2.0 Introduction

The MWI-5000 System is designed to help in the testing and evaluation of the MeshLinx MWI-5000, a tri-channel IEEE 802.11 MAC/Base Band processor. The system is a complete operating three channel Access Point that can be configured as a three sector SDMA AP or a dual-band (2.4 and 5GHz) AP with a monitoring channel. MWI-5000 System Features

The MWI-5000 System can operate three concurrent channels of IEEE 802.11b, g or a (or any combination) using the three sector SDMA antenna provided. Alternately, omni-directional antennas can be used for a dual-band AP with continuous monitoring. In either mode, the MWI-5000 Listen+Learn protocol simplifies the installation and management of one or more MWI-5000 System access points by automatically configuring the channel and transmit power settings for the AP. When enabled, the MWI-5000 Listen+Learn protocol monitors RF activity in the environment when the access point is powered on. This monitoring process discovers other access points (both MWI-5000 and non-MWI-5000 access points) in the vicinity of the MWI-5000 System. The data gathered during the monitoring process is then used to select channel and transmit-power settings that minimize interference between the MWI-5000 System and other access points, resulting in increased performance of wireless data transfer through the MWI-5000 System. When multiple MWI-5000 Systems are connected to the same wired network, the MWI-5000 Systems work cooperatively to determine the channel and transmit-power settings that provide optimal wireless data transfer performance for the wireless network.

3.0 Installation

This section contains information about proper installation of the system to maximize performance. Following these guidelines will enable the best possible results for the evaluation.

3.1 Finding the Correct Site

One of the major advantages of the MWI-5000 System is that it greatly simplifies the site selection process. However, there are some guidelines that should be followed to optimize performance.

3.1.1 SDMA Capacity vs. Range Mode

Although the simultaneous use of three channels is the main benefit of the sectorized antenna SDMA, it is also possible to increase range by setting all three sectors on the same channel. For maximum capacity the three sectors must be set to channel 1, channel 6 and channel 11.

3.1.2 User Distribution

As a general rule, it is a good idea to locate the MWI-5000 System in the center of the distribution of users, but this assumes a fairly even distribution.

Because configuration (and reconfiguration) of the sectors is so simple, and MeshLinx’s Listen+Learn software can help with interference mitigation and load balancing, this consideration for site selection is not very critical.

3.1.3 Avoiding Reflective Surfaces

The most important concern in the selection of a mounting site is the avoidance of walls, ceilings, floors and metal surfaces close to the MWI-5000 System. These surfaces tend to reflect radio frequency (RF) signals and, if they are close, reflect strong signals. This results in a reduction of SDMA effectiveness, which means more interference and therefore poorer signal quality.

Wherever possible, keep the MWI-5000 System 10-20 feet from walls. Ideally, it should be placed at a height that is equidistant from the ceiling and the floor (tabletop mount). It will work well where these goals can’t be met, but where they can, performance will be better.

3.1.4 Minimizing Interference

The MeshLinx Listen+Learn software enables the MWI-5000 System to operate efficiently even in the presence of interfering signals, but when looking for the ideal site, you should avoid certain things, including:

MESHLINX CONFIDENTIAL 5

Page 6

MeshLinx MWI-5000 User Guide

• 802.11b, 802.11g and Bluetooth Access Points

• 2.4GHz cordless telephones

• 2.4GHz wireless cameras, area monitors, etc.

• Microwave ovens in regular use

3.1.5 Obstacles

RF signals at 2.4GHz do not easily pass through obstacles. Depending on the construction material used, walls between the MWI-5000 System and the intended station(s) attenuate the signal, thereby reducing the effective range. It is always best to avoid as many walls as possible, especially if the walls have significant metal content or foil-backed insulating materials.

Signals will traverse floors or ceilings, so it is possible to cover more than one floor with a single MWI-5000 System, but they do tend to be severe attenuators, and you should expect reduced range on the other side.

3.2 Power and Network Connections

The ideal location must also provide for power and network connections for the MWI-5000 System. Because it is 802.3af compliant, a single Power over Ethernet cable will provide both. If PoE hubs are not in use, the MWI-5000 System must be located where a source of AC power is available.

3.2.1 Serial Port

The serial port is RS-232C compliant. We recommend that this port be used for initial configuration and testing. Once the settings for the wired Ethernet port and the wireless interfaces are set to work with your network, any one of them (serial port, Ethernet port, or wireless) may be used for configuration changes or AP management. Be sure that the serial port settings of the attached terminal device are the same as those of the MWI-5000 System.

Table 3.1 Serial Port Settings

Item Setting Bit Rate Data Bits Stop Bits Parity Flow Control

115200bps 8 1 None None

3.2.2 Power-over-Ethernet Connection

When connected to an IEEE 802.3af compliant powered hub, the MWI-5000 System receives all of its required power from the hub. No external power supply is required. Once the PoE cable is plugged into the MWI-5000 System, the unit begins its initialization. This will take approximately one minute.

3.2.3 Using the External Power Supply

If you are not using powered Ethernet, the MWI-5000 System is powered by the included external power supply. Plug the external supply into an AC source (100– 250V, 50–60Hz) and plug the DC side into the MWI-5000 System External Power Supply connector. The unit will begin its initialization. This will take approximately one minute.

3.2.4 Changing the Factory Default MAC Address

The MWI-5000’s Ethernet MAC address is programmed at the factory and should not require user modification. If the user wishes to change the factory default MAC address to a user-specific MAC address, the serial interface must be used. After setting up the serial interface as specified in Serial Port above, follow the procedure given below to change the MAC address.

1. Power cycle the AP.

2. When it begins to boot, press <Ctrl><C> simultaneously (bootloader prompt

appears).

3. Execute the following command to set the MAC Address of the Ethernet port. set_npe_mac -p 0 xx:xx:xx:xx:xx:xx<Enter> (xx:xx:xx:xx:xx:xx is the MAC address)

4. Power cycle the AP. The new MAC address should take effect.

5. The wireless interface MAC addresses should also be updated.

4.2 Command Line Interface

This section explains the Command Line Interface (CLI) used with the MWI-5000 System.

Note: Although the CLI can be used to change settings while the MWI-5000

System is running, we recommend that it be stopped before making changes and restarted once the changes have been made. Changes do not take affect until the system is restarted. The system uses NICs that require significant processor power while running, which limits the time available to the CLI and causes it to miss occasional characters.

4.2.1 Command Conventions

The commands are shown using the following conventions:

• Triangular brackets (< >) indicate a required choice.

• Square brackets ([ ]) indicate optional items.

• Vertical bars ( | ) separate mutually exclusive choices.

• Boldface indicates commands and keywords that are entered exactly as shown.

• Italics indicate values that must be supplied by you.

Examples:

• Examples show screen displays and the command line in the screen font.

• Information you need to enter in examples are shown in boldface font.

• Variables that you must supply are shown in italic font.

Selecting a menu item (or screen) is indicated by the following convention:

• Click Start>Settings>Control Panel.

4.2.2 Getting Started

When the MWI-5000 System completes its initialization following power up, the terminal equipment attached to the serial port will display a login prompt. Type admin and press Enter, then enter m3shl1nx for the password and press Enter again. This will bring the prompt IXP425>. The system can now be configured, operated, and managed using the CLI.

4.2.3.21 Wireless Bridging/Backhaul

The MWI-5000 supports a flexible wireless bridging technology. The system supports up to 16 wireless bridge links on each WIF, and up to 48 total per transceiver card on the AP. Wireless bridging can be used to form mesh networks with other MeshLinx AP’s. This is accomplished by allocating multiple bridge endpoints on an AP with a desired SSID. These bridge endpoints automatically discover other endpoints with the same SSID, and establish bridges on-the-fly. Spanning Tree Protocol runs in order to prevent forwarding loops.

bridge add wif<1|2|3> <ssid> – Add a bridge to wif<1|2|3> with the specified SSID. By default mode is set to manual.

bridge del wif<1|2|3> <ssid> - Delete the specified bridge endpoint SSID from the specified WIF. This will disconnect any connected bridge endpoints using this SSID.

MESHLINX CONFIDENTIAL 2

Page 26

MeshLinx MWI-5000 User Guide

bridge wif<1|2|3> <ssid> ssid <new-ssid> - Change the SSID of a particular bridge.

bridge wif<1|2|3> dot1q [enabled | disabled] – enable/disable

802.1Q VLAN tagging on the wireless bridge. bridge wif<1|2|3> <ssid> security <enabled|disabled> – Enable the

use of AES CCMP encryption on the wireless bridge. This utilizes the pre-shared key specified in the passphrase command.

bridge wif<1|2|3> <ssid> mode <auto <num> |manual> - Sets the mode of the bridge SSID. If set to manual, then only 1 bridge endpoint is allocated/configured on the WIF. If set to auto, multiple bridge endpoints (up to 16) are allocated on the WIF, and allows the AP to form as many wireless bridges as needed.

bridge list - Displays the currently configured wireless bridges.

Example:

To setup a wireless bridge mesh network, configure a number of MeshLinx AP’s in the following way. In this example, the network can have up to 5 AP’s, however a user could select up to 16.

set wif3 channel 64 bridge wif3 add bridge-test bridge wif3 bridge-test security enable bridge wif3 bridge-test passphrase secret bridge wif3 dot1q disable

bridge wif3 mode auto 4 # Could be as big as 16

Use the following commands to check the wireless bridge status:

bridge list cat /proc/management/bridge

4.2.3.22 Bridge Spanning Tree Protocol (STP) Configuration (switch)

set switch stp <enable|disable|auto> - Controls the enabling/disabling of STP on the AP. “auto” will only turn STP on when necessary, i.e. when more than one bridge port is enabled on the access point.

set switch priority <0-65535> - Sets the bridge priority used by STP. The industry standard value is 32768 (0x8000). The default used by the MeshLinx access point is 0x8010, in order to provide out-of-box compatibility with existing network infrastructures.

4.2.4 Redboot and Firmware Update

The MWI-5000 System includes a utility to manage the firmware update process, which uses the Trivial File Transport Protocol (TFTP) to upload the revised firmware. The following describes the procedure for performing the update.

A TFTP server is required to accomplish these updates. The flash update uses a TFTP client on the AP to download the new firmware image from a TFTP server on the network.

4.2.4.1 Updating Redboot

Set up a TFTP server on either a Linux or Windows system and connect it to the network.

With the MWI-5000 booted to normal mode enter use TFTP to copy the new Redboot image to the unit. It is recommended that the /tmp directory be used:

tftp –r <redboot file> -l <redboot file> hostaddr Ex: tftp –r X890-ixp425-le-gnu_redboots.bin –l X890-ixp425-

le-gnu_redboots.bin 192.168.1.1

Once the file has been transferred, use the dd command to load it into the flash:

dd if=/tmp/<redboot file> of=/dev/mtdblock0

The output of this command should show:

651+1 records in 651+1 records out

It is important that the records in and out match with 651+1 being the output. If the numbers do not match then Do Not Reboot the unit. Ensure the Redboot filename is correct (not compressed with gzip or some other issue) and retry the dd command. If necessary repeat the TFTP sequence to re-copy the file to the unit.

Once the process is completed successfully, the unit can be rebooted.

4.2.4.2 Update from the Command Line

Setup a TFTP server on either a Linux or Windows system and connect it to the network.

Copy three image files (XXX_ixp425-le-gnu_waps.jffs2, XXX_ixp425-legnu_rootfs.jffs2, and XXX_ixp425-le-gnu_kernel.bin, where XXX is the build number) to the TFTP server directory (/tftpboot on Linux).

Start the AP and configure its IP address so it can reach the TFTP server.

Type flash at the AP command line prompt ( IXP425> ).

MESHLINX CONFIDENTIAL 3

Type y when asked to confirm the flash update. Enter the TFTP server’s IP address followed by enter when asked. Enter XXX (where XXX is the build number) followed by enter when asked for the

version number. Programming Firmware. This will take about 1 minutes. Please wait will be

displayed. Wait for it to finish. If the update failed, an error message will be display. Please check the TFTP

server’s IP address, build number, and network connection before trying it again. If the update is successful, please power the MWI-5000 System off and then on.

The next boot will use the newly installed image.

4.2.4.3 Update from the Web Interface

Setup a TFTP server on either a Linux or Windows system and connect it to the network.

Start the AP and configure its IP address so it can reach the TFTP server. Launch the web browser Connect to the AP by typing in the IP address of the AP in the browser Log into the Ap via web interface when prompted. (NOTE: password is case-

4.2.4.4 Update from via RedBoot

If the previous flash image is damaged, it may be necessary to revert to the last known-good flash image via RedBoot.

Setup a TFTP server on either a Linux or Windows system and connect it to the network.

Reboot the AP and press Control-C immediately to get in the RedBoot screen

wireless interface. The IP address of the client device (Ethernet NIC or wireless NIC) should be set to an address in the same subnet as the MWI-5000 System, (e.g., if the MWI-5000 System is set to IP address 192.168.1.1, the NIC should be set to 192.168.1.x, where x is a number between 2 and 255, so that the full IP address does not conflict with another device in the subnet).

Open a Web browser and enter the address of the MWI-5000 System (e.g., http://192.168.1.1). A login and password are required to access the system, as shown in Figure 4.. The defaults are login: admin and password: m3shl1nx. (passwords are case-sensitive) This connects to the MWI-5000 System Web interface, and the main screen displays, as shown in Figure 4.3

7.0 Configurable Parameters

This section provides details of the configurable parameters that are accessible through either the CLI or HTTP user interfaces. It focuses on the effects of the parameters and why one would want to change them.

Each configurable parameter has an associated API function that provides access to modify it. Both the CLI and HTTP methods of changing a particular parameter access the same API function. The user interfaces are different (see preceding sections on CLI and HTTP) but the underlying mechanisms are t h e same.

7.1 Wireless Sectors (interfaces)

The term sector in the MWI-5000 product represents a wireless interface consisting of radio, base-band and MAC components. Wireless sector and wireless interface are used interchangeably to describe the same thing.

The MWI-5000 production product has three or more wireless interfaces, each of which can function as a physical AP.

Each of the three interfaces has a number of configurable parameters that can impact operation of the radio, base-band or MAC components. The use of each parameter is discussed below. See the CLI or HTTP sections for information on setting parameters.

7.1.1 MAC Address

The MAC address for each wireless interface can be changed to suit the needs of a particular user and/or site. Although the MWI-5000 factory default configuration provides unique MAC addresses for the Ethernet interface and all wireless interfaces, the user may override these with lo cally-administered MAC addresses or with MAC addresses prefixed with a user-specific OUI.

There is no need for a user to change the MAC address. It is entirely optional.

MESHLINX CONFIDENTIAL 8

Page 84

MeshLinx MWI-5000 User Guide

7.1.2 Mode

Each wireless interface may be set to operate in one of four 802.11 modes, 11A, 11B, 11BG and 11G. Switching modes may have side-effects that must be anticipated. For example, switching from 11A to 11B causes the selection of a new default channel appropriate to that mode. More on this under each mode discussed below.11A Mode

11A mode selects the 5 GHz band (channels 36, 40, 44, 48 etc). The 5 GHz band has the advantages of less interference than the 2.4 GHz band, more channels to choose from and data rates up to 54 Mbps. Setting the mode of a wireless interface to 11A restricts associations on that interface to stations operating in 11A mode.

One disadvantage of 11A mode is the regulatory domain specific restrictions on operating in the presence of radar signaling. In the US, Europe and Australia, it is a requirement to immediately vacate certain channels where known radar signatures are detected. The sets of channels to be concerned about are 52 – 64 (US and Europe) and 100 – 140 (Australia, parts of Europe and soon to be US).

The MWI-5000 will automatically monitor for known radar signatures when Spectrum Management is enabled (see discussion of this parameter below). If radar signatures are detected, the MWI-5000 will switch to a radar-free channel. The process of switching channels may disrupt the quality of time-sensitive services like voice. Since radar avoidance is required by law (see the 802.11h standard and associated FCC and ETSI documents), this potential disruption is unavoidable when operating in affected channels.

7.1.2.1 11B Mode

11B mode selects the 2.4 GHz band (channels 1 through 11). The 2.4 GHz band is considerably more congested than the 5 GHz band and is limited to data rates up to 11 Mbps. Setting the mode of a wireless interface to 11B restricts associations on that interface to stations operating in 11B mode.

Select 11B mode when the BSS needs to support only 11B stations and not 11G stations.

7.1.2.2 11BG Mode

11BG mode selects the 2.4 GHz band (channels 1 through 11) in “mixed” mode. The 2.4 GHz band is considerably more congested than the 5 GHz band and is limited to data rates up to 11 Mbps for 11B stations and 54 Mbps for 11G stations.

Note that the overall throughput for a station operating in mixed mode may be significantly lower, due to 11G protection mode (self-CTS). 11G protection mode adds some overhead to 11G transmissions to prevent them from impacting legacy 11B traffic. The MWI-5000 (and participating 11G stations) automatically engage this mode when

required. The result of engaging protection mode is that the performance of 11G stations is substantially reduced. See the discussion of self-CTS for more information.

Select 11BG mode when the BSS needs to support both 11B and 11G stations.

7.1.2.3 11G Mode

11G mode selects the 2.4 GHz band (channels 1 through 11) in “pure G” mode. The 2.4 GHz band is considerably more congested than the 5 GHz band and is limited to data rates up to 54 Mbps.

Note that “pure G” mode assumes there are no 11B stations operating in the BSS and that protection mode (self-CTS) is not required. This allows the interface to operate at optimal efficiency, achieving throughput similar to 11A mode in the 5 GHz band. This of course will depend on local interference in the selected channel.

Select 11G when the BSS needs to support only 11G stations and not 11B stations.

7.1.3 Channel

Selection of a particular mode results in selection of a default channel for that mode. Depending on interference and congestion in that default channel, it may or may not yield optimal performance. Manually selecting a new channel is experimental at best. You can simply try another channel and see if your throughput improves. Avoiding channel 6 in the 2.4 GHz band is a good idea, since many access points default to that channel and it tends to be congested.

If the Listen + Learn feature is enabled, the process of channel selection is continuous and fully automatic. The MWI-5000 monitors for interference in all channels and either stays on the current channel or switches channels if overall performance would benefit from the switch. Needless to say, enabling Listen + Learn is recommended over manual channel selection.

7.1.4 Self-CTS (11G Protection Mode)

11G Protection Mode is automatically enabled whenever both 11G and 11B stations interoperate within a BSS. The 802.11g standard requires that this be fully automatic.

Turning 11G Protection Mode off is an option for 11G (“pure G”) mode if the user wishes to completely eliminate the possibility that use of self-CTS is adversely affecting 11G throughput (for benchmarking, etc).

There is no need for a user to change this parameter. It is entirely optional and probably better avoided.

7.1.5 Transmit Power

The Transmit Power setting determines the power level in dBm that frames will be transmitted at. The Transmit Power level must be carefully balanced with the Maximum Data Rate to avoid distortion. For example, setting the Transmit Power to 25 dBm with the Maximum Data Rate at 54 Mbps will likely result is distortion and therefore failed attempts to transmit. Lowering either the Transmit Power or the Maximum Data Rate will eliminate the distortion, thus a Transmit Power of 25 dBm will work much better with a Maximum Data Rate of 48 Mbps or 36 Mbps.

If the user wishes to elevate the Transmit Power in order to reach a distant station, it is likely that the Maximum Data Rate will need to be lowered to avoid distortion.

Normally, this parameter should not be adjusted by the user as it is overridden by the default Automatic Transmit Power Adjustment setting. See the section on Automatic Transmit Power Adjustment for more information.

7.1.6 Automatic Transmit Power Adjustment

The Automatic Transmit Power Adjustment parameter determines behavior of the MWI5000 device driver with respect to transmit power limitation. It defaults to a setting of Max54, which ensures that the device driver will never transmit a frame with a transmit power level too high for the data rate. This setting overrides the Transmit Power value in dBm.

It is recommended that this parameter be set to Max54 and not modified by the user, as doing so guarantees the MWI-5000 will never transmit a distorted frame due to an excessive transmit power level (optimizes range and throughput together).

If the Listen + Learn feature is enabled, the process of transmit power adjustment is continuous and fully automatic. The MWI-5000 monitors all channels and adjusts its transmit power to accommodate nearby MWI-5000 access points. Needless to say, enabling Listen + Learn is recommended over manual Transmit Power selection.

7.1.7 Digital Pre-distortion

Digital Pre-distortion is a MeshLinx-proprietar y feature that improves transmit efficiency when used with certain radios. For the Maxim radio in the MWI-5000 production hardware, this parameter has no effect. Future versions of the MWI-5000 hardware may use radios where this parameter does have effect and this document will be updated to advise its use.

7.1.8 Sensitivity

The receive sensitivity parameter determines how sensitive a wireless interface radio is to low-energy signals. A low-energy signal could be a distant station that is legitimately trying to associate with the MWI-5000 AP or it could be cross-interface interference from another wireless interface on the same MWI-5000 mini-PCI board.

The sensitivity parameter is set to “high” by default, to ensure that distant stations are “heard” by the MWI-5000. If it is known that all stations needing network access through the MWI-5000 are relatively close the receive sensitivity can be set to “medium” or “low”.

The only reason to set sensitivity to anything but “high” is to avoid cross-inter face interference between wireless interfaces on the same MWI-5000 mini-PCI board. This might occur if you are running two or three interfaces in the same mode (e.g. 11G) and on adjacent channels.

Sensitivity is an advanced tuning parameter that normally does not need to be changed from its default “high” setting. Avoid changing it unless you suspect cross-interface interference between two or more interfaces on your MWI-5000 board.

7.1.9 Maximum Data Rate

The maximum data rate parameter limits the data rate used on a MWI-5000 interface. It defaults to the maximum rate allowed for an operating mode (e.g. 54 Mbps for 11A and 11G, 11 Mbps for 11B). The maximum data rate is used in the MWI-5000 software’s auto-rate-adjusting algorithm and is the maximum rate that the software will adjust to when up-rating.

There is typically no need to modify the maximum data rate, except for a situation where high transmit power levels are required to reach distant stations. In this case, a data rate of 54 Mbps might not be achievable at a high power level like 20 dBm (due to distortion) and the maximum data rate should be set to something lower like 48 Mbps or 36 Mbps.

Note that the MWI-5000 software’s auto-rate-adjusting algorithm will work around a problem with high transmit power by retransmitting at a lower data rate when a higher data rate fails. Although this works, it is not as efficient as avoiding the failing data rate altogether. In cases where the transmit power needs to be set higher than normal to reach distant stations, it may be necessary and will be more efficient to reduce the maximum date rate to account for the potential distortion at the default maximum data rate.

See the discussion of transmit power for more information.

7.1.10 Diversity

Diversity controls the use of antennas on the MWI-5000. Each wireless interface has a primary antenna (Antenna 1, default) and a secondary antenna (Antenna 2). Either of these antennas can be selected manually for an interface. The setting applies to both receive and transmit operations.

Setting Diversity to Both causes the device driver to al ternately try each antenna, eventually settling on the antenna that yields the best performance.

For transmit (using Both), the preferred antenna setting is maintained on a per-station basis and attempts to transmit to a station are tried first using the preferred antenna from the last transmission.

For receive (using Both), the antenna setting is mostly driven by the transmit diversity algorithm (transmit diversity trumps receive diversity). When there is little transmit activity to drive diversity, the receive diversity algorithm selects an antenna that has the highest RSSI for all stations combined. Typically, it is not the case that traffic will be mostly receive traffic and most of the time, diversity will be driven by the transmit algorithm.

The need to modify this parameter is site-dependent. Some users may find that setting Diversity to Both yields better overall performance for all stations. Other users may find that best performance is achieved by selecting a particular antenna. The best way to establish this is to experiment with the three settings, measure the performance yield of each setting and make a decision based on those results.

7.1.11 Header (preamble)

The Header parameter determines the default preamble type that the MWI-5000 MAC will use to transmit in 11B mode. It has no meaning in OFDM modes (11G or 11A).

In 11B mode, a longer preamble allows the receiving side greater time to synch-up on the incoming frame (144 microseconds for long, 72 microseconds for short). The MWI-5000 will receive 11B frames that are transmitted by a station with either long or short preamble and will respond to (acknowledge) received frames using the same preamble length as the received frame. To summarize:

• The header parameter is specifi c to 11B mode

• It determines only how the MWI-5000 will transmit 11B frames

• It takes 72 microseconds longer to transmit a 11B frame with a long preamble

• Using long preamble may achieve greater interoperability with legacy 11B

7.1.12 Beacon Interval

The Beacon Interval is the period in milliseconds between beacon transmissions in a BSS. This parameter can be adjusted higher or lower as a user requires, however adjusting it to too high a value may cause stations to disassociate (station-dependent).

This is set to 100 milliseconds by default and the user should not need to modify it.

7.1.13 Fragmentation

The Fragmentation parameter determines whether or not the MWI-5000 MAC will fragment frames into smaller pieces, as indicated by the Fragmentation Threshold parameter. Typically, fragmentation is done to ensure that frames are transmitted cleanly on the first try, by reducing the number of continuous bits transmitted and thereby the likelihood of a transmission error.

Fragmentation overhead is significant, due to the acknowledgement required for every fragment (as opposed to a single acknowledgement for the complete frame). Typically, modern auto-rating algorithms obviate fragmentation . . . although there may be extreme cases where better throughput could be achieved using fragmentation. Users in this situation probably have a serious problem in their network that needs correcting first.

Normally, this parameter should not be modified by the user and should only be modified either as an experiment or by a wireless expert who has determined that fragmentation will solve a specific problem he’s experiencing.

7.1.14 RTS/CTS

The RTS/CTS parameter determines whether or not the MWI-5000 MAC will initiate an RTS/CTS sequence preceding transmission of certain data frames, as indicated by the RTS/CTS Threshold parameter. Typically, RTS/CTS exchanges are done to ensure the medium is clear prior to transmitting data. Often, this is done to avoid the so-called “hidden node problem”.

RTS/CTS overhead is significant, due to the RTS and CTS transmission times and the SIFS times between them.

Normally, this parameter should not be modified by the user and should only be modified either as an experiment or by a wireless expert who has determined that use of RTS/CTS will solve a specific problem he’s experiencing (such as the hidden node problem).Sector (interface) Operating Mode

This parameter should be left at the “Normal” setting, unless there is a specific need to use the interface for spectrum analysis. Note that setting this parameter to Basic Spectrum Analyzer disables all access point functionality previously running on that interface.

8.0 Glossary

802.11: 802.11 is a family of specifications for Wireless Local Area Networks (WLANs) developed by a working group of the Institute of Electrical and Electronics Engineers (IEEE). The original specification provides for an Ethernet Media Access Controller (MAC) and several physical layer (PHY) options, the most popular of which uses GFSK modulation at 2.4GHz, enabling data rates of 1 or 2Mbps. Since its inception, two major PHY enhancements have been adopted and become “industry standards”. 802.11b adds CCK modulation enabling data rates of up to 11Mbps, and 802.11a specifies OFDM modulation in frequency bands in the 5 to 6GHz range, and enables data rates up to 54Mbps.

AICS: Automatic Intelligent Channel Selection is the capability for the Access Point to select best channel based on the RF environment conditions.

ATPC: Automatic Transmit Power Control is the capability for the Access Point to select best transmit power based on the RF environment conditions.

Authentication: The process of establishing the identity of another unit (client, user, device) prior to exchanging sensitive information.

Bluetooth: An open specification for short-range wireless voice and data communication. Bluetooth is a trademark owned by Telefonaktibolaget L M Ericsson, Sweden, and licensed to promoters and adopters of the Bluetooth Special Interest Group (SIG).

DFS: Dynamic frequency selection refers to the radar avoidance algorithm referred by 802.11h amendment.

DHCP: Dynamic Host Configuration Protocol (DHCP) is a communications protocol that lets network administrators centrally manage and automate the assignment of Internet Protocol (IP) addresses in an organization's network. Using the Internet Protocol, each machine that can connect to the Internet needs a unique IP address. When an organization sets up its computer users with a connection to the Internet, an IP address must be assigned to each machine. Without DHCP, the IP address must be entered manually at each computer and, if the computer moves to another location in another part of the network, a new IP address must be entered. DHCP lets a network administrator supervise and distribute IP addresses from a central point and automatically sends a new IP address when a computer is plugged into a different place in the network.

DNS: Domain Name Service. An Internet service that translates a domain name such as example-systems.com to an IP address, in the form xx.xx.xx.xx, where xx is an 8 bit hex number.

EIRP: The Effective Isotropic Radiated Power of a t ransmitter is the power that the transmitter appears to have if the transmitter’s antenna was an isotropic radiator, i.e., if it radiated equally in all directions. By virtue of the gain of a radio antenna— omni-directional or directed—or a dish, a beam is formed that preferentially transmits the energy in one direction. The EIRP is determined from the product of the gain and the transmitter power.

Ethernet: Ethernet is the most widely installed local area network (LAN) technology. Specified in a standard, IEEE 802.3, Ethernet was originally developed by Xerox and then developed further by Xerox, DEC, and Intel. An Ethernet LAN typically uses coaxial cable or special grades of twisted-pair wires. Ethernet is also used in wireless LANs. The most commonly installed Ethernet systems are called 10-BaseT and provide transmission speeds up to 10Mbps. Devices are connected to the cable and compete for access using a Carrier Sense Multiple Access with Collision Detection (CSMA/CD) protocol.

Fast Ethernet or 100-BaseT provides transmission speeds up to 100Mbps and is typically used for LAN backbone systems, supporting workstations with 10-BaseT cards. Gigabit Ethernet provides an even higher level of backbone support at 1000Mbps (1 gigabit or 1 billion bits per second). 10Gbps Ethernet provides up to 10 gigabits per second.

HTTP: The Hypertext Transfer Protocol (HTTP) is a set of rules for exchanging files (text, graphic images, sound, video, and other multimedia files) on the World Wide Web. Relative to the TCP/IP suite of protocols (which are the basis for information exchange on the Internet), HTTP is an application protocol.

Hub: In data communications, a hub is a place of convergence where data arrives from one or more directions and is forwarded out in one or more other directions. A hub usually includes a switch of some kind. (And a product that is called a "switch" could usually be considered a hub as well.) The distinction seems to be that the hub is the place where data comes together and the switch is what determines how and where data is forwarded from the place where data comes together. Regarded in its switching aspects, a hub can also include a router.

IEEE: Institute of Electrical and Electronics Engineers. The IEEE describes itself as the world’s largest professional society. The IEEE fosters the development of standards that often become national and international standards, such as 802.11.

IP: The Internet Protocol (IP) is the method or protocol by which data is sent from one computer to another on the Internet. Each computer (known as a host) on the Internet has at least one IP address that uniquely identifies it from all other computers on the Internet. When you send or receive data (for example, an e-mail note or a Web page), the message gets divided into little chunks called packets. Each of these packets contains both the sender's Internet address and the receiver's address. Any packet is sent first to a gateway computer that understands a small part of the Internet. The gateway computer reads the destination address and forwards the packet to an adjacent gateway that in turn reads the destination address and so forth across the Internet until one gateway recognizes the packet as belonging to a computer within its immediate neighborhood or domain. That

MESHLINX CONFIDENTIAL 9

MeshLinx MWI-5000 User Guide

gateway then forwards the packet directly to the computer whose address is specified.

ISP: An ISP (Internet Service Provider) is an entity that provides individuals and companies access to the Internet and other related services such as Web site building and hosting. An ISP has the equipment and the telecommunication line access required to have a Point-of-Presence (PoP) on the Internet for the geographic area served.

LAN: A Local Area Network (LAN) is a group of computers and associated devices that share a common communications line and typically share the resources of a single processor or server within a small geographic area (for example, within an office building). Usually, the server has applications and data storage that are shared in common by multiple computer users. A local area network may serve as few as two or three users (for example, in a home network) or as many as thousands of users (for example, in an FDDI network).

MAC: Medium Access Control. In a WLAN network card, the MAC is the radio controller protocol. It corresponds to the ISO Network Model's level 2 Data Link layer. The IEEE 802.11 standard specifies the MAC protocol for medium sharing, packet formatting and addressing, and error detection.

OFDM: Orthogonal Frequency-Division Multiplexing (OFDM) is a method of digital modulation in which a signal is split into several narrowband channels at different frequencies. The technology was first conceived in the 1960s and 1970s during research into minimizing interference among channels near each other in frequency.

In some respects, OFDM is similar to conventional frequency-division multiplexing (FDM). The difference lies in the way in which the signals are modulated and demodulated. Priority is given to minimizing the interference, or crosstalk, among the channels and symbols comprising the data stream. Less importance is placed on perfecting individual channels.

RADIUS: Remote Authentication Dial-In User Service (RADIUS) is a client/server protocol and software that enables remote access servers to communicate with a central server to authenticate dial-i n (or other temporarily connected) users and authorize their access to the requested system or service. RADIUS allows a company to maintain user profiles in a central database that all remote servers can share. It provides better security, allowing a company to set up a policy that can be applied at a single administered network point. Having a central service also means that it's easier to track usage for billing and for keeping network statistics.

Router: On the Internet, a router is a device or, in some cases, software in a computer, that determines the next network point to which a packet should be forwarded toward its destination. The router is connected to at least two networks and decides which way to send each information packet based on its current understanding of the state of the networks it is connected to. A router is located at

any gateway (where one network meets another), including each Internet point-ofpresence. A router is often included as part of a network switch.

Routing is a function associated with the Network layer (layer 3) in the standard model of network programming, the Open Systems Interconnection (OSI) model. A layer-3 switch is a switch that can perform routing functions.

RRM: Radio Resource Measurement (RRM) refers to 802.11k amendment. SDMA: Spatial Division Multiple Access (SDMA) is a communications mode that

optimizes the use of the radio spectrum and minimizes the system cost by taking advantage of methods to segment geographic areas.

SIFS: Short Inter-Frame Space are found in IEEE 802.11 networks. Employed for the highest priority transmissions that enables stations with this type of

SNMP: Simple Network Management Protocol (SNMP) is the protocol governing network management and the monitoring of network devices and their functions. It is not necessarily limited to TCP/IP networks.

SNMP is described formally in the Internet Engineering Task Force (IETF) Request for Comment (RFC) 1157 and in a number of other related RFCs.

Switch: In telecommunications, a switch is a network device that selects a path or circuit for sending a unit of data to its next destination. A switch may also include the function of the router, a device or program that can determine the route and specifically what adjacent network point the data should be sent to. In general, a switch is a simpler and faster mechanism than a router, which requires knowledge about the network and how to determine the route.

Relative to the layered Open Systems Interconnection (OSI) communication model, a switch is usually associated with layer 2, the Data-Link layer. However, some newer switches also perform the routing functions of layer 3, the Network layer. Layer 3 switches are also sometimes called IP switches.

TCP: Transmission Control Protocol (TCP) is a set of rules (protocol) used along with the Internet Protocol (IP) to send data in the form of message units between computers over the Internet. While IP handles the actual delivery of the data, TCP keeps track of the individual units of data (called packets) that a message is divided into for efficient routing through the Internet.

TCP is a connection-oriented protocol, which means that a connection is established and maintained until such time as the message or messages to be exchanged by the application programs at each end have been exchanged. TCP is responsible for ensuring that a message is divided into the packets that IP manages and for reassembling the packets back into the complete message at the other end. In the Open Systems Interconnection (OSI) communication model, TCP is in layer 4, the Transport Layer.

TCP/IP: Transmission Control Protocol/Internet Protocol(TCP/IP) is the basic communication language or protocol of the Internet. It can also be used as a communications protocol in a private network (either an intranet or an extranet). When you are set up with direct access to the Internet, your computer is provided

MESHLINX CONFIDENTIAL 9

Page 94

MeshLinx MWI-5000 User Guide

with a copy of the TCP/IP program just as every other computer that you may send messages to or get information from also has a copy of TCP/IP.

TCP/IP is a two-layer program. The higher layer, Transmission Control Protocol, manages the assembling of a message or file into smaller packets that are transmitted over the Internet and received by a TCP layer that reassembles the packets into the original message. The lower layer, Internet Protocol, handles the address part of each packet so that it gets to the right destination.

Telnet: Telnet is the way to access someone else's computer, assuming they have given permission. (Such a computer is frequently called a host computer.) More technically, Telnet is a user command and an underlying TCP/IP protocol for accessing remote computers. On the Web, HTTP and FTP protocols allow you to request specific files from remote computers, but not to be actually logged on as a user of that computer.

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 Equivalent Privacy, which is used to secure 802.11 WLANs. TKIP provides per-packet key mixing, a message integrity check, and a re-keying mechanism, thus fixing the flaws of WEP.

WEP: Wired Equivalent Privacy is the built-in baseline security protocol that is rolled into the 802.11b protocol. WEP is disabled by default in most shipping WLAN hardware, showing that vendors have never particularly had confidence in WEP and have assumed security would be deployed as a basic WLAN functionality by customers. WEP inhibits raw throughput at a ratio of about 50%.

WiFi: WiFi is another name for IEEE 802.11b. It is a trade term promulgated by the Wireless Ethernet Compatibility Alliance (WECA). "WiFi" is used in place of

802.11b in the same way that "Ethernet" is used in place of IEEE 802.3. Products certified as WiFi by WECA are interoperable with each other even if they are from different manufacturers. A user with a WiFi product can use any brand of access point with any other brand of client hardware that is built to the WiFi standard. Contrary to popular belief, “WiFi” does not stand for “wireless fidelity.” WECA chose the term WiFi as a catchy term similar to the term HiFi. Unlike HiFi, however, WiFi has no parent phrase.

WLAN: A Wireless Local Area Network (WLAN) is one in which a mobile user can connect to a LAN through a wireless (radio) connection. The IEEE standard, 802.11, specifies the technologies for WLANs. The standard includes an encryption method, the WEP algorithm.
