Wifi comes in licensed and unlicensed frequencies, it’s always better to consider which works best for your area. Licensed spectrums are increasingly greater as they bring benefit through better performance and a greater reliability. Unlicensed spectrums are always competing with the other users around. There
is less protection than what you’d receive for a licensed network. Not to mention unlicensed spectrums have limits on their air times, limiting how much you can do.
Wifi is not as simple as we think, not just as simple as coming and plugging in. Not like a single dwelling. Wifi requires design, expert knowledge, and analysis. Substantial design is crucial as is an understanding
on what’s going on in all aspects of it. Anybody can turn on wifi, anyone can use. The more traffic the more congestion, and congestion could
bring bad interference. Wireless has its limits though, and the right network must be installed for a location. If one carrier pays for licensed spectrum, they can only take up space, causing less irregular interference.
Channel interference plays a huge part in the way wifi functions and with it, most signals wouldn’t work. Signal to noise ratio (SNR) is a measure used for this, used to compare levels of signal to the ratio of background noise. How strong is the signal? What obstacles disallow it from working properly? What interferers are present there?
Linkwave Wireless does RF surveys and walk tests in order to better understand environment. To help us design a better network since channels are usually planned around the environment. We utilize tools such as EKAHAU to place the right number of access points in the right location, and iBwave for our in- building solutions.
