What You Need to Know About Two-Way Radio Frequencies for Your Workplace Applications

Sometimes, coordinating multiple activities in your firm can be quite difficult especially when you are dealing with a large group of employees. Text messaging and paperwork is not only time consuming but also hard to use concurrently with some of the activities in the workplace. Thankfully, two-way radios can help you sort out this problem by facilitating prompt communication between your workers through voice messages. Two-way radio can transmit and receive radio signals, enabling prompt two-way communication between different people, unlike broadcast receivers that can only receive content. Two-way radios rely on bands of frequencies (electromagnetic waves) to transmit information. The following is a discussion about the frequencies used by two-way radios to help you gain insight and make better consumer choices: 

Very High Frequency Radio

Very High Frequency (VHF) radios are designed to cover more distance with little power consumption during communication. This is because they use long sound waves that do not travel far above the ground level. They are ideal for job sites where you can achieve a clear line of sight with minimal to no obstructions on the communication path between those who are using the VHF radios. Since the VHF radio waves are long, it is hard for them to travel around obstructions. This interferes with the quality of the sound transmitted. Ideally, VHF radios are suitable for use in work places like large water bodies or open fields like golf courses.

Ultra High Frequency Radios

Ultra High Frequency (UHF) radios rely on short waves for communication, unlike the VHF radios. These short waves easily travel around obstacles on their path. This means that UHF radios still work well in areas with many obstructions like walls, metal barriers, hills and thick vegetation. The quality of the sound received is not dependent on a clear line of sight between those who are communicating. For unpredictable situations in the workplace, UHF radios are preferable because of their ability to function well in varying outdoor conditions.

Channels

Channels allow you to partition the frequency signal transmitted among the various users. You need them to organise the flow of the communication so that your employees can select the specific person that they want to communicate with. Each department at the workplace can have its channel. Both VHF and UHF radios come with varying capability regarding the number of channels that the user can tune in to. When buying two-way radios, ask about the number of channels available to ensure that you meet the current and future expectations of your firm.

Remember to choose the same band (either UHF or VHF) when buying the two-way radios. Don't mix them because inter-band communication is not possible.
