How 2 way radios Work

With a huge amount of information on the net about walkie talkie headphones’s it can be hard to discover the top and most direct information. here is a piece from a reputable website that i believe as true, don’t quote me on it but please read and enjoy

Cell phone technology advances at a mind-warping rate. But cell phones are still just really fancy Kenwood radios, and they have an Achilles heel — they’re completely helpless without a network of nearby cellular towers. Walkie-talkies, though? These old-school radios make short-range wireless communications possible in places where cell phones go to die.

Walkie-talkies are wireless, hand-held radios that are small enough to take just about anywhere. They look a lot like cordless phone handsets, with a body that includes a microphone and speaker, as well as an antenna. Unlike a phone, though, a walkie-talkie’s speaker and microphone are placed right next to each other, and the speaker is much louder, so that anyone within earshot can follow the conversation.

Walkie-talkies are battery-powered transceivers, meaning they can both send and receive radio messages. They have a half-duplex channel, which indicates that only one walkie-talkie on a channel can transmit a signal at one time, although many radios can receive that same signal. In other words, unlike your phone, in which both parties can interrupt or add to the conversation in a ceaseless flow of sound, walkie-talkies use a push-to-talk (PTT) system — you have to press a button in order to speak, and you have to release that button to hear sound coming from other units.

Because you don’t have to dial a number each time you want to transmit, walkie-talkies are quick and easy to use. And best of all, they don’t rely on finicky cell phone signals. The handsets transmit directly to each other, so they still work when cell networks fail during natural disasters or power outages. They’re designed primarily for short-range communications, in which groups of people are within a few miles of each other.

Businesses use walkie-talkies so that employees can chat efficiently in and around their indoor and outdoor structures. Wilderness lovers tote walkie-talkies so that they can keep in touch during hiking or hunting trips out where cell phone cover age is non-existent. Even baby monitors employ one-way walkie-talkie technology, so that you know if Junior is sleeping peacefully or attempting escape.

Walkie Talkies in Motorsports

So to continue my run of content on this website, I’ve planned to share one of our favourite content pieces this week. I was hesitant to add it to a blog as I really didn’t want to offend the original author, but I hope he/she is glad that I loved reading their work and planned to share it with my readers.

walkie talkie necklaceEvery employer has a duty of care under the Health and Safety at Work Act 1974, to ensure so far as is reasonably practicable, the health, safety and welfare of all its employees in the workplace and equally that persons not in their employment are “not exposed to risks to their health and safety so far as is reasonably practicable” – with the Corporate Manslaughter and Corporate Homicide Act introduced in 2007, the implications for enterprises in the public and private sectors of not taking lone worker protection seriously have escalated.

Walkie Talkies are already widely in use in lone worker applications across chemical and manufacturing plants, utilities, mining, security and transport industries where personnel often cover large, remote areas or operate in hazardous environments.

However, with the increase in flexible working times, care in the community services, home deliveries and reductions in workforces operating from fixed locations, more people than ever are now operating as lone workers, often in situations where they may be exposed to potential accidents and inappropriate or violent behaviour.

While the reliability and quality of any Kenwood two-way radio would prove to be an asset in most lone worker scenarios, the NEXEDGE® range of digital two-way hand portable walkie talkies and mobile in-vehicle two-way radio units offer much more than the ability to transmit voice and data instantly and efficiently.

All models feature Emergency Key and Emergency Call features as standard, while some advanced models additionally offer Lone Worker and an Emergency Advanced Motion Detection Function, which make them ideal for incorporating within a robust health and safety and lone worker policy.

NEXEDGE® Digital Two-way Radios with Lone Worker features include both hand-portable walkie talkies and mobile in-vehicle units.
