Why BVLOS Drones Need More Than 5G: The UK's Connectivity Stack Explained

Last checked: 1 October 2026. This source-backed explainer separates current UK authorisations from proposals and preserves an unresolved post-deadline Ofcom status as UNKNOWN.

When people talk about long-range drones, the conversation often starts with one number: range.

That makes sense for shopping. It is much less useful for understanding Beyond Visual Line of Sight, or BVLOS, operations.

A drone flying several kilometres away is not automatically operating safely, legally or reliably just because its controller can still exchange data with the aircraft. Routine BVLOS depends on a wider system: command-and-control communications, coverage, backup options, traffic awareness, operational authorisation and spectrum rules.

In the UK, that system is still developing.

The Civil Aviation Authority (CAA) says its current Future of Flight roadmap is intended to establish routine BVLOS operations by 2027. At the same time, Ofcom is reviewing how drones should access additional radio spectrum and how mobile networks can support more advanced operations.

The result is a useful shift in how we should think about drone "range":

For serious BVLOS operations, the question is not simply "How far can the drone fly?" It is "How can the aircraft remain reliably controlled, monitored and integrated into the airspace throughout the mission?"

This guide explains the UK connectivity stack in plain English, separates what is already available from what is still proposed, and identifies the parts that remain unresolved.

What BVLOS actually means

Under normal Visual Line of Sight (VLOS) flying, the remote pilot keeps the drone in direct sight.

The CAA defines BVLOS as flying where that visual contact is not maintained. Its public guidance also makes an important legal point: you must not carry out BVLOS flying unless you have an Operational Authorisation that permits BVLOS operations.

That means BVLOS is not simply a feature you "unlock" because a drone advertises a long control distance.

A manufacturer may state that a product can maintain a radio link over several kilometres under certain test conditions. That specification does not by itself authorise a UK pilot to fly beyond visual line of sight.

For beginner and VLOS flying rules, see our 2026 Drone Law Survival Guide and first-flight safety guide.

Most consumer drones use licence-exempt low-power radio systems, commonly in the 2.4 GHz and 5 GHz bands.

Ofcom's existing UAS framework explicitly says its specialist UAS Operator Radio licence does not replace the licence-exempt regime used by most ordinary drones.

For normal consumer flying, that distinction may never matter.

For scaled BVLOS operations, however, the aircraft may need communications that can remain available across a much larger and more variable operating area. Terrain, buildings, network coverage, interference, redundancy requirements and the type of mission can all change what a suitable communications architecture looks like.

That is why BVLOS should be thought of as a connectivity stack, not a single radio specification.

A high-level stack can include:

1. a primary command-and-control link; 2. a backup or alternative communications path; 3. telemetry and position data; 4. traffic-awareness or other safety systems; 5. monitoring by the operator or network; 6. the regulatory permissions covering both the radio equipment and the flight itself.

Different missions will use different combinations. There is no single communications technology that automatically solves every BVLOS use case.

The UK's existing UAS radio framework

Ofcom already operates a UAS Operator Radio licence for drone radio equipment that falls outside the normal licence-exempt consumer framework.

According to Ofcom's current statement, the licence:

  • covers all drones operated by the licensee in the UK and territorial waters;
  • has an indefinite duration, subject to an annual fee of £75;
  • can authorise specified radio equipment used for more advanced drone operations;
  • permits the use of mobile and satellite technologies, subject to agreement from the relevant network operator;
  • does not replace the licence-exempt low-power 2.4 GHz and 5 GHz regime used by most consumer drones.

There is another distinction that matters even more:

An Ofcom radio licence is not permission to conduct the aviation operation.

Ofcom regulates spectrum use. Drone operators must still comply with the CAA's aviation and safety requirements.

That separation — spectrum authorisation on one side, aviation authorisation on the other — is one of the most important concepts for anyone trying to understand UK BVLOS.

Why mobile networks matter for BVLOS

The mobile network is becoming an important part of the UK's drone policy discussion because cellular coverage can provide a communications path over much larger areas than a simple point-to-point consumer controller link.

Ofcom's July 2026 consultation states that BVLOS use cases often rely on mobile networks for primary command and control.

But Ofcom also identifies the weakness in relying on one network layer alone: there can be gaps in mobile coverage.

That is why the regulator is considering whether operators need access to additional spectrum that could provide another communications path in locations where mobile coverage is insufficient.

The UK Government has also made cellular drone connectivity a formal policy priority. Its 2026 Statement of Strategic Priorities tells Ofcom to continue working with industry and the CAA on the technical parameters and commercial licensing arrangements needed to support drone operations using cellular technology.

So the direction of travel is clear:

cellular connectivity is becoming part of the infrastructure for advanced drone operations — but it is not the whole infrastructure.

What Ofcom proposed in 2026

On 16 July 2026, Ofcom opened a consultation titled Enabling drone innovation and security.

It proposed allowing drone control links to use two additional spectrum areas on a time-limited basis.

1. 450 MHz

Ofcom proposed allowing frequencies between 453 and 462.5 MHz to be used for drone control links through three-year fixed-term licences.

It said this spectrum is mainly available in remote and rural areas.

2. 5030–5091 MHz

Ofcom also proposed making part of the 5030–5091 MHz band available for drone control, with 5040–5060 MHz as its preferred option.

The proposed access would run until 2032.

The same consultation also proposed a new drone-detection radar licence, but that is a separate use case from command-and-control connectivity.

Important: these are still proposals in this article

The consultation page states that responses were due by 30 September 2026.

As of our latest check on 1 October 2026, Ofcom's page showed Status: Open. We did not locate a final statement adopting the additional-band proposals.

So this article deliberately describes the 450 MHz and 5030–5091 MHz items as proposed, not current authorisations.

That distinction will be updated when Ofcom publishes a final outcome.

UK BVLOS connectivity: current versus proposed

Connectivity layer / band Main role Status checked 1 Oct 2026 Authority Key limitation
Low-power 2.4 / 5 GHz Common consumer control/data links CURRENT licence-exempt framework Ofcom Not a complete connectivity model for scaled BVLOS
Mobile / cellular Command-and-control and data connectivity CURRENT WITH CONDITIONS Ofcom Relevant network operator agreement is required; CAA aviation rules remain separate
Satellite Longer-distance communications option CURRENT WITH CONDITIONS Ofcom Network/equipment permissions and operational constraints still apply
978 MHz UAT Airborne safety / traffic-awareness equipment CURRENT Ofcom / CAA Safety function, not a general broadband command link
453–462.5 MHz Drone control links PROPOSED Ofcom 2026 consultation Final Ofcom decision not located as of 1 Oct 2026
5030–5091 MHz, preferred 5040–5060 MHz Drone control links PROPOSED Ofcom 2026 consultation Final Ofcom decision not located as of 1 Oct 2026

Why this table matters: a reader can easily confuse "Ofcom is consulting on a band" with "operators can use that band today". They are not the same thing.

What about 978 MHz?

In March 2025, Ofcom and the CAA made 978 MHz available for airborne transmission by UAS using Universal Access Transceiver (UAT) equipment.

That change is useful context because it shows how the UK is already adding specialised spectrum capabilities for drone safety and airspace integration.

But it should not be described as a replacement for a primary command-and-control network.

Its role is different: helping support airborne awareness and safety functions.

This is another reason the word "connectivity" needs to be broader than "the link between the controller and the drone".

Where satellite connectivity fits

Satellite connectivity is sometimes presented as the obvious answer to mobile-network gaps.

It can be part of the answer, but it is not a universal shortcut to BVLOS.

Ofcom's existing UAS Operator Radio framework permits specified satellite technologies, subject to the relevant permissions. Its guidance also makes clear that airborne use can depend on the satellite network and frequency involved.

Satellite may be especially relevant where terrestrial coverage is sparse, but the full operating system still has to account for:

  • equipment and service compatibility;
  • applicable spectrum permissions;
  • aviation authorisation;
  • mission safety;
  • the wider command-and-control architecture.

So "satellite-connected" and "legally ready for routine BVLOS" are not interchangeable descriptions.

The bigger picture: BVLOS is becoming infrastructure policy

The UK's BVLOS roadmap is not only about drones.

It is about how drones fit into national airspace, telecommunications and spectrum policy.

The CAA's Future of Flight BVLOS roadmap says it is working toward routine UK BVLOS operations by 2027.

That involves more than communications. The CAA highlights the need to integrate UAS safely into airspace while protecting other airspace users and people on the ground.

The communications layer therefore sits beside other issues such as:

  • Detect and Avoid;
  • electronic conspicuity and traffic awareness;
  • airspace integration;
  • operational authorisation;
  • remote pilot competency;
  • safety cases;
  • scalable operating models.

Connectivity is one enabling layer in a much larger system.

But without dependable connectivity, many of the commercial use cases associated with BVLOS — long-distance inspection, logistics, emergency response, infrastructure monitoring and remote operations — become much harder to scale.

A simple way to think about a resilient BVLOS connectivity stack

A conceptual UK BVLOS system might look like this:

Primary command-and-control link ↓ Backup / alternative communications path ↓ Aircraft position and safety-awareness data ↓ Operational telemetry / payload data ↓ Operator and network monitoring ↓ CAA operational authorisation + Ofcom spectrum permissions

That is not a prescription for how every operator should engineer a BVLOS system.

It is a way to understand why the issue cannot be reduced to one advertised radio range or one mobile-network logo.

What is still unresolved

Several important questions remain open.

Will Ofcom adopt the 2026 additional-band proposals?

We do not yet have a final decision in the sources checked for this article.

Which technologies will dominate UK BVLOS?

The likely answer may be a mix of cellular, specialised spectrum and satellite rather than one winner, but the balance will depend on operations, coverage, regulation and economics.

How will communications requirements interact with future CAA rules?

The CAA's roadmap continues to evolve toward routine operations. Communications is one part of the safety architecture, not a separate substitute for it.

How quickly will commercial deployments scale?

That will depend on more than technology. Licensing, operational approvals, airspace integration, business cases and reliable service coverage all matter.

These are exactly the kinds of areas where a source-backed, regularly updated resource is more useful than a one-off news story.

Frequently asked questions

Does BVLOS simply mean using 4G or 5G?

No.

Cellular networks can support BVLOS command-and-control and data links, and the UK Government is explicitly encouraging work on cellular drone operations. But BVLOS also involves aviation authorisation, operational safety, coverage, redundancy and airspace integration.

A long advertised control range does not itself authorise BVLOS flying.

The CAA says BVLOS operations require the appropriate Operational Authorisation.

Does an Ofcom UAS Operator Radio licence authorise the flight?

No.

It authorises spectrum use under the licence conditions. CAA aviation and safety requirements still apply.

Ofcom specifically notes that BVLOS use cases may rely on mobile networks for primary command-and-control but may require backup spectrum where mobile coverage has gaps.

Are 450 MHz and 5030–5091 MHz already approved for the new 2026 drone proposals?

Not according to the evidence checked for this article.

Ofcom's July 2026 page presents them as consultation proposals. The stated response deadline was 30 September 2026. As of 1 October 2026, Ofcom's official page still showed Status: Open and we had not located a final decision; the post-deadline status is therefore treated as UNKNOWN.

What is the CAA's current BVLOS target?

The CAA says its roadmap is intended to establish routine BVLOS operations in the UK by 2027.

What this means for drone buyers

For most people buying a consumer drone, the practical rule remains simple:

Do not treat an advertised control range as permission to fly beyond visual line of sight.

A drone with a multi-kilometre radio specification may be technically capable of maintaining a connection at a long distance under certain conditions. That does not remove VLOS requirements or create a BVLOS authorisation.

If you are new to UK flying, start with our UK Drone Law Change 2026 guide and the CAA's own current guidance.

For commercial and advanced operators, the more useful question is no longer "What is the maximum range?"

It is:

What combination of communications, safety systems, network coverage, spectrum permission and aviation authorisation makes the operation resilient enough to scale?

That is where the UK's BVLOS debate is heading.
