How Walkie Talkies Rugged Phones Work?
Free Intercom: Walkie Talkie Rugged Phones
Cell phone technology advances at a mind-warping rate. But cell phones are still just really fancy 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.
How Walkie-talkies Rugged Phones Work
Transceivers
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.
Electromagnetic Spectrum
Let’s say you’re whitewater rafting with a group of friends on a remote river, in an area where there’s zero cell phone coverage. You depress the PTT button on your radio to chat with group members. As you speak, the walkie-talkie converts your voice into radio signals. Those signals are part of the electromagnetic spectrum, so they travel at the speed of light (186,000 miles, or 299,338 kilometers, per second) to all the other radios that are within range and on the same channel.
FRS & GMRS
All walkie-talkies are built to work on specific radio frequencies. In the United States, the primary frequencies designated for general public use are called Family Radio Service(FRS) and General Mobile Radio Service(GMRS). FRS or GMRS radios operate at frequencies in the 460-MHz range. The government also sets aside frequencies for corporate use, called Business Band, which includes frequencies between 450 and 470 MHz.

More and more walkie-talkies also come with ruggedized components so that they’ll withstand the abuse of the outdoors. Many are water-resistant and some even float. And many models now come with voice activation (VOX) so that you don’t even have to press a button to begin speaking.
Advantages of having Walkie Talkies Rugged Phones
As a result of these myths many institutions, without understanding the benefits of walkie-talkies, keep themselves confined to cellular devices to plug gaps.
1. Group Communication
When it comes to group communication walkie talkies are boom over cellular devices. While you need to call each user separately and then connect them in a conference call in case of cell phones, in walkie-talkies you can achieve it at a press of one button. Businesses and agencies, such as event management, police, security, and construction, find walkie-talkies quite beneficial when it comes to group communication with ones at different sites.

2. Budget-Friendly
The cost of walkie-talkies is less than cell phones. Moreover, there are no regular monthly charges, service contracts, and calling minutes. Thus, there is no tension about call durations and bills. Also, workers can share a radio, cutting expenses by avoiding the requirement to issue one per worker.
3. Instant Connectivity
This is the most important advantage of using a walkie talkie over a cellular device. With only a press of a button, your connection is established for communication while with the cellphone a user has to dial the number, wait for a ring tone, and for the receiver to answer before communicating. Walkie-talkies are thus most important when the speed of connectivity is very important and is a priority.
4. Interaction Clearness
While a lot of factors affect the calling quality of cellular devices, walkie-talkies undergo all the factors and still give you interaction clearness. Unlike cell phones, walkie-talkies include functions that lower wind sound and allow resistance to vibration, severe temperature levels, and wet conditions.
