In large commercial buildings I typically see several ceiling mounted Wireless Access Points. When moving throughout the building, I do not have to continually reconnect to different networks (or SSIDs).

I assumed this is what WAPs do: You plug them into your Router or Switch and they create a wireless network. You would then give the same SSID from your existing wireless network and you would have a larger, better network.

However, posts such as this make it seem like each WAP may need to have its own SSID.

If this is the case - how do large commercial businesses create large, non-mesh wifi networks?

  • Unfortunately, product or resource recommendations are explicitly off-topic, except on Software Recommendations and Hardware Recommendations. As far a business go, there are a few ways to do this, and you would need to ask the specific business. Questions about networks not under your direct control are off-topic here. – Ron Maupin Oct 5 '20 at 20:01
  • @RonMaupin I deleted the product request - but this question is very similar to the linked-to (non-closed topic :) – Startec Oct 5 '20 at 20:03
  • Your assumption is correct. In non-mesh wireless networks, you can still configure all of the APs to broadcast the same SSIDs so you can move between them nearly seamlessly. The difference between mesh and non-mesh is essentially just how the connections get back to the main gateway/router. Non-mesh has to have a direct path to the main gateway; mesh can do that or talk to each other to get a path back. – Jesse P. Oct 7 '20 at 12:34
  • Most large non-mesh networks are still controlled through wireless controllers which also allow for things such as fast (or rapid) transitioning, so clients can move between APs without having a drop, by the client establishing a connection to the second (stronger) AP before terminating the connection to the first (weaker) AP. – Jesse P.

  • @JesseP but the "wire controller" part is optional essentially? – Startec Oct 7 '20 at 22:11
