Solution Overview

Solution Overview

Main roads and pedestrian streets in wireless city projects have the following characteristics:

  • The coverage areas are narrow and long.
  • Users move frequently.
  • Most STAs are mobile phones.
  • No high bandwidth is required. The number of users, bandwidth, and concurrency rate are not considered. Only wireless coverage is required.
  • WLAN devices have high protection requirements.

Generally, outdoor AP8050DNs with built-in directional antennas or AP8150DNs with external small-angle antennas are installed against lamp poles or building walls on two sides of main roads and pedestrian streets to provide wireless coverage.

Input Information for WLAN Planning

Information Record

Confirmed (Yes or No)

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.

Special requirements

     

For example, roaming, delay, and packet loss ratio requirements
