Tetra will not reach Limerick until 2010

I suspect that the Tetra which is currently used by the Gardai in Dublin is not itself prone to hacking. I suspect that Gardai Control in Harcourt is both broadcasting on both Analogue and Tetra. This would give the appearance that Tetra can be scanned by normal analogue VHF radio.

Most probable, would just be nice if people could admit they made that mistake

Well I just thought the social deviants wouldn't have Long Wave buttons on their bitchin sound systems.

to the best of my knowledge tetra can be hacked with an off air decoder im not sure of the full workings of this system but it requires some serious cash to buy the equipment and a high spec laptop even then i believe the system wont hack unless your on the transmitting site connected to the correct equipment, near impossible, ive monitored tetra signals from northen ireland and it sounds like very harsh static with data running through it, most scanner users etc wouldnt be bothered to invest money in that kind of system, also i believe the luas is using some form of trunked network with an encryption protocal which at times can broadcast the control in the clear but not the luas itself its user selectable, also the psni had the best radio system called masc it required every radio to have a unique id similar to a mac address on a pc and if an unknown id logged onto system such as off duty member taking radio home or some clever person hacking system the radio can be shut down and never re-used on the network with out some serious know how, and onair code changing was possible, so if a scanner logged onto the network it cant be shut off the network but all the legal radios on network would be assigned a new code locking scanner user out of the network.

An old friend of mine whose ex-ruc told me that in the north in the 80's they had an encrypted radio system they worked off and it was pretty good, state of the art stuff, way ahead of its time.

The provos etc... could scan the frequency and listen in all right but all they got was a bunch of garbled noises and squelches. Sooooo... they recorded some of the communications on tape and went down to Dublin port and met up with corrupt russian kgb heads in the harbour who visited from time to time and gave them some of the tapes - russian heads brought them back to the thier ships and decoded them using thier sophisticated cold war radio equipment, for nice price.

i think that is the only way around tetra off air decoding if you know what your at could be done with very little time delay but expensive and would really need to be justified i believe the gardai are wise enough to use phones for such comms only way around it would be to steal a radio and then give it 24hrs and encryption keys could be changed

for nice price:D

I bet the Chuckies did some serious damage with those orders for the takeaway!

They are well equiped on all fronts anyway. This system is in the MET already I believe and our Tetra system will be personal issue radio with tracking and all the other stuff your speaking about.

The trial Tetra already has these security features but not the personal issue or tracking part. (My locker now has wires sticking out of it like a bad DIY job

)

What Karlito says is spot on.

We use 'Airwave' radio, which is a tetra system in the UK. Its a good system that's now been rolled out on the London Underground as well, meaning we now have full subterranean comms, which was an issue during 7/7, though the Transport Police had a limited system in place at the time.

As regards network security, handsets are individually ID'd, so a terminal will be linked to a a serving officer. Unknown users are 'stunned', and this includes stolen handsets, meaning any user not recognised by the system gets booted and the set becomes useless.

As regards network security and hacking.....well I think the fact that some criminals here are offering big money for a functioning airwave terminal speaks volumes about the network's security.

Our handsets also function as mobiles (text messaging etc) and can receive incidents from command and control etc and can be gps enabled.

METMAN have you heard much about the health risks involved ?

metman · 18-11-2008 10:44PM

IR - well I've been using it for 5 years and its done less damage than the alcohol consumption

Seriously? I heard the usual stuff when the system was being rolled out, but its not something I really worry about to be honest. Day to day I'm more worried about getting stabbed/shot/killed by writers cramp, than dying of cancer thanks to my radio....:D

Believe me, Irish Rail, i've used the the aerials on our current radios to check under doors, go through rubbish, check dirty nappies etc...
The amount of times I see members sticking radio aerials into their gobs, we're immune to anything!

I am led to believe that Tetra (Ireland) will be compatible with the Barracuda System used by the emergency services in the North!

Yeah thats the plan. Will help cross border operations especially with the border counties seeing alot of cars taking off and heading for the border.

With the prediction that many members are going to be curious about their home district's activities I'll put 5 euros on a couple of dozen radios being stunned as soon as they're issued!

I'll bet €20. Haha easy money

Once you've been allocated a radio and its assigned to you, it won't matter if you tune into your local channel or anywhere else. I've listened to other boroughs and even forces radio traffic and the system caters for this.

Did somebody mention Limerick ?!?
