5G & Alternative Event Internet: Wi-Fi/5G Setup, VoWiFi, and Stratospheric Internet—What’s Realistic?

Whether it’s a trade show, conference, roadshow, training session, promotional event, or temporary project site: without a stable internet connection, many events can only function to a limited extent. Digital admission checks, cloud-based presentations, mobile point-of-sale systems, video conferences, livestreams, and apps for attendees all rely on a reliable connection. At the same time, events create conditions that are particularly challenging for wireless networks. Many people access the network simultaneously in a confined space, hall walls attenuate cellular signals, and public 5G networks can be heavily congested during peak hours of all times.

As of 2026, there are several realistic options for temporary event internet. These include existing landline connections, public 4G and 5G networks, professionally planned Wi-Fi, bundled cellular connections, local 5G networks, and satellite-based access. Stratospheric internet is increasingly being tested, but it is not yet a standard solution that can be routinely planned for typical events in Germany.

Therefore, what matters is not which technology achieves the highest speed on paper. What matters is which overall system works reliably at the event venue and is compatible with the smartphones, tablets, laptops, displays, and applications being used.

Event-Internet is more than just a fast router

A stable connection consists of several layers. First, an Internet connection is required. This so-called backhaul can be provided via fiber optics, an existing Ethernet connection, 5G, LTE, or a satellite system. A router then distributes the connection to the local network. Access points provide Wi-Fi to end devices, while switches connect wired systems such as control rooms, streaming encoders, or stationary check-in terminals.

Overall performance is limited by the weakest link in this chain. A modern Wi-Fi 7 access point cannot compensate for a lack of internet bandwidth. Conversely, high-performance internet access is of little help if a single Wi-Fi router is expected to serve several hundred devices. Power supply, cabling, antenna placement, device configuration, and ongoing monitoring are also part of the setup.

Before making a selection, it is therefore important to determine which processes are business-critical. A failure of the guest Wi-Fi is inconvenient. However, an outage affecting admission control, the box office, event management, or the livestream can disrupt the entire event. These applications should be planned separately and, if possible, secured via independent connections.

Public 5G: Quick to Set Up, but Not Fully Controllable

For many small and medium-sized events, public 5G is the most practical starting point. A high-performance 5G router with a compatible SIM card can provide Internet access in a short amount of time. This is suitable for temporary offices, trade show booths, training rooms, promotional areas, and mobile project teams, among other things.

However, the 5G icon on a device says little about the actual quality of service. Speed and stability depend on the frequency band, distance to the cell tower, signal attenuation caused by buildings, antenna alignment, network load, and the user’s service plan. At a well-attended event, numerous smartphones share the capacity of the surrounding cell towers. As a result, a connection that works quickly in the morning may respond significantly more slowly during the main event.

Upload speeds are particularly often underestimated. Websites and downloads primarily require bandwidth in the download direction. Live streams, cloud backups, video calls, media uploads, and remote access, on the other hand, generate continuous upload traffic. For these applications, a high download speed alone is not sufficient.

What Sets a Professional 5G Setup Apart

Previous measurements taken at the specific location and, if possible, at a comparable time of day
Routers with compatible cellular modems, Gigabit Ethernet, and ports for external antennas
SIM cards from different network operators, so that not all connections depend on the same cell
Separate networks for production, staff, exhibitors, point-of-sale systems, and guests
Defined bandwidth rules to prevent individual downloads from monopolizing the entire connection
Monitoring of utilization, signal quality, data volume, and connection changes
Uninterruptible Power Supply for Routers, Switches, and Access Points

External antennas can make a significant difference, especially in halls and shielded buildings. This means the router does not have to be placed directly next to a window. Instead, the antenna can be positioned at a suitable location, and the connection can be routed to the event area via a network cable.

Failover and bonding are not the same thing

A multi-WAN router allows you to connect multiple Internet connections at the same time. This could be a combination of various 5G connections, an existing landline connection, and a satellite terminal. It is important to distinguish between load balancing, automatic failover, and true bonding.

With automatic failover, a backup connection is activated if the primary connection fails. Video conferences or VPN sessions that are already in progress may be briefly interrupted. Load balancing distributes various connections or users across multiple access points. This increases the overall capacity, but not necessarily the speed of a single data transfer.

True bonding splits data streams and recombines them at a remote location. This can better handle connection changes and combine multiple upload paths. It requires suitable routers, a bonding service, and careful configuration. For livestreams or important hybrid events, this extra effort can be worthwhile.

Wi-Fi Determines the User Experience

Internet access ends at the router, but for most visitors, the connection doesn’t begin until they connect to the Wi-Fi. At events, many devices need to be connected simultaneously. A long range isn’t necessarily an advantage in this situation. While a single access point with high transmission power may have a wide coverage area, it quickly becomes a bottleneck.

In areas with a high density of devices, it is usually more effective to use several strategically placed access points with coordinated transmission power. This results in smaller radio cells and allows frequencies to be reused more efficiently. Where possible, access points should be connected via Ethernet. A wireless mesh can help in challenging locations, but it itself consumes radio capacity and should not be considered a universal solution without proper planning. For more information on radio cells, guest access, and network architecture, see the article on Wi-Fi at events.

Wi-Fi 6 remains a powerful foundation for many event scenarios. Wi-Fi 6E expands its use to include the 6-GHz band, which is often less congested. However, the higher frequency is more heavily attenuated by walls, structures, and people. Wi-Fi 7 offers additional capabilities such as multi-link operation, wider channels, and more efficient spectrum utilization. The practical benefit, however, depends on whether access points, network architecture, and end devices actually support these features.

Backward compatibility is important for mixed device fleets. Older smartphones, scanners, or point-of-sale terminals may only support 2.4 or 5 GHz. The 2.4-GHz band offers greater range but has fewer non-overlapping channels and is often heavily congested. A well-designed system therefore uses multiple frequency bands and assigns appropriate radio cells to the devices.

VoWiFi: Making Calls Over the Event Wi-Fi Network

VoWiFi, often referred to as Wi-Fi calling, allows users to make mobile phone calls over a Wi-Fi connection. The smartphone connects to the mobile carrier’s telephony platform via the Internet. The phone number and mobile plan generally remain the same. This is particularly useful when there is little to no cellular reception inside a building, but a high-performance Wi-Fi network is available.

At an event, VoWiFi can improve the reachability of staff, exhibitors, and project teams. However, this feature requires that mobile carriers, service plans, and devices support it and are properly configured. In addition, the Wi-Fi network must offer low packet loss, sufficiently low latency, and stable handoffs between access points.

Switching between Wi-Fi and cellular networks, or between poorly coordinated access points, can be problematic. Not every combination of device, provider, and network handles such transitions the same way. Therefore, the intended smartphone models and SIM cards should be tested before use. A successful internet speed test does not necessarily guarantee good voice quality.

Emergency calls also deserve special attention. Their handling over Wi-Fi depends on the device, mobile carrier, configuration, location information, and regulatory requirements. VoWiFi should therefore not be planned as the sole communication solution for security services or emergency response organizations. For critical teams, additional cellular devices, radio technology, or professionally managed push-to-talk solutions may be appropriate.

Private 5G and campus networks for controlled applications

A private 5G network can be useful when many controlled devices with defined performance and security requirements need to be connected. In Germany, frequencies in the 3.7 to 3.8 GHz range, among others, are available for local campus networks. Such networks can be operated independently of the load on public cellular networks.

Possible applications include large-scale production events, industrial demonstrations, extensive media productions, temporary logistics areas, or projects involving numerous cameras, scanners, and control systems. Devices can be authenticated using appropriate SIM or eSIM profiles. Local data traffic can be processed within the organization’s own infrastructure without first routing every data stream through the public Internet.

For a one-time event planned on short notice, however, a private 5G network is not automatically the most cost-effective or fastest option. Issues related to frequencies, radio planning, the core network, compatible devices, SIM management, and operations all require advance preparation. Not every off-the-shelf smartphone supports all the required frequencies and network profiles. Campus 5G is therefore particularly appealing for larger, recurring, or especially demanding projects.

Satellite Internet as an Alternative and Fallback Option

Modern satellite systems in low Earth orbit offer significantly lower latency than traditional geostationary satellite connections. For open-air events, construction sites, remote venues, and temporary locations without a suitable landline connection, such a system can provide high-performance Internet access.

A satellite terminal requires a clear view of the sky. Trees, building roofs, facades, trusses, and other obstacles can cause brief interruptions. The terminal is therefore typically installed outdoors and connected to the local network via Ethernet. Secure mounting, an adequate power supply, and protection of the cable routes must be part of the planning.

Satellite internet is also suitable as an independent fallback option for 5G. Such a combination reduces the risk that congestion or disruption of a local cellular network will affect all applications simultaneously. However, the entire system is only fully independent if the routers, power supply, cabling, and network components are also designed with redundancy.

Stratospheric Internet: fascinating, but not yet a standard solution for events in 2026

Stratospheric platforms are known as High Altitude Platform Stations. Unmanned aircraft or balloon-like platforms carry cellular and data communication technology at an altitude of about 20 kilometers. They are thus significantly closer to Earth than satellites. A single platform can cover a large area and function, from a technical standpoint, like a cellular base station in the sky.

By 2026, the technology had reached an interesting stage of development. International providers are conducting field trials and pre-commercial programs. Among other things, they are testing direct connections to mobile devices, disaster communication, and service provision to hard-to-reach regions. This requires the coordination of platform operations, spectrum usage, aviation law, ground stations, and integration into mobile networks.

When planning a trade show or corporate event in Germany, however, stratospheric internet should not currently be factored into plans as a service that can be ordered as usual. It is not a system that an event organizer can simply set up at the venue like a 5G router. Service is provided on a large scale by platform and network operators and depends on regional approvals and available services.

In the medium term, stratospheric platforms could complement terrestrial networks and satellite systems. Areas with damaged infrastructure, large-scale outdoor events, and temporary capacity expansions are of particular interest. For current event projects, fixed-line networks, public 5G, private 5G, professional Wi-Fi, and LEO satellite access remain the more realistic options.

Stratospheric Internet	Potential for widespread coverage and emergency response	Wide coverage area, potentially low latency	Not yet a regular standard option for typical events in Germany in 2026

The most realistic solution is usually a hybrid setup

For business-critical events, it is not a single technology that is crucial, but rather a combination of several appropriately separated components. An existing Ethernet connection can serve as the primary connection. Two 5G connections from different network providers provide additional capacity and failover protection. At remote locations, a satellite terminal can provide another independent route.

On the local network, production, HR, VoWiFi, payment systems, and guests should be assigned separate SSIDs or VLANs. Business-critical applications take priority. The guest Wi-Fi can be subject to bandwidth limits to ensure that large downloads or automatic cloud backups do not interfere with access control.

Security measures include up-to-date firmware, strong login credentials, appropriate Wi-Fi encryption, firewall rules, and, if necessary, VPN connections to corporate systems. Additional recommendations regarding risky hotspot and smartphone settings can be found in the guide on secure Wi-Fi while traveling and at events. Temporarily provided smartphones, tablets, and laptops can be preconfigured. This allows apps, user accounts, Wi-Fi profiles, SIM cards, and project-specific settings to be prepared before shipment. For such requirements, get-IT-easy can incorporate the appropriate configuration of the rental devices into the project planning.

What information is needed for planning

Reliable equipment planning starts with specific project information. This includes the event location, whether it’s indoors or outdoors, the setup day, the duration, the expected number of users, the number of devices, and the applications being used. For livestreams, the required resolution and number of concurrent streams should be known. For VoWiFi, relevant factors include smartphone models, mobile carriers, and planned areas of movement.

The floor plan also affects the technology. Steel, glass, concrete, fire doors, and temporary exhibition walls alter radio wave propagation. For larger projects, the setup should be tested under realistic conditions before the event begins. This includes not only a speed test but also checking Wi-Fi roaming, upload speeds, latency, packet loss, and automatic switching to backup connections.

get-IT-easy helps companies select and arrange rental agreements for the right smartphones, tablets, laptops, routers, SIM cards, and accessories for their specific projects. Upon request, devices can be preconfigured and prepared for their intended use. The specific scope depends on the quantity, rental period, location of use, desired features, delivery method, and additional services. A customized quote is prepared based on these factors. The checklist for hardware rollouts at events also provides a structured overview of planning, configuration, logistics, and return procedures.

FAQ on 5G and Event Internet

Is a single 5G router enough for an event?

For a small trade show booth or a small project team, a single router may be sufficient. If there are many users, point-of-sale systems, live streams, or critical cloud applications, at least one independent backup connection should be provided. In addition, the Wi-Fi network must be designed to handle the number of devices. For smaller LTE-based scenarios, for example, a 4G/LTE battery-powered router could be considered as a mobile component; its specific suitability and availability will be evaluated on a project-by-project basis.

Can public 5G replace a dedicated Internet connection?

This is often possible for temporary deployments. However, the quality depends on the location, network provider, and network load. For business-critical processes, it is recommended to perform a preliminary test and establish a second connection via a different access method.

Does VoWiFi work with every smartphone?

No. The device, operating system, mobile carrier, and service plan must all support Wi-Fi calling. In addition, the feature must be enabled and provisioned by the carrier. Before rolling out the service on a large scale, the intended device combinations should be tested.

Is Wi-Fi 7 necessary for events?

Wi-Fi 7 can offer advantages in high-traffic environments and with modern devices. It is not necessary in every scenario. A carefully planned Wi-Fi 6 or Wi-Fi 6E network can reliably support many events. Placement, cabling, channel planning, and available internet capacity are often more important than the latest Wi-Fi generation.

Is satellite internet better than 5G?

Both technologies serve different purposes. 5G is often easy to set up and does not require a clear line of sight to the sky. Satellite internet can be useful in remote locations or as an independent backup. A hybrid setup combines the advantages of both access methods.

Can we already request stratospheric internet for an event?

As a standard temporary internet solution for events in Germany, it cannot yet be factored into plans for 2026. The technology is currently in pre-commercial programs and regional trials. For current projects, 5G, Wi-Fi, landlines, private mobile networks, and LEO satellite systems are more realistic options.

Conclusion: Reliable event connectivity is achieved through planning and redundancy

In 2026, 5G will be a key component of temporary event internet, but not a one-size-fits-all solution for every location. Professional Wi-Fi, independent backup connections, suitable devices, and clear prioritization of applications determine whether the system will function even under heavy load. VoWiFi can improve coverage inside buildings, but it must be tested with the intended smartphones and mobile data plans.

Satellite internet complements local networks, particularly at remote event venues and as an additional backup option. Private 5G is suitable for larger or recurring projects with controlled device fleets. Stratospheric platforms demonstrate the potential future of connectivity, but for typical event planning, they currently still fall into the category of future technology.

If you need mobile devices, routers, SIM cards, and accessories for only a limited period of time, you can use the rental service offered by get-IT-easy on a project-by-project basis. By providing details on the number of units, rental period, event location, applications, and configuration requirements, you can plan a suitable setup and submit a customized request.
