III. Installation procedure 1.
PAGE 31
General recommendation for antennas placement are the following: • Install antennas as high as possible over specific level. In case of flat surface - it will be ground level, in case of vegetation and forest – it will be tree heights, in urban environment – it will be the highest building in the observed area (specific level definition).
PAGE 32
current goes through the coaxial cable which grounds ODU clamp with the mast – the mast is grounded via the grounding contour. The direct lightning strike to the STP service cable (ODU-IDU) is partially terminated on the grounded IDU case. Partial termination means that the direct lightning strike will probably destroy an STP cable. The service cable pickups from the electromagnetic impulses are terminated on the IDU case by the winding shield, and further – on the IDU grounding.
PAGE 33
Grounding w hen using I DU-LA Antenna must be placed on the mast on the level that is at least 1 meter lower than a mast’s top. In this case it is of big probability that the lightning strikes the mast and not the antenna. The mast is to be grounded on the grounding contour according to your local standards. When the lightning strikes the antenna, the current goes through the coaxial cable which grounds ODU clamp with the mast – the mast is grounded via the grounding contour.
PAGE 34
accumulation on the ODU case if there are some problems with its connection to the grounding contour. Antenna pole, tower, ODU and lightning arrestor must be connected to the first common grounding contour. Cable thickness must be not less than 10AWG using corrosion-steady connectors. Grounding contour development must be done by the skilled personnel. A special attention should be paid if antenna used is not DC-shorted. In this case additional lightning arrestor should be used between the antenna and ODU.
PAGE 35
• Use build-in InfiNet Wireless Device features. These features allow evaluating current channel/signal quality and perform precise antenna alignment Omni-directional and sector antennas have a wide radiation diagram width, thus usually they either do not require a very precise alignment or it is just not necessary due to radio link requirements. Antenna polarization must be taken into consideration while installation. In most cases omni-directional and sector antennas have a vertical polarization.

By default the system displays daily data logs. All charts support simultaneous zooming to improve usability: once the user zooms into a certain region on any of the charts, all other charts are re-scaled automatically to display the data collected during the same period of time. Critical events like link outages or frequency swaps are marked by small red balloons on the bottom of each graph. Hover over each balloon for details. Working with the charts: • Select chart region to zoom in.
PAGE 80
This chart displays measured RX (green) and TX (blue) signal levels. Red regions represent link outages. Default graph uses CINR measurement method, however RSSI method can be selected from the drop-down menu. RX/TX Retries (%) This chart displays retry percentage – an important parameter, that provides a quick estimation of the link quality. Similar to the previous graphs RX retries are represented by the green lines, TX retries – by the blue lines and link outages – by the red lines.
PAGE 81
The Bitrate chart displays established link bitrate. Note that the bitrate is not the same as link throughput but rather represents link quality. Link load charts (pps & Kbps) Load charts display actual link load information either in real time of for the given period.

PAGE 90
ΙΙΙ. Configuration (CLI) 1. Initial settings configuration procedure Before starting new device, one should perform initial configuration. The configuration can be performed either using serial console port or using Telnet protocol. In order to configure the device using Console port, follow the instructions below: • Device should be connected with host serial interface, using InfiNet Console cable • Start any terminal emulation software (e.g.
PAGE 91
• rfX.0 - radio interfaces. See device’s labeling or use “ifconfig -a” command to learn your radio interfaces • pppX – point-to-point interfaces • tunX - interfaces used for IPIP tunnels building • vlanX – interfaces supporting VLAN 802.1q tagging All configured interfaces of the Device can be reviewed using the following command: ifconfig -a 3. Command line interface (CLI) For device’s management and configuration a Unix-like command line language is used.
PAGE 92
In order to save your configuration “config save” command is used. It saves the current system configuration in the Device's flash memory for subsequent permanent use. All modifications to the system parameters, if not saved by this command, are valid only during the current session (until the system reset occurs). I m port/ export Export/import of the device’s configuration is performed using “config export” and “config import” commands correspondingly.
PAGE 93
Therefore, the possible formats to specify IP-addresses are: nn.nn.nn.nn (no mask is used) nn.nn.nn.nn/N (N is the bit length of the mask) nn.nn.nn.nn:xxx.xxx.xxx.xxx (xxx.xxx.xxx.xxx is the numerical value of the mask) Example: The 192.168.9.0/24 address describes the network address 192.168.9.0 and the mask with leading 24 bits on. The same set of addresses may be denoted as 192.168.9.0:255.255.255.0. 6.

to a radio interface as a whole, and means only that you want to use this mode in this device; but the BURST protocol can only work for destinations where it is also enabled at the other end, and only if the MINT protocol is used at both sides. Burst enabling does not induce any changes in the work of other devices in the network. To disable “burst” mode use “-burst” parameter in “rfconfig” command. • distance: this parameter is used to set the exact distance value between two devices (in kilometers).
PAGE 95
Ις. Link setup 1. Preliminary decisions Bitrate selection Overall link performance is greatly depends on the right bitrate selection. Wrong bitrate of a radio link in most cases lowers its performance characteristics. In the result subscribers are getting bad services. IW MINT architecture makes bitrate selection process fully automatic. Using IW proprietary Link Forecasting and Active Testing algorithms MINT chooses the optimal radio transmission rate individually for each connected subscriber device.
PAGE 96
Range/Bitrate calculator view. To use the calculator: 1. Set needed frequency range in “Band” field. 2. Set NLOS parameters in “Path type” field. 3. Set radio channel width in “Bandwidth” field. 4. For Site 1 and Site 2 define device model, device’s max output, antenna gain and feeder loss. 5. Press “Calculate” button. The results will be listed in a table below. For each available Bitrate value you will see corresponding distances in kilometers for “worst”, “mean” and “optimal” environment conditions.
PAGE 97
Ltest can work in standard, alignment and bandwidth modes. Standard mode: In standard mode Ltest measures signal levels, retries, lost packets and acks. To start Ltest in this mode: lt rf5.0 When «ltest» command starts it will show you output information that contains testing results.
PAGE 98
In some cases signal level that is less than 12 may be enough for radio link operation. In this case one has to be guided by such parameters as number of retries, number of undelivered packets and number of undelivered acks. If the number of undelivered packets and the number of undelivered acks is null, the number of retries is small and all these parameters are constant in time then the radio link, most often, will be operating properly. 3.
PAGE 99
• -tu [seconds] – Unidirectional test: packets are transmitted only from the current side to the specified address (“target” option) • -tb [seconds] – Bidirectional test: packets are transmitted in both directions “Seconds” parameter allows setting test period (5 seconds by default). Maximum value is 60 seconds. To start Ltest in this mode: lt rf5.

The picture above shows the output of review mode. To run the review mode please type the following command: muffer review Once the link is established you can use this mode to review the activity on the configured for frequency for the link. If no activity is observed that means that the signal from the remote side is being broken by the interference sources or by the obstacles on the signal propagation path.
PAGE 101
Like in review mode this regime provides with the information about a current activity but on the configured frequency. To run the review mode please type the following command: muffer mac2 Statistics The statistics gathering is used for estimating link load intensity and per client. The amount of packets sent and received, and the number of retransmissions is shown for each MAC address participating in the data exchange. The statistics output is presented in the picture below.
PAGE 102
• Concerning the fact that statistics module outputs the information for each MAC-address separately, you can reveal the problem for some specific unit on the wireless network The “muffer stat” command shows the statistics only from registered devices. To view statistics type the following command: muffer stat To reset all counters please type muffer stat clear Other modes of muffer The muffer also has the following modes: • mac mode.

To run load meter like it is shown above, please type: loadm –l Acquiring interfaces statistics Interface statistics can be acquired using netstat module which includes two modes: • Routing tables output (using “-r” parameter with the command) • Interfaces statistics output (using “-i” parameter with the command) Below picture shows the example of interfaces statistics output. If the interface has several aliases the statistics is still measured for physical interface in a whole.

1. For turning InfiNet Wireless RapidView-1 on simply push «Power button». 2. Device LEDs will light up for 2 seconds. 3. Device will perform constant tries to connect to ODU. If device’s power is normal Power/ODU connection LED (1) will blink 1 time per second. If device’s power is low LED 1 will blink 4 times per second in turn with not lighting intervals. 4. Once ODU link is established LED 1 stops blinking (if power is normal) and device’s interfaces status are shown by LEDs 2-6. 5.

LEDs Function 1. Power/ODU connection LED Shows diagnostic device power status and diagnostic device-ODU connection status. 2. Radio link LEDs Show whether radio link is established on certain ODU’s radio interface. Constant lighting — diagnostic device-ODU connection established, diagnostic device power is normal. Blinking 1 time per second — diagnostic device power is normal, diagnostic device-ODU connection is not established.

ςΙ. Recommendations 1. Using InfiNet devices for High Bitrates Using InfiNet devices on bitrates 48 and 54 Mbps (standard series), 104…130 Mbps (Xm-series, 20 MHz) and 240…300 Mbps (Xm-series, 40 MHz) has specific requirements because of low noise immunity of high-order modulation techniques (64 QAM). One should take all possible precautions to prevent exceeding of parasite signals over receiver sensitivity threshold. The problem is aggravated by the presence of this parasite signal in entire spectrum.

Every step in bitrate increasing requires 3 dB step improvements SNR. Asymmetry in 8 times corresponds to 9 dB. It means that without link quality losses we can have 2 times bitrate difference between upstream and downstream. In order to maintain energetic parameters, we have to increase base station output power by 9 dB by means of built-in amplifier (for example to use 300-500mW devices). 4.
