Will MikroTik RB2011UAS cope with the role of a router in a restaurant?

Question

WiFi

Good afternoon community.
MikroTik RB2011UAS-2HnD-IN - will this router cope in a restaurant, provided:
Two isolated wi-fi networks:
1. There will be 4 employees + a printer in one network.
2. In another network, guests, a maximum of 40 people (extremely rare, but it happens on holidays), and usually an average of 10-20.
The area of ​​the restaurant is about 80 square meters, there are no partitions, an open area, a basement.
Nothing is connected via LAN, everything is only over the air
Employees have win-laptops (HP)
Guests mostly use smartphones/iPads.
Can I safely take it or is it better to look at something stronger?
Thank you!

Answer 1

You can't deceive physics - it will work badly. Even expensive ciscos for 25+ people on the air are starting to blunt worse than EDGE.
Another question is, if you don’t have anything else on the air at all, then 20-30 people will be fine. 40 is unlikely.
In addition, do not forget that the network will operate at the speed of the slowest client (someone will pick up at a speed of 1 mbps - everyone will have this).

Answer 2

Channel 20Mb.
There were no plans to cut speed, but if you can set a specific SSID, then it would be good (so that the employees have the Internet as a priority, and the guests have a residual principle).
Employees need the Internet only for mail, otherwise normal surfing, without movies and other things.
Both networks are password-protected, the working SSID is hidden.
The password for guests is public, i.e. only protection from the "fool".
Thank you!

Answer 3

Those. everything rests on the width of the channel? The router itself will pull 20-40 Wi-Fi clients easily?

Answer 4

The basement is deaf, there are no other networks.
Prior to this, a year and a half, guests used a network of iota + TL-MR3020.
And now the guests began to complain about the speed, the management decided to upgrade the guest wifi.
If this Mikrotik fails, can you recommend any specific model that can easily withstand 40 people and be able to create two isolated wifi networks?
About 1mbps - can you explain "on your fingers"? Didn't know about it :(
And this applies to all routers?
Thank you for your participation.

Answer 5

Thank you very much to everyone for their participation, and for the educational program too :)
I'm a little surprised that an area of ​​80 square meters is so difficult to cover with a network.
A friend has a cottage of 500 square meters and there is an ASUS-RT66U router on the second floor, on any of the 3 floors the network catches, except for the basement.
Or is it not the area, but the number of customers?
We will think more.
Thanks again to all who responded.
