trouble with GSM not relaible enough in an emergency,same as TETRA,it
requires too many aerial sites for a start.

the current police radio system does the job it is supposed to do in most
areas,ok not secure,but secure is only really needed by certain users.

ie special branch/firearms/cid a normal officer does not need secure radio.

GSM yes the power companies have been chucking there radio licenses away
over last year or so and going GSM.

what happend in January this year in the bad weather,contact with mobile
electricity board teams was lost but only in the areas where they had
switched to GSM,those still using MP1327 trunk net,comms were ok.

we had no power for some time,the lady at there control,had no idea who was
out working or where they were,she said there mobile phone network had been
knocked out by the bad weather in some areas.

you can use both systems,any pnc check should be done by mobile phone,but
for regular policing then just normal radio.

but make sure all specialist teams are secure

its a joke that in the UK special branch and royalty protection are using
analogue comms on freq they have used for years.
