Aironet Wireless Client Typographical Conventions When reading the technical reference manual, it’s important to under- stand the symbol and formatting conventions used in the documentation. The following symbols and formatting are used in the manual. Convention Type of Information Indicates a note which contains important information set off from the normal text.
The Aironet Wireless Client operates by associating to an Access Point or Bridge to make a connection to remote end nodes. If two end nodes are both Aironet Wireless Clients and they are within radio range of each other, the units may be configured to send the radio packets directly to each other without connecting to an intervening Access Point or Bridge.
Aironet Wireless Client There are two common applications for the Serial Client: Replacing a serial cable with a wireless link. The cable between a serial device and its host can be eliminated. NOTE: For this application, two Wireless Clients are required.
The Aironet Wireless Client transports data packets transparently as they move through the wireless infrastructure. The Aironet Wireless Client is also protocol independent for all packets, except those either addressed specifically to the Aironet Wireless Client or sent as multicast address packets.
The 3500 Series uses a radio modulation technique known as Frequency Hopping Spread Spectrum transmission (FHSS). It combines high data throughput with excellent immunity to interference. The Aironet Wire- less Client operates in the 2.4 GHz license-free Industrial Scientific and Medical (ISM) band.
This can be configured either as two separate remote antennas or as the single unit diversity antenna supplied by Aironet. Two antennas allow the 3500 Series to detect and use the strongest signal coming from either of the anten- nas.
Technology, previously developed for military “anti-jamming” and “low probability of intercept” radio systems. The Aironet Wireless Client must be set to the same System Identifier (SSID) as all other Aironet devices on the wireless infrastructure. Units with a different SSID will not be able to directly communicate with each...
Access Point on the infra- structure including repeaters and client nodes. Cell – A single Aironet Wireless Client transmits and receives data within an area called a cell. A cell is the area of radio range (coverage) in which the Aironet Wireless Client can communicate to other devices in the wireless infrastructure.
The Aironet Wireless Client can be used in a variety of infrastructure configurations. How you configure your infrastructure will determine the size of the microcell, which is the area a single Aironet Wireless Cli- ent will provide with RF coverage. You can extend the RF coverage area by creating multiple microcells on a LAN.
Aironet Wireless Client xxv Figure 0.1 - Universal Client or Multi-Clients Connect to an Access Point This is the most common use of the Universal Client. Each device connected to the Universal Client or Multi-Client can communicate with any device in the wired or radio network as well as with those devices attached to other Universal Client or Multi-Clients.
Aironet Wireless Client Figure 0.2 - Ethernet Universal Clients Only If you do not need a wired infrastructure, you may set the Ethernet Universal Clients to connect to each other without the use of an Access Point. Each unit will send packets directly to its intended partner.
Aironet Wireless Client xxvii Figure 0.3 - Serial Universal Clients Only If both ends of the serial connection are to be Serial Universal Clients and they are within radio range of each other, the Serial Universal Clients may be put into a mode to communicate directly with each other without an intervening Access Point.
Aironet Wireless Client Figure 0.4 - Multi-Clients Connected to an Access Point This is the most common use of the Multi-Client. Up to four nodes can be con- nected to a single Multi-Client (through the crossover part of a hub) in an Ethernet infrastructure.

(a CTS) before the originator may send the real data packet. A node at the far end of a cell will see the RTS to/from the Aironet Wireless Client or the CTS to/from the Aironet Wireless Client. The node will know how long to block its transmitter to allow the real packet to be received by the Aironet Wireless Client.
Running a Signal Strength Test (Strength) The strength option sends a packet once per second to the parent Access Point. This packet is echoed back to the Aironet Wireless Client which records and displays the RF signal strength associated with that particu- lar node.
4 - 8 Aironet Wireless Client Configuration Radio Install Linktest Menu Option Value Description 1 - Multicast - Run a multicast test 2 - Unicast - Run a unicast test 3 - Remote - Run a remote test 4 - Destination...
Running A Unicast Test (Unicast) The unicast option can be used to test the path between the Aironet Wireless Client and any other Aironet node in the wired or radio net- work. The packets are sent with the same error recovery as normal user data so round trip times indicate the infrastructure throughput and con- gestion.
The destination option is used to indicate the target node address for the link test. You may enter an infrastructure address or the string “any”. If you select “any”, the Aironet Wireless Client will direct the test to the Access Point to which the unit is associated. If you enter a infrastructure address it may only be used for the remote or unicast linktests.
Configuring the Radio Network 4 - 11 Viewing Errors (Errors) The errors option is used to view the Radio Error statistics that may have occurred during the link test. See Chapter 8 “Viewing Statistics”. Setting the Automatic Link Test Mode (Autotest) The autotest option is used to control the automatic running of a link test whenever a repeater associates to its parent.

The parentid parameter is used to control to which address the unit asso- ciates. If the value is set to “any”, the Aironet Wireless Client will asso- ciate with its best choice of parent based on signal quality and load. If the value is set to an infrastructure address, the Aironet Wireless Client will only associate with the matching address.
The unit will then begin scanning for a new parent. Use the retry count field if the Aironet Wireless Client is mobile and you want to move from Aironet Wireless Client to Aironet Wireless Client very quickly after moving out of range.
Configuring the Radio Network 4 - 15 Setting Fragment Size (Fragment) This parameter determines the largest packet size that may be transmit- ted. Packets that are larger than this size will be broken into pieces that are transmitted separately and rebuilt on the receiving side. If there is a lot of radio interference or collisions with other nodes, the smaller lost packets can be retried faster and with less impact on the air- waves.
Chapter 5 - Configuring the Ethernet or Serial Port C H A P T E R 5 Configuring the Ethernet or Serial Port This chapter describes the procedures for configuring the Aironet Wire- less Client’s Ethernet or Serial Port. Here’s what you’ll find in this chapter: Using the Configuration Menu...

On the Unix host, the Syslogd deamon process will usually add the cur- rent time and IP address of the unit that sent the log. The Aironet Wire- less Client will pre-pend its own name to the log before it is sent.
C H A P T E R 1 1 Performing Diagnostics This chapter describes how to use the Diagnostics Menu to maintain the Aironet Wireless Client. Here’s what you’ll find in this chapter: Using the Diagnostics Menu Starting a Telnet Session...
Running a Linktest (Linktest) Use the linktest option to test the quality of the radio transmission between the Aironet Wireless Client and other nodes on the radio net- work. See “Running a Linktest” in Chapter 4. Restarting the Unit (Restart) Use the restart option to reboot the Aironet Wireless Client.
If the connection is to be made to another Aironet unit which has not been assigned an IP address, start the connection using the MAC level infrastructure address of the unit. This connection uses a proprietary protocol which is not routable.
Typing the escape sequence of characters as defined by the escape option in the Diagnostics Menu. See “Changing the Escape Sequence”. If the remote node is an Aironet node, choose the close option which is accessible on the Console Port Main Menu during a telnet session only.
Use a dollar sign “$” followed by two hexadecimal numbers Physically Locating a Unit (Find) Use the find option to blink the amber indicators of the Aironet Wireless Client on and off. Find a unit you can telnet to if you are not sure of it’s exact location.
Loading New Code Versions (Load) The Aironet Wireless Client code is stored in a flash memory chip inside the unit. Use the load option to load new code versions of the Aironet Wireless Client’s firmware and save it to flash memory.
Performing Diagnostics 11 - 7 Downloading Using Xmodem Protocol (Xmodem/Crc-xmodem) Use the Xmodem or CRC-xmodem options to load the new firmware ver- sion through the Console Port. Depending on the communications software programs available, choose: Xmodem: Terminates packets with a “checksum” CRC-xmodem: Terminates packets with a Cyclic Redundancy Check (CRC).

Distributing Firmware or Configuration (Distribute) Use the distribute option to send the firmware or configuration from one Aironet Wireless Client to all other Aironet Wireless Clients on the infrastructure. By using the distribute option the time needed to perform firmware upgrades or make global changes to the configuration is greatly decreased.
Page 149
Performing Diagnostics 11 - 13 If the distribute is done without a password, the load will be ignored by remote units with a configured password. If a remote unit does not have a password and firmware is being distributed, it only accepts the load based on the version number and code checksum.
