Understanding Application Requirements

Understanding the application requirements for software applications is another important part of a successful wireless deployment. The types and number of applications used will affect the performance and the capacity of an IEEE 802.11 wireless network. Some software applications are very bandwidth intensive and will require more resources than others to perform effectively as designed. Examples of these applications are streaming video, computer-aided design (CAD), and database programs. By contrast, applications used for email, social media (if policy allows), and casual Internet browsing are not bandwidth intensive.

Because digital imaging, graphic design, CAD, and database applications can have a tremendous effect on the performance of a wireless network, they require special attention when the network is designed. The infrastructure resources that will be impacted include the processing power and memory capacity of the wireless access points and the speed of the wired infrastructure itself, such as 100 Mbps or 1,000 Mbps (Gigabit).

This in turn will affect the site survey. The wireless site survey will be impacted because the location where the wireless network is installed may require more infrastructure devices or access points. Other applications, such as Voice over Wireless LAN, may introduce another entire set of issues. This type of deployment may use only the 5 GHz band for wireless voice technology, and therefore the wireless site survey must be performed accordingly.
