How the Police, and the Public, are being mislead about Airwave.
An Insider Evaluation of the Propoganda. ---------------------------------------------------------------- I am posting this in a few choice UK newsgroups who have some interest in the police radio system. If you take offence to this then I apologise, but I think you will find what this post contains interesting. At least I hope you do! Let me be quite clear about a few things first of all. It is the government's fault that police forces have had to switch to Airwave. They have sold off frequencies we have been using for years with no major problems. Do not blame your local police force for buying into duff technology, they had little choice in the matter. And for those of you who might read the items below and say 'purely teething problems', then let me say this: We are something like the 38th Force to go live with Airwave. o2 have had 37 previous installations to make their cock ups and learn by them. Our Force has also been using Airwave (in a testing capacity) for well over a year, and live for 6 months in some areas. NONE of the technical problems raised time and time and time again have been fixed during any of this. Our communication equipment provider for control rooms also appears to be totally inept when it comes to getting the data-display side of things working. The 'last officer calling' function, whereby their callsign and warrant number is displayed in the talk-group button on the system is wiped out and replaced with either a blank space or gibberish the moment the controller transmits. The 'subscriber' screen - a utility on the control system that shows which officers are on a particular talkgroup, also fails to function correctly. Those who are off duty do not 'fall off' the display, meaning that there is around 50 pages of 'subscribers' on any talkgroup, most of them off duty. Very useful! There are hundreds of other minor problems as well, but the discussion of them is not the purpose of this post. It is merely to cut through the propoganda being issued by the Government, O2 and probably your local force about how peachy everything is. It isn't. "What are the benefits of Airwave?" o) Greatly improved coverage throughout force This is a mixed bag. I have personally witnessed communications being crystal clear in the depths of town x (read: middle of nowhere where previously neither UHF or VHF could penetrate), yet o2 appears completely unable to give us a clear signal outside Major University, just yards from the major county motorway for which force Police, along with all other major A roads in the county, have contracted for 100% coverage. Reception is also **** poor in major City centre, major city centre, major city centre, major city centre and major city centre. If by 'coverage' they mean the ability to transmit something - anything! - then yes it has improved. I thought the point of 'communication' was being able to be understood when trying to transmit though. o) voice clarity and an end to background noise This partly goes hand in hand with the last entry. Voice is anything but clear. When in the control room I have my headset volume up to 120% on the touch-screen control equipment, and also have the built-in headset volume control set to 3 (max), and I still struggle to hear what anyone is saying the majority of the time. There appears to be a total lack of bandwidth available for clear voice communications, compounded by the effects of lack of coverage. It is essentially like the early days of Internet telephones, were 2 people across the world were attempting to communicate via 2400baud modems. It simply didn't work. The noise cancelling was sold to us to also be a major advantage. Why is it then that as soon as the officer turns on the sirens, I can't hear a bloody thing they are saying? The moment they step into a busy pub/club, all I can hear is music and background chatter. This feature doesn't work either. And for the cynics, regarding the volume - no I am not deaf. Switching back to UHF I car hear them fine. o) secure encrypted comms that prevent scanning of police transmissions Granted, the system is secure and encrypted. It also works quite fast. Most of the time. However this does mean that while the criminals can't listen in to transmissions, neither can anyone else. I know that in the past I have assisted the police when off duty by phoning in seeing a 'suspicious male' hanging around or hiding somewhere based purely on the description given out over the air by controllers a few moments earlier. We as a police service have now automatically excluded this unauthorised - but none the less appreciated - help. In an even more indirect fashion listening to 'force' transmissions on VHF, I have avoided accidents that have just happened, reducing the burden on the service either trying to attend, or who end up dealing with the resulting backlog of traffic. The same accident then appeared on my FM car radio via Traffic Announce about 20 minutes later. The end result was I also managed to get to work on time. o) digital comms that will enable staff to communicate by radio by phone or by text I won't discuss the radio element (radio as we mostly know it, e.g. broadcast or All Informed transmissions) as I think it covered well above. However the telephone element is fine, except that officers can only phone OUT from the handsets. For a maximum of 10 minutes. They cannot receive incoming *telephone* calls from anywhere, except Superintendants and control room staff. Useful. Text? Don't make me laugh.. if you saw how complicated it was to actually COMMUNICATE via text message, you wouldn't bother either. It isn't as simple as just write and send. If you want to send it to someone in the control room it is even worse. It is a system that will never be used, despite us being in the 'text generation' due to its complexity and high failure rate. Point to Point communications, e.g. using the radio as a radio, but for a private call between only two individuals works well providing there is no one transmitting on the main talkgroup. In a busy division like say busy division, there is rarely any point during the day where there isn't traffic on the main talkgroup, thereby rendering this otherwise useful service, totally useless. It is made even worse by controllers being told that they MUST NOT authorise talkthru on the main talkgroup. Great... so how do we communicate then? Oh.. I know.. back to personal mobiles it is then. o) access to local and national databases Oh? Where? I do not have access to PNC, local intelligence, or any other kind of database from my handset. My 'access to local and national databases' is as it ever was. Ask comms, go back to the car and use the MDT, or waste even more time and go back to the station. o) introduction of emergency button that will improve officer safety Yes.. when it works. Numerous times officers have pressed their emergency button only to be told 'call failed', or 'no coverage' or on pressing it for the required two seconds, find it doesn't fire because someone in comms happens to be talking at the time (Yes comms staff have a higher transmission priority than the emergency button!). How is it then that this will improve officer safety? I can't even hit people with my radio anymore if needs be, as the thing will shatter in to a million pieces. In UHF/VHF days I could scream 'HELP!' even if someone was talking. The controller would have a hard time trying to hear me over the other person when I gave details, but at least it was possible. With Airwave I just get 'BUSY' if I try and transmit, and end up in a queueing system. But of course, this improves officer safety. As a side note, when you are getting your head kicked in, have you any idea how long 2 seconds is...? The button is also extremely hard to push in and keep pushed in, all while trying to defend yourself. o) Improved communications will mean officers can be deployed to calls more speedily. If anything I have described above can be seen as 'improved', then you need to seek help immediately. There was never a problem deploying officers the old way. The majority of the time VHF/UHF worked fine, or as a last resort sending the job to the car MDT. o) Staff will be able to access information regarding incidents, people or vehicles directly through their Airwave radios. Yes, we can retrieve some information regarding incidents, but it is via text message, which we need to send first to request. It is a convoluted process and by the time we have finished typing out the request text message (which contains a lot of special characters like #), we'll probably be there. I cannot access any information regarding people or vehicles directly via by handset. I suspect when we are finally able to it will be via the same method, e.g. text, and will be quicker to call the PNC desk and ask. Text messages are also limited to 120 characters. Not very useful at all. The last two sentences consisted of 73 characters... o) Improved communications will mean less time in the police station and more time on the streets. Pure propoganda and an attempt to justify the 2.3 billion pound price tag for the system. How improving communication will result in me spending less time in the police station is a mystery. Is there a feature of Airwave that automatically completes my paperwork for me? Please tell me! I will gladly use it no matter how complex. o) The ability to communicate directly with other forces and other emergency services. Neither my county's fire or ambulance services subscribe to airwave. I can chat to neighbouring forces if I want to, but the only force I personally border with the majority of the time is a big expanse of water.. so no advantage there. o) "Our colleagues in other forces are already catching more criminals as a result of using Airwaves digital technology." One word. Tripe! Airwave offers nothing in effect - due to the technical problems - that MASC or similar technologies doesn't offer already. Pure propoganda again. Yes this is a humerous, but none-the-less serious look at the state of play in todays police radio service. Don't flame me for my comments and points of view. I'm sure if you speak to other officers of any number of forces, you will get a similar view point. If you got this far, congratulations and thanks for reading. The next time someone in authority mentions airwave to you, perhaps you'll remember this post and be able to raise a few points with them. It should be an interesting conversation... that is, if they decide they want to continue to talk to you at all... Yours, PC 5029 Concerned Officer. Some Station, Some Force, Some Where. |
