Solution Overview
From the perspective of network planning, venues in wireless city projects are divided into common venues and high-density venues.
- Common venues (such as libraries and cultural venues): Generally, such venues have low user density, with a height to ceiling of less than 5 m. In these scenarios, indoor APs with built-in omnidirectional antennas are mounted on ceilings or walls, and are spaced as required.
- High-density venues (such as stadiums and theaters): Such venues have tiers of stands and high ceilings, with high user densities and high demands for Internet access. In these scenarios, small-angle directional antennas are used to control the coverage of a single AP. This increases the number of APs to allow for more access and concurrent users.
Table 1 lists AP models used in common and high-density venues.

Remarks |
|---|---|---|---|
*Drawing |
Confirm information completeness of drawings including the scale. |
||
*Coverage area |
Confirm coverage areas, and classify them into common and key coverage areas. |
||
*Required field strength |
For example, not lower than –65 dBm in indoor areas |
||
*Service usage |
For example, Internet access by mobile phones |
||
*Number of users, bandwidth, and concurrency rate |
Requirements in the stand area and other common indoor areas |
||
*Available channels in local areas and EIRP |
Confirm available 2.4 GHz and 5 GHz channels in local areas, and avoid using reserved or radar channels. Confirm the EIRP values of local 2.4 GHz and 5 GHz channels. |
||
*AP selection |
For example, APs with external or built-in antennas |
||
*Floor height |
Confirm the floor height to determine the positions for installing APs. |

*Obstacles |
Confirm onsite obstacles such as walls (wall materials and thickness). |
||
*Interference sources |
Confirm whether signal interference sources exist. |
||
*AP installation positions |
Confirm positions for installing APs (ceiling/wall). |
