When it comes to business walkie-talkies in the UK, it's important to know the distinctions between UHF (Ultra High Frequency) and VHF (Very High Frequency) radios. UHF radios operate within the frequency range of 400 - 470MHz, while VHF radios use frequencies between 136 - 174MHz.
UHF radio signals are limited in their range compared to VHF signals, but they excel at propagating within buildings. This makes them ideal for indoor communication, where VHF signals may struggle to penetrate structures effectively.
On the other hand, VHF radio signals can travel much further than UHF signals, making them suitable for outdoor use over long distances. However, they may encounter difficulties when it comes to transmitting through buildings or other obstacles.
Another important feature to consider is VOX (Voice Activated Transmit). This functionality allows users to transmit without the need to press and hold a button. Instead, the radio automatically detects sound above a preset threshold and transmits accordingly. This hands-free operation can be convenient in various situations.
Walkie-talkie radios, also known as two-way radios, are portable devices powered by batteries. They are designed to be small enough to be carried easily, either by hand or clipped to a belt or pocket. The effective range of walkie-talkies varies from a few hundred meters to a few miles, depending on factors such as power output and the terrain or buildings between the radios.
The power output of a walkie-talkie is typically measured in watts. Generally, higher power output results in a longer effective range and a clearer signal. Standard walkie-talkies usually have a power output of 4 or 5 watts. However, some radios comply with regulations that limit the power output to 0.5 watts, allowing them to be used without a license. An example of this is the PMR446 system.
