How Slimmed-Down Two Way Radio Boosts Convenience

Technology has a tendency to keep making everything smaller as it evolves. Unless we’re talking TV screen sizes, of course.

For mobile technology, this has obvious advantages, especially in the workplace. When you are on your feet all day, you don’t need heavy, cumbersome devices weighing you down.

When you are carrying out repairs here and there, moving equipment or furniture about or handling deliveries, you need your hands free. Any device you carry, you want to be able to tuck it away in a pocket where it won’t get in the way.

In the FM sector, as across business and industry in general, two way radio is preferred to mobile phones for work-based communication because it offers better audio and more reliable signal coverage. Two way radio handsets are also designed to be tougher and more durable than your average smartphone, and therefore more capable of withstanding the knocks and drops likely to occur with heavy manual use.

But traditionally, due to both their superior audio systems and robust chassis design, two way handsets have tended to be on the bulky side.

All of that is now changing. With new technologies allowing manufacturers to reduce the size of HD quality speakers while using software to boost the clarity of the signal, the new wave of digital two way radio handsets are dropping in size without losing any of their functionality. That is good news for FM professionals looking for lightweight, portable devices that do not compromise on quality.

Ultra-Compact Two Way Radio
Design wise, two way radio manufacturer Hytera has looked to mobile telephones as the model for its latest ranges. The Hytera PD365 takes the look of the original Nokia handsets, with the central scroll key and the green call and red hang up buttons. The PD365 is a fine example of an ultra-compact, easy-to-carry two way radio solution for complete convenience.

At just 165g, it weighs almost half of what some of the most popular two way radio models on the market weigh. It fits easily into the palm of the hand, despite including a three-line display. And it loses none of the functionality expected from a modern digital handset, supporting text messaging as well as voice, private, group and whole network calling, and has four programmable buttons for easy one-touch operation.

Another similarly lightweight two way radio option is the Motorola SL2600. The SL2600 maintains more of the classic ‘walkie-talkie’ look, but shrunk down into an ultra-modern, sleek body that weighs just 190g. Despite that, the SL2600 is built for tough environments, with high resistance to water, dust and extremes of temperature. Its main innovation is the use of an OLED display, which shows key information through the front of the chassis without the need for a screen.

To date, the most radical innovation in ultra-compact two way radio design is the Motorola CLK446. Designed to be worn on a lanyard around the neck, it weighs an incredible 68g, and resembles a pager in appearance. As an analogue radio operating on open public frequencies, the CLK446 lacks some of the features and security of larger industrial-class digital models. But it demonstrates exactly what the possibilities for slimming down two way radio are.

Who knows – at this rate we will soon be talking about premium quality two-way radio delivered via nothing more than an earpiece.
