Safety Information

The FCC with its action in ET Docket 96-8 has adopted a safety standard for human exposure to radio frequency (RF) electromagnetic energy emitted by FCC certified equipment. The Aironet products meet the uncontrolled environmental limits found in OET-65 and ANSI C95.1, 1991.

Proper operation of this radio according to the instructions found in this manual will result in the user exposure to be substantially below the FCC recommended limits.

• Do not touch or move antenna(s) while the unit is transmitting or receiving.

• Do not hold any component containing the radio such that the antenna is very close or touching any exposed parts of the body, especially the face or eyes, while transmitting.

• Do not operate a portable transmitter near unshielded blasting caps or in an explosive environment unless it is a type especially qualified for such use.

• Do not operate radio or attempt to transmit data unless the antenna is connected, if not, the radio may be damaged.

1-2


Snap-On Antenna

Always orient antenna such that it is at least 5 cm

(2 inches) away from your body.

Dipole Antenna

Always orient antenna such that it is at least 15 cm

(6 inches) away from your body.

High Gain Antennas

High gain wall mount or mast mount antennas are designed to be professionally installed and should be located at a minimum distance of 30 cm (12 inches) or more from your body. Please contact your professional installer, VAR, or antenna manufacturer for proper installation requirements.

Warning for Laptop User

In order to comply with the FCC RF exposure limits, it is recommended when using a laptop with the snap-on antenna, that the antenna should not be positioned closer than 5 cm (2 inches) from your body or nearby persons for extended periods of time while it is transmitting (or operating). If the antenna is positioned less than

5 cm (2 inches) from the user, it is recommended that the user limit exposure time.

Radio Characteristics

The PC Card operates in the 2.4 GHz license-free Industrial

Scientific and Medical (ISM) band. Data is transmitted over a half-duplex radio channel operating up to 2 Megabits per second (Mbps) for the PC4500 or up to 11 Mbps for the

PC4800.

Direct Sequence Radio Technology

The Aironet 4000 Series Wireless LAN Adapter uses Direct

Sequence Spread Spectrum (DSSS) transmission previously developed for military “anti-jamming” and “low probability of intercept” radio systems. The signal is transmitted over a wide frequency range, using multiple frequencies simultaneously. This protects the data transmission from interference.

If a particular frequency encounters a level of noise and/or interference, there is enough redundancy built into the signal on other frequencies that the Aironet 4000 Series Wireless LAN Adapter will usually still be successful in its transmission.

Data Transparency and Protocols

The Aironet 4000 Series Wireless LAN Adapter transports data packets transparently as they move through the wireless infrastructure. The PC Card operates similarly to a standard network product except the wire is replaced with a radio connection. No special wireless networking functions are required. All existing applications, which operate over a network, will operate using the Aironet 4000 Series


1-5


Protocols Supported

The Aironet 4000 Series Wireless LAN Adapter can be used in a variety of infrastructure configurations. Aironet

Access Points (AP4500 and AP4800) provide connections to Ethernet or Token Ring Networks. When using the Aironet standard device drivers, the PC Card is fully compliant with the following protocols and wired networks:

Radio Ranges

This section provides general guidelines on factors that influence network performance (see Section 4 - Site

Survey and Link Test ).

Site Survey

Because of differences in component configuration, placement and physical environment, every network application is a unique installation. Before installing the system, users should perform a site survey in order to determine the optimum utilization of networking components and to maximize range, coverage and network performance.

1-6


Here are some operating and environmental conditions that need to be considered:

• Data Rates. Sensitivity and range are inversely proportional to data bit rates. The maximum radio range is achieved at the lowest workable data rate. There will be a decrease in receiver threshold sensitivity as the radio data rate increases.

• Antenna Type and Placement. Proper antenna configuration is a critical factor in maximizing radio range. As a general guide, range increases in proportion to antenna height.

For a detailed explanation of antenna types and configurations along with guidelines on selecting antennas for specific environments, see the Aironet Antenna Guide, document number 710-003725.

• Physical Environments. Clear or open areas provide better radio range than closed or filled areas. Also, the less cluttered the work environment, the greater the range.

• Obstructions. A physical obstruction such as metal shelving or a steel pillar can hinder the performance of the PC Card, particularly when using the small Snap-

On antenna. Avoid locating the computing device and antenna in a location where there is a metal barrier between the sending and receiving antennas.

• Building Materials. Radio penetration is greatly influenced by the building material used in construction. For example, drywall construction allows greater range than concrete blocks. Metal or steel construction is a barrier to radio signals.

1-7


Link Test

The link test tool is used to determine RF coverage. The test results help the installer eliminate low RF signal level area that can result in loss of connection.

Radio Antenna

The Snap-On Diversity antenna comes standard with the

PC Card and provides omni-directional coverage.

A benefit of the diversity antenna system is improved coverage. At the edges of the RF coverage or fringe areas, there are very often multiple signals reaching the receiver, all from the same transmitter. These signals travel in different paths (multipath) and are caused by reflection and shadows of the RF signals. When the signals combine, the receiver may have trouble decoding the data. The Aironet radio’s ability to switch and sample between these antennas allows it to select the optimum antenna for receiving the packet.

Optional antennas are offered for the PC Card. Consult the

Aironet Antenna Guide document number 710-003725 for more information.

Security Features

The Aironet 4000 Series Wireless LAN Adapter employs

Direct Sequence Spread Spectrum Technology, previously developed for military “anti-jamming” and “low probability of intercept” radio systems.

The Aironet Access Point must be set to the same Service

Set 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 other.

1-8


Terminology

When configuring your system, and when reading this manual, keep in mind the following terminology:

Association – Each root unit or repeater in the infrastructure contains an association table that controls the routing of packets between the Access Point and the wireless infrastructure. The association table maintains entries for all the nodes situated below the Access Point on the infrastructure including repeaters and client nodes.

End Node – A client node that is located at the end of the

Network Tree.

Infrastructure – The wireless infrastructure is the communications system that combines Access Points, mobile nodes and fixed nodes. Access Points within the infrastructure can be either root units, which are physically wired to the LAN backbone, or can act as wireless repeaters. Other RF enabled devices serve as fixed nodes or mobile client nodes.

Parent/Child Node – Refers to the relationships between nodes in the wireless infrastructure. The complete set of relationships is sometimes described as a Network Tree.

For example, the Access Point (at the top of the tree) would be the parent of the end nodes. Conversely, the end nodes would be the children of the Access Point.

1-9


Power Saving Protocol (PSP) and Non-Power Saving

Protocol – The Power Saving Protocol allows computers

(usually portable computers) to power up only part of the time to conserve energy. If a client node is using the Power

Saving Protocol to communicate with the network, the

Aironet Access Point must be aware of this mode and implement additional features such as message store and forward. If the client node is powered from an AC line, PSP should not be used.

Repeater – A repeater is an Access Point that extends the radio range of the infrastructure. A repeater is not physically attached to the wired LAN, but communicates via radio to another Access Point, which is either a root unit or another repeater.

Root Unit – The root unit is an Access Point that is located at the top, or starting point, of a wireless infrastructure. A root unit provides the physical connection to the wired LAN

(such as Ethernet or Token Ring) and contains configuration information in its association table that covers all nodes that access the wired network (backbone). All Access Points directly attached to the wired LAN backbone are root units.

1-10


System Configurations

The Aironet 4000 Series Wireless LAN Adapter can be used in a variety of network system configurations. Aironet

Access Points (AP4500 or AP4800) provide connections to your Ethernet or Token Ring networks or act as repeaters increasing wireless communication range. The maximum communication range is based on how you configure your wireless infrastructure.

Examples of some common system configurations are shown on the pages that follow, along with a description of each.

Figure 1.1 - Ad Hoc Wireless LAN

An ad hoc wireless LAN is the simplest wireless LAN configuration. In a wireless LAN, using an ad hoc network operating system (such as Windows for Workgroups or

Windows 95), all devices equipped with the PC Card can be linked together and communicate directly with each other.

1-11


Figure 1.2 - Wireless Infrastructure

Access Point

(Root Unit)

Workstation Workstation

In a wireless infrastructure, an Aironet Access Point is used as a stand-alone root unit. The root unit is not attached to any wired LAN (such as an Ethernet or Token Ring LAN), but functions as a hub linking all stations together. This configuration is similar to the ad hoc network, except the

Aironet Access Point serves as the focal point for communications. This increases the effective communication range over the ad hoc LAN since both stations are not required to be in direct communication range of each other.

A Micro-Cellular Network can be created by placing two or more Aironet Access Points on a LAN.

The Aironet roaming protocols allow remote workstations to move from one microcell domain to another. The process is seamless and transparent. The connection to the file server or host is maintained without disruption. This configuration is useful with portable or mobile stations allowing them to be directly connected to the wired network, even while moving about (roaming). When an infrastructure is configured using multiple Aironet Access Points and/or repeaters, a mobile station is automatically associated and re-associated to the Aironet Access Point which provides the best performance. This is referred to as seamless roaming.

An Aironet Access Point can be configured as a standalone repeater to extend the range of your infrastructure, or to overcome an RF blocking obstacle. The repeater forwards traffic between the Aironet 4000 Series Wireless LAN

Adapter equipped workstations and devices and the wired

LAN by sending packets to either another repeater or to another Aironet Access Point attached to the wired LAN.

The data is sent through whichever route provides the greatest performance for the client. Multiple repeater hops can be supported in the path to the wired LAN.

1-14


Coverage Options

The system architecture options of the wireless station and

Access Points provide for a variety of coverage alternatives and flexibility. The system can be designed to provide a wide coverage area with minimal overlap (Figure 1.5) or coverage with heavy overlap (Figure 1.6). The latter improves system performance and protection against downtime in the event of a component failure.

Figure 1.5 - Minimal Overlap Coverage Option

Wired LAN

By arranging the Access Points so the overlap in coverage area is minimized, a large area can be covered with minimal system cost. The total bandwidth available to each mobile station will depend on the amount of data each mobile station desires to transfer and the number of stations located in each cell. Seamless roaming is supported as a mobile station moves in and out of range of each Access Point, thereby maintaining a constant connection to the wired

LAN. Each Access Point (and PC Card) must be configured with the same Service Set Identifier (SSID) in order to provide the roaming capability.

1-15


Figure 1.6 - Heavy Overlap Coverage Option

Wired LAN

By arranging the Access Points so the overlap in coverage area is nearly maximized, a large number of mobile stations can be supported in the same wireless infrastructure. However, units in overlapping coverage areas on the same frequency will detect adjacent cell traffic and delay transmissions that would cause collisions. This reduces the aggregate radio system throughput. Heavy cell overlap is not recommended for maximum system throughput. Due to the redundancy in coverage overlap, system access is not lost in the event of an Access Point failure. Upon failure of the Access Point, the station will automatically roam to an operational Access Point. With this architecture, all Access

Points and PC Card units must be configured with the same

Service Set Identifier (SSID).

1-16


Figure 1.7 - Multiple Overlapping Systems Coverage

Option

Wired LAN 2

Wired LAN 1

Multiple systems can operate in the same vicinity. The architecture provides multiple channels, which can exist in the same area with virtually no interference to each other. In this mode, each system must be configured with different

Service Set Identifiers (SSID) and different channels, which prevent clients from roaming to Access Points of a different wireless system.

Antenna Connectors

The PC Card has two female MicroMate antenna connectors on one end. All antennas and cables attached to the

PC Card must be equipped with male MicroMate connectors.

The two antenna connectors allow a Diversity Antenna or two separate antennas to be attached to the Aironet 4000

Series Wireless LAN Adapter. When two antennas are connected, the PC Card will automatically select antennas in order to provide the strongest signal for radio operations.

This feature improves packet delivery and system throughput by avoiding reception and transmission instances which are hampered by RF multipath signals or blocking structures in the environment.

2-3


Standard Antennas

The Snap-On Diversity antenna comes with the PC4500 and PC4800 and attaches directly to the PC Card. Its small size allows mobile communication in a small area (ad hoc network) where a larger antenna would be awkward or interfere with the use of the PC or terminal.

The design of the Snap-On and Remote Diversity antennas take full advantage of the PC Card’s ability to detect and use the strongest signal.

The Aironet 4000 Series Wireless LAN Adapter can also be used with a variety of optional external antennas. Consult the Aironet Antenna Guide (document number 710-003725) for antenna descriptions and configuration information.

NOTE: Only use antennas and cables supplied by

Aironet Wireless Communications.

Section 4

Utilities

This section describes procedures for using utilities and updating firmware depending on the operating system used.

See Appendix B for detailed configuration procedures for

WinDGS using Windows 95 or Windows 98.

Here’s what you will find in this section:

• Using the utilities

• Loading new firmware versions

Site Survey and Link Test

In order to perform a meaningful site survey, it is necessary to conduct a test that will accurately model the intended use of the system. It is important to perform a site survey using equipment which is similar to that implemented. Items to be surveyed are:

• Transmit power

• Antenna(s) type(s)

• Antenna(s) location(s)

• Packet (fragment) size

• Interference

The site survey should be conducted with all variables set to the operational values. It should also be performed during the time the RF link will generally be functioning with all other systems and noise sources operational. For efficiency, the site survey application should be executed entirely from the mobile station.

4-1

Utilities

The link test tool helps determine the RF network coverage.

The results of the link test will help eliminate low RF signal level areas that can result in loss of connection between the

PC Card and the Aironet Access Point.

It is important to remember the information being displayed is from the Aironet Access Point viewpoint. Therefore, packets sent are from the Aironet Access Point to the PC

Card client. Packets received are from the PC Card to the

Aironet Access Point. Signal quality is an estimate of the signal strength recorded at the time of packet reception by the radio.

Using Windows 3.11 or DOS to Perform a Link Test

Using Telnet

Link test using telnet is a useful tool for determining:

• Coverage range of an Access Point

• Communication range of stations/mobile stations

To perform the link test using a telnet session:

1.

Install the drivers.

2.

Configure the drivers for network operation.

3.

Ensure unique IP assignments of mobile/portable

PC Card devices and Aironet Access Point.

4.

Set up an Aironet Access Point for the intended operation (set fragmentation thresholds, RTS thresholds, etc.)

5.

Start the operating system on the mobile station.

6.

Configure the adapter.

7.

Make sure the mobile station is associated to the

Aironet Access Point.

4-2

Utilities

8.

Start a telnet session on the mobile station to the

Aironet Access Point. Depending on the system in use, the telnet application may have logging and note taking capability. If so, enable these modes.

9.

Navigate through the Aironet Access Point menu to the link test option. See the appropriate Access

Point Technical Reference Manual for more information.

10. Set up the test options to accurately model the system.

11. Set the test for continuous operation with a

1 second delay.

12. Begin traversing the area around the Aironet

Access Point to determine its coverage. If logging and notes are not possible with the telnet application, maintain a manual log.

The telnet session packets are interspersed with test packets which may have the effect of increasing the round trip time for some frames. The link test will show progress changes as the test is being conducted.

The first time delivery success rate for the packet may not be important for transaction based systems and can result in a slightly larger range. Using longer packets can provide some degree of safety margin in the range estimate.

NOTE: Roundtrip time will be effected by the telnet session maintenance.

4-3

Utilities

Using Windows 95 or Windows 98 to Perform a Link Test

You may use either:

• Telnet

• The link test or site survey commands in WinDGS

• Linkscope

4-4

Utilities

Link Test Command in WinDGS

WinDGS may be used to assess the performance of RF links. TCP/IP protocol must be installed to run this link test.

See the Help section of Windows 95/98/NT for more information on installing and setting up TCP/IP. An IP address must also be configured for the Access Point.

1.

From the link test command menu, enter the following parameters:

• IP address of Aironet Access Point:

This parameter specifies the IP address of the

Access Point with which you want to test the RF link.

Set this value before running the link test.

• Number of Packets:

This parameter specifies the number of packets the link test will attempt to send. The display will show the number of packets of the specified size that are successfully transmitted and received. This parameter is ignored if Continuous Link Test is selected.

• Packet Size:

This parameter specifies the size of the data packet to be sent to the Aironet Access Point. Be aware that the TCP/IP stack that comes with Windows 95 will fragment packets greater than 512 bytes. Therefore, the number of packets transmitted will not match the number of packets received (even if none are lost) if the packet size is greater than 512 bytes.

• Continuous Link Test:

Selecting this item causes the link test to run continuously until Stop, OK, or Cancel is selected. The

Number of Packets parameter is ignored if Continuous Link Test is selected.

4-5

Utilities

2.

Once the parameters have been entered, click on the Start button at the bottom of the dialog box to start the link test. When the link test is running, necessary statistics will be displayed and updated periodically.

3.

To stop the link test, click on Stop, OK, or Cancel at the bottom of the dialog box. Once the link test has sent the number of packets specified, the Stop button will toggle back to a Start button.

Site Survey

Site Survey provides information for signal strength, signal quality, and overall link quality as well as displaying all associated Access Points.

Packets are sent to each associated Access Point and echoed back. The signal strength associated to each node is displayed. This screen is updated every 10 seconds.

Linkscope

Linkscope provides a graphical display of:

• Signal Quality

• Signal Strength

Linkscope determines the performance of the RF link between a PC Card and an Aironet Access Point. Any

Windows 95, Windows 98, or Windows NT unit associated to an Aironet Access Point can run the linkscope test.

4-6

Utilities

Signal strength is displayed along the vertical axis of the graphical display. Signal quality is displayed along the horizontal axis. The combined result is represented by a diagonal line. The Aironet Access Point associating with the PC Card is indicated along the bottom of the display as well as its MAC address. For more information on the Aironet Access Point testing procedures, see the appropriate Access Point Technical Reference

Manual.

Edit Parameters

System Parameters

System parameters include:

• Name

• SSID

• Network Type (Infrastructure or Ad Hoc)

• Constant Awake Mode (CAM)

• Power Save Mode

• Fast Power Save Mode

• Maximum Power Save Mode

Name

The station name is displayed in the table of connected devices on the Access Point. It provides a logical name to determine which machines are connected without having to memorize every MAC address. The name can be up to 16 characters.

SSID

The Service Set Identifier (SSID) controls access to a given wireless network. This value MUST match the

SSID of any/all Access Points that you want to communicate with. If the value does not match, access to the system is not granted. The SSID can be up to 32 characters (case sensitive).

Network type (Infrastructure Mode)

This mode is used to set up a connection to a wired network, such as Ethernet or Token Ring. This mode requires an Access Point to gain access to the wired network.

B-6

Edit Parameters

Network type (Ad Hoc Mode)

This mode is used to set up a small, temporary network between two or more computers. For example, you might set up an ad hoc network between computers in a conference room so users can share information in a meeting.

Constant Awake Mode (CAM)

Constant Awake Mode is the normal mode for desktop machines or other machines where power consumption is not an issue. It keeps the radio powered up continuously so there is little latency for responding to messages. This mode is recommended for devices where high availability is desired.

Power Save Mode

Power Save Mode is recommended for devices where power consumption is a major concern, such as small battery powered devices. If the client node is powered from an AC line, PSP should not be used. Power Save

Mode causes the Access Point to buffer incoming messages. The Aironet 4000 Series Wireless LAN Adapter must wake up periodically and poll the Access Point to see if there are any buffered messages waiting. The PC

Card can request each message and then go back to sleep.

Fast Power Save Mode

Fast Power Save Mode (Fast PSP Mode) switches between PSP and CAM based on network traffic. When retrieving a high number of packets, Fast PSP Mode will switch to CAM to retrieve the packets. Once the packets are retrieved, it switches back to PSP.

B-7

Edit Parameters

Maximum Power Save Mode

Maximum Power Save Mode (Max PSP Mode) can only be used in conjunction with PS or Fast PSP Modes.This mode allows the Aironet 4000 Series Wireless LAN

Adapter to conserve the most power while still maintaining an infrastructure connection. Using Max PSP

Mode conserves power but will reduce throughput.

B-8

Edit Parameters

Network Parameters

User modifiable parameters are limited to the choice of

MAC Address:

• Factory MAC Address: This is the default MAC address which is guaranteed to be unique. Unless you have a very good reason to define your own MAC address, it is STRONGLY RECOMMENDED that you use the factory MAC address.

• User Defined MAC Address: If you must define your own MAC address, you can enter it here. If you do not use a unique value, you may not be able to communicate to your wired network or you may disrupt other network devices. For this reason, it is STRONGLY

RECOMMENDED that you use the factory MAC address. The MAC address is 12 hexadecimal digits.

You do not need to use delimiters, but you can use spaces or the colon character.

RF Network Parameters

RF Network Parameters include:

• Fragment Threshold: This parameter defines a threshold above which the RF packet will be split up or fragmented. If a packet is fragmented or transmission of part of it is interfered with, only the portion that was unsuccessful would need to be re-sent. The throughput will generally be lower for fragmented packets since the fixed packet overhead consumes a higher portion of the

RF bandwidth.

B-9

Edit Parameters

• Data Retries: This parameter defines the number of times a packet will be re-sent if the initial transmission is unsuccessful. If the network protocol automatically retries itself, set this to a small value. A “bad” packet status will be sent up the protocol stack more quickly so the application can re-transmit the packet.

• Basic Data Rate: This parameter determines the data rate used to transfer all management frames by the client device when associated within a given Basic Service Set (BSS). When operating in Infrastructure Mode, this parameter should be set to correspond to the

Access Point setting. When operating in Ad Hoc Mode, all stations should have the same setting.

Model Allowable Selections

B-10

Edit Parameters

Advanced (Infrastructure)

The following parameters are contained in both the Infrastructure and Ad Hoc Modes:

• Antenna Mode

• Specified Access Point

• RTS Threshold

• RTS Retry Limit

Antenna Mode

Three options are available for the type of antenna you have connected to the Aironet 4000 Series Wireless

LAN Adapter:

• Antenna Diversity: This allows the PC Card to use the stronger signal from the two antenna ports.

Diversity can help the radio maintain the RF connection in areas of interference. Due to the nature of how RF signals are affected by the surroundings, one antenna may be in an RF “null” where the signal is very weak, but the other antenna (even though it is only a small distance away) may have a stronger signal strength. The PC

Card would automatically select the antenna that has the highest signal strength. Antenna Diversity is the recommended setting for the standard

Snap-On antenna.

• Right Antenna Only (J1): Choose this option if the antenna you are using is connected to the right hand antenna port and you are not using the standard Snap-On antenna. The PC Card will not attempt to communicate using the left hand antenna port since no antenna is connected to it.

B-11

Edit Parameters

• Left Antenna Only (J2): Choose this option if the antenna you are using is connected to the left hand antenna port and you are not using the standard

Snap-On antenna. This tells the PC Card not to attempt to communicate using the right hand antenna port since no antenna is connected to it.

Specified Access Point

This parameter is the MAC address of the preferred

Access Point you want to associate with. It is important to note that if you specify the Access Point, you MAY associate to another Access Point if the Specified

Access Point is not found. If you roam out of range, you will probably associate with another Access Point.

Setting a Specified Access Point will slow down the roaming process. Thus, for normal operation for the majority of users, leave this field blank.

RTS Threshold

This parameter controls what size data packet the low level RF protocol issues to an RTS packet. There are several trade-offs to consider when setting this parameter. Setting this parameter to a small value causes RTS packets to be sent more often, consuming more of the available bandwidth, therefore reducing the apparent throughput of other network packets. However, the more often RTS packets are sent, the quicker the system can recover from interference or collisions.

Refer to the IEEE 802.11 Standard for more information on the RTS/CTS mechanism.

B-12

Edit Parameters

RTS Retry Limit

This parameter controls the number of times the PC

Card will re-send the RTS packet if it does not receive a

CTS from the previously sent RTS packet. Setting this to a large value will decrease the available bandwidth whenever interference is encountered, but will make the system more immune to interference and collisions.

Refer to the IEEE 802.11 Standard for more information on the RTS/CTS mechanism.

Advanced (Ad Hoc/IBSS)

In Ad Hoc Mode, you can also modify the following parameters:

• Channel

• Beacon Period

• Wake Duration

Channel

This parameter specifies the channel identifier the unit will use if it must start its own network. For all other situations, the radio will scan for the proper frequency. See

Appendix C for channel identifier parameters.

B-13

Edit Parameters

Beacon Period

This parameter specifies the duration between beacon packets that are used by IEEE 802.11 systems to synchronize the “hops” (change to another frequency).

The beacon packet contains timing information and hop pattern information that is broadcast over the airwaves.

Any station that can hear the beacon packet can then synchronize their internal timer so that it can hop at the correct time. The default beacon period is one-half of the dwell period so two beacons are transmitted per hop dwell period (default is 100 K

µ sec). Refer to the

IEEE 802.11 Standard for more information on the timing and scanning mechanism.

Wake Duration

This parameter specifies the amount of time per Hop

Dwell Period that the adapter stays awake listening for data packets. This is only used in Power Save Mode.
