Do you run a retail business or operate in a high risk environment? Perhaps you’ve heard of walkie talkies or two way radios and wondering how they can help you improve communication or enhance security for your team. In this piece, we are going to look at Walkie Talkies: What they do, how they work, and how they can benefit you. So let’s begin.
Walkie Talkies: What Are They?
Before cell phones became popular, you might have watched movies where walkie talkies were used. Or perhaps you might have used a walkie talkie and it might have been fun. A few decades back, walkie talkies were the most effective way of sharing information within a short or medium range. To date, walkie talkies are still used in several industries such as security, manufacturing, warehouse, healthcare, production among others.
Walkie talkies are portable handheld radios and they communicate wirelessly using radio waves on a single frequency band or a shared one. They were first developed in the 1930s by a Canadian inventor called Donald Higgs and an engineer named Alfred Gross. They were named walkie talkies with the fact that you could talk while walking.
Each battery-powered unit contains a transmitter/receiver and antenna which helps to send and receive radio waves. There is also a loudspeaker, which also functions as a microphone and a push-to-talk button (PTT). The loudspeaker-cum-microphone works just like an intercom: because a speaker and a microphone contain the same components. However modern options like Motorola walkie talkies have separate loudspeakers and microphones.
How Walkie Talkies Work
First and fire most, people using walkie talkies must be connected to the same channel or frequency band. The handsets must all be set to receive, so the microphone-cum-loudspeaker is set to the loudspeaker. When one individual wants to talk to others, they must hold the push-to-talk button on their handset.
The loudspeaker will automatically change to a microphone. As the person talks, the words are converted into radio waves and are broadcast on a pre-arranged channel. Radio waves are part of the electromagnetic spectrum and they travel at the speed of light (300,000 km/second) meaning the waves are picked up instantaneously by the rest of the handsets.
The radio waves are then converted back into fluctuating electric currents and they are used by the loudspeakers to reproduce the sound of the talker’s voice. Once the talker is done, he or she will say “over” and then has to release the push-to-talk button. The radio will then switch back to listening mode and then another person can talk.
Areas Where Walkie Talkies Are Used
Walkie talkies are widely used in different industries such as construction, healthcare, emergency, security, military, transportation, tourism, manufacturing etc. Depending on the needs, users can either choose analog or digital two way radios. Modern two way radios allow a member to call a single individual instead of the entire group or make emergency announcements to all team radios even if other users are on different channels.
They also come with a range of features; they are available in a range of bundles and brands. There are also childrens walkie talkies which are domestically used for games, and they also help parents to stay in touch with their children. They can also be used to improve communication skills in kids whether at home or in children’s daycare centres.
As a user, you will have to decide whether to go with a licenced or licence-exempt two way radios. You can use licence-free two way radios if you’re working within a small area. However, you will need licenced two way radios if you need a large coverage or working in a more professional field.
Why Use Walkie Talkies?
Modern walkie talkies are versatile, built to last, and easy to use. They can be used in both domestic and commercial areas. Modern two way radios offer lone worker monitoring, one of the most effective ways to ensure safety in high-risk working zones.
With these devices, 24/7 communication is guaranteed between individuals working on the same site or different departments within the same building. They allow staff access or obtain assistance or advice in case of an emergency. They can also help call for more help from the emergency service providers.
Channel scanning enables the users to monitor various channels and respond when a transmission comes through. The scan feature can be programmed to include or exclude channels from the scan. It should be noted that scanning fewer channels makes the scan faster and in case the transmission is found, the radio will stop and pause. This allows the operator to respond to the transmission before continuing its cycle through the selected channels.
It can be confusing when it comes to choosing the right walkie talkies to meet your needs. Nevertheless, there are many brands on the market.
