Site Survey

Site survey
A good site survey will help determine the following: Feasibility of the desired coverage, Radio frequency interference, Wired connectivity limitations.
Before installing the system, asite survey should be performed in order to determine the optimum utilization of networking components and to maximize range, coverage, and infrastructure performance

The process of performing asite survey includes the following steps:
* Gather tools and configuration.
* Research and investigate industry specific concerns.
* Gather the recommended equipment list, or site surveykit.
* Implement the site survey.
* Document the site survey.

It is important for a site survey engineer to accomplish the following: * Be prepared to answer questions * Dressappropriately * Instill a sense of confidence in the customer * Wear or carry company credentials * Have business cards available * Bring the proper equipment |

The four main designrequirements for a WLAN solution are as follows:
* High availability
* Scalability
* Diagnostic tools
* Interoperability

In order to determine where to place the APs, it is important tofind out how much throughput the users will require. Bandwidth requirements for wireless connectivity will potentially determine the number of APs that need to be used. 

Remember the following:* If all devices operate at the same data rate, they will all take the same amount of time to send the same size packets.
* If some devices are operating at higher speeds, then the packet willtransfer faster. This will allow the RF to be available more quickly for the next device waiting to send data.
* If an attempt is made to reduce throughput to a given site by lowering the bridgespeed, this will also affect the high-speed bridges.

Its important for a site survey engineer to know about safety regulation like The National Fire Protection Agency (NFPA), it develops,...
