Sophos can help customers to do a site survey, please contact your Account Manager to do so.
A site survey is a set of procedures that allows the surveyor to understand the physical environment from a Radio Frequency (RF) perspective and the business requirements of the WLAN set forth by the WLAN owner. These procedures allow the surveyor to design a WLAN that will have the coverage and capacity to allow applications to perform properly over the wireless network.
A site survey is often the most important piece of WLAN design for many reasons, including allowing the surveyor to estimate how much equipment will be needed for the WLAN to operate as required by the owner.
When implementing a new WLAN, the site survey is one of the most important tasks. Interestingly, some have suggested that site surveys are no longer needed with the use of modern WLAN equipment that is self-configuring and auto-negotiating. However, you must perform a site survey to determine that these automatic systems work effectively or you must at least perform post-implementation validation to ensure that the recommendations of these automatic systems have been effective.
Even if you are implementing a small WLAN with one AP, you still perform a site survey. In these scenarios the survey is less complex and less detailed, but it is still required. Such as survey may be based more on experience than metrics, but it is still a qualified engineer determining where best to place the AP and how to configure it.
Some of the characteristics of an indoor RF site survey are:
