bandwidth required for video & audio to 40Mbps. Also, R&D engineers are devoted to the balance between
audio & video quality and transmission bandwidth usage, and further import dynamic encoding techniques to
adjust the compression ratio dynamically in conjunction with the quality of the wireless bandwidth in the
environment.

Wireless Transmission Module System

The Wi-Fi transmission protocol for InstaShow
WPA2 is the best encryption technology for Wi-Fi connection at present stage.
However, existence of vulnerabilities for WPA2 is reported recently: "An attacker in the wireless range of
Wi-Fi network can exploit these vulnerabilities through Key Reinstallation Attack (KRACKs). According
to the research report for KRACKs provided by Mathy Vanhoef, the attack is targeted to the 4-way
handshake mechanism of WPA2 for client equipment (for example, laptops, smart phones or tablets etc.),

system through HDMI interface or pure power supply purposed USB interface.
Wireless transmission module system also passes certifications of RF security regulations of various
countries, such as CE (EN 301 893), FCC (47 CFR FCC Part 15.407), NCC (NCC LP0002), TELEC (ARIB
STD-T71) and so forth.

WAN/LAN Module System

TM
InstaShow is a closed wireless local area commercial display scheme, and Host is not capable of WAN
access. When the WAN port of Host is connected to an enterprise router, the enterprise router provides
Host with access to the Internet. However, any wireless equipment, such as a smart phone or a laptop etc.,
which connects to SSID of Host, cannot access information of Internet through Host, so that external
hackers cannot intrude into the wireless equipment on a client by Host.
The WAN/LAN module of InstaShow
for configuration is Web UI.

Web UI management module system

TM
InstaShow is capable of Web UI management. Web UI can query system status, Wi-Fi settings, system
updates, etc. A device of a user can connect to the SSID of Host through Wi-Fi or connect to Host by using
LAN. The user is required to provide an account and a password to login the home page of Web UI.
