1. GENERAL1-1 Overview of IEEE 802.11The 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 tooperate within an “ad hoc” or “infrastructure” network, as well as dealing withthe issues related to mobility within those networks. Spread spectrum techniquesare used to tolerate mobility and multipath effects. They are also a requirement forcompliance with FCC, ETSI and those of other regulatory authorities whenoperating within the Industrial, Scientific, and Medical (ISM) frequency band.An ad hoc communications network is created quickly and informally for atemporary time period. An infrastructure network usually requires more planningso that wireless stations can communicate over longer distances through accesspoints, 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 withCollision Avoidance (CSMA-CA) protocol. Using this protocol, each station sensesthe communications medium (RF channel), and does not transmit until the channelis clear. This avoids collisions and minimizes the re-transmission of subsequentpackets.The standard also supports the operation of a station within a wireless LAN thatmay coexist with several overlapping wireless LANs. To accomplish this, a schemeof channelization and spread spectrum techniques is used. Direct Sequence (DSSS)and Frequency Hopping (FHSS) spread spectrum techniques are supported by thestandard and both operate in the 2.4 to 2.4835GHz frequency band (the unlicensedISM band). An infrared technique is also supported for indoor applications. Thestandard supports a 1 and 2Mbps data rate for both DSSS and FHSS and hasrecently introduced a high data rate standard supporting 5.5 and 11Mbps DSSSusing Complementary Code Keying (CCK) modulation.The standard has also specified the requirements and services that enable privateand secure communications to occur.MIRAE TECHNOLOGYFCC ID: O6ANANOSPEEDEXHIBIT #: 7F

3-3 Configuration utilityduring the installation of your Mirae Wireless LAN Card, configuration utility isalso installed. You can see the icon at the right bottom of your screen. Doubleclicking 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 showsthe identification MAC address of the BSS to which this is connected currently.Current Channel : Channel number is the channel available for the Communications between the clients and AP or between the clients only. In case of theInfrastructure Network Mode, the channel number is scanned automatically (Neednot to worry about setting the channel number), while in case of the Ad-hocNetwork Mode; the channel number is set by the client and can be changed by theclient later.Link Quality : This is the measure of the radio link.Signal Strength : This is the measure of the signal Strength. The measured signalStrength gives the overall Link Quality and Connection Status.You can change the configuration by clicking on the Configuration Change. Whenyou click on the Configuration Change, you see the screen given below.MIRAE TECHNOLOGYFCC ID: O6ANANOSPEEDEXHIBIT #: 7K
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 ofAP.Ethernet : The default is RFC1042. You can also choose Encapsulation.TX Rate : The transmission rate at which the data packets are transmitted by theclient or AP. You can set this to Auto select 1 or 2 Mbps, Fixed 1 Mbps, Fixed2 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 towhich may cause the undesired results.WEP Required : WEP stands for Wired Equivalent Privacy. WEP is an encryptionscheme that provides the secure wireless data communications to the users. WEPuses a 40-bit key to control the network access. In order to decode the datatransmission, 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 NetworkMIRAE TECHNOLOGYFCC ID: O6ANANOSPEEDEXHIBIT #: 7LMIRAE TECHNOLOGYFCC ID O6ANANOSPEED
Mode, the change in the channel number is effective. In case of the InfrastructureNetwork Mode, changing the channel number is of no concern as the channel isscanned automatically. Please see the table for the requirements of differentcountries and the channel frequency.After changing the settings in the Configuration Change Dialog box, click onApply Changes. It takes a few seconds to set the changes that you made. Then youcan 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. Thiskey 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 tocontact/share the resources must type the same key. The WEP key works in theinfrastucture mode only. There are two option in case of the WEP. You can selecteither of Disable, and Mandatory. If you select Disabled, the communicationsbetween clients and clients and AP is not secure. If you select mandatory, you needto setup the AP also and enter the same Key for communicating other clientsassociated with the AP or with AP itself.
WEP Key Generation : There are two ways of generating the WEP key. The first isby entering any text in the Passphrase. And click on Generate. It will generate fourWEP keys Key 1, Key 2, Key 3, and Key 4. You can select any key for the security.If you do not select any Key, Key 1 is selected, as it is default key. Then click onWrite and it will update the registry and driver.Another WEP key generation method is by inserting the Key values directly fromthe keyboard. And click on the Write to update driver and registry. Select the Keynumber and use that Key for accessing the Access Point. If the Key is not enteredcorrectly, a client cannot access the resources. This Key value protects the illegalaccess to the wireless network resources. As the wireless channel is more prone tothe illegal access, WEP provides the users safe access.Warning : Use of the WEP key makes your data secure but there is degradation inthe throughput performance when we employ the WEP key.MIRAE TECHNOLOGYFCC ID: O6ANANOSPEEDEXHIBIT #: 7N
