Site Survey Consideration


Site Survey Consideration

            There are four major areas to be considered when developing wireless installation design. These should all be considered in terms of future expansion as well as current needs.

1) Range and Coverage
2) Data Rate and Capacity
3) Interference Immunity
4) Connectivity and Power Requirement

The Importance of Site Survey (for LAN)


The Importance of Site Survey (LAN)

The site survey’s primary objective is to ensure mobile workers – the wireless LAN’s “clients”– will not find that the radio frequency signal drops out as they move around the facility, thus becoming disconnected from the host device or other mobile computing devices and their work -- and potentially causing data loss.

The survey also helps customers to clearly understand the impact of the addition of wireless local area networking on their overall networking and system requirements. Important questions it will answer include: Does the existing backbone have adequate bandwidth to handle the overlaid wireless network? In a cellular architecture, are there sufficient resources to include wireless capabilities?

Performing a site survey therefore provides a realistic understanding of the wireless installation. It determines whether a site has unusually high interference issues to resolve, or capacity is greater than anticipated. And an accurate site survey enables accurate quotes to guide financial decision making.
