• What Is A Wireless Site Survey?

  A proper radio frequency (RF) site survey is the first step in the deployment of a wireless network and the most important step to ensure desired operation.

  A site survey is a task-by-task process by which the surveyor studies the facility to understand the RF behavior, discovers RF coverage areas, checks for RF interference and determines the appropriate placement of Wireless devices.

• Why Do I Need A Wireless Site Survey?

  In a wireless network, many issues can arise which can prevent the radio frequency (RF) signal from reaching all parts of the facility. Examples of RF issues include multitpath distortion, hidden node problems, and near/far issues. In order to address these, you need to find the regions where these issues occur.

  A site survey helps define the contours of RF coverage in a particular facility. It helps us to discover regions where multitpath distortion can occur, areas where RF interference is high and find solutions to eliminate such issues. A site survey that determines the RF coverage area in a facility also helps in determining the number of wireless devices that are needed.

  The site survey documentation serves as a guide for network design and for the installation and verification of the wireless communication infrastructure.

• Can't I Just Do This Myself?

  Be careful not to underestimate the resources and effort required to properly survey, design and deploy a wireless network. Even experienced IT professionals think "you just throw a few access points where needed" or "the WLAN controller will take care of everything". Not true, especially with 802.11, because WLANs operate using unlicensed frequencies and are impacted by neighboring wireless networks, cordless phones, Bluetooth devices and even microwaves!

  Another misconception is that using "predictive RF modeling" software is all that is needed. While a pure predictive design can provide valuable information about wireless coverage and capacity it will not help in understanding what other 802.11 and non 802.11 interfering sources may exist. Combining a manual wireless site survey with predictive RF modeling provides the best approach and a good foundation for future expansion and design tweaking scenarios.

  Also, don't rely solely on wireless equipment vendors to help you design your network. Get independent and unbiased information based on real world experience and best practices to validate vendor provided designs.

  You’ll either pay for a properly designed network with your time or your money when you have to redo the network.

• Best Investment You Can Make
