Solution Overview

Solution Overview

Transportation hubs in wireless city projects include train stations, coach stations, bus stations, and airports.

  • In indoor areas such as waiting halls of train stations, coach stations, and airports, most STAs are mobile phones. In such scenarios, users move frequently, and high network capacity is required. Depending on different building roof heights and user densities in these scenarios, outdoor AP8150DNs with external small-angle antennas or indoor APs are recommended to provide wireless coverage.
  • In outdoor areas such as bus stations, most STAs are mobile phones. In such scenarios, no high bandwidth or network capacity is required, and users move frequently, so only signal coverage needs to be considered. Outdoor AP8050DNs or AP8150DNs with external omnidirectional antennas are recommended.

Table 1 lists AP models used in different scenarios of transportation hubs.

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.

*Required field strength

     

For example, not less than –65 dBm in indoor areas and not less 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.

*EIRP and available channels

     

Confirm available 2.4 GHz and 5 GHz channels in local areas, and avoid using reserved or radar channels.

*AP selection

     

Confirm whether external or built-in antennas are used, and whether 802.11ac Wave 2 APs are required.

*External antenna

     

For example, directional antennas are used to provide coverage for roads, and omnidirectional antennas to provide coverage for open areas

*Obstacles

     

Obstacles on sites, including bearing columns, closets, and partitions in indoor scenarios, and buildings, trees, and greenbelts in outdoor scenarios

*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
