4.3.9 Virtual WiFi
Click the check box of “Virtual WiFi disallowed” at the bottom of the window to activate Virtual WiFi.
Virtual WiFi , abbreviated to VWiFi, is a software layer that abstracts the wireless LAN card
hardware into multiple virtual adapters. The software handles the connections of each adapter to
ensure every adapter has an opportunity to connect to their respective networks limited by time.
And you act as if you have multiple WLAN hardware adapters working independently.

Appendix B: Glossary
802.11b - The 802.11b standard specifies a wireless product networking at 11 Mbps using
direct-sequence spread-spectrum (DSSS) technology and operating in the unlicensed radio
spectrum at 2.4GHz, and WEP encryption for security. 802.11b networks are also referred to
as Wi-Fi networks.
802.11g - specification for wireless networking at 54 Mbps using direct-sequence
spread-spectrum (DSSS) technology, using OFDM modulation and operating in the unlicensed
radio spectrum at 2.4GHz, and backward compatibility with IEEE 802.11b devices, and WEP
encryption for security.
802.11n - 802.11n builds upon previous 802.11 standards by adding MIMO (multiple-input
multiple-output). MIMO uses multiple transmitter and receiver antennas to allow for increased
data throughput via spatial multiplexing and increased range by exploiting the spatial diversity,
perhaps through coding schemes like Alamouti coding. The Enhanced Wireless Consortium
(EWC) was formed to help accelerate the IEEE 802.11n development process and promote a
technology specification for interoperability of next-generation wireless local area networking
(WLAN) products.
Ad-hoc Network - An ad-hoc network is a group of computers, each with a Wireless Adapter,
connected as an independent 802.11 wireless LAN. Ad-hoc wireless computers operate on a
peer-to-peer basis, communicating directly with each other without the use of an access point.
Ad-hoc mode is also referred to as an Independent Basic Service Set (IBSS) or as
peer-to-peer mode, and is useful at a departmental scale or SOHO operation.
DSSS - (Direct-Sequence Spread Spectrum) - DSSS generates a redundant bit pattern for all
data transmitted. This bit pattern is called a chip (or chipping code). Even if one or more bits in
the chip are damaged during transmission, statistical techniques embedded in the receiver can
recover the original data without the need of retransmission. To an unintended receiver, DSSS
appears as low power wideband noise and is rejected (ignored) by most narrowband receivers.
However, to an intended receiver (i.e. another wireless LAN endpoint), the DSSS signal is
recognized as the only valid signal, and interference is inherently rejected (ignored).
Infrastructure Network - An infrastructure network is a group of computers or other devices,
each with a Wireless Adapter, connected as an 802.11 wireless LAN. In infrastructure mode,
the wireless devices communicate with each other and to a wired network by first going
through an access point. An infrastructure wireless network connected to a wired network is
referred to as a Basic Service Set (BSS). A set of two or more BSS in a single network is
referred to as an Extended Service Set (ESS). Infrastructure mode is useful at a corporation
scale, or when it is necessary to connect the wired and wireless networks.
SSID - A Service Set Identification is a thirty-two character (maximum) alphanumeric key
USB 11n Wireless Adapter

identifying a wireless local area network. For the wireless devices in a network to communicate
with each other, all devices must be configured with the same SSID. This is typically the
configuration parameter for a wireless PC card. It corresponds to the ESSID in the wireless
Access Point and to the wireless network name. See also Wireless Network Name and ESSID.
WEP - (Wired Equivalent Privacy) - A data privacy mechanism based on a 64-bit or 128-bit or
152-bit shared key algorithm, as described in the IEEE 802.11 standard. To gain access to a
WEP network, you must know the key. The key is a string of characters that you create. When
using WEP, you must determine the level of encryption. The type of encryption determines the
key length. 128-bit encryption requires a longer key than 64-bit encryption. Keys are defined by
entering in a string in HEX (hexadecimal - using characters 0-9, A-F) or ASCII (American
Standard Code for Information Interchange – alphanumeric characters) format. ASCII format is
provided so you can enter a string that is easier to remember. The ASCII string is converted to
HEX for use over the network. Four keys can be defined so that you can change keys easily.
Wi-Fi - A trade name for the 802.11b wireless networking standard, given by the Wireless
Ethernet Compatibility Alliance (WECA, see http://www.wi-fi.net), an industry standards group
promoting interoperability among 802.11b devices.
WLAN - (Wireless Local Area Network) - A group of computers and associated devices
communicate with each other wirelessly, which network serving users are limited in a local
area.
WPA - (Wi-Fi Protected Access) - A wireless security protocol use TKIP (Temporal Key
Integrity Protocol) encryption, which can be used in conjunction with a RADIUS server
