A wireless site survey is recommended when implementing a
wireless network. For larger wireless network implementations, a site survey
element is required. For small wireless deployments, having a site survey is
fine, but sometimes the cost of the site survey becomes a problem. When we
implement a wireless network, we seek the best wireless coverage and
performance with minimal use of the equipment. This saves time, labor and
equipment costs. To obtain optimal wireless coverage and return, we must understand
the radio frequency (RF) behavior of our wireless deployment site. A search on
the wireless site will provide this information, revealing where the signal
interference occurs, where the signals are weakest and areas without signs
(dead zones). Wireless search also helps prevent interference from existing
radio sources and interference from physical structures such as columns, beams,
walls and metal objects. Anything can affect the radio signal profile of a
website, including furniture and people. It is important to remember that the
purpose of a wireless Router Survey
is to determine the feasibility of implementing a wireless network to meet your
needs and discover how to implement a wireless network within the limitations
of your site.
How Does A Wireless Site Survey Help
When a wireless
network is deployed, WiFi access points (APs) are usually placed at random, but
is an excellent additional location for the WiFi access point a good strategy?
In small implementations, the ad-hoc approach is not a problem, but with medium
and large deployments, a wireless Rf Site
Survey is recommended, which is usually necessary. A wireless site survey
helps determine where to place Wi-Fi hotspots to avoid interference and
coverage of other hotspots. In practice, many network administrators randomly set
Wi-Fi hotspots and install additional Wi-Fi hotspots when additional coverage
is needed or when they receive complaints about insufficient WiFi access. On a
new wireless network, the network administrator has no idea of the type of
interference and how the radio signal profile of the website changes.
Investigating the wireless website will help determine if there is interference
in the same channel and at what point, where external radio interference is
causing problems, and how to minimize the number of Wi-Fi hotspots. -Fi needed
and where to locate them so ideal WiFI hotspots for better coverage It is
important to understand that a survey of the Wireless Testing Tools website is a snapshot of the radio signal
profile of the website at that time. As the site changes with a new addition of
people, cabins, furniture and electronic equipment, your radio signal profile
changes and may require additional site searches.
What Wifi Standards Need To Be Covered
In A Site Survey
The most common
WiFi standards used include 802.11a, 802.11b, 802.11g, 802.11n, and 802.11ac.
The 802.11b and 802.11g rules apply the 2.4 GHz band and are the most common
supported standards. The difference between the two measures is performance,
with 802.11b that supports 11 Mbps and 802.11g that supports 54 Mbps. The next necessary
measure is the 802.11n standard, which supports the 2.4 GHz and 5 GHz bands and
with improved performance up to 600 Mbps. The latest standard is 802.11ac,
compatible with the 5 GHz band and with an improved throughput of up to 7 Gbit
/ s. It is important to note that many new personal computers (PCs) and tablets
are not compatible with the 802.11n or 802.11ac standard. Many companies can
have a wide range of Wi-Fi devices and must support many generations of Wi-Fi
devices, from 802.11a to 802.11ac and more. A site survey should cover all the
WiFi standards used. Do not assume that a search on the site of one employer is
valid for another.
What Are The Different Types Of Wireless
Site Surveys Used For Site Surveys
There are three
types of passive, active and predictive searches on wireless sites.
A passive
on-site inspection tool listens to existing access points and other signal
sources for signal strength, interference, and access point (AP) coverage. In
passive site searches, listening WiFi adapters do not need to associate with
the AP, they look passively to provide an image of the radio frequency (RF)
characteristics of the network website without thread. Passive searches are
often done when upgrading existing wireless Networks Surveys, such as adding additional access points.
In an active
site search, the WiFi search adapter is associated with the access points. This
allows you to collect detailed information such as network traffic, loss of
performance packets, and data speed. An active site search is usually done in
conjunction with a passive site search at the start of new wireless network
implementation.
A predictive
site survey is performed without any field measurements. It uses RF planning
software tools that can predict wireless coverage of access points. To conduct
this research on-site, it is essential to have a plan (AutoCAD, JPEG, PDF).
Predictive site surveys are used when the site or building has not yet been
constructed and is useful for budgeting purposes.
The purpose of
all wireless site searches is to provide detailed information that covers the
radio frequency coverage of the site. Before implementing or attempting to
optimize a Wireless Design network,
you should understand all possible areas of interference, the location of
access points, power considerations, and necessary cabling requirements. A
survey of a wireless website can provide all of this information and much more.
You, therefore, have the tools you need to design, implement and optimize your
wireless network.
