hi guys,
i have to submit a proposal for making a 5000 sqft floor wifi. around 300 all users will be using wifi simultaneously.
i am promoting Mikrotik SXT 2G. please help me with inputs. how many will i need and how can i make all users comfortable based on the signal strength they receive from the AP.
awaiting replies.
thanks.
I nto understand imperial units, but for 300 users, working on compatibility mode
(because I do not think all 300 users have 802.11ac or 802.11n with more than one stream…)
If you start with 54Mbit/s radio only, using only repeater, you can give to all user max 78,3Kbit/s eachone (ignoring WDS etc. etc. etc.)
If you give for each user 512kbit/s you need (512 * 300) / 23,5 = “35” single not repeated AP, assuming all the user are uniformly distribiuted between APs…
(23,5 = Ideal bi-directional speed if the AP link @ 54Mbps)
SXT2G are way to powerful to cover such a small area with so many users. If you want to use 2,4Ghz with single (or even duo) spatial stream g/n antennas your cells need to be as small as possible to avoid interferences. And than it will still be a heck of a job to get it all working…
I think you really should start thinking toward solutions offered by Ruckus (www.ruckus.com) to get such job done. They have frequency band pushing systems that can ‘push’ a a/b/g/n radio to use ‘a’ to clear more of the 2,4G spectrum from units that can work on 5Ghz. (It happens automatically) and by their beam forming technology and centralized controller solution they can probably help you with only 3 or 4 AP’s.
Their AP’s have multiple (up to 26! I believe, have to check on my documentations) antennas in each AP and with their advanced technologies can handle much more units simultaneously than any other single, duo or triple chain technology can handle.
So find a Ruckus reseller near you and all though you might end up with a bigger budget spending they are probably the only ones that can save you from a complete failure…
(I followed the WISE course of Ruckus. So far seen they have the most advanced technology imaginable and available. They outperform top branches like Aruba, Motorola or Cisco in many fields. And they are cheaper than these high end brands. Its just a pity their technology doesn’t bear so much advantage in the open field for normal WISP deployments. With simple duo chain technology of MT we can do the things we need at much better prices. But for stadiums, congress halls, festival they are definitely recommended!
I have implemented net with 7 x Ruckus AP + 1 x Manager device and we have two buildings with 5 floors build with concrete and many glass walls covered. 80 users and many mobile devices are roaming dynamically beetwen these access points with no disconections. Yes, it works.
Sorry for not recommending other manufacturer’s hardware in my post 
Well, 5000sqft (roughly 465sqm) isn’t a big deal in terms of area.
Considering the expected amount of clients I’d suggest to deploy multiple APs on multiple channels (2.4 AND 5GHz).
For indoor usage I’d recommend BaseBox 2 with an extra 5GHz radio card - or BaseBox5 with an extra 2.4GHz card 
I’d say three of these should be able to handle this quite easily.
Go for omnidirectional antennas (there are really nice ceiling-mount 2x2MIMO antennas in the market) and lower TX power to approximatively match your cell sizes.
You might probably like to have a look at my first post in this thread.
Cheers
