Wireless LAN site surveys

The implementation of a wireless network is anything but an easy exercise.  A thorough knowledge of Wireless LAN applications, their requirements and RF planning is required.  Due to the complexity of RF (Radio Frequency) planning we entrust this job to our most experienced personnel.Often underestimated, the site survey plays an important part in the successful deployment of a Wireless LAN project. Only a site survey can ensure how many wireless access points (AP’s) are needed, and where and how the access points have to be installed.  The site survey also determines if external antennas will be necessary and/or additional mounting accessories to ensure a smooth and correct installation of the access points and antennas.

A site survey implies more than just a visit to your location.  The environment has to be measured using wireless tools and professional software to determine an optimal RF design. The site survey will also check for interference sources such as rogue signals and rogue access points.  Additionally, a spectrum analysis will be conducted to detect non-Wi-Fi interference that may interfere with the proper operation of the wireless infrastructure.

The use of a standard site survey design and access point set-up is impossible due to the fact that each location is unique and that each application using the wireless infrastructure will require a specific RF design.

Differences in the RF designs include access point layout patterns, RF cell overlaps as well as specific access point installation methods which will be determined onsite.

When planning a Wireless LAN deployment consideration should be given to the future requirements of the Wireless LAN. Converting a Wireless LAN to support additional services beyond its initial deployment purpose is not simply a matter of adding access points; it can require an additional site survey and the possible relocation of existing access points (including cabling).
