An Icom LTE radio is a professional push-to-talk (PTT) device that works over the UK's 4G/LTE and 3G mobile networks rather than traditional radio frequencies. It looks, feels, and operates exactly like a conventional two-way radio - press the PTT button, speak, and your voice reaches the intended person or group instantly.

The key difference is range: instead of a few miles, you can reach anyone in your network anywhere in the UK, as long as they have mobile signal.

No. Icom LTE radios are purpose-built two-way radio terminals, not mobile phones. Key differences include:

• No dialling. Press the PTT button and speak instantly to one or many users
• Rugged, IP67-rated hardware built for commercial and outdoor environments
• Closed, encrypted private network, not a consumer mobile service
• Built-in Man Down, Lone Worker and Emergency button features
• Pre-defined text messaging (not a standard keyboard phone interface)
• Custom SIM that only works in the device, not interchangeable with phones
• Typically much cheaper per user than a business mobile contract

Getting started is straightforward. You purchase your Icom LTE handsets and/or mobile radios from GTC, and we configure the SIM and server connection to your requirements before despatch. Once you receive the radios, you power them on and you're ready to communicate. No site visits, no engineers, no radio programming required.

No. This is one of the biggest advantages of LTE radio over traditional PMR radio. There are no repeaters, no aerials, no cabling and no radio programming required. The system uses the existing 4G/LTE mobile network infrastructure already in place across the UK.

This also means you can instantly deploy to any new site or project location anywhere in the country without any preparation work.

No. Because Icom LTE radios operate over the mobile data network rather than licensed radio frequencies, they do not require an Ofcom radio licence. This simplifies procurement considerably and removes an ongoing administrative burden.

There is no fixed range limit. Icom LTE radios work anywhere in the UK that has 4G/LTE or 3G mobile signal. One user could be in Poole, another in Aberdeen, the communication experience is identical.

The custom SIM is configured to roam across the UK's major carriers (Vodafone, O2 and EE), which significantly reduces the risk of signal loss in any single dead spot.

If there is no mobile signal, the radio cannot communicate, just as a mobile phone would be unable to make calls. The multi-network SIM significantly reduces dead spots by roaming between Vodafone, O2 and EE, but in genuinely remote areas without any mobile coverage, the radio will not function.

For mixed-use environments (e.g. working locally in a building or underground as well as on open roads), the IP730D hybrid radio may be a better option as it also operates on conventional VHF/UHF radio frequencies.

The server that manages the Icom LTE network is located in a secure UK facility. Icom applies enterprise-level encryption to all communications running through the server, and the system operates as a closed private network, completely separate from the public mobile phone system.

Icom also handles all system monitoring, network management, and radio firmware updates remotely through this server connection.

Yes. Each Icom LTE radio requires a dedicated custom SIM card. This is not the same as a standard consumer SIM card; it is pre-configured specifically for use with the Icom LTE system and the private network server.

The Icom data plan is available on 2 or 3-year contracts and includes:

• A fixed monthly fee (agreed at point of sale)
• The custom SIM card with multi-network coverage (Vodafone, O2 and EE)
• Access to the closed, private Icom network server
• Icom system monitoring and network management
• Radio firmware updates managed and delivered by Icom

Pricing varies depending on the number of units and contract length. Contact GTC for a tailored quote — we can put together packages for both outright purchase and contract plans.

The Man Down function uses motion sensors within the radio to detect if a user has fallen or become stationary for an unusual period of time. If triggered, the radio sounds an alert and then automatically opens a live microphone feed so other users can hear what's happening in the vicinity of the downed worker.

This feature is particularly valuable for workers in hazardous environments such as highway maintenance, security, lone working, or any outdoor operational role.

The Lone Worker function requires the user to interact with their radio at regular set intervals (for example, every 15 minutes). If the radio is not used within that window, an alert is triggered to other users or a control room, prompting a welfare check.

This provides a systematic safety net for staff who work alone; particularly useful for night-shift workers, security patrols, and solo field operatives.

Yes. The RMS-IP Dispatcher software provides live GPS tracking for all radios in the system, viewable on a map from any PC, laptop, tablet or smartphone. Features include:

• Real-time location of all active radios
• Historical GPS playback for route verification
• Geo-fencing (alerts when radios enter or leave defined areas)
• Voice recording and call logging
• Text and voice messaging from the dispatcher console
• Emergency alert management

Yes. The Icom LTE system includes a break-in feature that allows a designated user (typically a manager or supervisor) to talk over an active conversation in urgent situations, rather than waiting for the channel to become free. This is particularly useful in time-critical scenarios where an immediate instruction must get through.

The main difference is range and infrastructure. Traditional PMR radio transmits on radio frequencies, limiting coverage to a few miles unless you invest in repeaters and infrastructure. LTE radio uses the 4G/LTE mobile network, giving you nationwide reach from day one with no infrastructure cost.

LTE also offers better audio quality (full duplex vs half duplex), built-in GPS tracking capability, and no licence requirement. However, traditional radio can work in areas without mobile signal (underground tunnels, some remote locations), which LTE cannot.

Yes. The Icom IP730D is a hybrid radio that supports both LTE (for nationwide coverage) and conventional VHF/UHF digital/analogue radio modes (for local communication). This means organisations can transition gradually, or maintain local radio capability in areas like buildings, tunnels or quarry sites while gaining nationwide coverage for mobile workers.

It's ideal for organisations working on large infrastructure projects, highway maintenance, or any operation that spans both local and wide-area environments.
