Wireless LAN network defined by IEEE 802.11ac/a/b/g standard committee
Could be configured as:
Ad Hoc wireless LAN – (Win10 is not available)
Infrastructure wireless LAN.
Ad Hoc network is a group of PCs installed with wireless LAN cards; this group
of PCs is called a BSS (Basic Service Set). PCs in this group can use their
wireless LAN cards to communicate with each other, but can not connect to the
Internet.
Ad Hoc Wireless Network Infrastructure Wireless Network
The most obvious difference between Infrastructure wireless network and Ad
Hoc wireless network is that the PCs in Infrastructure wireless network can
access the resource in the Internet through Access Point.
Depending on your requirement, you can easily set up your PC’s network to be
a “Ad Hoc” or “Infrastructure” wireless network. Generally speaking, if in your
network, there is an Access Point in it, we recommend you to set your
network as an “Infrastructure”, so it can connect to the Internet.

To use the WLAN 11ac USB Client Adapter with a computing device, the
WLAN and Bluetooth Combo Adapter must be equipped with a proper Interface.
All drivers and supporting software for the WLAN Adapter must be installed and
configured first.
Ask your system administrator for the following information, which
you may need to provide during driver installation :
Your Wireless Client Name.
Your Wireless SSID.
Your computer’s unique client name and workgroup name. For your
network account, your user name and password.
Your IP address, gateway address, and subnet mask if you’re not
using a DHCP client.
Any computer on a network is identified by a unique network address. There
are two methods to assign a network address to a computer on a TCP/IP
network :
Static IP addressing.
Dynamic IP addressing (DHCP Client).
In network with static IP addressing, the network administrator manually
assigns an IP address to each computer. Once a static IP address is assigned,
a computer uses the same IP address every time it reboots and logs on to the
network. You may manually change the IP address in the
dialog box.
Network using static IP address is easy to set up and do not
Network Properties
require additional network management software.
In network with dynamic IP addressing, a DHCP server in the network
dynamically assigns IP addresses to all clients every time they log on to the
network. Network using dynamic IP address requires setting up and running a
DHCP Server.

IEEE 802.11 Standard
The IEEE 802.11 Wireless LAN standards subcommittee, which is formulating
a standard for the industry.
Access Point
An internetworking device that seamlessly connects wired and wireless
networks together.
Ad Hoc
An Ad Hoc wireless LAN is a group of computers, each with a WLAN
adapter, connected as an independent wireless LAN. Ad Hoc wireless LAN
is applicable at a departmental scale for a branch or SOHO operation.
BSSID
A specific Ad Hoc LAN is called a Basic Service Set (BSS). Computers in a
BSS must be configured with the same BSSID.
DHCP
Dynamic Host Configuration Protocol - a method in which IP addresses are
assigned by server dynamically to clients on the network. DHCP is used for
Dynamic IP Addressing and requires a dedicated DHCP server on the
network.
Direct Sequence Spread Spectrum
This is the method the wireless cards use to transmit data over the frequency
spectrum. The other method is frequency hopping. Direct sequence
spreads the data over one frequency range (channel) while frequency
hopping jumps from one narrow frequency band to another many
times per second.
ESSID
An Infrastructure configuration could also support roaming capability for
mobile workers. More than one BSS can be configured as an Extended
Service Set (ESS). Users within an ESS could roam freely between BSSs
while served as a continuous connection to the network wireless stations
and Access Points within an ESS must be configured with the same ESSID
and the same radio channel.
Ethernet
Ethernet is a 10/100Mbps network that runs over dedicated home/office
wiring. Users must be wired to the network at all times to gain access.
Gateway
A gateway is a hardware and software device that connects two dissimilar
Page 24
22
systems, such as a LAN and a mainframe. In Internet terminology, a gateway
is another name for a router. Generally a gateway is used as a funnel
for all traffic to the Internet.
IEEE
Institute of Electrical and Electronics Engineers
Infrastructure
An integrated wireless and wired LAN is called an Infrastructure
configuration. Infrastructure is applicable to enterprise scale for wireless
access to central database, or wireless application for mobile workers.
ISM Band
The FCC and their counterparts outside of the U.S. have set aside bandwidth
for unlicensed use in the so-called ISM (Industrial, Scientific and
Medical) band. Spectrum in the vicinity of 2.4 GHz, in particular, is being
made available worldwide. This presents a truly revolutionary opportunity
to place convenient high-speed wireless capabilities in the hands of users
around the globe.
Local Area Network (LAN)
A LAN is a group of computers, each equipped with the appropriate network
adapter card connected by cable/air, that share applications, data,
and peripherals. All connections are made via cable or wireless media,
but a LAN does not use telephone services. It typically spans a single
building or campus.
Network
A network is a system of computers that is connected. Data, files, and
messages can be transmitted over this network. Networks may be local or
wide area networks.
Protocol
A protocol is a standardized set of rules that specify how a conversation
is to take place, including the format, timing, sequencing and/ or error
checking.
SSID
A Network ID unique to a network. Only clients and Access Points that
share the same SSID are able to communicate with each other. This string
is case-sensitive.
Static IP Addressing
A method of assigning IP addresses to clients on the network. In networks
with Static IP address, the network administrator manually assigns an IP
address to each computer. Once a Static IP address is assigned, a computer
Page 25
23
uses the same IP address every time it reboots and logs on to the
network, unless it is manually changed.
Temporal Key Integrity Protocol (TKIP)
The Temporal Key Integrity Protocol, pronounced tee-kip, is part of the
IEEE 802.11i encryption standard for wireless LANs. TKIP is the next
generation of WEP, the Wired Equivalency Protocol, which is used to
secure 802.11 wireless LANs. TKIP provides per-packet key mixing, a
message integrity check and a re-keying mechanism, thus fixing the
flaws of WEP.
Transmission Control Protocol / Internet Protocol (TCP/IP)
TCP/IP is the protocol suite developed by the Advanced Research
Projects Agency (ARPA). It is widely used in corporate Internet works,
because of its superior design for WANs. TCP governs how packet is
sequenced for transmission the network. The term “TCP/IP” is often
used generically to refer to the entire suite of related protocols.
Transmit / Receive
The wireless throughput in Bytes per second averaged over two seconds.
Wi-Fi Alliance
The Wi-Fi Alliance is a nonprofit international association formed in 1999
to certify interoperability of wireless Local Area Network products based
on IEEE 802.11 specification. The goal of the Wi-Fi Alliance’s members is
to enhance the user experience through product interoperability. The
organization is formerly known as WECA.
Wi-Fi Protected Access (WPA)
The Wi-Fi Alliance put together WPA as a data encryption method for
802.11 wireless LANs. WPA is an industry-supported, pre-standard version
of 802.11i utilizing the Temporal Key Integrity Protocol (TKIP),
which fixes the problems of WEP, including using dynamic keys.
Wide Area Network (WAN)
A WAN consists of multiple LANs that are tied together via telephone
services and / or fiber optic cabling. WANs may span a city, a state, a
country, or even the world.
Wired Equivalent Privacy (WEP)
Now widely recognized as flawed, WEP was a data encryption method
used to protect the transmission between 802.11 wireless clients and
APs. However, it used the same key among all communicating devices.
WEP’s problems are well-known, including an insufficient key length and
no automated method for distributing the keys. WEP can be easily
Page 26
24
cracked in a couple of hours with off-the-shelf tools.
Wireless LAN (WLAN)
A wireless LAN does not use cable to transmit signals, but rather uses
radio or infrared to transmit packets through the air. Radio Frequency
(RF) and infrared are the commonly used types of wireless transmission.
Most wireless LANs use spread spectrum technology. It offers limited
bandwidth, usually under 11Mbps, and users share the bandwidth with
other devices in the spectrum; however, users can operate a spread
spectrum device without licensing from the Federal Communications
Commission (FCC).
Fragment Threshold
The proposed protocol uses the frame fragmentation mechanism defined in
IEEE 802.11 to achieve parallel transmissions. A large data frame is
fragmented into several fragments each of size equal to fragment threshold.
By tuning the fragment threshold value, we can get varying fragment sizes.
The determination of an efficient fragment threshold is an important issue in
this scheme. If the fragment threshold is small, the overlap part of the master
and parallel transmissions is large. This means the spatial reuse ratio of
parallel transmissions is high. In contrast, with a large fragment threshold, the
overlap is small and the spatial reuse ratio is low. However high fragment
threshold leads to low fragment overhead. Hence there is a trade-off between
spatial re-use and fragment overhead.
Fragment threshold is the maximum packet size used for fragmentation.
Packets larger than the size programmed in this field will be fragmented If you
find that your corrupted packets or asymmetric packet reception (all send
packets, for example). You may want to try lowering your fragmentation
threshold. This will cause packets to be broken into smaller fragments. These
small fragments, if corrupted, can be resent faster than a larger fragment.
Fragmentation increases overhead, so you'll want to keep this value as close
to the maximum value as possible.
RTS (Request To Send) Threshold
The RTS threshold is the packet size at which packet transmission is governed
by the RTS/CTS transaction. The IEEE 802.11-1997 standard allows for short
packets to be transmitted without RTS/CTS transactions. Each station can
have a different RTS threshold. RTS/CTS is used when the data packet size
exceeds the defined RTS threshold. With the CSMA/CA transmission
Page 27
25
mechanism, the transmitting station sends out an RTS packet to the receiving
station, and waits for the receiving station to send back a CTS (Clear to Send)
packet before sending the actual packet data. This setting is useful for
networks with many clients. With many clients, and a high network load, there
will be many more collisions. By lowering the RTS threshold, there may be
fewer collisions, and performance should improve. Basically, with a faster RTS
threshold, the system can recover from problems faster. RTS packets
consume valuable bandwidth, however, so setting this value too low will limit
performance.
Beacon Interval
In addition to data frames that carry information from higher layers, 802.11
includes management and control frames that support data transfer. The
beacon frame, which is a type of management frame, provides the "heartbeat"
of a wireless LAN, enabling stations to establish and maintain communications
in an orderly fashion. Beacon Interval represents the amount of time between
beacon transmissions. Before a station enters power save mode, the station
needs the beacon interval to know when to wake up to receive the beacon
(and learn whether there are buffered frames at the access point).
Preamble Type
There are two preamble types defined in IEEE 802.11 specification. A long
preamble basically gives the decoder more time to process the preamble. All
802.11 devices support a long preamble. The short preamble is designed to
improve efficiency (for example, for VoIP systems). The difference between the
two is in the Synchronization field. The long preamble is 128 bits, and theshort
is 56 bits.
WPA2
It is the second generation of WPA. WPA2 is based on the final IEEE 802.11i
amendment to the 802.11 standard.
Temporal Key Integrity Protocol (TKIP)
The Temporal Key Integrity Protocol, pronounced tee-kip, is part of the IEEE
802.11i encryption standard for wireless LANs. TKIP is the next generation of
WEP, the Wired Equivalency Protocol, which is used to secure 802.11 wireless
LANs. TKIP provides per-packet key mixing, a message integrity check and a
re-keying mechanism, thus fixing the flaws of WEP.
Page 28

802.1x Authentication
802.1x is a framework for authenticated MAC-level access control, defines
Extensible Authentication Protocol (EAP) over LANs (WAPOL). The standard
encapsulates and leverages much of EAP, which was defined for dial-up
authentication with Point-to-Point Protocol in RFC 2284.
Beyond encapsulating EAP packets, the 802.1x standard also defines EAPOL
messages that convey the shared key information critical for wireless security.
Advanced Encryption Standard (AES)
Security issues are a major concern for wireless LANs, AES is the U.S.
government’s next-generation cryptography algorithm, which will replace DES
and 3DES.

and, if not installed and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception, which can be determined by turning
the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following
measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
-Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
-Consult the dealer or an experienced radio/TV technician for help.
NOTE 2: Any changes or modifications to this unit not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment.
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. End users
must follow the specific operating instructions for satisfying RF exposure compliance.
Note 1: This module certified that complies with RF exposure requirement under mobile or fixed condition, this
module is to be installed only in mobile or fixed applications.
A mobile device is defined as a transmitting device designed to be used in other than fixed locations and to
generally be used in such a way that a separation distance of at least 20 centimeters is normally maintained
between the transmitter's radiating structure(s) and the body of the user or nearby persons. Transmitting devices
designed to be used by consumers or workers that can be easily re-located, such as wireless devices associated
with a personal computer, are considered to be mobile devices if they meet the 20 centimeter separation
requirement.
A fixed device is defined as a device is physically secured at one location and is not able to be easily moved to
another location.
Note 2: Any modifications made to the module will void the Grant of Certificatio n, t his module is limited to OEM
installation only and must not be sold to end-users, end-user has no manual instructions to remove or install the
device, only software or operating procedure shall be placed in the end-user operating manual of final products.

Note 3: Additional testing and certification may be necessary when multiple modules are used.
Note 4: The module may be operated only with the antenna with which it is authorized. Any antenna that is of the
same type and of equal or less directional gain as an antenna that is authorized with the intentional radiator may be
marketed with, and used with, that intentional radiator.
Note 5: To ensure compliance with all non-transmitter functions the host manufacturer is responsible for ensuring
compliance with the module(s) installed and fully operational. For example, if a host was previously authorized as
an unintentional radiator under the Supplier’s Declaration of Conformity procedure without a transmitter certified
module and a module is added, the host manufacturer is responsible for ensuring that the after the module is
installed and operational the host continues to be compliant with the Part 15B unintentional radiator requirements.
Since this may depend on the details of how the module is integrated with the host, LM Technologies Ltd. shall
provide guidance to the host manufacturer for compliance with the Part 15B requirements.
Note 6: FCC ID label on the final system must be labeled with “Contains FCC ID: VVXLM813” or “Contains
transmitter module FCC ID: VVXLM813”.
