What are the best practices when cabling for Wi-Fi?

An infrastructure design consideration that arguably frustrates users, and creates a never-ending headache for network administrators, is the quality of Wi-Fi service in a building. Typically, a poor user experience is one where users have either no signal on their wireless device or see “full bars” but cannot connect to the network.

In an office environment poor Wi-Fi performance is undoubtedly an annoyance, but in a hospital, it could prevent medical staff from delivering care in a timely manner. Waiting for a mobile terminal to retrieve the medical history of a seriously ill patient can literally be a matter of life and death.

Proper cabling is the foundation of Wi-Fi performance

Configuring a wireless access point system (AP) is a complex project and is not the subject of this post, although Aps or AP systems of course plays an important role in Wi-Fi network best practice. To provide network integrators with the best chances of success, the cabling infrastructure must be available to support optimal installation and placement of AP.

Annex A.3 of the ISO/IEC 11801-6 standard provides guidelines to network cabling designers that should be considered when placing cabling to support Wi-Fi and other wireless applications. Primarily based on the frequency band of and data rate of Wi-Fi services, the standard lists typical indoor ranges (radius of an AP) that should be used to determine the coverage of an average grid. The grid is then used to determine the placement of service outlets (SO).
