SITE SURVEY

Wireless Site Surveys And Spectrum Analysis

BSC is equipped to provide you with professional level wireless site surveys and spectrum analysis. A wireless site survey is the process of planning and designing a wireless network to provide a solution that will deliver the required wireless coverage, data rates, network capacity, roaming capability and Quality of Service desired by the client.

The survey usually involves a site visit to test for RF interference and to identify optimum installation locations for access points. This requires analysis of site locations, building floor plans, inspection of the facility and use of site survey tools.

Site surveys are often conducted for the following designs:

  • Point-to-Point (PTP) License-Exempt Wireless and Licensed Microwave Links
  • Point-to-Multipoint (PtMP) Wireless Links and Mesh Networks
  • Indoor/Outdoor Wireless LAN networks

Each of these solutions has specific performance characteristics and design criteria. Your specific application will dictate which solution or combination of these is appropriate to meet your requirements.

In order for us to provide a cost estimate and feasibility assessment for your project, BSC engineers require some basic information to start the process. Please use the following links and forms to submit your request.

Coverage Maps

Wireless surveys display and record information from all the key areas of a wireless network including received signal strengths, access point locations, RF interference and noise levels. The reported information enables optimisation of ‘access point’ channels choices of antenna’s, AP transmit power levels and locations creating a more effective wireless network.

Unique software and techniques work in any environment, supporting all WiFi (IEEE 802.11a/b/g/n/ac) networks.

If required a wireless network prediction is performed in mapping out RF coverage of offices, saving the cost of initial wireless network viability analysis.

Spectrum Analysis / RF Interference

A full spectrum analysis will include detection, measure and recording of the presence of RF Interference that could degrade the performance of a wireless network. Interference such as microwaves, PIR sensors, Bluetooth and legacy wireless devices can have a profound impact on a wireless network.

  • RF Interference
  • Measurement of SNR
  • RF power peaks
  • WiFi Channel interference
  • WiFi Channel Overlap

Wireless site surveys include the following:

  • Detection, measure and recording of the presence of RF Interference that could degrade the performance of a wireless network.
  • Calculate the WiFi supported data rates that can be expected throughout the premises.
  • Access point locations
  • Wireless bridge locations
  •  Antenna’s and other wireless equipment.
  • Co-location of WiFi access points with channel selection and reuse.
  • Information such as; antenna selection, orientation and polarisation.
  • Look for signs of, reflection, refraction, multipath, hidden nodes, dead spots etc.

Wireless site survey documentation includes:

  • Detailed information on the data gathered from the survey
  • Photographs the location of all wireless equipment.
  • Maps of the WiFi RF coverage.
  • Details of RF interference.
  • WiFi Equipment list.
