Wireless Access

 

Good day , I hope you are well

 

Would you give me you advise regarding the below design

 

Customer have university campus

Class room capacity is 150 user

Class room area 10 m x 8

Application running is interactive learning

There will be live lectures at university at Canada will be viewed here at Egypt classroom

The student will access wireless from their own devices to see the stream

They can ask questions and show presentation also

 

I think that each user will require from 2 – 4 Mbps data rate to have good connection

 

I used 3 x AP-205 for each class

 

Each AP should be loaded with 50 users

Each radio expected to have 25 user

 

By aruba test-bench analysis ,each user will have from 2 – 4 Mbps

 

Is that good or we can increase no of AP at each class room to 4

 

The bad point if larger no of users are 2.4 only as ex

120 user 2.4 & 30 users 5 Ghz

 

Each AP will have 40 users on 2.4 Radio and 10 users on 5 Ghz Radio

Then users on 2.4 will get lower data rate than users on 5 Ghz

   

It is best that you contact a local engineer to look at this.  It is difficult to run an applicationon 2.4ghz that is bandwidth or delay sensitive due to interference and contention.  Whether or not the application is unicast or multicast and can be prioritized would decide what strategy you use.  It might be too much to expect 40 users to run it simultaneously.  If it is video, why not just put it on a projector in front of the classrom, if they are in the same room?

Dear

Customer need to establish interactive learning so we need that the instructor share presentations , videos through wireless and student ask and answer him and view what he display

my plan is to allocate AP to each 40 users then i suppose half of them be on 2.4 and another half on 5 Ghz i ask about if 20 users see the same stream with multicast traffic the stream requires 2Mbps bandwidth so all the users will require 2 M then total of 40 Mbps or they will all see the stream at same time as multicast so the stream is sent with user lowest data rate from of the 20 users and then all of them will need only 2 M as they act as one user and receive the stream at the same time

That might be possible, but it depends on the application delivery and how the clients request the data.  If the application is truly multicast, multiple users can subscribe to a single stream and receive the application.  If it is really unicast, there will be a problem delivering it to 40 users at a time.
