How Do Walkie-Talkies Work?

A walkie-talkie or 2 way radio is a battery-powered transceiver (meaning that it can both transmit and receive radio signals). Walkie-talkies receive radio waves via an antenna and can also broadcast return signals (on the same frequency) via the same device.A 2 way radio essentially converts incoming signal into sound and outgoing sound into signal.The antenna on a walkie-talkie is home to various groups of electrons. These electrons respond to specific, pre-set channels (different groups respond to different channels). When the walkie-talkie antenna intercepts radio waves, the electrons translate those radio waves into electrical impulses, which then pass through the device and into a small processor, housed within the radio itself.The processor, in turn, converts the impulses into a sig...

UHF or VHF Two Way Radios – Which Is Better for Me?

Two way radio customers ask me all the time whether they should use UHF or VHF two way radios. The answer of course depends on where you're planning to use the walkie talkies. It is also important to know if you're already using two way radios because UHF radios won't talk to VHF radios and vice versa. There are some off brand radios that might allow UHF and VHF to be used on the same radio but UHF doesn't talk to VHF without additional technologies so for this article, they don't talk to each other.UHF stands for Ultra High Frequency. UHF is ideal for customers looking to use their two way radios indoors most of the time. UHF does a better job of penetrating through obstructions like concrete and steel. I recommend UHF technology any time someone has a jobsite where they work both indoors...

How Two Way Radio Works

One of the biggest selling points for 2 way radios is their simplicity. Radios are extremely easy both to initially set up and to use.The average two way comes equipped with a PTT (or Push To Talk) button. This button is held down when you want to speak into the device and released when you wish to hear the reply. It is important to say "over" after you have finished talking, this way the person receiving your message knows that you have finished speaking and aren't simply distracted or taking a breath. If you both try to talk at the same time, neither signal will come through.Most 2 way radios will operate at a decent distance, but as we discussed earlier this month, there are many variables that can affect a radio signal. Obstacles, be they man-made or naturally occurring, can seriously ...

CB Radios Are Easy to Buy and Install

Citizens' Band radio, or CB radio, is a system which allows simple, short distance radio wave communications. It operates within the 27 MHz band. Communications can be exchanged on one of 40 different channels. This type of radio is different from other types of personal radio services such as amateur or "ham" radio. Communication by this method in America no longer requires a license, as was the case in the 1960's. It can be used for both personal and business communications. The Citizens' Band radio service began in the USA in 1945 as an FCC regulated personal radio service. Citizens were permitted to conduct short distance radio communications for family or individual purposes. Today semi truck drivers and individuals living in rural America, as well as hobbyists in other countries prim...

Cheap Walkie Talkies In Place Of Mobile Phones

Today, almost everyone owns a modern mobile phone. Most of these modern phones have the availability of wireless internet, which is why people are always in touch without spending a lot of money. Because of the convenience provided by this modern technology, people never stop to think about other communication devices like walkie talkies. They are only seen as toys for children to play with and most people do not own these. However, what we often do not realize is that a walkie talkie can be extremely handy. It can actually be a lot more effective than a mobile phone in several situations.This is because while mobile phones are very useful, their technology can be limited in certain situations. Their usage can also be hampered by the fact that you may not be able to carry them everywhere. ...

Two Way Radios in Primary and Acute Healthcare

Communication plays a crucial role in healthcare. Timely dissemination and sharing of information is critical for acute healthcare providers. Similarly, primary healthcare can be easily administered by using practical and handy communication channels. However, there are several factors that need to be taken into account before deciding upon an effective mode of communication in both primary and acute healthcare institutions. Reliability, coverage and confidentiality of transmitted information along with the institution's capacity in handling the equipment, play an important role. Healthcare institutions can largely benefit from a mobile clinical staff and two way radios can provide prolific results if used effectively for sharing information.
