In short: A vertiport is a small aerodrome with the data load of a large one, and most of the UK sites now being planned sit on business parks, heliports and brownfield land with no airfield network to extend. Vertiport connectivity is the unglamorous prerequisite under the CAA's 2028 timeline, and it needs specifying now, while the concrete is still being poured.
Key Takeaways
- 2028 is the date to design against — The CAA's eVTOL Delivery Model targets commercial passenger operations by the end of 2028, so the ground infrastructure specified during 2026 is the infrastructure that carries the first fare-paying passengers.
- Charging is a coordination problem before it is an electrical one — An eVTOL turning in under fifteen minutes needs high-rate charging scheduled across stands against a fixed grid connection, which means live state-of-charge telemetry from every aircraft and charger on the pad.
- Most vertiports are not airports — Bicester Motion, city heliports and rooftop sites have no ops room, no airfield fibre ring and no existing wireless estate, so the network is a greenfield build rather than an extension.
In a nutshell
What is a vertiport, and what does it actually need to connect?
A vertiport is a landing site built for electric vertical take-off and landing aircraft: a final approach and take-off area, one or more parking stands, charging, passenger processing, and enough surveillance and weather instrumentation to decide whether an approach is safe. The CAA describes vertiports as sites for the arrival, departure and surface movement of VTOL aircraft, and it has been consulting since January 2024 on what additional safety requirements existing aerodromes need before they can host them, covering operating area design, obstacle limitation surfaces, visual aids and rescue and firefighting cover.
The connectivity requirement falls into four groups. Aircraft charging, which needs continuous telemetry from chargers and aircraft to schedule energy against a grid connection. Operational scheduling, which needs to know where every aircraft is, how much charge it has and which stand is free. Situational awareness, which means weather sensors, cameras and aircraft tracking feeding a decision that has a few seconds to be made. And passenger processing, which is security screening, identity, baggage and accessibility, all of which the CAA has already written consumer principles for in CAP 2539, including explicit obligations on passengers with reduced mobility.
None of that is exotic. What makes it awkward is where it has to happen: an open pad with a large metal object on it, moving ground vehicles, a rotor downwash field that reshapes the local RF environment several times an hour, and in many cases no building to hang access points from.
Where are the UK's vertiports right now?
Bicester Motion in Oxfordshire is the site to know about. Skyports Infrastructure has completed a vertiport there, under construction since late 2024 and now operationally complete, backed by the Future Flight Challenge and due to begin flight testing during 2026. At its preview, Skyports demonstrated passenger processing, vertiport automation for both aircraft and passengers, its Remote Management and Scheduling System, and situational awareness tooling including weather sensors and real-time aircraft tracking. Every one of those is a data product that needs a network under it.
Vertical Aerospace, based in Bristol, has announced plans with Skyports and Bristow to launch the UK's first electric air taxi network using the VX4, and welcomed the CAA's eVTOL Delivery Model in September 2025 as the regulatory route to UK operations by the end of 2028. Before Bicester there was Urban-Air Port's Air-One in Coventry, which opened in April 2022 as a demonstrator and proved that a vertiport could be dropped onto a city centre car park, which was the point.
Government policy has been consistent about the timetable. The Future of Flight action plan set out a first piloted flying taxi flight by 2026, regular services by 2028, and demonstrations of autonomous passenger flight by 2030. Whether those dates slip by a year or two matters less than the planning consequence, which is that sites are being designed and built now, and the network decisions taken during design are the ones an operator lives with for a decade.
Why is charging the hardest connectivity problem at a vertiport?
Because the commercial model depends on turnaround time, and turnaround time depends on charging at a rate the grid connection cannot sustain for every stand at once.
An eVTOL carrying four or five passengers on a thirty-minute hop needs to recharge enough energy between rotations to fly the next leg with reserves. Operators talk about turnarounds in the ten to fifteen minute range, which implies charge rates in the hundreds of kilowatts per stand. Put four stands on one site and the connected load runs into the megawatts. Very few of the locations that make commercial sense for air taxis, which are city fringes, transport interchanges and business parks, have a spare megawatt-class connection sitting idle.
The answer everywhere else in electric transport has been load management, and it works the same way here. You schedule charging against the flight programme, draw on battery storage for peaks, and hold aircraft at a lower state of charge when the next rotation is short. That only works if the site knows, continuously and accurately, what each charger is delivering, what each aircraft's state of charge is, and what the next three departures need. Lose that telemetry for ninety seconds during a wave and the scheduler is guessing.
This is the same pattern we described in electric ground support equipment on the apron, and the lesson transfers directly. The electrical engineering is well understood. The reason e-GSE charging projects underperform is almost always that the data layer was assumed rather than designed.
What else has to be on the vertiport network?
Weather instrumentation comes first. Vertiport operations are more weather-limited than conventional aviation, because eVTOL performance in the hover is sensitive to crosswind, gusts and the downwash and outwash behaviour the CAA has been studying in CAP 2576. A vertiport therefore carries more instrumentation than a heliport of equivalent size: anemometers at multiple heights, visibility and cloud base sensors, sometimes surface condition monitoring. Those feed a go or no-go call that has to reach an inbound aircraft and a scheduling system in near real time.
Surveillance is the next layer. Sites are expected to track aircraft on approach and on the surface, which means cameras, and at larger sites radar or cooperative surveillance feeds. Camera uplink is the load that breaks improvised networks: a handful of high-resolution streams from pad-edge poles is a sustained uplink requirement, not a burst, and it has to hold while the pad is occupied by a large metal aircraft sitting between the camera and the receiver.
After that comes the ground operation itself. Passenger processing and security screening, which at a small site may be a handful of tablets but still needs to work on the apron side as well as landside. Firefighting and rescue cover, which the CAA consultation specifically raised for aerodromes adding VTOL operations. Ground vehicles, which at an all-electric site are themselves charging assets with telemetry. Accessibility equipment and staff comms. And the maintenance layer, because an eVTOL is a new type with a heavy inspection regime and engineers working from tablets against electronic task cards, the same problem we wrote about in aircraft maintenance hangars.
Does the aircraft itself fly on the vertiport network?
No. The aircraft's own links run on aeronautical spectrum, not on the site operator's network.
Command and control links for remotely piloted or autonomous aircraft, and the communication, navigation and surveillance services that underpin air traffic management, are aeronautical safety services. They use protected aeronautical spectrum, they are regulated as safety-of-life services, and they will not be carried over a site operator's private 5G network. The CAA's work on the eVTOL delivery model addresses that domain separately, and the industry is still working through what the C2 link architecture looks like for autonomous operation in the 2030s.
What a private network at a vertiport serves is the ground domain: charging, scheduling, weather, cameras, passenger systems, vehicles, staff and maintenance. That distinction matters commercially, because it means the business case for the network stands on operational efficiency and passenger throughput rather than on flight safety, and it can be built and paid for by the site operator without entering a certification programme.
Why not Wi-Fi, or a public 5G SIM in everything?
For a single-pad test site doing a handful of movements a week, a good Wi-Fi install and a bonded 4G router is genuinely sufficient, and we would say so to anyone asking. The honest threshold is where a vertiport starts running a schedule.
Wi-Fi's problem at a vertiport is geometry. The site is mostly open ground with one enormous reflective object that moves, and coverage from building-mounted access points across a pad gets blocked by the aircraft itself at exactly the moment the aircraft is the thing you need data from and about. Unlicensed spectrum on a city-fringe site also means sharing with whatever else is nearby. Camera uplink and charger telemetry are the two loads least tolerant of contention, and they are the two that define the site.
Public mobile has a different failure mode. Coverage at Bicester Motion, a former airfield in rural Oxfordshire, is whatever the operators have built for the surrounding villages, and coverage on a rooftop or riverside heliport is shaped by the buildings around it. More to the point, there is no service level, no control over what happens during an event in the city, and no way to prioritise a charger telemetry stream over a passenger's video call. For a site whose entire operating model rests on a schedule, renting connectivity with no contractual grip on it is a strange place to economise.
A private 5G network sized for a vertiport is not a large project. Ofcom's Shared Access framework covers n77, 3.8 to 4.2 GHz, and a Low Power licence costs £80 per 10 MHz channel per site per year, granted for a defined location. Two or three radios cover a pad, the stands, the charging area and a small terminal building with planned, predictable coverage, on spectrum nobody else is using, with quality of service the operator sets. Set that cost against a cancelled rotation.
What should a vertiport operator specify now?
Four things, while the site is still on paper.
Put conduit and power to the pad edge for radio positions during groundworks, because retrofitting a mast base into a finished FATO surround is expensive and disruptive. Specify the charger and the aircraft interface to expose telemetry over IP on an open protocol, rather than accepting a vendor's closed app, since the scheduling system will need that data from day one. Size the backhaul for sustained camera uplink rather than average office traffic, and get a second path if the site has any commercial schedule at all. And treat spectrum as a planning item with a lead time, not an afterthought.
Bicester begins flight testing during 2026. If the CAA's end-of-2028 target for commercial passenger operations holds, the sites that carry those first passengers are being designed this year. We are happy to look at a site plan and tell an operator what the radio positions and backhaul need to be; that conversation takes an hour and is considerably cheaper before the concrete goes down.
