Walkie-talkies, or two-way radios, allow easy communication between employees whilst working at large locations such as warehouses, construction sites, retail stores, and even in office blocks. They normally come with a docking station for battery charging, and will typically have sufficient battery life to last through a long working day.
You’ll find various features on walkie-talkies:
- PTT: Press or Push to Talk operation uses a dedicated receive and transmit button for complete ease of use.
- VOX: a hands-free voice activation mode for use with a headset.
- Battery meter.
- Audible low-battery indicator.
- Sleep mode: preserves battery life below a predefined voltage level.
- Channel scan: enables quick response with multichannel communications.
- Auto squelch: automatically detects and cancels out background noise.
- Room monitor mode: automatically detects sounds or voices in a room for hands-free transmission.
A Personal Mobile Radio using a 446 MHz UHF wavelength (PMR446) can be used in most countries of the European Union without an operating license and free of airtime charges. To comply with this standard, the radio must have a built-in antenna and the maximum radiated power must be within 500 MW (0.5W) ERP. Most PMR446 walkie-talkies are rated at the maximum 500 MW.
A PMR446 radio uses up to 8 available channels, each with 38 different interference elimination codes (sometimes called ‘sub channels’) for a total of 304 channel options. By setting two handsets to a corresponding combination of channel and code, communications can be fine-tuned for optimum clarity.
