How to optimize wireless bridge after deployment?

[Point – to – (Multi) point Deployment)]

In the real world of networking, a wired network is generally preferable to a wireless connection. However, a wired connection is not always possible, due to a prohibitively high cost of running Ethernet or fiber. In some cases, it may simply not be physically possible to run cabling.

An alternative to a wired link is a wireless bridge, known as a wireless distribution system (WDS). A wireless bridge connects two or more networks together and acts like a “wireless wire” from the perspective of both sides of the link. The bridge itself is transparent to Layer 2/3 traffic transmitted over the link.

This article provides recommendation to EnGenius users/installers on how to ensure a stable and reliable wireless backhaul deployment.

  • Manually initiate channel scan process at any time. This can be done by using Wi-Fi Analyzer, such as MetaGeek inSSIDer, or a spectrum analyzer, such as the MetaGeek WiSpy dBx.

  • EnGenius recommends manually running the channel optimizer again each time additional non root bridges are added (after the aiming process is complete). This allows the bridges to accommodate any RF interference at the new non-root bridge that would prevent optimal performance.

  • Whenever possible, EnGenius recommends using the DFS channels (UNII-2 and UNII-2e shown in yellow below) for a wireless bridge link, as these frequencies are generally less used compared to the UNII-1 and UNII-3 bands (shown in white), which are popular for consumer Wi-Fi.

  • If performance is still poor after channel optimization and power adjustment, this may be due to nearby RF interference or positioning; in first case, check for a different channel. In the second case, try to re-aim the units. If none of these procedures works, a change of location for one or more of the units may be required.
