If the last time you used a two-way radio you just talked into it and your voice came out of all the others - things have moved on. Basic models still do this of course, it’s the primary purpose of a radio - but you can do so much more. Anyone who has used a pair of cheap walkie-talkies knows how easy it is for other people, not involved with your business or event to join in with your conversations. Sometimes, in busy areas there simply are not enough Government legal frequencies, so OFCOM try to organise it sensibly. This can mean the local DIY warehouse being allocated exactly the same frequency as the Coffee shop half a mile away. To prevent each other being bothered by the other, the radios can be programmed to simply ignore them. In the main, this works pretty well. If you are organising a large event, and want to have the car park people separated from the catering, then you just need a little more flexibility. Once you start to have lots of radios in your system, it gets difficult to work out who is who  when you hear (or often half-hear) a call because you were doing something else. This is where radios that have ID features come in. It can be simple - if radio 2 puts out a call, all the radios show radio 2 in their display. You could even change it so the radios show useful names - office - workshop - stores, or even your staff names if they have dedicated radios. Take it a step further and you could call these people direct. Selecting stores would mean your call only comes out of the right radios - everyone else’s stays silent. This is also all on the traditional analogue radios - we haven’t even considered what digital can do yet!


I suppose the main benefit of digital is the security. If it needs to be private, it can be. Analogue can be listened into by people who have modest means and time. Digital is to all intents and purposes secure. Digital has all the same useful features with groups of users but can extend this considerably if you need to work across different sites - connecting them seamlessly via the internet.

There are also performance differences between analogue and digital. As distance increases, analogue gets hissy and intermittent. Digital either works or doesn’t - so you must decide what is best for you and think about geography - we can help with this, advising on what is best - for you!


There are also different types of digital systems - perhaps best to think back to VHS and Betamax. Both have fans, but the main consideration is that they are just different.
