In order to get maximum performance out of your wireless network there are a number of specific and important components to take into account. By performing a wireless site survey, we will be able to tell if these important requirements have been met for your network, and more importantly we are able to make recommendations on the changes required for maximum throughput.
Before we perform the survey, we require a floor plan of the building. The more to scale the plan is the more accurate our data collection will be. We insert the floor plan into our powerful site survey software and set a scale for the plan. Now with 4 antennas inserted to the survey device we walk the whole site, through every room, corridor and even outside, plotting on the plan every path we make.
Once the wireless survey is complete, we will analyse the data collected. This is the important part of the survey, by looking at the data we can identify any areas of concern in the network and start to put together a plan to remedy the problems. We will look at Vendor Type, AP model, AP locations, signal strength of Each AP and finally full site wireless interference. We will explain each component in more detail below:
Vendor Type – It is important to ensure the whole wireless solution has only one vendor of wireless AP. This is because all enterprise grade solutions have powerful technology designed to hand over the users from AP to AP as they move around the campus. As well as being able to hand off users in high use areas to Aps that are perhaps not under such heavy loads.
AP Model – You need to choose a model of AP that is fit for purpose. If you have a small number of clients that only do emailing then there is no need for the most powerful wireless device. But if you have a classroom with 30 students each having 2-3 devices each then you are going to need a device that can deliver fast data rates to each device.
AP locations – Perhaps one of the most overlooked parts about network installation. Moving a wireless AP, a metre each way can drastically modify the whole wireless environment. If you are having signal strength issues, then this could be a simple yet effective solution ad we can easily identify this on the survey.
Signal Strength – Signal strength is important for dense environments where there is a large number of users and APs. You do not want your wireless network to be broadcasting over the range to which it is designed to cover. If it does this could have serious negative impacts on the overall user experience.
Wireless Interference – We want to avoid as much interference as possible. When there is interference the end user will notice the impact on the network. There are many types of interference such as other clients on the network, other APs in the environment, wireless CCTV and even microwaves. We are able to look at the interference and make channel and power changes to reduce as much of it as possible for a seamless connection for the end user.
When we perform our wireless site surveys, we ensure all of these components above are looked into and then if we find issues with any of them we will document the changes required and pass on to the customer in a detailed report.
