One of the most frustrating terms in the wireless industry is the term “site-survey”; it means one thing to some and a completely different thing to others. The reality is that having such a mixed consensus on what the term really means is confusing and in a lot of cases causes the wrong expectations and ultimately a poorly designed, poor performing WLAN.

It’s time we try and settle the confusion.

Here’s what a wireless site survey really means and how to ensure you get the most out of your next wireless network design.

To understand what a wireless site survey is it’s important to understand what it’s not. It’s not the design process itself as some claim it to be and it’s not a validation visit after the installation has been completed

A wireless site survey is merely a component of the design process.wireless_network_design_process, wifi service providers, site survey,

So, if we’re going to refer to the entire design process we should do just that and refer to it as wireless network design.

1 – Analyze

This is the first step in any design, defining where your current network is and then making recommendations to support your specific needs and/or requirements. This can involve a multitude of tests such as networks assessments, security assessments, and application performance testing.

2 – Design

Now it comes time to actually meet those requirements defined through the previous analysis and benchmarking.

*Remember: The application (what you’re trying to do) drives the infrastructure (your wireless LAN design). You can learn more from a recent article here.

It’s common at this point to perform a predictive site survey or when possible an on-site wireless site survey. Either one is necessary to determine specific RF characteristics and to establish the exact scope of the environment.

3 – Deploy

This is where your wifi service provider will mount AP’s, configure controllers and physically set-up your network. It’s important to note that before you attach any AP’s to a wired network that you should test for PoE, DHCP, VLAN assignments, Default Gateway and DNS.

4 – Support

Once your new network is in place it’s time to do a validation site survey to test your network and make sure that all of the requirements outlined in the first step have been either met and/or exceeded. This is a critical step to make sure that your new wireless design is correct and functioning at the highest performance levels.

It’s easy to design for coverage but in a mobile “always-on, always-connected” world, capacity and security become the greatest challenges. Simply adding more and more AP’s will not guarantee more capacity; in reality it will only lower throughputs and lower your networks performance.

If we want to talk about site-surveys do just that and be specific: predictive, on-site, validation, active, passive, these are all types of site-surveys. If we want to talk about wireless network design let’s talk about design and not just one piece of it.
