Hi,
Usually, when we plan the WLAN implementation, we should calculate the bandwidth needed firstly, so that we could make the right decision of AP quantity.
Total bandwidth requirement = total number of users * concurrency rate * per user bandwidth requirement
AP Quantity = Total Bandwidth Requirement / Bandwidth per AP
Example:
The capacity of WLAN network is reflected in bandwidth. Take 11g as an example, the air rate of each AP is 54 Mbps, and the throughput of each AP is about 20 Mbps.
For a first-floor dormitory building, there are 20 dormitories, each with 5 people having Internet access demand and 2 Mbps of Internet bandwidth per user. The concurrency rate of users accessing the Internet at the same time is calculated at 30%, and three AP should be placed on the floor.
AP Quantity = 20*5*2*30%/20M = 3
The actual number of users in an AP should not exceed 30; if there are too many users in the coverage area, the share of the number of AP should be increased.
Hope this could help you a lot.
Thanks!
