For a live stream the number that matters is upload speed, not download, and you should measure it at the venue rather than trust the brochure.

Measure several times, ideally at the same hour as your event, because a network that is fast in an empty hall can slow down once the audience arrives.

A wired connection from the venue is almost always the most stable option, so ask for a dedicated cable to your position as early as possible.

Ask the venue technicians whether outgoing traffic is filtered, because some networks block the ports that streaming protocols use.

Hotel and conference Wi-Fi often requires a login page in a browser, which a hardware encoder cannot complete, so request an exception or a separate line.

Never share your streaming connection with the guest Wi-Fi, since hundreds of phones will compete with your encoder for the same upload.

Cellular routers with external antennas are a solid backup and sometimes the main line, but a full stadium can congest every nearby cell.

Bonding combines several connections, usually SIM cards from different carriers, into one stream, so the loss of one network does not end your broadcast.

A bonded system needs a receiving server that puts the pieces back together, which is why bonding is sold as a device plus a service.

Simple failover is different: it switches to a second connection only after the first one fails, which can cause a short interruption.

Satellite internet works where there is no other option, but it needs a clear view of the sky and its upload is modest.

Set your encoder bitrate well below the upload you measured, because a connection that tests fast can still dip during the show.

Protocols designed for unstable links, such as SRT, recover lost packets and cope with jitter far better than plain RTMP.

Send a second feed from a separate connection when the event matters, so the platform can switch to it if your main line stops.

Record locally at full quality as a safety copy, which lets you publish a clean version even if the live stream stuttered.

Do a full rehearsal on the actual connection, with the encoder running for at least an hour, because short tests hide slowdowns.

Ask the venue for a contact on its network team and their mobile number, because the person who can fix a blocked port is rarely the one who opened the door.

Label your own network cable at both ends, so nobody unplugs it to charge a laptop during the event.

A small uninterruptible power supply for the router and encoder keeps you online when someone trips a breaker backstage.
