Hire a Freelance Wireless Site Survey Specialist
are conducted using devices and software that
collect and analyses WLAN metrics and RF spectrum properties. Valid range is
set defining the area in which wireless network engineer jobs connectivity is required.
During the survey, a surveyor walks the facility with a portable computer that
continuously records data. Each location surveyed is marked manually or through
GPS and these statistics are collected:
- Signal
Strength run.
- Noise
(electrical, not audio)
- Signal
to Noise Ratio (SNR) – (This determines the minimum signal needed for
given applications to run effectively)
- Bandwidth
After these parameters are collected they are analysed with specialised software.
Types
of Wireless Site Surveys:
There are three types of site survey in which a specialist
performs:
- Passive:
In this type of survey, WLAN traffic is monitored to detect possible
access points and measure the signal strength and noise level.
- Active:
During the active survey wireless adapters are associated with multiple
access points. The active survey checks the performance post-deployment
the wireless network. If any error is found for data transfer, then it can
be fixed.
- Predictive:
In this type of survey, the RF modeling is created using mockup tools.
Virtual access points are placed on the given area of the network to
estimate the expected coverage.
