NBA Arena Technology: The Invisible Team Behind the Game

BASKETBALL · ARENA TECHNOLOGY · VIGO

Imagine the final seconds of a close basketball game in Vigo. A player scores, the crowd jumps up and you reach for your phone to watch the replay. Instead, a loading symbol appears. The person next to you has already described the basket twice and identified three fouls the referee missed.

A reliable connection matters at exactly that moment. Video has to reach production teams, arena screens and people watching elsewhere. Spectators may also want to share their own clips. A recent announcement from the NBA and WNBA gives us a reason to look at the connections a future arena in Vigo would need.

What the NBA and WNBA announced

On 19 October 2026, the NBA, WNBA and AT&T announced a new generation of their High-Speed Arena Network, known as HSAN. This network carries game content, replays, highlights and statistics.

The announced target for the 2027–28 NBA season is to carry more than 118 simultaneous streams per game with little delay. Put simply, the system is being designed to move many separate feeds of game content at once. Broadcast connections and spectators' phone services have different jobs, so they need to be planned accordingly.

A busy connection and a broken connection

First, two useful words. Capacity is how much data a connection can carry. Latency is the time data takes to arrive. A connection can have plenty of capacity and still suffer delays. Cloudflare explains the difference in more detail.

In the example below, video and fans' uploads share a limited amount of capacity. When everyone starts uploading, the video can be delayed. One improvement is to reserve enough capacity for video, keeping that allocation available even when the crowd gets busy.

But reserving capacity does not repair a broken cable. For that, the video needs another way through the network: a backup route. The backup must be able to carry the traffic and avoid the same fault that disabled the main route.

Try the two designs

Choose One shared route, then try Everyone shares. Next, select Primary route fails. The purple dots show phones trying to upload, but the data stops at the red cross.

Now choose Capacity reserved for video + backup and repeat the experiment. The design keeps capacity available for video and provides another route when the main one fails. The monitor represents a video destination; people could also watch that video on a phone or television.

Can you keep the replay moving?

Choose a design, then give the arena a difficult moment.

Video has reserved capacity. Fan uploads use their own allocation, and a backup route is available.

The second design assumes reserved video capacity and an available, independent backup. Real systems also need capacity planning, power, configuration and testing.

What I would ask about a future arena in Vigo

If I were reviewing plans for an arena, I would want a few practical questions answered before the walls were closed up:

• Can technicians reach the cables to repair them or add new connections?
• Do the equipment rooms have reliable power and enough cooling?
• Has someone tested a busy evening and a failed connection?

Shouting “Defence!” at an overheating server is unlikely to help. These things need planning while changes are still easy to make.

The ambition to bring major basketball to Vigo also runs through Pincho's illustrated vision of basketball in the city. An arena built for that ambition would need reliable connections as well as a court.

Would it actually help?

I took a similar approach in the article about a robot that would collect my missed shots. I imagined a small assistant doing a useful job: returning the ball so I could keep practising. That gives us something concrete to discuss and test.

I would judge an arena network in the same practical way. Can people watch the replay? Can the production team keep working during a fault? Can technicians repair and upgrade the system without opening finished walls?

Before opening night, I would rather disconnect a cable during a planned test than discover the weak point in the last two seconds of a final.
