Wi-Fi network deployment is not a trivial task and should not be performed without thorough analysis and planning. Here are some tips:
The location should be surveyed to find out the area and number of floors to be covered. Bear in mind that ceiling, wall, and flooring thickness and materials could affect the propagation of Wi-Fi signals.
Use AP Discovery (Wireless LAN >> AP Discovery) and Interference Monitor (Diagnostics >> Interference Monitor) on the access point or router to identify the channel with the strongest signal and the least amount of congestion. Also, there are mobile apps available from iTunes and Google Play stores that can assist in the analysis of the Wi-Fi spectrum, such as Wi-Fi Analyzer and InSSIDer.
You can use the AP Map feature (Central Management >> AP >> AP Map) to determine the optimal locations to install access points on your premises. For more information on AP Map, please refer to the article Plan Wireless Coverage with Central AP Managemen. It is recommended that access points have 15 to 20% overlapping coverage to ensure adequate overall coverage.
The ability of wireless networking devices to penetrate the obstacles depends on several factors:
|Wood panels||Low||Inside walls|
|Fabric||Low||Furniture, cubicle partitions, curtains|
|Tinted glass||Medium||Exterior windows|
|Concrete||Medium to High||Walls|
|Metals||High||Metal furniture, metal doors|
Consider enabling Wi-Fi roaming to provide users with a better online experience. Wi-Fi roaming lets wireless clients roam between different access points within a network with minimal service disruption to provide seamless connectivity. Visit Wi-Fi Roaming with VigorAP for more information.
Each frequency band on a Vigor AP can support a maximum of 64 MAC addresses at any given time. (AP920R could afford up to 128 MAC address per band). Additional access points might be required depending on the number of wireless clients that will be online simultaneously. Enable AP Load Balance to distribute network load across multiple APs evenly. See article Client Load Balancing by Central AP Management for more information.
For the dual-band wireless model, we could also enable the band steering for 2.4GHz with the less congested. At the same time, the dual-band client will be encouraged to connect to 5GHz wireless, which is faster. See What is Band Steering for more info.
Consider segregating APs by usage to maintain security and performance. For example, visitors and employees can be placed on separate APs. See article Add a Separate Wireless Network for Guest for more information about client isolation by SSID and VLAN.
For efficient and effective management of multiple access points, use DrayTek’s Central AP Management. See article Start using Central AP Management for more details.
Vigor routers provide a feature called Hotspot Web Portal that can be used to authenticate wireless users or get them to agree to terms of service that are shown on a landing page.
