• each AP can manage 50 client minimum and can deliver 3Mbps for each client and with good latency.

50 clients is more like maximum due to air time availability. If all the clients are very close you can squeeze in a lot of clients because they all will have fast connections. If you have clients further away connected at 1 to 6 Mbps they will eat all the air time. Your 3Mbps requirement is modest, though. It all depends on the client connection speeds and requirements. If you want to analyze it use the Revolution Wi-Fi Capacity planner at http://www.revolutionwifi.net/capacity-planner/

I have written an article How many users can one Wi-Fi access point support? available at https://metis.fi/en/2018/02/how-many-users/

As for the MikroTik devices I have found hAP AC to be quite capable. It has good radios and routing performance. You hint at sector APs so are you deploying this outdoors? It really would help to know more about the intended use.

You are not helping much. I already guessed it was outdoors.
What kind of deployment? It is a totally different matter to serve 300 people scattered around a park than 300 people packed in front of a concert stage. How much freedom do you have in AP placement? How are going to supply power? What kind of network do you have? How are you going to distribute network to the APs?
You wrote about sector APs in a tower. With 60° sector antennas you could place six APs in the same tower, which could serve the 300 clients from a single point - if the clients are distributed evenly around the tower and reasonably close. How about two or three towers with three 120° sectors each? How about sector antennas around the perimeter aimed in towards the users?

Are we talking about a WISP setup here? (Again it is me guessing..)

I have no experience with running a WISP, so I'll step aside then. My advice concerned providing Wi-Fi service to client devices directly.

It would have saved my time and you would get better responses if you'd given some background information. If it is secret then you need to hire a consultant under an NDA.

Guessing you're going to use 3 120 degree sectors to cover a full 360 degree around the site?

The RB800 should be fine for that (although never even seen it) but get some decent sectors antennas with noise isolation/shielding.

For clients I'd either use SXT (closer), Disc (medium) or LHG (far). All of them should be OK.

If you're running Mikrotik only, I'd suggest using NV2 protocol and using the latest 6.42+ software for the increased throughput fix.

Personally I'd use the following
Site core: https://mikrotik.com/product/RB750Gr3
Sector radio: https://mikrotik.com/product/RB911G-5HPacD-NB or https://mikrotik.com/product/RB912UAG-5HPnD-OUT
Sector antenna: https://dl.ubnt.com/guides/tisector/air ... Ti_QSG.pdf

Modular approach, so things can be swapped as needed or if something breaks.

we are talking about wisp therefore my suggestion using RB800 because we are handling minimum per AP 50client.
how many basebox can handle client..?

i dont have experience with basebox need advice for best AP especially mikrotik.

Thanks

rb800 is an old way to do things

i refer to the model of one CPU with many radios, that was valid an very popular decades ago but not today

nowadays designs have migrated for single Radio per equipment to improve performance and isolate radios between them, preventing self interference

finally rb800 gets you an expensive less performance solution than separated equipment:

for example you get a rb800 and every thing you need to get 4 radios operative with 19dbi 120° antennas you spend close to 1.200 US

instead of that you get 4 mantbox with the same antenna plus a powerbox pro to power it in group you spend only 900 bucks and get best performing solution without the hassle of managing pigtails from radios to antennas

The Mantbox 19s is a cheap and good performing solution, but it is not a good solution overall. As a wireless engineer you should cherish and preserve spectrum by using best possible basestations. Cheap antennas will pollute big chunks of spectrum for miles so it's akin to shooting oneself in the foot!

Thanks to @mbfound @chechito @networkfudge for your reply and time.
and thanks for all advice given to me.

i think i will use netmetal as AP and ya i will manage per sector at least minimum 30 client each sector.
and for client i will use SXT client, and use NV2 protocol for this setup.

@mbfound how many client you can handle each sector..?

Thanks a lot guys.

Hi,

No experience with triple chain sectors - I've never seen them for sale anywhere. Have only used https://mikrotik.com/product/RB921UAGS-5SHPacD-NM so far.

Wireless N should be ample for 3Mbps clients.
