding is not encryption....nor is 2 slot TDMA..
I get it, but everyone is quick to blame the vendor, when they may have supplied EXACTLY what the purchaser asked for, in a lot of cases, is not what the field level folks expect.
Everyone loves to hate on Motorola and Harris when the new system does not perform the way they expect it to, even if it is built exactly to specs.
Like EMS management in Alberta deploying only portables on a system engineered for mobile on highway coverage, then the people using the system are complaining that portables don't work everywhere or their portables are 'always losing reception' Duh!
