Yes, you can get reliable, high-speed connectivity on a site with absolutely no existing infrastructure or mains power. This is one of the most common challenges we solve for events across the North East, and the short answer is that a combination of mobile bonded internet, satellite links, generator power, and purpose-built temporary network infrastructure makes it entirely achievable. The honest caveat is that it requires proper planning, the right equipment, and an experienced team who understand the variables — but it is absolutely not a barrier to running a professional event.
Key Takeaways
- Temporary event WiFi does not require any existing cabling, fibre, or mains power on site
- Mobile bonded internet (combining multiple 4G/5G SIM cards) is the most common solution for green-field sites
- Satellite connectivity (including Starlink) provides a reliable backup or primary link where cellular signal is poor
- Generator power or battery systems can run all networking equipment without any mains supply
- Proper site surveys, channel planning, and load testing are what separate reliable event WiFi from unreliable consumer kit
Why Sites With No Infrastructure Are More Common Than You Think
A large proportion of the events we work on take place in fields, temporary structures, rural estates, beachfronts, and historic venues where fibre or even basic cabling simply does not exist. Festivals, agricultural shows, outdoor corporate days, motorsport events, and pop-up markets all share the same challenge: the site is essentially a blank canvas with no data or power provision built in.
This is not a niche problem. It is the default condition for a huge number of events, and treating it as an obstacle rather than something to plan around is where organisers run into trouble.
How We Deliver Internet on a Site With No Fixed Connection
Mobile Bonded Internet
Our primary tool for sites without fixed connectivity is bonded mobile internet. This involves combining multiple 4G and 5G SIM cards from different networks — typically EE, Vodafone, Three, and O2 — through a single bonding router that treats them as one unified pipe. Rather than relying on a single network that might be congested or have poor signal, bonding spreads the load and provides resilience.
In practice, a well-configured bonded unit on a site with reasonable 4G coverage can deliver 100–300 Mbps of usable throughput — enough to support hundreds of simultaneous users, live streaming, card payment systems, and back-office operations running concurrently.
Starlink and Satellite Backup
Where cellular signal is genuinely poor — remote rural sites, valley locations, coastal areas with limited tower coverage — Starlink has become a practical and cost-effective solution. Latency on Starlink’s low-earth-orbit network sits around 20–40ms, which is comfortably low enough for video calls, live streaming, and EPOS systems.
We typically run Starlink alongside a bonded mobile unit so that if one link degrades, the other maintains service. Redundancy is not a luxury on live events; it is the only sensible approach.
Building the Network From Scratch
Getting an internet connection to a site is only half the job. That connection then needs to be distributed reliably across the entire footprint — which might be a 10-acre showground, a temporary marquee complex, or a multi-stage festival site.
We design and deploy temporary WiFi networks using professional-grade access points (typically Ubiquiti or similar enterprise hardware), running structured cabling or wireless backhaul between zones. Every network is configured with proper SSID separation, bandwidth management, and firewall rules. We set upload and download limits per user where required, prioritise traffic for things like live streaming and payment terminals, and keep staff and public networks entirely separate.
This is not a case of plugging in a consumer router and hoping for the best. Proper channel planning, access point placement, and load testing before doors open is what makes the difference between WiFi that holds up under pressure and WiFi that fails the moment 300 people walk through the gate.
What About Power?
All of the above equipment needs power, and on a site with no mains supply that means generators or battery storage systems.
For smaller deployments, a single diesel generator or a high-capacity lithium battery unit can run all networking equipment for a full day with room to spare. For larger events, we coordinate with power suppliers to ensure dedicated, clean power feeds for AV and IT infrastructure — shared generator supplies with lighting rigs and catering equipment can introduce interference that affects sensitive electronics.
Power planning is part of every connectivity brief we take on. It is not an afterthought.
What Can Go Wrong (and How We Prevent It)
Being transparent about the challenges is part of doing this properly. The main risks on an infrastructure-free site are:
- Cellular congestion: if 5,000 people arrive on site and everyone’s phone starts hammering the local towers, the available bandwidth for bonded mobile drops. We mitigate this with higher-gain directional antennas pointed at specific sectors and, where possible, running Starlink as the primary link.
- Physical obstructions: metal structures, dense crowds, and terrain all affect wireless performance. A site survey — ideally in person — lets us identify dead zones before they become a problem during the event.
- Weather: outdoor cabling and access points need to be rated for the conditions. We use IP65-rated or better hardware and properly weatherproofed enclosures.
- Power fluctuations: generator power can be noisy. We use UPS units and power conditioners on sensitive networking equipment.
None of these are reasons to say connectivity is impossible. They are reasons to plan properly.
Why Experience Matters
We have deployed temporary connectivity solutions on sites ranging from small corporate days with 50 attendees to multi-stage outdoor festivals. The technical kit is only part of the answer — knowing how to configure it, where to place it, and what to do when something unexpected happens on the day is what actually keeps an event running.
If you are planning an event on a site with no existing infrastructure or power and you need reliable connectivity for attendees, live streaming, EPOS, or production, dwmedia can survey, design, and deliver the whole solution.

Frequently asked questions
Can you get WiFi at an outdoor event with no mains power?
Yes. WiFi access points and bonded internet routers can be powered by generators or battery storage systems, meaning no mains supply is needed. dwmedia plans power provision as part of every temporary connectivity deployment.
What is bonded mobile internet and why is it used for events?
Bonded mobile internet combines multiple SIM cards from different networks into a single connection, increasing throughput and resilience. It is the most practical solution for sites without fixed fibre or broadband, delivering speeds of 100–300 Mbps under good conditions.
Is Starlink suitable for live event connectivity?
Yes, Starlink is well-suited to events where cellular coverage is poor, with typical latency of 20–40ms — low enough for live streaming, video calls, and payment systems. It works best when paired with a bonded mobile unit as a backup or redundant link.
How many people can temporary event WiFi support?
A well-designed temporary network using enterprise access points and a bonded mobile or Starlink connection can comfortably support hundreds of simultaneous users. The key factors are proper access point placement, bandwidth management, and separating staff and public traffic.
Do you need to visit the site before setting up event WiFi?
A site survey is strongly recommended, particularly for sites with no existing infrastructure. It allows the team to identify cellular signal strength, physical obstructions, power options, and the best positions for access points before the event day.
