The Advantages of Digital Two Way Radios
Two way radios have turned to the digital world, just like their cell phone cousins did way back when. If you can remember when cell phones first came out, they operated with analog signaling, which resulted in a lot of static. Fortunately QUALCOMM invented CDMA technology which pioneered the switch to digital communications.
With digital cell phones, you either have the reception or you don’t. Calls drop in or out, but you never have static. The same principles hold true for digital two way radios. The Motorola MOTOTRBO system (when operated in digital mode) and the Motorola DTR550 and DTR650 have excellent audio quality with no background noise. In certain applications, digital frequencies penetrate structures and objects easier than analog.
Besides the audio quality, another advantage to digital two way radios are the calling features. These include:
- One to one calling. This is a nice feature when you need privacy.
- One to many, or public group call. You can broadcast your message to all the walkie talkies in your fleet.
- Private group call. Managers can communicate with specific talk groups.
DTR 650’s have a manager mode option which allows you to cue up another DTR radio and monitor what the user is hearing. You can also disable a walkie talkie if it gets lost or stolen.
The batteries on digital two way radios also last longer than analog. The DTR series carry up to 45% longer life and the MOTOTRBO two way radios come with a standard IMPRES battery.
