Solution Overview
Parks and squares in wireless city projects have the following characteristics:
- These areas are open and spacious.
- Users move frequently.
- Most STAs are mobile phones.
- No high bandwidth is required. Only wireless coverage is required.
- WLAN devices have high protection requirements.
If APs can be installed in central areas, use outdoor APs with omnidirectional antennas. If APs cannot be installed in central areas, use outdoor APs with directional antennas against lamp poles or walls of surrounding buildings.
Table 1 lists AP models used in parks and squares.

Remarks |
|---|---|---|---|
*Drawing |
Confirm information completeness of drawings, including the scale, or google information about coverage areas. |
||
*Coverage area |
Confirm coverage areas, and classify them into common and key coverage areas. |
||
Available channels in local areas |
Confirm available 2.4 GHz and 5 GHz channels in local areas, and avoid using reserved or radar channels. |
||
Effective isotropically radiated power (EIRP) |
Confirm the EIRP values of local 2.4 GHz and 5 GHz channels. |
||
*Required field strength |
For example, not lower than –70 dBm in outdoor areas |
||
*Service usage |
For example, Internet access for passers-by using mobile phones |
||
*Number of users, bandwidth, and concurrency rate |
Confirm the numbers of access users and concurrent users, and per-user bandwidth. |
||
*AP selection |
Confirm whether external or built-in antennas are used, and whether 802.11ac Wave 2 APs are required. |
||
*Obstacles |
Confirm obstacles such as buildings, trees, and greenbelts. |
||
*Interference sources |
Confirm whether signal interference sources exist. |
||
*AP installation positions |
Confirm positions for installing APs. |
||
*Power supply cabling |
Confirm the length of PoE cables. It is recommended that PoE cables be no longer than 80 m. |
