Walkie Talkie

walkie talkie

A walkie talkie is an easy and effective way to communicate in areas where mobile phones can’t get a signal. Working off single frequency wireless signals these hand-held devices are popular with outdoors enthusiasts and families. They’re great for family camping trips or to keep kids entertained and safe during outdoor activities.

Walkie-talkies convert your voice into radio signals which are transmitted across the electromagnetic spectrum at the speed of light (186,000 miles or 299,338 kilometers, per second). These radio signals are only received by other walkie-talkies that are on the same channel as yours. When you press and hold the push-to-talk (PTT) button your message is broadcast, and when you release it you hear a ‘roger’ beep to confirm that the transmission went through. The ability to chat with multiple people on the same channel at the same time makes two-way radios the go-to choice for small businesses and rescue teams.

How much range a walkie talkie has is one of the most important considerations when shopping for one. However, it can be difficult to judge this metric from the radio specifications alone as manufacturers list maximum ranges under ideal conditions. Moreover, real-world usage can be affected by obstructions such as mountains, cars and steel structures.

Consumer walkie-talkies typically have a Very High Frequency (VHF) or Ultra High Frequency (UHF) designation, while business radios have a licensed radio frequency. This means that they can operate on frequencies reserved for commercial use and have a greater operating range than consumer models. They’re used in settings such as construction, security, warehouses and even hospitals.
