Wi-Fi doesn’t have to be mediocre

There is of course truth in a wired network being more reliable than a Wi-FI network.  Radio is undoubtedly harder to control than sending signal along a cable.  However, done well, there is no reason why Wi-FI shouldn’t have the same availability, up time, coverage and speed as a network cable.  It’s time to say goodbye to the myth that Wi-Fi has to be mediocre. 

By carefully designing and planning Wi-Fi, we can create networks with great speeds, coverage and reliability.  Poor Wi-Fi is often the result of interference.  Astonishingly, in the business and hospitality environment, this interference is more often than not caused by Wireless access points from the same network.  Increasing the number of access points without design consideration doesn’t solve any issues, it creates them.   The key to a successful Wi-Fi network is design of the right number of access points with power and channel planning to ensure that interference from neighbouring access points doesn’t occur.

Having too many access points can cause interference as, if they are on the same bandwidth as a neighbouring access point, they will cause radio interference to one another.  The same is true if they aren’t set to differing channels or their power isn’t adjusted to be optimal for the area of coverage.  Other common mistakes include bad or incorrect mounting of Wireless access points.  Generally Wi-FI access points should be ceiling mounted and not behind any obstructions, in particular metal. 

It’s true that Wi-Fi isn’t as forgiving as a wired network, but if it is carefully planned and implemented with design, survey and best practice knowledge, it can be just as reliable, fast and secure.
