1.Introduction
Wireless Display Tester is a portable tool that helps users find the best Wi-Fi channel and probe
interference levels (noise floor) in the installation and troubleshooting of network fault areas to
help with installation troubleshooting, analysis and testing of residential and Small and
medium-sized business (SMB) Wi-Fi network. This rugged handheld device is designed to operate
in stand-alone mode and does not require connection to an access point (AP) and the installer to
easily identify the best signal strength of the Wi-Fi device. This will help the installer decide which
channel to use, detect strong/weak Wi-Fi signals, and determine the level of interference in the
area. Another application is to identify the location of the "Signal Enhancer" and the Grid Add-on.
The Wireless Display Tester operates on 802.11b/g/n networks in the 2.4 GHz band and
802.11a/n/ac networks in the 5 GHz band.
The product will be designed as a simplified, handheld "qualified/failed" device and standardized
test instrument for use by Level 1 / field technicians. It provides technicians with a less complex
graphical representation of the home or SMB radio frequency (RF) environment with key
parameters for successful Wi-Fi network installations on the 2.4 GHz and 5 GHz ISM spectrum.
Using color-coded "PASS (green)" and "failed" (red) bands (scopes that can be defined by
corporate policies) will show the channels available to the technician and the level of interference
that may be present in the immediate area. The design of the device will include a "sturdy" shell
with a hardened glass surface.
The product contains a long-life lithium-ion battery for the purpose of field technicians operating
under normal conditions for at least four hours without charging.The core features and shell are
unique to the market that provides cost-effectiveness, and you can make a fast decisions and
diagnoses through failure showing.When combined with an external scorecard, the technician is
also able to record the installation environment for use in future service commissioning when the
environment may change. The device is also intended to be used with the arrangement of signal
boosters to optimize Wi-Fi signal performance in the environment.
