- It is essential to avoid a trial-and-error installation of your wireless LAN. A proactive, physical approach will identify interference issues and ensure the correct placement of Access Points for optimal performance. 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 multipath 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 you to do this.A site survey helps define the contours of RF coverage in a particular facility. It helps us to discover regions where multipath 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 to choose the number of Wireless devices that a firm needs to meet its business requirements.
A proper site survey provides detailed information that addresses coverage, interference sources, equipment placement, power considerations and wiring requirements. The site survey documentation serves as a guide for network design and for the installation and verification of the Wireless communication infrastructure.
- Importance of a wireless site planning surveyA good wireless system design entails the following:
A site survey
An understanding of the construction of the building
An understanding of where RF coverage is required
The esthetical position (corridors, isles and coverage area blockages)
The number of users per AP
The required throughput per user
The distance from an AP to the LAN’s entry point
Power supply options
The location of the Radius Server (acceptable RTT yes/no)
Understand if the applications are wireless ready
Dimension Network Systems provides a complete site survey which includes a final report document that will be presented to you with suggested hardware list and Access Point placement diagrams to forward onto your cabling contractors.
