Walkie talkies are a popular form of two-way communication used in many areas of life, including emergency services, security, military, construction, hospitality and transportation industries. They are easy to use and provide clear audio from far away.
How walkie talkies work:
Walkie-talkies are a type of radio that works on wireless frequencies, in a half-duplex system where only one person can speak at a time, but any number of people can listen. To speak, press the push-to-talk button (PTT), which switches the radio from receiver mode to transmitter mode and activates the microphone.
What to look for in a walkie talkie:
A good walkie talkie should give you the capability to communicate in places that do not have cell signal coverage and also allow you to chat with multiple people at once in specialised areas, which is a feature that mobile phones do not offer. It should also be able to communicate in a range of high-frequency ranges, such as VHF and UHF.
What to avoid:
The most common problems with walkie-talkies are: – Insufficient battery power, which means the device is unable to transmit or receive messages. – Static during transmission, which could be caused by a dirty antenna.
The most basic walkie-talkies typically run on AA or AAA batteries, but high-end models use rechargeable lithium-particle, nickel-metal hydride, or nickel-cadmium batteries. Batteries should be replaced regularly and not recharged for long periods of time. They should also be stored in a dry, well-ventilated area to help prevent overheating.
