Two way radios are ideal for those who are unfamiliar with the technical specifications of traditional walkie-talkies. They work on UHF Frequency band 400-467 MHz and support several distinct channels, usually around 7. More basic radios such as FRS radios and walkie-talkies can link with each other to a maximum distance of up to 5 miles, while other types of radio such as the GMRS kind can work over much larger distances. But how does it work? This article will shed some light on this interesting technology.
The reason that two way radios work so well is that they operate on much wider frequency bands, covering much larger areas than the older radio models did. As a result, they cover much more ground and are more reliable and versatile. Walkie-talkies are mainly suitable for outdoor use, but they can also be used in buildings or apartments to keep both employees and the public informed about events taking place within or outside the building. In fact, these devices are becoming so popular that they are often used to relay instructions, weather alerts and even business critical data.
But how do two way radios work? The process is actually quite straightforward and very much like using a regular radio. The basic principle remains the same: a radio transmitter broadcasts a signal to a receiver, which then picks up the signal out on the same channel where the radio waves will be converted back into audio.
There are two kinds of two way radios: personal and commercial. A personal radio is meant for personal use by an individual or a small group. This kind of a radio is mostly used to communicate short messages such as weather reports, traffic delays and other similar information. These personal devices are much cheaper than walkie-talkies since they do not need to be connected to a telephone line or a power source, and most do not require a license for use.
Commercial two way radios are designed for larger groups and can easily accommodate up to 15 people or even more, making them perfect for use in businesses and buildings such as hospitals. They can be connected to power lines to recharge batteries, or they can simply remain plugged into any wall outlet and used as a stationary device. The cost of commercial walkie-talkies is slightly more expensive than personal devices because they are mass-produced to a higher specification, are more powerful, and have a greater range of features.
However, most large companies are investing in this technology for their employees, especially in areas where emergency situations and disaster recovery are frequent, and in businesses where communication is key, such as restaurant two way radios for the catering and hospitality industry. Many retailers offer packages which allow businesses and other commercial entities to purchase multiple units at wholesale prices. For this reason, two way radios bought in bulk can be quite cheap.
There are several manufacturers of this kind of radio. Some of the best-known ones are Kenwood and Motorola. Two way radios from Kenwood are renowned for their quality and durability, although they are quite pricey compared to walkie talkie devices. Motorola also makes good two way radios, although there are benefits to each kind and the right one for you depends on your specific requirements.
One of the features that makes these two way radios popular among users is their ability to handle multiple frequencies. They work as regular walkie-talkies but can also hold other uses such as sending out security signals, distress signals, and some even have GPS features.
If you want to use a two-way radio for something other than emergency or general purposes, then you should buy them only in quantities sufficient for your intended use. Do not hesitate to ask the seller if there are more affordable options available for your intended use, or ask for their advice on which models will work best for your needs. This will save you from buying the wrong kind of two-way radios when all you really need is something simpler.
Moreover, remember to check for compatibility between your two-way radios and other radio communications devices before purchasing. This will ensure that you get full value for your money and you do not spend unnecessarily for things that won't be compatible with your existing kit.
