2 The WIMAN Command Line Level7 / 87l1 Introduction to WIMAN technologyThe WIMAN product series provides a powerful new technol-ogy for the design of flexible data networks. Integrating a mul-titude of innovative and optimized methods and communicationprotocols, we’ve created a wireless network technology, whichis available for various applications such as campus networking,high speed access for Internet users, and cellular data networksin conurbation areas, etc.In contrast to other available wireless products, the WIMANproduct line integrates the demand for an economic system withhigh data rates, a high range and efficient utilization of the fre-quency-spectrum. The WIMAN System utilizes the most mod-ern spread spectrum technology without using any further en-coding algorithm, and features higher security and noise immu-nity than other existing systems. Applying the frequency hop-ping technique in combination with an intelligent transmissioncontrol algorithm, the ISM frequency range between 2.4 and2.4835 GHz is optimally used.The interfaces provided by the WIMAN unit to attach to thecustomer's terminal equipment complies with the internationalX.21 and V.24/RS232/RJ45 standards allowing a direct connec-tion to any standard personal computer, workstation or main-frame system. For hooking up wired networks (LAN, MAN,WAN), there are various routers available in the form of hard-ware or software solutions.The WIMAN product line provides users with the benefits ofhigh performance and speed in a wireless modem. WIMAN iseasily distinguished from other transmission systems throughseveral remarkable features:
2 The WIMAN Command Line Level8 / 871.1 Transmission Speeds / Frequency RangeAt present, wireless data network technology can be divided intotwo categories: The first category consists of wireless modemswith a small transmission bandwidth. These products are usedfor company networks, cellular networks, CDPD (CellularDigital Packed Data) or GSM (Global System for Mobile com-munication) networks. The second category consists of wirelessmodems with large bandwidth in the ISM range (Industrial Sci-entific Media, frequency range around 2,4 GHz), such as wire-less LAN products.It is possible to cover a large area with the narrow band systems.Some systems are even able to cover a complete country. Theother LAN products specified above operate with substantiallyhigher data transmission rates; however, the range of these sys-tems is limited to approx. 300m/900ft. Therefore, the area of ap-plication is strongly reduced.The WIMAN technology offers the advantages of both the nar-row band systems and the broadband systems. With a clear lineof sight between the antennas, data can be transmitted betweentwo WIMAN radio modems with a rate of up to 2048 KBit/s (atthe data interface) / 512KBit/sec at the wireless interface in du-plex operation over a distance of up to approx. 40km/25miles(FCC version) or up to approx. 5km/3.2miles (ETSI version).Furthermore, WIMAN systems are deployed in a highly scalablemanner similar in nature to a cellular structure. Therefore, it canovercome some of the need for direct line-of-sight.
2 The WIMAN Command Line Level9 / 87l1.2 Frequency Hopping ProcedureAll WIMAN radio modems operate with the modern frequencyhopping procedure. With this procedure, the RF-channel ischanged in very short intervals (all 8 ms). A total of 80 non-overlapping radio channels are available.WIMAN takes advantage of these 80 channels, each with 1MHz of bandwidth, by use of spread spectrum technology (fre-quency hopping).The WIMAN radio modem transmits information packages thathop from one frequency to another, not staying longer than 8 msin a frequency range.As data packets are transmitted and received, the ISP selects theorder of the channels, producing a truly secured line of data.This remarkable feature yields the following important advan-tages:• High security against eavesdropping due to fast changesof the channel,• Resistance to jamming,• Protection against other RF-systems in the same fre-quency band,• High performance with high efficiency,• Possibility of parallel operation of WIMAN connectionsby use of different frequency-hopping patterns.1.3 WIMAN Network TopologyWith the WIMAN technology, bonding can be structured in asimple point-to-point connection, but it is also possible to set upvarious other network topologies. The WIMAN product seriesconsists of three different wireless WIMAN radio-modems:WIMAN STAR: wireless base station for public and privatepoint-to-multi-point networks.WIMAN ACCESS: wireless access node for public and privatepoint-to-multi-point networks,WIMAN LINE: wireless point-to-point connection betweentwo computers or computer networks.
2 The WIMAN Command Line Level10 / 871.4 Basic WIMAN TopologiesAs previously mentioned, the WIMAN technology is not limitedto point-to-point connections. Different network topologies canbe structured. The following chapter introduces some simplenetwork configurations using the WIMAN units to illustratesome of the features of each configuration.1.4.1 Point-to-Point connections with WIMAN LINEWIMAN LINE radio modems enable point-to-point connectionsbetween local area networks, data terminals or individual per-sonal computers. In general, the WIMAN LINE can replace awire communication or a zero-modem cable. At present theWIMAN LINE supports duplex data transmission rates of 256kBit/s at 2FSK WIMAN LineRouter WIMAN Line RouterFigure 1 Point-to-Point connection using WIMAN LINE
2 The WIMAN Command Line Level11 / 87l1.4.2 Cellular Networks using WIMAN STAR and WIMANACCESSOne of the outstanding features of the WIMAN series is its abil-ity to support point-to-multi-point networks with technicallymatured distribution of load between the individual ACCESSdevices (load balancing).Figure 2 shows a typical network environment. WIMANAccessWIMANStarWIMANAccessWIMANAccess Figure 2 wireless access networks with WIMAN STARand WIMAN ACCESSThis network configuration can be used as a wireless connectionto the Internet.The current software-Version supports up to 9 WIMANACCESS per WIMAN STAR. They can be configured to meethigher density of traffic in the networks by use of several syn-chronized parallel WIMAN radio modems.Avoid errors by synchronization of the WIMAN units (seechapter 4.5 on page 53).
2 The WIMAN Command Line Level12 / 871.5 Transmission Protocols1.5.1 Frame RelayThe WIMAN system supports the Frame Relay protocol widelyused at many Telephony companies.It operates smoothly in Frame Relay networks and enables theapplication of commercial Frame Relay compatible Router asswitches on the STAR- and the ACCESS side.Except for the supply of an Internet access, it is additionallypossible to use the WIMAN Frame Relay system for telephonyuses. Therefore, commercial Frame Relay multiplexers fromcompanies such as RAD, NUERA, CISCO, etc. can be used.The Frame Relay support is a software-configurable feature andis starting from the software-Version T.05. This software ver-sion does also support leased line functionality.

2 The WIMAN Command Line Level13 / 87l2 The WIMAN Command Line LevelThe operating system of the WIMAN radio modem has an inte-grated command line interpreter ("Shell") for configuration ofthe WIMAN. Input and output is visible on the input or output-window of a PC terminal program (e.g. TELIX, ZOC).So that communication between the terminal program and theWIMAN can take place, the communication parameters of theterminal program and the WIMAN must correspond.The configuration of the WIMAN radio modem is executed withinstructions on the command line level (“Shell”). There is nodistinction between upper- and lower case characters (except forpasswords).The command line level can be accessed via different interfaces.Successful locking on the command line level is acknowledgedby display of the command line prompt. The factory setting ofthe command line prompt is WIMAN II >.The user may personalize the command line prompt (e.g.DEVICE 1:).2.1 Authorization LevelsThe command line level has two different authorization levelsthat differ in the number of changeable parameters. Therefore,the WIMAN radio modem may be configured by diverselyqualified and permitted persons (e.g. user, Provider).The last character of the command line prompt displays theauthorization level you are in at that time.The authorization levels are represented as follows:• Authorization level 1 WIMAN II >• Authorization level 2 WIMAN II #Each authorization level can be protected with a different pass-word. However, a password for authorization level 2 is alwaysneeded.
2 The WIMAN Command Line Level14 / 872.2 PasswordsPasswords serve to protect the WIMAN from unauthorized ac-cess to the command line level in the different authorization lev-els. All passwords must have a length from four to eight char-acters. For the passwords the following characters may be used:" a... z ", " A... z ", " 0... 9 ", " - ", " @ ", "?", " \ ", " [ ", " ] ", "< ", " > ".NOTE:The WIMAN DOES acknowledge case sensitivity characters forpasswords.AttentionTyping in of any other characters than the ones mentioned abovemay lead to a reset of the WIMAN shell.If no password is assigned for the authorization level one, thecommand line appears when the WIMAN is switched on. Oth-erwise you are asked to enter a password to access the commandline level one.A password for authorization level two is always required. Thispassword cannot be deleted, however it is possible to modifythis password.In case of a false configuration or a forgotten password in thelowest authorization level (e.g. user authorization level) quali-fied personnel are needed to access the unit (e.g. Provider). It ispossible to gain access directly to level two by entering the des-ignated password for that level.With suitable instruction (see chapter 3.5.1, on page 40) you canreset the password for authorization level one.If, for any reason, you are unable to arrive at the necessaryauthorization level any longer and you are thus closed out of thedevice, it is possible to gain access with a master password. Themaster password can only be used after the third unsuccessfulaccess attempt and can only be made via the serial interface.Further information on this issue can be obtained from yourWIMAN Distributor.Attention:The input of the master password can be executed exclusivelyover the RS-232 port and results in resetting of all parameters totheir factory settings. A reconfiguration of the device will benecessary afterwards.
2 The WIMAN Command Line Level15 / 87l2.3 Operation ModesOn the command line level, the following operating modes aredifferentiated with respect to each authorization level:• Command mode and• Configuration mode.In command mode you can view the accepted parameters of thepresent configuration (current config) as well as give the ac-cepted commands for this mode and authorization level (seeChapter 2.6.1 on page 25).In configuration mode you may change only the parameters al-lowed for that specific authorization level.The system software indicates these parameters as “new con-figuration” (new config). You may render certified instructionsfor this level and this mode.Figure 4 shows how to switch between the different authoriza-tion levels and operation modes. pw password[] optional(n) Authorization levelen enableFigure 4 Diagram of the different operating modesserial connection /TelnetReset pw ←↓ [pw] ↑ exit ↑ exit↓Reset Config ←pw→Command Mode(1) →en pwCommand Mode(2)↓ config ↑ exit ↓ config ↑ exitConfig Mode Config Mode
2 The WIMAN Command Line Level16 / 872.4 Configuration DataThe configuration data (values of the adjustable parameters) isclassified into the following three types:• New configuration (new config),• Present configuration (current config) and• Non-volatile configuration (boot config).Figure 5 shows the connections of the three different types ofconfiguration data. The new configuration is created by modification of the pa-rameters in the configuration mode (see Chapter 2). This has noeffect on the current operation. It is possible to produce a newconfiguration by manually changing the parameters or by read-ing-in a parameter text file. In the parameter text file commentsmay be inserted at the start of a line or after an instruction (SeeChapter xxx on page xxx).The present configuration consists of the parameters used bythe system at that time. This configuration can be saved as a textfile.The non-volatile configuration consists of the parameterscalled on and made the present configuration at a strat or restartof the device. Modified parameters (new configuration) can ei-ther be taken over (transfer for present configuration) or rejectedby a query when leaving the configuration mode.The up-to-date parameters (present configuration) can be per-manently taken over by a further query when leaving the com-mand mode (transfer into the non-volatile configuration) ormaintained only up to the next restart.ASCII- command-file ASCII- configuration file(new config) (current config) (boot config)optional optionaloptionaloptionalnecessary Figure 5 Configuration data
2 The WIMAN Command Line Level17 / 87l2.5 Configuration ParametersThe WIMAN radio modems are delivered with a factory-installed standard setup. To adjust the WIMAN to your specificrequirements you can modify different parameters (dependingon the authorization level).The configurable Parameters are classified into the followinggroups:• Parameter for the wireless interface,• Parameter for the serial interface,• Parameter for the network,• Other parameters.All parameter can only be changed in the configuration mode ofthe appropriate level.2.5.1 Parameter for the Wireless InterfaceThe following parameters affect the wireless interface and serveto set up the network configuration. These parametersalso set upcountermeasures against possible disturbances in the operatingfrequency band.The parameter destination determines the destination address ofthe WIMAN, to which all data will be sent.Note:This setting is only available on WIMAN LINE units and is notused on WIMAN STAR and ACCESS units.Authorization Level: 2Preset value: 1Scope: 0 ... 250The parameter FTab determines the frequency-hopping patternbetween the 80 channels. Each WIMAN radio-modem comeswith a factory installed frequency-hopping pattern that cannot bechanged. However, it is possible to create a second frequency-hopping pattern to be used in place of the standard one. In thiscase the new pattern can be set with FTab.Authorization Level: 2DestinationFTab
2 The WIMAN Command Line Level18 / 87The user-defined hopping pattern must be switched on withFtabMode set to USER.Authorization Level: 2Preset value: SystemScope: System, UserThe parameter LoopData sets the hexadecimal value to be sentin a LoopTest.Authorization Level: 2Preset value: FFFFFFFFScope: 00000000 … FFFFFFFFThe parameter LoopMode determines, which bit pattern andframe lengths are to be used with the independent back loop test(see loop test below). This parameter is not available on STARdevices.It is possible to set the values normal, load, long and high. Thevalues function as follows:• NormalPseudo coincidental data is transmitted. All 256 byte valuesoccur equivalently. A break is inserted between two pack-ages. This type of test is to simulate the "normal" datacommunication in a network.• LoadPseudo coincidental data is transmitted. However, in thistype of test it is transmitted with highest possible transferrate.• Long“Stress” data (bit pattern, which lead to a high utilization) istransmitted at a normal transfer rate.• High“Stress” data is transmitted with high transfer rate.Attention:If the looptest is executed in an operating radio net, all valuesexcept normal should be avoided for the parameter LoopMode.Use of any other value may result in malfunction.Authorization Level: 2Preset value: longScope: normal, load, long, highLoopModeFTabModeLoopData
2 The WIMAN Command Line Level19 / 87lThe parameter LoopTest yields a back loop test. If loop test isset to True, the WIMAN begins to transmit test data in backloop operation. Therefore, it is possible to check procedure sta-tistics during the test. This parameter is not available on STARdevices.Authorization Level: 2Preset value: FalseScope: True, FalseThe parameter MaxRetry determines the maximum number of arepeated package dispatching. A package is dispatched againonly in the case of a failed checksum test. If a package fails thechecksum test, the WIMAN tries to send the package again. Thenumber of attempts to resend the package can be determined inMaxRetry.Authorization Level: 2Preset Value: 9Scope: 0 ... 9The parameter NetId determines the network address of theWIMAN. The WIMAN analyses only the data communicationthat is addressed to the network address configured on it. NetIDalso determines which frequency-hopping table is used.Attention:Please note that if several WIMAN networks are situated inclose geographical location identical NetIds may not be used.Authorization Level: 2Preset value: 255Scope: 0 ... 255The parameter NodeId determines the non-standard address of aWIMAN radio modem within a network. A NodeID with thevalue 0 automatically changes the WIMAN radio modem toMASTER operation. NodeIDs of 1... 250 automatically switcha WIMAN radio modem into the SLAVE operation with appro-priate NodeIDs from 1... 250. Two WIMAN radio modems inthe same network (same NetId) may not possess identical No-deIDs. Disturbance would occur and communication would belost until one of the devices is switched off.This effect does not occur, if a serial number for this NodeID isset with the instruction peer (see peer below). In this configura-tion, the WIMAN radio modem with the adjusted serial numberNetIdNodeIDLoopTestMaxRetry
2 The WIMAN Command Line Level20 / 87would function perfectly and all other devices with the sameNetId and NodeId would be ignored.Authorization Level: 1Preset value: 0 (WIMAN Star)Scope: 0 ... 250The parameter RadioPower activates the normal operation orswitches into a low power mode (around 0 dBm, regardless ofthe Region or Antenna setting). When there is only a small dis-tance between a STAR and ACCESS the transmitting power canbe scaled down to avoid overriding of the input-stage.Authorization Level: 2Preset value: NormalScope: Normal, LowThe parameter Antenna specifies the type of antenna used withthe WIMAN and thus determines the specific settings (e.g.transmit power) required for that type of antenna.Authorization Level: 2Preset value: 8mn360Scope: 2mn360, 8mn360, 85pl76, 16pl27,24pf20In addition to the parameter Antenna, the parameter Region setsthe WIMAN radio to the specific settings required in that spe-cific region (output power, frequency-range, etc.).Authorization Level: 2Preset value: depending on regionScope: 1 valid for ETSI-compliantoperation2 valid for FCC-compliantoperationNote:Incorret setting of the parameters 'Antenna' and 'Region' maylead to non-permitted behaviour of the unit and will void theright of operation !If you are not sure which operation mode the WIMAN unit mustcomply with, please refer to your local distributor or manufac-turer of this system.RadioPowerRegionAntenna
2 The WIMAN Command Line Level21 / 87lThe parameter MaxNodeId determines the maximum number ofdevices that are connected to a STAR.Authorization Level: 2Preset value: 1Scope: 1 … 250The parameter Location can be edited freely to determine the lo-cation of the IWMAN radio modem, e.g. Water_Tower01 orrooftop.Authorization Level: 2Preset value: default-locationScope: No value2.5.2 Parameter for the Serial Configuration InterfaceThe following parameters serve for the communication with theserial configuration interface and are important for the correctcommunication with the command line level.The parameter ConBaudrate determines the Baud rate that canbe transferred over the RS-232-interface for configuring theWIMAN.Authorization Level: 1Preset value: 9600Scope: 300, 1200, 2400, 4800, 9600, 19200, 38400, 57600The Parameter ConDataBit determines the length of the data bitswhen transferring data over the RS 232-interface.Authorization Level: 2Preset value: 8Scope: 7, 8The parameter ConHandShake determines the handshakingmode during a transfer on RS-232-interface. It can be selectedbetween a software-controlled handshaking and no handshaking.With software-controlled handshaking the control sequencesXon and Xoff are used.Authorization Level: 2Preset value: softScope: soft, none (no handshaking)ConBaudrateConDataBitConHandShakeLocationMaxNodeId
2 The WIMAN Command Line Level22 / 87The parameter ConPageSize indicates, how many lines in the re-spective command line window (terminal window over RS-232-interface) are to be represented, before the continuous output ofthe parameters is stopped. The size of an output page is thus fi-nally determined.Authorization Level: 2Preset value: 24Scope: 10 ... 100The parameter ConPauseMode determines if the output on thedisplay shall be stopped after the number of lines given withConPageSize or not.Authorization Level: 2Preset value: OnScope: On, OffThe parameter ConParity determines the type of the paritycheck on the serial RS-232-interface.Authorization Level: 2Preset value: none (no parity check)Scope: none, odd, evenThe parameter ConStopBit determines, how many stop bits aresupposed to follow the data bits on the serial RS-232-interface.Authorization Level: 2Preset value: 1Scope: 1, 22.5.3 Parameter for the serial data InterfaceThe following parameters serve for the configuration of the se-rial data interface and are important for correct data exchangebetween the Router and the WIMAN radio data modem.The parameter SerBaudrate determines the Baud rate for thedata communication on the X21-interface.Authorization Level: 1Preset value: 2048000SerBaudrateConParityConStopBitConPageSizeConPauseMode

For instructions on how to set up apassword for authorization level one, see Chapter 3.5.1, page 40.The instruction del Passwd console deletes the password forauthorization level one (console). For mor information seeChapter 3.5.2, page 41.The instruction passwd enable permits the designation of apassword for access to authorization level two (Enable). Whenentering the password, be sure tu use the specified charactersonly (see page 14). For instructions on how to set up a passwordfor authorization level two, please refer to Chapter 3.5.3,page 40.The instruction Enable enables you to switch from the instruc-tion mode of the authorization level one into the command modeof the authorization level two (see page 25). To enter theauthorization level two a password is always required.2.6.2 Instructions for manipulating and transferring ofConfiguration DataThe instruction Checkcfg checks if all the parameters are validand entered correctly. This instruction can only be issued in con-figuration mode.The instruction Config enables to change from the commandmode of the respective authorization level into the configurationmode (see page 25). A successful transition into the configura-tion mode is displayed by the term (config) behind the com-mand-line prompt and before the indication of the authorizationlevels (located in parentheses). The following example showsthe factory-installed command-line prompt for authorizationlevel two:WIMAN II (config) #Del PasswdconsoleEnableConfigPasswd enablecheckcfg
2 The WIMAN Command Line Level27 / 87lThe command Del Config enables the factory-installed presetparameter-values to be transferred from the non-volatile con-figuration to the new configuration. All modifications enteredbefore will be overwritten. This command can be given in con-figuration mode only.The command Del < paraname > enables a transferring of thefactory-installed preset parameter-value for the parameter de-fined in < parname > from the non-volatile configuration intothe new configuration. All modifications of < parname > areoverwritten with defined parameters. In contrast to the instruc-tion Del Config, it is possible to overwrite directed parameterswith the factory-installed defaults. This instruction can be issuedin the configuration mode only.The command exit enables you to leave the configuration modeor the command mode.When leaving the config mode after having changed at least oneparameter, you will be asked whether these modifications shouldbe made the present configuration.You now have the choice to:• Make the modifications the present configuration and leavethe config mode by entering ‘y’,• Discard the modifications to the present configuration andleave the config-mode by entering ‘n’, or,• stay in configuration mode and make the modifications onlythe new configuration by entering ‘c’.When leaving the command mode after having changed at leastone parameter (at least one parameter was modified in the con-figuration mode and the modification was made the present con-figuration), You will also be asked if these modifications are tobe considered with the next restart (They will be transferred intothe non-volatile configuration).You now have the choice to:• transfer the modifications to the non-volatile configurationand leave the command mode by entering ‘y’,• discard all modifications made and leave the commandmode by entering ‘n’ or• stay in the command mode and keep the modification of theparameters exclusively as present configuration by entering‘c’.ExitDel <paraname>Del Config

However, aesthetic views aresecondary in respect to a proper operation of the WIMAN.• Be sure that no other antenna systems operating in the2,4 GHz ISM band are installed at the selected installationpoint. If such an antenna system is installed there, contactyour WIMAN Distributor.
47 / 87l4 Hardware Installation• Be sure to discuss the details of installation with the cus-tomer in respect to the local construction and homeownerregulations.4.1.5 First Reception TestThis first reception test serves to determine if the optimum fieldstrength can be obtained from the installation place and adjust-ment of the WIMAN outdoor sets.Further information about reception tests can be found in chap-ter 5 on page 55.4.1.6 Installation of the Attachment Set and the OutdoorHousingTo set up the outdoor housing:1. Assemble the outdoor housing.2. Attach the antenna to the outdoor box with the plug facingdown.3. Loosen the four screws on the front of the outdoor housingand remove the cover.4. Loosen the four fixing bolts for the WIMAN mountingplate on the inside and remove it.5. Place the WIMAN inside the housing with the LEDs facingupwards and the backside (with the connector) towards theopening of the housing.6. Lead a cable strap through the two holes in the mountingplate (the cable strap later serves for the attachment of thehybrid cable of the type 3).7. Secure the mounting plate above the WIMAN.8. Connect the appropriate ends of the hybrid cable of thetype 3 with the 37Pin Sub-D-interface and to the currentsupply link.9. Place the excess cable in the space between the WIMANand the outdoor housing in such a way that the 25pin plugconnector is hanging over the front the mounting plate.10. Connect the data cable with the hybrid cable and secure theplug connectors with the cable strap. To ensure positiveconnection at all times, install 2 hex nuts between the con-nectors.11. Use the screws, wearing parts and pegs to install the appro-priate attachment set onto the roof or at the wall.
48 / 874 Hardware Installation- Use the j-shaped wall mount if you are installing theWIMAN on the side of the building directly facing the ra-dio tower.Use the aluminum mast mounting kit if you are installingthe WIMAN not facing the radio tower directly due to anobstacle (e.g. rear side of a wall etc.).Use the tile roof mounting set if you are installing theWIMAN to a roof with roofing tiles.4.1.7 Second Reception TestPerform a second reception test to ensure that the selected placeof installation and the selected adjustments offer a sufficient ra-dio reception.Separate the current supply and the RS232-plug from the Hy-brid-2-cable on the WIMAN radio modem.Further information of the execution of a receipt test can be ob-tained in chapter 5 on page 55.After the radio test is completed, reconnect the current supplyand the RS232-plug to the Hybrid-2-cable on the WIMAN.4.1.8 Installation of the data cableWith some installations, it is possible to use a prefabricated ca-ble of desired length with two 25pin Sub-D plug connectors.However, this is not possible with most installations. If no pre-fabricated cable can to be used, it is advisable to attach a plugconnector at one end of the cable prior to installation.Lay the data cable from the outside inward. Make sure the endwith the 25pin Sub-D connector is outside. It is substantiallysimpler to solder the second plug connector on in the internalarea than in the external area.Be sure that the data cable is sufficiently fixed to the mountingsets, the mast and to the wall.Wind up all surplus cables and stow them away. Wind the cableup in one or two turns. This measure serves as additional light-ning protection for the router.4.1.9 Mounting of the DB25-plug interfaces at the insideend of the data cableSolder the two 25pin plug connectors to the data cable accordingto the pin allocation plans specified in chapter 10.
49 / 87l4 Hardware Installation4.1.10 Final reception test with installed data cableThe final reception test is necessary for two reasons: First to ex-amine the assembly position of the WIMAN, second, and moreimportantly, to test the data link between the Router and theWIMAN.You will find details to the reception tests in chapter 6 onpage 58.To perform the test, connect your Laptop to the RS232-interfaceat the Hybrid-cable type 2.If there is no connection to the WIMAN or if the connection isunusually slow, follow the instructions specified below to locatethe source of error.1. Make sure that the terminal program is adjusted to the cor-rect Baud rate (9600 Bit/s).2. The power-LED lights up in green when sufficient operat-ing voltage is supplied, and in orange if the WIMAN per-forms a looptest. If an internal error occurred the powerLED lights up in red.3. Make sure that the RS-232 cable and the power-supply arecorrectly connected at both ends of the data cable.4. Double-check the solder joints and the pin-allocation insidethe plugs of the data cable.5. Check the hybrid cables by alternating them one at a time.4.1.11 Check the statistics of the X.21-interfaceTo check the statistics of the X.21-interface you must first testthe connections between the WIMAN and the Router.To test the connections you must:1. Ensure that Router is attached correctly and switched on.2. Enter the instruction "stat serial ext".This instruction displays information to the data transmittedvia the Serial-interface. The last line of the display-outputshould look as follows.Line State: Control (C): ON Indication (I): ONIf “OFF” appears in either of the signals, a connection error hasoccurred. Follow the instructions given below to locate thesource of the error:1. Check the X.21-connections at both ends of the data cablefor correct fit.
50 / 874 Hardware Installation2. Double-check the solder joints and the pin-allocation insidethe plugs of the data cable.3. Check the hybrid cables by alternating them one at a time.4.2 Installation of a WIMAN Star4.2.1 Additional necessary componentsChecklist:In addition to the parts specified in Chapter 4.1.2, page 45, thefollowing components are needed for the installation of aWIMAN STAR:• Tower standoffs• 1 WIMAN Access with Indoor-Set for testing purposes• 1 Router for testing• Configuration files for all radio modems4.2.2 PreparationTo install a WIMAN star:1. Label all WIMAN units according to the convention:XX-YYY-ZZZ.• XX = LM (Line Master), LS (Line Slave), SM (Star Multi-point), AS (Access)• YYY= NetId (0-255)• ZZZ = adjustment of the antenna (0 -359°) – towards north.2. Install the WIMAN radio modem and Typ-3-Hybrid cablein the outdoor housings.3. Label the remaining WIMAN utensils according to theconvention indicated above. You should label:
51 / 87l4 Hardware Installation- All data cables (upper and lower end)- All small external housings (if used)- All antennas on large external housings (if used)- the radio modem designated as synchronization mas-ters, with the additional designation "Sync master",4.3 Installation at the Radio Tower4.3.1 Installing the tower standoff at the radio mast4.3.2 Installing the WIMAN hardware at the tower standoffAttach the WIMAN hardware (external housing and antennas)to the tower standoff at the suitable positions and align. If aWIMAN is to take over the function of the synchronization-master and is not clocked from a remote location, always use theunit aligned to the north (0º) as the synchronization master.4.3.3 InstallationInstall all data cables. Connect the data cables with the Hybridcables coming from the WIMAN radio modems.Attention:For correct function and error-free installation, be sure that thesync cable is installed before testing.4.3.4 Start testsNow test all installed components on correct function and in-stallation. You find a specification of the tests in chapter 6 onpage 58.4.3.5 Checking the antenna adjustment• Check to see that all antennas are facing the correct direc-tion.• Note the adjustments of all antennas.4.3.6 Test all devices• Make sure all devices on the radio tower are switched onand are connected to the synchronization cable.• Test each WIMAN radio modem again (see chapter 6,page 58.) to make sure that there is no error caused by thesynchronization cable.
52 / 874 Hardware Installation4.3.7 Save all configuration data of the WIMAN radio mo-dems at the radio tower• Use the same name conventions used for the cables andWIMAN radio modems.• Record the following information with a terminal program:- Parameter („show“-command)- Statistics („stat“-command)4.4 GroundingIt is extremely important to ground all installed devices on theradio tower. This will reduce the amount of damage shouldlightning strike. The following steps will also help to reducepossible damage caused by lightning:• Do not mount the WIMAN at the highest point of the radiotower. This is the point most likely to be struck by light-ning.• Check that the outdoor housing and the tower standoffsform a well-grounded metal-on-metal connection with thetower frame.• Avoid using rubber washers or seals.• Install lightning protection devices between the data cableand the hybrid-sets on both the top and bottom of the tower.• Ground the data cable to the tower at (a minimum of) threedifferent places. (1) to the center of the tower, (2) to thebase of the tower where the cable bends (before the bridgefrom the tower to the shed) and (3) before the cable runsinto the equipment shed. The best way to do this is to stripaway the outer casing of the cable and affix a groundingclamp to the cable shielding, then connect this clamp to asecond one which is fixed to the tower.• Make sure that all equipment (Switches, Routers, etc.) at thebase of the tower is properly grounded to the rack in whichit is mounted. Also make sure that the rack itself is properlygrounded.
4 Hardware Installation53 / 87l4.5 Burst-SynchronisationBurst-synchronization is the coordination process of frequencyhopping tables, receipt, and points of transmitting time for sev-eral WIMAN networks within the same geographical area.Burst-synchronization is achieved by both hardware and soft-ware items. The hardware item is a synchronization cable, whichis only a wire, which connects the X.21-interfaces among them-selves.For the X.21 Interface, the synchronization cable is enclosed inthe hybrid cable type 3. This is connected to further radio mo-dems with additional cables and special T-connectors.The software section for synchronization consists of the pa-rameter SyncMode, which is to be entered in the basic configu-ration of a master or a Slave.One master radio modem (STAR or LINE) is determined assynchronization master for all radio modems at that location.The synchronization master is adjusted as follows:• SyncMode = MasterAll further master radio modems should be adjusted as follows:• SyncMode = Slave4.6 Extended Point-to-Point ConnectionsAn estendet Point-to-Point connection can be structured by ar-ranging two WIMAN LINE “back-to-back”. For this applica-tion, additional hardware is necessary. Please contact yourWIMAN supplier.For an extended point-to-point connection the parameterSyncMode has to be set to the base WIMAN LINE configura-tion.The example configurations specified below refer to an ex-tended X.21 Point-to-Point-connection. In this structure, theWIMAN LINE Slave 1 is coupled to the WIMAN LINE Master2.

5 Reception quality and transmission speeds55 / 87l5 Reception quality and transmission speedsFor the examination of the receipt quality as well as to error de-tection, test loops can be generated. The type of test loop can beinfluenced by the configuration of the parameters LoopData,LoopMode and LoopTest.The parameter LoopData enables the setting of the Byte-valuesthat are to be generated (see page 18). This parameter can beproduced on a WIMAN ACCESS only.The parameter LoopTest enables a switching to a test loop, withwhich the data, which can be transmitted, is produced independ-ently by the WIMAN radio modem (see page 19).This test loop can already be activated in the lowest authoriza-tion level and is, in combination with the statistics analysis onthe wireless interface, an outstanding inspection procedure forradio communication.The parameter LoopMode determines, which bit pattern will betransferred with the back loop in the loop test operation from theWIMAN radio modem (see page 18)Attention:If the back loop test is execute in an operating radio net, avoidall values except normal. Use of any other value may result inloss of performance.5.1 Configuration of a TestLoop with IndependentlyGenerated Data Communication1. Access the command line level of authorization level one(see chapter 2 on page 13) and change into the configura-tion mode. You will see an output similar to:WIMAN-II (config) >2. Type in the command looptest true.3. Check with show looptest the value for the parameterLooptest. This should now be switched to true. The fol-lowing output appears:WIMAN-II (config) > show looptestLoopTest false ( true)The present and the new configuration (in parentheses) ofthe parameter are displayed.
5 Reception quality and transmission speeds56 / 874. To take over the modifications into the current configura-tion leave the configuration mode by entering the commandexit (see page 27).The following output appears:Configuration changed, do you want to save (y)es/ (n)o / (c)ancel ?You now have the choice:- To transfer the new configuration into the current con-figuration and to leave the configuration mode bypressing the key „y“,- To discard the modification but to leave the configura-tion mode anyway by pressing the key „n“ or- To not take over the modification into the current con-figuration but to stay in configuration mode by press-ing the key „c“.Press the „y“ key to activate the looptest. The modificationof the parameter becomes part of the current configurationand the WIMAN starts transmitting bit samples.5.2 Test after a Radio Tower Installation with Syn-chronisationAfter all devices are correctly installed, a final test must be exe-cuted. This final test checks if all devices are installed correctlyand whether a trouble free transmitting and receiving mode ispossible.• Switch on the first WIMAN radio modem. Always beginwith the WIMAN determined as synchronization master.• Radio test- If the synchronization Master is a WIMAN STAR or aWIMAN LINE Master, conduct a loop back test froma properly configured WIMAN ACCESS or LINESlave.- It the synchronization Master is a LINE Slave, conducta loop back test from its LINE Master.• Check the X.21-interface by connecting the X.21-plug ofthe Hybrid cable type-2 to the Router.
5 Reception quality and transmission speeds57 / 87l- For the WIMAN STAR enter the commands „stat wl“and „stat wl<nodeID>“ to ensure proper functioning ofthe data exchange.- For the WIMAN LINE enter the command „stat sync“to check the setting of both signals (both signals haveto be set to „On“).5.2.1 Continue the Tests• Switch on the WIMAN radio modem next to the synchroni-zation master.• Switch off the synchronization master.• Perform a reception test.• Check the X.21-interface (see chapter X.21-Test above).• Switch the synchronization master back on.• Perform another reception test to make sure the synchroni-zation cable does not produce any errors (the radio statisticsshould not differ substantially from the preceding ones).5.2.2 Test the Remaining Modules• Switch on the next WIMAN.• Switch off all WIMAN radio modems that were tested be-fore.• Perform a reception test.• Check the X.21-interface (see chapter X.21-Test above).• Switch on all WIMAN units that were tested before.• Connect the synchronization cable to the last testedWIMAN radio modem.• Perform another reception test to make sure the synchroni-zation cable does not produce any errors (the radio statisticsshould not differ substantially from the preceding ones).5.3 Transmission Speeds5.3.1 FTP-Download from an FTP-ServerThe maximum transmission speed of the WIMAN radio modemat optimum conditions is about 25 … 30 Kbytes/s at 2FSK andabout 55 … 62 Kbytes/s at 4FSK (depending on the extend ofutilization of the network).

7 Troubleshooting66 / 877 Troubleshooting7.1 Techniques and Methodologies Used for Trou-bleshooting7.1.1 General ProblemsThis section lists some common problems that may occur andcause a malfunction in the WIMAN system:Bad RF-Link between STAR (Master) and ACCESS (Slave):• STAR units are not synchronized ! see stat sync• Bad hardware on the STAR or the ACCESS- Check RF statistics from the STAR to other ACCESS de-vices ! see stat wl extIf all other connections are functioning properly,STAR is not defective.• If the star is working correctly consider the following ques-tions:- Is the ACCESS device configured correctly (correct STAR,correct sector)?- Are there any obstacles between the STAR and theACCESS?- Is the antenna cable attached correctly?- Is the antenna adjustment correctly?- Is the ACCESS device itself defective (defective transmit-ting or receiving part)? ! If so, exchange the device.- Are two ACCESS devices within a network configured withthe same NodeID? Check the ACCESS configuration, thenetwork configuration and the documentation of the otherACCESS radio modems within in the same network.No data communication from the STAR to the ACCESS:• Check the radio connection between the ACCESS and theSTAR.• Check the wiring of the STAR and ACCESS- Check the other radio modems attached to this STARIf data can be transmitted to the other ACCESS de-vices then the wiring at the STAR is OK.
7 Troubleshooting67 / 87lIf you are still uncertain whether there is a problemwith the wiring of the STAR, proceed as follows:Check the statistics with the commands stat serial extand stat wl<NodeID>. If you transmit a Ping, theRx and Tx-counter should be increased.Check whether the data cable is wired according to thespecifications shown in chapter 10, page 82.Check all modules for correct wiring.Check the hybrid cables.Check the interface converters.Check the cross over cables.- Check the wiring on the ACCESS:Check the statistics with the commands stat serial ext(see page 49) at the ACCESS-side. If you transmita Ping, the Rx and Tx-counters should increase.Check whether the data cable is wired according to thespecifications shown in chapter 10 on page 82.Check the wiring of all modules.Check the hybrid cables.Check the routing tables.• With the instruction stat hw compare the serial number en-tered in the device table (peer-table) with the actual serialnumber of the device. If the serial number does not match,all data packages will be discarded. Enter the following todelete an existing entry in the device table:PEER <NodeID> <ENTER>Afterwards reset the device.• Check whether the looptest at the ACCESS radio modem isstill active (show looptest). The Parameter „LoopTest“ mustbe set to „false“.• Defective Router at the customer side:- Check the configuration- Check the Hardware• PVC- PVC was built on the wrong port- PVC was built with wrong DLCI (according to the appro-priate NodeID of the ACCESS)• Routing tables
7 Troubleshooting68 / 87• Bad port on the switch- Check other customers who are attached to the same STAR- In case no further customers are attached to the sameSTAR, try attaching the device to another port.WIMAN Baud rate parameters are not adjusted correctly:If the WIMAN radio modem does not interface with the termi-nal program, the Baud rate may be set incorrectly on theWIMAN and/or the terminal program.Frequency table adjusted incorrectlyIf the WIMAN Slave cannot construct synchronized connectionsand you are using generated frequency tables, check that the pa-rameter "FtabMode" is adjusted to "user". Make sure that allparameters are configured correctly.Parameter destination not adjusted correctly (LINE only)This situation cannot occur after a loop test. If the Socket pro-gram cannot structure a connection, check the network and en-sure that all parameters "destination" are set to the correct value.Baud rate in the Socket program not set correctlyIf the Socket program cannot construct a connection, it could bethat the Baud rate is set incorrectly on the Socket programand/or the WIMAN.Parameter NodeID not set correctlyIf an ACCESS radio modem receives synchronization impulses,but no data can be transmitted, it could be that the parameterNodeID is adjusted incorrectly. The double assignment of anode number in the same network leads to malfunctioning.Serial number does not correspond with the device table(Peertable)If the WIMAN STAR is adjusted to a serial number that differsfrom the one used in the Peertable, malfunction may occur.IP-Parameter in the Socket-program not set properlyIf the Socket program over the ACCESS radio modem cannotconstruct a connection, check whether all IP parameters are ad-justed correctly.Damaged or defective antenna cableDamaged or defective synchronization cable
7 Troubleshooting69 / 87lAny of these problems may lead to poor or no radio communi-cation. Check the antenna cables for damages. If there are nodamages, check the synchronization connection. If the problempersists, the WIMAN may need to be replaced.7.1.2 Troubleshooting with Radio Tower Installations• If the WIMAN radio modem can not be accessed over theRS-232-interface, the problem may be caused by:- A non-corresponding Baud rate of the terminal program andthe WIMAN (usually the Baud rate is adjusted to 9600Baud)- Incorrectly attached cables- Faulty Hybrid-2 or Hybrid-3-cables. Exchange the Hybrid-2-cable first and then the Hybrid-3-cable (if necessary).- Faulty contacts inside the data cable plug. Check the con-figuration and transmission with an extra 25pin data ca-ble.• In case the ACCESS can get no RF-synchronization signal(indicated by the Status-LED at the front side of the unit) orif the synchronization signal reception is periodically inter-rupted, the problem may be caused by:- Incorrect configuration of the ACCESS or STAR. Checkwhether all parameters are correct.- The operating voltage at the star radio modem is too low. Ifthe operating voltage at the WIMAN radio modem dropsbelow the given threshold value, a restart is performedautomatically. It is advisable to constantly apply a volt-age at the radio modem by at least 12V.- Defective or unattached antenna cable,- A Faulty Hybrid-2 or Hybrid-3-cable. Replace the Hybrid-2-cable first and then the Hybrid-3-cable (if necessary).- Defective RF filters.- Defective WIMAN STAR or ACCESS.- Faulty contacts inside the data cable plug. Check for perfectconfiguration and transmission with an additional 25pindata cable.- Defective synchronization cable (short-circuit in the plug)of and to the testing device.- Defective T-connector (short-circuit)
