What are the Best Practices When Cabling for Wi-Fi?


Who doesn’t love Wi-Fi?  Wherever you are, when you’ve got that little symbol telling you’re online, you’re in business.

Well, in a perfect world.

The frustrating thing about Wi-Fi is that the signal quality isn’t consistent, even within the same building.  It can cut in and out or show access and then refuse to navigate between web pages, or to your web-based inbox.

So, what are the best practices when cabling for Wi-Fi that’s more reliable and consistent?  Let’s explore them, in this post.

Access Points

A wireless access point set up (AP) is how you can get around inconsistent access.  You create a WLAN (wireless local area network) to encompass your entire operation.  Every AP is connected to a hub with an Ethernet cable, serving designated areas with consistent, readily accessible Wi-Fi.

Wherever in your building you require access, an AP can be established.  You’re then connected directly to the server room, with the Ethernet cable used as your conduit.  Dedicate one specifically to your meeting room for uninterrupted access that doesn’t compete with operations outside it’s door.

Keep in mind that an AP can manage over 60 connections at once.  That gives you incredible coverage anywhere in the building.  As employees move through the building, they’re supported by an AP which maintains their connection seamlessly.

Making AP Work

You may have guessed by reading above that an AP is only as good as the cabling that supports it.  Let’s look at what it takes to support AP for Wi-Fi coverage.

Determining the area to be served is key to setting up an effective AP system.  This will tell you the most advantageous position for each AP and service outlet.  Annex A.3 of the ISO/IEC 11801-6 sets out the average indoor range to be covered by an individual AP.

Bandwidth is another key consideration.  Your cabling should be future-proof (with 5G on the immediate event horizon).  So, each service outlet should be served by 2 6A cables to support the accompanying AP.  Each cable will support 10 Gbps of bandwidth up to a distance of a little more than 328 feet. That provides a healthy 20 Gbps for every AP installed.

Cabling experts will take into account factors in the individual building which may interfere with access then determine what’s required to mitigate that interference.  Factors like thick walls and high ceilings are challenges, but best practices when cabling for Wi-Fi can get around them.

We’re glad you read this post, so we can let you know that cabling is the foundation of a genuinely accessible AP-supported Wi-Fi WLAN.  Designing it well is the gift that keeps on giving, in terms of ease of access and employee productivity.
