2.6.2 Connect the NV-802S and the NV-720D to LAN Devices
In the setup, usually an Ethernet tester serves as a representation of the LAN side as well as a representation of the WAN side.
2.6.3 Run Demos and Tests
The Ethernet tester may send data downstream as well as upstream. It also receives the data in order to check the integrity of
the data transmission. Different data rates can be tested under different line conditions.
2.6.4 Wireless Basics
In recent years, the market for wireless communications has enjoyed tremendous growth. Wireless technology now reaches or
is capable of reaching virtually every location on the surface of the earth. Hundreds of millions of people exchange information
every day via wireless communication products. Anyone can bring a built-in WLAN client Smartphone, tablet or notebook into a
meeting room for a conference without laying a clot of LAN cable or drilling holes everywhere. Wireless LAN enables high
mobility so WLAN users can simultaneously access all LAN facilities just like on a wired LAN as well as Internet access. The
NV-720D is equipped with a wireless LAN interface compliant with the standard IEEE 802.11ac protocol. To boost its
performance even further, the NV-720D is also loaded with an advanced wireless technology to lift up the data rate up to 867
Mbps. You can finally smoothly enjoy a wide range of apps on your smart phone, tablet or smart TV.
What is WEP?
Wired Equivalent Privacy (WEP) is an easily broken security algorithm for IEEE 802.11 wireless networks. Introduced as part of
the original 802.11 standard ratified in September 1999, its intention was to provide data confidentiality comparable to that of a
traditional wired network. WEP, recognizable by the key of 10 or 26 hexadecimal digits, was at one time widely in use and was
often the first security choice presented to users by router configuration tools.
