1. GENERAL
1-1 Overview of IEEE 802.11
The IEEE 802.11 specification is a standard for wireless connectivity for fixed,
portable, and moving stations within a local area.
The IEEE 802.11 standard describes the services required by a compliant device to
operate within an “ad hoc” or “infrastructure” network, as well as dealing with
the issues related to mobility within those networks. Spread spectrum techniques
are used to tolerate mobility and multipath effects. They are also a requirement for
compliance with FCC, ETSI and those of other regulatory authorities when
operating within the Industrial, Scientific, and Medical (ISM) frequency band.
An ad hoc communications network is created quickly and informally for a
temporary time period. An infrastructure network usually requires more planning
so that wireless stations can communicate over longer distances through access
points, and may also communicate with existing wired LANs using portals.
The IEEE 802.11 standard describes Media Access Control (MAC) procedures.
The principal method of communication is the Carrier Sense Multiple Access with
Collision Avoidance (CSMA-CA) protocol. Using this protocol, each station senses
the communications medium (RF channel), and does not transmit until the channel
is clear. This avoids collisions and minimizes the re-transmission of subsequent
packets.
The standard also supports the operation of a station within a wireless LAN that
may coexist with several overlapping wireless LANs. To accomplish this, a scheme
of channelization and spread spectrum techniques is used. Direct Sequence (DSSS)
and Frequency Hopping (FHSS) spread spectrum techniques are supported by the
standard and both operate in the 2.4 to 2.4835GHz frequency band (the unlicensed
ISM band). An infrared technique is also supported for indoor applications. The
standard supports a 1 and 2Mbps data rate for both DSSS and FHSS and has
recently introduced a high data rate standard supporting 5.5 and 11Mbps DSSS
using Complementary Code Keying (CCK) modulation.
The standard has also specified the requirements and services that enable private
and secure communications to occur.

1-2 CHARACTERISTIC
• The NS-1100M is wireless LAN adapter cards that provide wireless connection
between computers.
• The NS-1100M is designed to operate with IEEE 802.11 (wireless LAN
International Standard) wireless compliant radio cards and uses a CSMA/CA
(Collision Sense Multiple Access with Collision Avoidance) algorithm as the
media access scheme, which makes high speed communication (with minimal
collision probability) possible.
• The NS-1100M supports DSSS (Direct Sequence Spread Spectrum) physical
layer. This is a radio technique, which scrambles the data prior to transmission
and uses a correlation technique on receiver to improve the signal to noise ratio
and makes it possible to communicate in the office having a wall and a
compartment.
• The NS-1100M for Notebook PC is small and portable as a roaming function is
provided for users who need network services while maintaining mobility.

also installed. You can see the icon at the right bottom of your
screen.
EXHIBIT
#: 7K Double
clicking on that icon will show you the screen as shown below.
State : State explains whether the client is connected to ESS or not. It also shows
the identification MAC address of the BSS to which this is connected currently.
Current Channel : Channel number is the channel available for the Communicat
ions between the clients and AP or between the clients only. In case of the
Infrastructure Network Mode, the channel number is scanned automatically (Need
not to worry about setting the channel number), while in case of the Ad-hoc
Network Mode; the channel number is set by the client and can be changed by the
client later.
Link Quality : This is the measure of the radio link.
Signal Strength : This is the measure of the signal Strength. The measured signal
Strength gives the overall Link Quality and Connection Status.
You can change the configuration by clicking on the Configuration Change. When
you click on the Configuration Change, you see the screen given below.
MIRAE TECHNOLOGY
FCC ID: O6ANANOSPEED
EXHIBIT #: 7L
Configuration Change screen allows you to set the parameters as explained below.
Mode : You can set the Network Mode to Infrastructure or Ad-hoc.
SSID : The SSID can be changed to any value. But that should be the same that of
AP.
Ethernet : The default is RFC1042. You can also choose Encapsulation.
TX Rate : The transmission rate at which the data packets are transmitted by the
client or AP. You can set this to Auto select 1 or 2 Mbps, Fixed 1 Mbps, Fixed
2 Mbps, Fixed 5.5 Mbps, Fixed 11Mbps or Full Auto (1 to 11Mbps).
Important : You must know the TX Rate that your AP can support. Failure to
which may cause the undesired results.
WEP Required : WEP stands for Wired Equivalent Privacy. WEP is an encryption
scheme that provides the secure wireless data communications to the users. WEP
uses a 40-bit key to control the network access. In order to decode the data
transmission, each wireless client on the network must use the identical 40-bit key.
PS Mode : PS stands for Power Saving Mode.
Channel : You can change the channel number. In case of the Ad-hoc Network
MIRAE TECHNOLOGY
Mode, the change in the channel number is effective. In case of the Infrastructure
Network Mode, changing the channel number is of no concern as the channel is
scanned automatically. Please see the table for the requirements of different
countries and the channel frequency.
After changing the settings in the Configuration Change Dialog box, click on
Apply Changes. It takes a few seconds to set the changes that you made. Then you
can visualize the Connection State, Link Quality, Signal Strength respectively.
WEP Security : To provide the secure communication over the wireless medium,
we have provided the WEP key. There are two ways of generating this key. This
key is an important in protecting the illegal access to the wireless networks.
You have to set the key at the Access Point also. And all the users who want to
contact/share the resources must type the same key. The WEP key works in the
infrastucture mode only. There are two option in case of the WEP. You can select
either of Disable, and Mandatory. If you select Disabled, the communications
between clients and clients and AP is not secure. If you select mandatory, you need
to setup the AP also and enter the same Key for communicating other clients
associated with the AP or with AP itself.
WEP Key Generation : There are two ways of generating the WEP
key. The first is
MIRAE TECHNOLOGY
by entering any text in the Passphrase. And click on Generate. It
will generate four
FCC ID: O6ANANOSPEED
WEP keys Key 1, Key 2, Key 3, and Key 4. You can select any key
for the security.
EXHIBIT #: 7N
If you do not select any Key, Key 1 is selected, as it is default key. Then click on
Write and it will update the registry and driver.
Another WEP key generation method is by inserting the Key values directly from
the keyboard. And click on the Write to update driver and registry. Select the Key
number and use that Key for accessing the Access Point. If the Key is not entered
correctly, a client cannot access the resources. This Key value protects the illegal
access to the wireless network resources. As the wireless channel is more prone to
the illegal access, WEP provides the users safe access.
Warning : Use of the WEP key makes your data secure but there is degradation in
the throughput performance when we employ the WEP key.

automatically appear on the Desktop.
5-2 Hardware Installation
Step 1. Ensure that power to the PCMCIA slot is OFF by noting that the PCMCIA
icon does not appear in the System Tray on the Desktop. If unsure, re-boot the
computer.
Step 2. Insert the Wireless LAN Card into the PCMCIA slot.
Step 3. The NS-1100M is a 3.3V only device. Do not therefore force it in a
5V-keyed system as permanent damage may occur.
5-3 Using the PRISM Test Utility (PTU) Software
The Test Utility permits continuous operation of the transmitter. It is therefore
convenient for performing RF measurements such as Transmitter Power. It also
provides a handy method of changing channels within the ISM band, Use of the
Mirae Transmitter Test Utility is basically self explanatory.
An icon was automatically created on the desktop when the Test Utility installation
was performed. It may be run by double-clicking on this icon.
5-4 Using the LANEVAL Software
LANEVAL provides a convenient method of analyzing Packet Error Rate (PER)
and Receiver Sensitivity. An icon for starting LANEVAL was automatically placed
on the desktop when the Test Utility installation was performed.
In order for LANEVAL to form a successful link, the same packet parameters
(e.g., Packet Length, Packet Pad Words, etc.) most be programmed at each end of
the link.
LANEVAL runs in conjunction with the NDC Driver. The Driver permits selection
of Data Rate and Channel. It is normally run in the Pseudo IBSS mode as this
provides a simple wireless Ad Hoc link between two computers. The NDC Driver
may be easily accessed by double-clicking on its.
