What is a wireless predictive survey?
Predictive wireless surveys are virtual surveys that are used to plan the deployment of a WiFi network using information about the site where the network will be installed.
How do you survey a WiFi site?
When conducting a wireless site survey, consider the following:
- Understand the wireless requirements.
- Obtain a facility diagram.
- Visually inspect the facility.
- Assess existing network infrastructure.
- Identify coverage areas.
- Determine preliminary access point locations.
- Verify access point locations.
- Document findings.
Which is the WiFi site survey tool?
ManageEngine WiFi Analyzer and Surveyor Free Android app that can help administrators stay on top of their WiFi networks while on the go. Excellent performance for a “small” tool.
What are the different types of wireless site surveys?
There are three main types of wireless site surveys: passive, active, and predictive. During a passive survey, a site survey application passively listens to WLAN traffic to detect active access points, measure signal strength and noise level.
Which type of site survey requires a specialized WiFi adapter?
In an active site survey, the survey WiFi adapter is associated to the AP(s). This allows gathering of detailed information such as network traffic, throughput packet loss, and data rates. An active site survey is often performed in conjunction with a passive site survey at start of a new wireless network deployment.
How a wireless survey should be conducted?
Typically, WiFi site surveys are conducted using a WiFi site survey software application that collects various WiFi signal metrics and analyzes them. Before a survey, an area map is imported the software application, which then overlays the gathered data on top of it.
Why are jamming attacks generally rare?
Jamming attacks generally are rare because sophisticated and expensive equipment is necessary to flood the RF spectrum with enough interference to impact the network. An IEEE 802.11 security protocol that relies on a minimum of 64-bit shared secret key that is known only by the wireless client and the AP.
What are three wireless device tools that can be used to perform a basic site survey?
What are the different types of Wireless Site Surveys used for site surveys? There are basically three types of wireless site surveys passive, active, and predictive. A passive site survey tool listens to existing access points and other signal sources for signal strength, interference, and access point (AP) coverage.
When should a wireless site survey be conducted?
Remember that doing a wireless site survey once is not enough. Rather, they must be done periodically. Your radio environment can change as Bluetooth keyboards and headsets come and go, as microwave ovens turn on and off, and as all sorts of other wireless devices pollute the 802.11 spectrum.
What is the difference between a active site survey and a passive site survey?
Passive surveys collect information about all the signals in the environment after the site is built. Active surveys focus on a specific signal or set of signals while the network is in full operation.
What is the first step that you should perform when performing a wireless site survey?
Typically the first step of a wireless LAN site survey is to gather the necessary business requirements. Interviewing managers and users is the next step, followed by determining RF coverage and documenting existing networks. Installing access points is one of the final steps.
