I have a question what is the best setup for football stadium.
I can mount equipment (433ah) on each (4) lof the lights (reflectors) towers.
What antennas to use? Lower dBi (17 dBi) or more powerfull (21dbi). Those are Sector antenas witch 150 degrees coverage.
I was thinking that the best setup would be 2 21dBi Sector antenas per 433AH AP.
The 4 APs are linked together via Bridged ethernet ports (optical connection with OPT2LAN convertor). With this setup I could serve around 400 clients (8 radios with 50 cients per radio).
How should I setup SSID and Channels? Use the same SSID and same channel. What happens when one radio reaches maximum clients (40-50). Will other automaticly try to connect to other radios?

A higher gain antenna will provide a wider coverage area which is also a source of interference(noise). so your area of coverage will determine your antenna requirement.

I usually used only one SSID to identify a service, I used one SSID for a whole town, Used different channel to avoid interference.Your antenna direction can play a role in determining signal and noise. Client will automatically access strongest channel, he can also change channel manually.
So I would be better of using around 15dBi antennas for a footbal stadium, since the light towers are max 200 meters apart and high above (around 50m).. Lower dBi should pickup less noise and thus provide better stability for multiple clients.
It is intened for reporters for footbal matches and some for general public (visitors of a game, lower bandwitdh).
What happens if the AP is maxxed out (max clients) will the AP stop broadcasting SSID or how will the client know to use another AP with maybe a bit weaker signal?
In general, the lower the dbi, the wider the beam. 21db antennas would be overkill in your application. 120 deg, 12 dbi sectors at each corner would work fine for you. Use WDS or pseudo bridge. Careful you don’t scramble the quarterback’s brains when the line of scrimmage is near mid-field.
In general no, the above general statement is correct, then again, beam width, tilting angle, play a role. or maybe “wider” is interpreted as “distance”.
Agree with 12dB could do the job, your antenna beam width selection is determine by your target area. 90-120 degree could do the job, then again why cover the playing field if you don’t need to.
Not sure this will happen, not sure if the second question is possible, unless done manually by client. I have only max 30 client per AP, more client I distribute using more AP per coverage area. haven’t had any case either.
I did answer that at the top, I used only one SSID for a whole town, you could have different SSID for each corner to differentiate a coverage area, but using the same channel when the coverage overlap is an absolute no.
You really don’t need to hardwire the ethernet feeds to all 4 corners of the stadium. One can be fed and the other 3 in WDS or mesh provided you can take the bandwidth penalty. I do this quite often with Deliberant radios-same channel, unique SSIDs-in a WDS string, but it can be implemented with all MikroTik gear as well.
