Here is a response we got from a successful deployment in  the Peking University of Beijing.

Their objective was to turn their University's open grounds into a big hotspot using 2 base stations.

Here is their response to our query:

After testing for awhile your product

we found the following

1. We can cover out door environment effectively with one A8 base station covering ˝ sq km area in average.  So for a radius of 2km which equals to 12 sq km area,  we need about 24 x A8 base station.   It could be less or could be more depends on the actual environment, but it is a good way to do your budgeting.
2. If you start our A8 from scratch, then first the outdoor environment will be covered by the 24 systems, for the indoor cover, it will mostly cover through first or second glass/wall inside the building.   However, we recommend to use a “low cost CPE” to “Bridge” the outdoor signal to indoor which the environment is not controlled by us.
3. Our outdoor A8 base station will work very well with the existing indoor AP because we have smart antenna to maximize the RF channel utilization.   
4. Each A8 base station is designed to have 256 simultaneous associated users to share total 54 Mb bandwidth.   We have tested with 63 active users with good data performance.   For 8,000 students, I assume 20% of people will be outdoor at the same time, and 20% of them will access internet outdoor, then we have 320 outdoor users (8,000 x 0.2 x 0.2),  so we have about 13 users per base station (320/24) which is well below our design limit.
5. For application, we can use all standard WiFi terminals which means Notebook PC, PDA, IP/WiFi phones.  However, depends on the terminal transmit power, the distance will be varied.  For example if the Note Book PC with 50 mw transmit power we can for long distance of transmission (500m), for others like low power PDA/WiFi Phone with 20 mw transmit power, then the distance will be reduced to 350m-500m.

In summary, to turn a university to a Big Hot Spot is very easy with our WiFi Cellular Base Station.  Just plug in the RJ45, and put the Base Station on the roof top, then the 500m radius area will be very well covered.  As simple as install your home AP!
