Problems in your wireless network?
We love to put our teeth into the toughest WiFi-problems!
Troubleshooting or a second opinion?
We measure and analyse your network with state of the art toolsets. In an extensive report you receive all possible options you have to improve your networks performance. Whether you want to implement these changes with the help of your own IT staff or with our help, the choice is yours. We would love to take your IT staff on a learning curve during the project.
We use state of the art equipment
We create an extensive, comprehensible report
We invite your IT staff to the project
Wireless site survey
By performing a wireless site survey we visualise the state of a complete wireless network. We pay attention to signal strength, channel usage, channel width and the maximum attainable theoretical speed. A performance test to see if the wireless network (still) meets the requirements is certainly part of this exercise.
By performing a spectrum analysis, we examine the electromagnetic spectrum and then solve the problems. WiFi exists on the first two layers of the OSI model. Wi-Fi is very ‘polite’: does it hear another WiFi transmission on the same channel or is there other electromagnetic energy present at a strength of -85dBm or stronger? The other WiFi-devices remain silent.
Sometimes there are problems in a network that are located in the higher OSI layers. By means of packet capture we see all data streams from and to devices on a specific channel. For example, we can discover whether the driver of a WiFi adapter can be the problem or why the 4-way hand-shake is not going well and logging in to the network is not successful.
A WiFi signal is divided into three: ‘want’, ‘do not want’ and ‘do not care’. We want a signal of -67dBm (want), but we do not want an overlap of the same channel with a signal of -85dBm or better (do not want). A signal of less than -85dBm does not bother us (do not care). This is the basis of a good channel distribution.
