Licensed Radios (UHF & VHF)

The primary difference boils down to power and privacy. Licence-free radios (PMR446) are limited to just 0.5 watts of transmit power and operate on shared public frequencies, which often leads to static interference and overheard conversations. By contrast, a licensed 5 watt two way radio broadcasts at up to ten times that power, punching through concrete walls, steel structures, and dense terrain. Furthermore, a dedicated Ofcom licence grants your business its own secure, private frequency, eliminating cross-talk from nearby users and securing your confidential operations.

Licensing is easily obtainable by applying to Ofcom using the form (here).

When selecting your wireless network, you will need to choose between UHF and VHF radios. Both frequencies have distinct physical properties that change how signals travel through the air and interact with obstacles. Choosing the correct band ensures optimal site communication and keeps your teams running smoothly.

The difference between standard unlicenced, use out of the box, two-way radios are that they do not require a licence to use them. That is because they come with a set frequency band you can use PMR446. The downside is that lots of people use this same frequency band and it does not offer the same outdoor range as a decidated, licenced radio tuned to your own frequency band.

With licenced radios, you need to apply to Ofcom, to rent your own frequency. This means you can be sure that only you and other users related to you will be using the same frequency band and these radios tend to be more powerful and offer greater coverage outdoors.

There are two types of licenced long-range two-way radios that we stock here at PMC Telecom – Ultra High Frequency and Very High Frequency (or UHF and VHF for short). Each of these is better suited to specific uses and locations.

Ultra-High Frequency (UHF) radios operate on shorter wavelengths, making them exceptional at navigating indoor environments. If your primary focus is indoor warehouse radios or security radios operating within built-up urban zones, UHF is the ideal choice. The shorter waves easily pass through windows, open doors, and dense structural steelwork without losing signal strength.

Very High Frequency (VHF radios) use longer wavelengths that travel incredibly well over open spaces. If your team requires heavy-duty construction radios, agricultural coordination, or outdoor event management across expansive, unobstructed landscapes, VHF will deliver superior range and clarity.

One of the most frequent questions we encounter is exactly how much distance these units can cover. Because licensed models transmit at a higher wattage, they easily outperform licence-free alternatives, but maximum distance is never a single, static number.

The ultimate range of your licensed walkie talkies depends heavily on your local environment. In an open landscape with a clear line of sight, a high-powered handset can communicate over several kilometres. However, inside a dense city centre or a sprawling industrial complex, physical obstructions like reinforced concrete, terrain elevation, and electromagnetic interference will naturally compress that radius. For massive sites, range can be extended even further by integrating repeaters into your radio setup.

High-power handhelds are indispensable wherever coordinates span large footprints or complex architectures. They ensure that split-second decisions can be communicated instantly, reducing downtime and protecting staff safety.

• Construction & Heavy Industry: Rugged construction radios keep crane operators, ground crews, and site managers perfectly aligned.

• Logistics & Warehousing: High-capacity warehouse radios allow seamless stock management across massive distribution centres.

• Private Security: Reliable security radios ensure discrete, instant communication during critical crowd control or asset protection details.

• Event Management & Hospitality: Perfect for coordinating large-scale festivals, stadium operations, and sprawling resort grounds.

To get the most out of your investment, look closely at hardware specifications that match your daily operational environment.

A radio is only as good as the system supporting it. Long-term performance relies heavily on exceptional battery life to power through extended twelve-hour shifts without fade. For hands-free operation in noisy environments, pairing your fleet with heavy-duty radio headsets keeps audio clear and intelligible. Management becomes effortless back at base when you deploy multi-unit chargers to drop all handsets into a single, organised charging station overnight. Protecting your gear with the right radio accessories ensures longevity and lowers your total cost of ownership.

Navigating wireless regulations can feel daunting, but ensuring legal compliance is straightforward with the right guidance.

To operate high-power equipment legally in the UK, businesses must secure a valid licence from Ofcom. This governance manages frequency allocation to prevent local organizations from bleeding into each other's channels. Whether you need a simple, low-cost Simple UK Light licence or a technically tailored Technically Assigned frequency for a specific geographic footprint, obtaining your paperwork ensures your equipment operates legally and free from external interference.

While traditional analogue radios remain a dependable and cost-effective choice for basic voice transmission, modern digital radios offer significant performance upgrades. Digital units leverage advanced error correction to deliver crystal-clear audio right to the very edge of their coverage area, eliminating the progressive static hiss typical of analogue signals. Digital systems also introduce intelligent features like selective individual calling, text messaging, GPS tracking, and dramatically superior battery efficiency.
