LigoWave Page 7 Purpose This document provides information and procedures on installation, setup, configuration, and management of the PTP unit. Definitions, Acronyms and Abbreviations The following typographic conventions and symbols are used throughout this document: Additional information that may be helpful but which is not required. Important information that should be observed. bold Menu commands, buttons, input fields, links, and configuration keys are displayed in bold italic References to sections inside the document are displayed in italic. code File names, directory names, form names, system-generated output, and user typed entries are displayed in constant-width type About This Guide

LigoWave Page 8 The PTP link consists of two units, one on each end: Master and Slave. Master unit operates as an access point; therefore the Slave connects to the Master and operates as a client. Figure 1 – Point-to-Point Link Elements From the point of view of the administrator the Local unit is the one with the direct connection to the Web management interfaceand the Remote unit is the one which is connected to the Local unit in PTP link. The concept of the Local unit and the Remote unit is not related to the operating mode (Master or Slave). This terminology will be used throughout the manual, particularly in the description of statistics. Introduction

LigoWave Page 9 Application Examples Building to Building Connectivity Use the PTP for building to building connectivity in the private networks such as campus building connections, corporate building connections, universities and schools that wish to own and manage their own networks and eliminate the costly recurring charges from service providers. The same connectivity is perfect to build backup/failover connections. Figure 2 – Building to Building Connectivity Backhaul The PTP offers a cost effective solution made for WISPs, Cellular Carrier, Telco, ISPs, enabling operators to quickly and efficiently expand their networks.

After successful administrator log on you will see the main page of the PTP unit Web management interface. The PTP unit now is ready for configuration. For further instructions on configuration refer to the respective chapter Web Management. Accessing the PTP Unit’s Web Management

LigoWave Page 12 Default Settings The default settings of the PTP unit configuration parameters are listed in the tablebelow: Parameter Default value IP address 192.168.2.66 Netmask 255.255.255.0 Login admin Password admin01 Link ID Link name Encryption None Ethernet configuration auto SNMP R/O community public SNMP R/O user public SNMP R/O password password Quick Setup Guide Step 1. Login in to the PTP unit web management. To access the PTP unit Web management interface, configure your PC with a static IP address on the 192.168.2.0 subnet with mask 255.255.255.0. Connect the PTP unit in to the same physical network as your PC. Open the Web browser and type the default IP address of the PTP unit https://192.168.2.66/ and the login page will be loaded. Enter default administrator login settings: Figure 5 – Login Page The default administrator login settings for PTP unit are: Login: admin Password: admin01 After successful administrator login you will see the main page of the PTP unit Web management interface. The PTP unit now is ready for configuration. Step 2. Specify the operation mode: Master or Slave.The difference in configuration of Master and Slave is that the frequency does not need to be specified for the Slave. The Slave scans the air and chooses the frequency automatically after finding the Master.

LigoWave Page 13 Figure 6 – Specify Unit's Operating Mode Step 3. Specify a Link ID.LinkIDmust be identical for each unit of the same link.For instructions on changing this setting refer to the Radiosection in the Web management chapter. Figure 7 – Specify PTP Link ID

LigoWave Page 14 Step 4. Set Frequency at which PTP link will operate on Master unit. Change Frequency applies only for Master units.The Slave unit will choose the frequency automatically after the Master unit will be found. For instructions on changing this setting refer to the Radiosection in the Web management chapter. Figure 8 – Specify Frequency Step 5. Set Channel width at which PTP link will operate. For instructions on changing this setting refer to thesection in the Web management chapter. Figure 98 – Specify Channel Width

LigoWave Page 15 Step 6. Set link encryption for secure data transfer between PTP units.The security settings (encryption and passphrase) must be the same on each side of the link otherwise the link will not establish. For instructions on changing this setting refer to theRadiosection in the Web management chapter. Figure 9 – Set the Encryption Step 7. Reduce Transmit Power before testing the units placed on a table. PTP units placed in short distance with high transmit power may not work or even damage the peer's radio’s receiver. Step 8. Change web management login password. This is strongly recommended for security reasons.For instructions on changing the administrator’s password refer to the corresponding sectionAdministrative Account. Figure 10 – Change Administrator's Password Step 9. Save configuration and Reboot the device.

LigoWave Page 16 Figure 11 – Save Configuration Step 10. Setup the second unit of the PTP link in the same way and check if configured units established a Link. Verify PTP Link Connection After the both units of the PTP Link are configured, verify the PTP link quality: Step 1. Connect to the unit’s web management interface. Step 2. Check the Signal Indicator bar located at the bottom of the web management interface: Figure 12 – Signal Indicator Bar

LigoWave Page 17 Step 3. Run the iperf tool (or use the Link Test) on server and client sides to verify the point-to-point connection:

LigoWave Page 18 Figure 13 – iperf Results (TCP)

LigoWave Page 19 Figure 14 – iperf Results (UDP) Step 4. If test results are meeting the requirement and are no configuration will be done Transmit power should be increased, before mounting PTP units outside. Note that if the distance between the units is short, do not set Transmit Power to the maximum value. Observe the Signal Indicator bar – if it is red, decrease the Transmit Power.

LigoWave Page 20 Align Antenna Avoid standing directly in front of an operating antenna while aligning. The PTP units are equipped with two signal strength feedback systems: antenna alignment tool on the Web management interface and antenna alignment tool on the OLED screen. Follow the steps to establish a radio link between the two PTP units and align the units for the best signal strength. Step 1. Ensure that power is supplied to both PTP link units. Step 2. Ensure normal operation of the unit: check the OLED screen or Status page on the Web management interface. Step 3. Run the Antenna Alignment tool on the selected interface (OLEDor Web management) and move the antenna in the horizontal and vertical planes until the maximum RSSI visible on the Antenna Alignment graph is achieved. Figure 15 – Antenna Alignment Tool on Web Management Interface Figure 16 – Antenna Alignment Tool on OLED For detailed instructions on Antenna Alignment tool, refer to the respective sections:  Web management – Antenna Alignment  OLED screen –OLED control Step 5. After the maximal RSSI is reached, tighten down the unit in the optimum position.

LigoWave Page 21 PTP products are designed to provide superior performance at long range distances. With a proprietary wireless driver that was written for the sole purpose of optimizing wireless point to point links, one can achieve much higher throughput, especially at longer links, than standards based products. General Operation This section provides information about concepts used in PTP unit’s Web management interface. Instant Changes Some of the PTP radio parameters do not require to reboot the device. These parameters are named as instant changes. Instant changes are useful for best performance parameters tuning. These parameters will take effect as soon as the Apply button is clicked. When best configuration is founded press Save button and reboot the device to make changes permanent. Otherwise all instant parameter changes will be lost during PTP unit reboot. Instant changes are on theRadiosection. System Warnings and Errors There are 3 types of system messages that must be noted: notifications, warnings and error messages. These messages appear at the bottom of the page and can be closed by clicking the sign. For example notification messages are displayed in brown color and contain information about configuration changes: Figure 17 – Notification Message (1) This message has an implemented Reboot button. Simply click this button and the PTP unit will be rebooted at once – there is no need to navigate into theMaintenance page for additional action to reboot the unit. Notification messages also are on Wireless page Instant changes. This message informs you about instant changes that were made: Figure 18 – Notification Message (2) Web Management

LigoWave Page 22 Warning messages are displayed in red and contain PTP unit’s system cautions: Figure 19 – Warning Message The PTP unit contains built in validation for configuration settings in the web management interface. If a user sets an incorrect value in the entry field, its frame turns red, and if the user tries to save such incorrect configuration, an error message appears at the end of the page: Figure 20 – Error Message Signal Indicator The PTP web management interface has a PTP link signal indicator. This indicator displays real-time signal level in dBm of the Local and Remote units. Figure 21 – PTP Signal Indicator

LigoWave Page 23 The color of the Signal indicator will change according to the signal level quality of the unit. The green color means excellent link quality while the red color of the indicator means that link quality is poor. The red circle beside full filled red indicator switches on immediately when the signal level becomes too high and overload is detected. Figure 22 – PTP Signal Indicator (too Strong Signal) This may happen on an incorrect link layout, for example, in the case when the TX power parameter in the PTP units is set to maximum but physically the units are too close to each other (e.g. testing units are placed on a table). The screenshot below displays Signal indicator if there is no PTP link established between PTP units: Figure 23 – PTP Signal Indicator (no Link Established)

Choose "auto" for automatic detection of link speed and duplex mode. Management VLAN ID – specify the management VLAN ID [2-4094].If a management VLAN is enabled, all traffic received by the device must by tagged with the management VLAN ID to access the network. All non-tagged traffic will be dropped, thus reducing the risk of unauthorized access. Restrict management to – select interfaces on which management access will be restricted.

LigoWave Page 32 Radio Use the Configuration | Radio menu to set up radio settings for the PTP link: Figure 34 – Radio Settings Operating mode – specify the operating mode of the local device to create PTP link [Master/Slave]. The device mode depends on the network topology.  Master – in this mode local device is the controlling PTP link unit.  Slave – in this mode local device connects to the Master unit. Instant Changes Applying parameters in the Instant changes section does not require device reboot, therefore making easy parameters adjustment for best performance. Link ID – specify known network name of the remote device to establish a PTP link. Both sides (Master and Slave units) of the link must have the same Link ID name. Frequency – specify frequency at which the PTP link will be operating. If the device is operating in Slave mode, it will not have the possibility to choose a frequency. The Slave scans the air and connects to the Master automatically. Channel width – choose the channel width in MHz [20/40].

LigoWave Page 33 Both sides (Master and Slave) of a link must have the same Link ID, Channel width and Encryption specified. Encryption – select the security level for the PTP link:  None – means no security on link.  AES – means encryption with passphrase. Passphrase – specify passphrase of the AES security [8-63 characters]. This parameter appears and is mandatory when AES security is chosen. Transmit power – set the radio transmit power at which the device will transmit data. The larger the distance, the higher transmit power is required. To set transmit power level use the slider or enter the value manually. The transmit power level that is actually used is limited to the maximum value allowed by FCC regulatory agency. Multipath protection –if checked the signal will became more robust to signal interference caused by signal echos or reflections. However as the drawback the enabled multipath protection will lead to reduced link capacity. Mode – choose the PTP antenna operating mode: SISO – single input single output. The device will use only one antenna for data transfer. The antenna will be chosen automatically. MIMO – multiple input multiple output. The device will use two antennas for data transfer (two simultaneous streams). In this mode the *link capacity doubles *if compared to SISO mode. Data rate – select the device data transmission rates in Mbps from the drop-down list. ACK Timeout – specify the Acknowledgement timeout either in distance, or in time expression: Distance – specify the distance between PTP units, and ACK timeout will be calculated automatically according the indicated distance in kilometers or myles.

Click the Upgrade button: Figure 47 – Firmware Upgrade Upgrade – upgrade device with the uploaded image and reboot the system. Do not switch off and do not disconnect the device from the power supply during the firmware update process as the device could be damaged.

LigoWave Page 43 Tools Use the Tools menu to use the following device applications:  Site survey – to view the list of wireless networks in the surrounding area.  Antenna alignment – to align device antenna.  Link test – to check quality of the established PTP link. Antenna Alignment The antenna alignment test measures signal quality between the Master and Slave units. For best results during the antenna alignment test, turn off all wireless networking devices within range of the device except the device(s) with which you are trying to align the antenna. Watch the constantly updated display in the antenna alignment test window as you adjust the antenna. The Antenna Alignment test results appear when you click the Start button and finishes when you click the Stop button. Figure 48 – Antenna Alignment Tool Average – if this option selected, the graph will display the average RSSI of both antennas. Site Survey The Site Survey test shows overview information for wireless networks in a local geographic area. Using this test, an administrator can scan for working access points, check their operating frequency, encryption, see signal/noise levels and view whether device has enabled W-Jet or not. This feature may be used by the administrator find unused wireless channel so that PTP unit would not interference with adjacent working devices thus getting best possible performance. Note that Site Survey function can take several minutes to perform. To perform the Site Survey test, click the Start scan button:

LigoWave Page 44 Figure 49 – Site Survey Tool Start scan – click to perform the Site Survey test. Show only W-Jet AP – select this option to sort Site Survey results. Link Test We recommend to ensure that there is no traffic on the link before running the Link Test as results may not be completely accurate. Use the Link test tool to check the quality of the established PTP link. This tool tests the throughput at selected packet sizes and iterations. Link test can be run from either the Remote unit or Local unit. Results represent the maximum, minimum and average value of the performed test.

LigoWave Page 45 Figure 50 – Link Test Tool Iterations – specify number of test iterations. Packet sizes – specify packet sizes in bytes at which the test will be performed. Start – click to start the throughput test. Stop – click to stop the throughput test.

When the Logout button is clicked, the administrator is redirected to the login page of the PTP unit.

LigoWave Page 47 A) Run PTP Link in Small Distance Follow up the steps to run the PTP link for testing it in small distances (e.g. testing on a table) and achieve throughput up to 70 Mbps. Step 1. Power-up both units: Master and Slave. Step 2. PTP units must be placed at least a distance of 2 meters from each other. Step 3. Change major Radio parameters for both units (Master and Slave): Figure 52 – Radio Settings  Channel width: 40 MHz  Transmit power:5dBm  Multipath protection:off  Mode:MIMO 2x2 Appendix

LigoWave Page 48  Data rate: 300 Mbps  ACK timeout:Distance 0 km/miles Click Apply button for configuration to take effect. Step 4. Observe theSignal Indicatorbarat the bottom of the screen. If it is green the quality of the link is excellent whereas the red color indicates a poor quality of the link. If results do not meet the requirements increase or decrease the Transmit Power on Radio page depending on the status of the Signal Indicator bar. TheSignal must be approximately 25-30dBm. Step 5. Start the testing: start the iperfserver , then iperf client: Figure 53 – iperf Results (TCP)

LigoWave Page 49 Figure 54 – iperf Results (UDP) Step 6. If the result meets the requirements, before mounting PTP units outside, increase the Transmit Power.

LigoWave Page 50 B) Resetting Unit to Factory Defaults PTP units have the capability of being reset to defaults by pinging the device with a certain packet size when the radio is booting. During the startup of the device, when the drivers of the ethernet interfaces are loaded, the discovery daemon is started. The daemon suspends startup process for 3 seconds and waits for ICMP "echo request" packet of length 369 bytes. If the packet received, the discoveryd resets the device to default configuration. It is recommended to connect PC to the device via switch, as depending on PC OS settings, the ARP table might be flushed during wired link status change (connecting the device that will be reset). Steps to reset to default settings: Step 1. Power off the device. Step 2. Obtain the device MAC address. Step 3. Connect a PC to the same physical subnet as the device. Step 4. Execute 'arp -s' command to assign the IP address (IP address should be from the same subnet as PC) to the device MAC address: arp -s <IP address to assign><device MAC address> Note that syntax of MAC address differs depending on OS:  Linux OS: AA:BB:CC:DD:EE:FF  Windows OS: AA-BB-CC-DD-EE-FF Step 5. Start pinging the device: For Linux users: ping <IP address>-s 369 For Windows users: ping <IP address>-l 369 -t -w 0.2 Step 6. Power up device and wait about 30sec or more (depending on device hardware). Step 7. Stop pinging the device, and let the device boot as usual. The device should start up with factory default settings.
