AP location 2. AP quantity 3. Number of users covered by each AP 4. Percentage of concurrent users 5. AP concurrent user- Bandwidth-Distance model Select "Bandwidth-AP concurrent user" model. Calculate the number of APs required. Determine distance between APs: >7.5 m Add new coverage modes and re-calculate the results. N Y AP Capacity Design Example:  Based on customer requirements, calculate the average bandwidth required by each user: 300-500 kbps.  Based on the required bandwidth and terminal frequency distribution (2.4 GHz: 5 GHz = 1:1), select the model "400 kbps —— 50 concurrent users on each AP".  If the total number of users on the first layer of the south stand is 6330 and percentage of concurrent users is 20%, the total number of users that concurrently use Wi-Fi services is 1266 (6330 x 20% = 1266). And a total of 25 APs are required (1266/50 = 25).  As observed from the drawing, the stand is 120 m long.  If all the APs are deployed in side mode (four channels are available), AP distance is 4.8 m (120/25 = 4.8), which is smaller than 7.5 m. Interference may be serious.  Add a new AP deployment mode: overhead. Two rows of APs provide signal coverage at the same layer. AP distance is 9.2 m (120/13 = 9.2 m), which meet capacity requirements of the model "400 kbps-50 concurrent users on each AP".  Results: 1.AP location: above the seats in the last row and on ceiling 2.AP quantity: 26 in total, with13 for each row 3.Number of users covered by each AP: 6330/26 = 243 4.Final capacity model: Number of concurrent users on each AP—— Bandwidth —— Distance = 50 —— 400 kbps —— 9.2 m 5.Percentage of concurrent users: 26 x 50/6330 = 20.54% AP capacity calculation process: Page 23

24. COPYRIGHT ©2006 HUAWEI TECHNOLOGIES CO., LTD. Page 24 AP Capacity Design (''Bandwidth-AP Distance-Number of Concurrent Users on Each AP" Reference Table) Data in the mapping relationship table is being tested. Currently, the following typical data is available. Assume four 2.4 GHz channels are available. AP distance: 7.5 m Number of concurrent users on each AP: 50 (2.4 GHz:5 GHz = 1:1) Average bandwidth per user: 300-500 kbps

25. COPYRIGHT ©2006 HUAWEI TECHNOLOGIES CO., LTD. Channel Design Principles Page 25 1.Determine the available channels at the local site.  Determine available 2.4 GHz channels. In counties that support channels 1-13, use channels 1, 9, 13, and 4 to increase the distance between co-channel APs if many APs need to be deployed.  Available channels vary in different countries and regions. Some countries or regions will reserve some channels. Select channels based on the conditions at the local site.  In some countries or regions, available 5 GHz channels may differ in indoor and outdoor scenarios. Select channels according to local standards. 2.Plan the channels.  AP channels should be properly planned to prevent interference. When planning AP channels, avoid interference from existing signals, which is of great significance to ensure high access quality.  Overall channel planning rules: Co-channel and adjacent-channel APs should be deployed far from each other to increase channel multiplexing efficiency. Additionally, interference between APs on the same layer or different layers should be considered. 3.Example: Second layer stand CH9 CH 36 First layer stand CH1 CH 44 CH13 CH 52 CH5 CH 60 CH9 CH 100 CH1 CH 108 CH13 CH 56 CH5 CH 104 CH9 CH 120 CH1 CH 136 CH13 CH 44 CH5 CH 52 CH13 CH 116 CH5 CH124 CH9 CH 132 CH1 CH 140 CH13 CH 40 CH5 CH 48 CH9 CH 64 CH1 CH 112 CH13 CH 128 CH5 CH 116 CH9 CH 124 CH1 CH 132
