There's a conversation that happens, in some form, before almost every corporate live stream we deliver at an external venue. It goes something like this:
"We've spoken to the venue and they've confirmed the internet is fine."
It's said with confidence, and that confidence is understandable, since the venue said so. What the venue usually means, though, is that the internet is fine for the things the venue normally uses it for: guests browsing on their phones, delegates checking email, the occasional video call. A professional live broadcast demands something rather different of an internet connection, and "fine" almost never covers it.
What a Live Broadcast Actually Needs
A live stream needs more than an internet connection. It needs a stable, guaranteed upload speed, sustained continuously throughout the event, with no drops, no congestion, and no sharing with other users whose activity you can't control.
Most venue broadband connections are shared. The bandwidth available to your broadcast at any given moment depends on what else is happening on the network at the same time: the delegate who's uploading a presentation, the breakout room running its own video call, the catering team streaming music, and the forty other people in the building doing things you'll never know about.
Under quiet conditions, this might not matter. Under the conditions of a busy event, which is exactly when you need the connection most, it often does, and the stream can stutter or lose picture quality as a result. It's a risk that's easily avoided with the right planning, which is exactly what we cover below.
We saw this first-hand at a conference centre that had assured us their dedicated business broadband was more than sufficient for our requirements. On paper, the speeds looked adequate. In practice, the connection was shared across the building's infrastructure in ways that only became clear once we were on site running our own line tests. Because we'd arrived with a backup connection ready to go, switching over took minutes and the broadcast went ahead without a hitch. It's a good example of why we never rely on a single connection, however confident the assurances from the venue.
Why Venues Get This Wrong
Venue staff aren't broadcast engineers. When they tell you the internet is fine, they're answering a question about whether guests can get online, not whether the connection can sustain a stable 10-20 Mbps upload throughout a live broadcast while the rest of the building is in full use.
This isn't a criticism of venues. It's a structural mismatch: the question asked ("is your internet okay for live streaming?") sounds simple, and the answer given is genuinely well-intentioned. But the technical requirements of a professional broadcast aren't something a venue coordinator is equipped to verify, and the consequences of getting it wrong fall on the event rather than the venue.
Even venues with dedicated business broadband can present problems. A single broadband connection, however fast, is still a single point of failure. If it goes down, whether through a fault, an outage, or unexpected congestion, there's nothing to fall back on unless a backup has already been planned.
The Solutions
Line testing on arrival. Before anything else, we test the available connection: upload speed, download speed, latency, and stability under load. A speed test number isn't enough; we need to know the connection can sustain the required upload over time, not just in a momentary burst.
Hardwired ethernet where possible. Given the choice, we'll always prefer a hardwired ethernet connection over Wi-Fi at our technical control position. It removes local wireless interference and contention from the equation and gives us the most stable link between our equipment and the venue's network. It's worth noting, though, that ethernet still typically shares the same outside-world internet connection as the venue's Wi-Fi, so it doesn't on its own solve problems with the building's overall bandwidth. It's a sensible first step, and one we combine with the other measures below rather than relying on alone. Where we're working from a client's own office rather than an external venue, it's also worth checking early whether that ethernet port sits behind the corporate firewall. A live broadcast often needs a "raw" internet connection that bypasses internal firewalls, or the IT team may need to adjust outbound firewall rules in advance to allow the streaming traffic through.
Bonded mobile connectivity. Where the venue connection isn't adequate, or simply as a backup, we can use bonded mobile data: multiple SIM cards from different networks combined into a single connection. Because it uses multiple independent networks simultaneously, a problem with one doesn't bring down the broadcast. This is the most common solution for events where venue connectivity is uncertain.
Satellite connectivity (Starlink). For venues with poor mobile signal, or outdoor and rural locations where fixed broadband isn't an option, Starlink gives us a connection that's entirely independent of the venue's own network. It's a strong choice as a primary connection in hard-to-reach locations, or as an additional layer of redundancy alongside bonded mobile data.
Dedicated leased lines. For very high-stakes events, such as a major shareholder meeting or a large-scale investor broadcast, a temporary dedicated leased line can be installed at the venue in advance, providing a guaranteed, unshared connection specifically for the broadcast. It's the most reliable option, and the right choice when failure simply isn't an option.
Planning the contingency before you need it. The worst time to solve a connectivity problem is thirty minutes before a live broadcast. The right time is during the planning phase, before the event day. Knowing in advance what the venue can and can't provide, and having an alternative already in place, means a connectivity issue on the day is a managed inconvenience rather than a crisis.
What to Ask Your Venue
Rather than "is your internet okay for live streaming?", the more useful questions are:
- Is there a hardwired ethernet connection available at the point where our technical control will be based, rather than relying on Wi-Fi?
- Is the connection dedicated to our event, or shared with the rest of the building? If shared, what guarantees can you offer on bandwidth during our event?
- What is the guaranteed upload speed, and how is it measured? Can we run line tests on arrival?
- Is there a secondary connection available if the primary fails?
- What has happened in the past when events have tried to stream from your venue?
A venue that can answer these questions confidently is a venue that understands what a broadcast event needs. A venue that can't is one where it's worth bringing your own connectivity solution, regardless of what they've told you over the phone.
The Broader Point
Connectivity is the element of live event production that clients most often assume is sorted and least often verify. It's also the element most likely to cause a visible, immediate problem during a live broadcast.
The good news is that it's entirely manageable with the right approach: assess it early, test it on the day, and have a backup that doesn't depend on the venue. Taking that approach means connectivity becomes one less thing to worry about on the day, rather than something left to chance.
