FCC Warning CE Mark Warning This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
IC Notice Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.

Introduction The FreeMile 5.8GHz MIMO 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 interface and the Remote unit is the one which is connected to the Local unit in FreeMile 5.8GHz MIMO link.
Application Examples Building to Building Connectivity Use the FreeMile FODU 5.8GHz 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 FreeMile FODU 5.

Power on LED Ethernet + Power (RJ45) Figure 6 – FreeMile 5.8GHz MIMO front panel Accessing the FreeMile 5.8GHz MIMO Unit’s Web Management In order to access the FreeMile 5.8GHz MIMO unit and to perform initial configuration you will need a laptop with LAN card, 2 Category 5e Ethernet cables and a Power over Ethernet injector.
Quick Setup Guide Step 1. Login in to the FreeMile 5.8GHz MIMO unit web management. To access the FreeMile 5.8GHz MIMO 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 FreeMile 5.8GHz MIMO unit in to the same physical network as your PC. Open the Web browser and type the default IP address of the unit https://192.168.2.66/ and the login page will be loaded.
Figure 9 – Specify FreeMile 5.8GHz MIMO Link ID Step 4. Choose the Country in which the link will operate. FreeMile 5.8GHz MIMO unit will automatically adjust Radio settings to meet country/region specific regulations. Figure 10 – Specify Country Step 5. Set Frequency at which 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.
Figure 11 – Specify Frequency Step 6. Set Channel width at which link will operate. For instructions on changing this setting refer to the Error! Reference source not found. section in the Web management chapter. Figure 12 – Specify Channel Width Step 7. Set link encryption for secure data transfer between FreeMile 5.8GHz MIMO units. The security settings (encryption and passphrase) must be the same on each side of the link otherwise the link will not establish.
Figure 13 – Set the Encryption Step 8. Reduce Transmit Power before testing the units placed on a table. FreeMile 5.8GHz MIMO units placed in short distance with high transmit power may not work or even damage the peer's radio’s receiver. Step 9. Change web management login password. This is strongly recommended for security reasons. For instructions on changing the administrator’s password refer to the corresponding section Administrative Account. Figure 14 – Change Administrator's Password Step 10.
Figure 15 – Signal Indicator Bar Step 3. Run the iperf tool (or use the Link Test) on server and client sides to verify the point‐to‐point connection: Figure 16 – iperf Results (TCP) SAF FreeMile 5.8GHz FODU User Guide • Rev. 1.0 • Software version 6.
Figure 17 – 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 FreeMile 5.8GHz MIMO 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.

FreeMile 5.8GHz MIMO Link Establishment This chapter provides instructions how to install a Point to Point link. A Point to Point link operates in pairs of two units with the same configuration. Both units must be installed, and the antennas aligned for maximum throughput. Mounting the FreeMile 5.8GHz MIMO Unit The FreeMile 5.8GHz MIMO unit’s mounting bracket is designed to make installation on a pipe easy. The unit is attached and it's position is fixed with bolts. Figure 18 – Attaching SAF FreeMile 5.
Assembling FreeMile 5.8GHz MIMO Ethernet cable connector Figure 19 – Assembling Ethernet weatherproof connector Fig. 19(1). Put rubber sealing inside the connector as shown. Fastening screw should be placed on the front part of connector. Fig. 19(2). Put connector parts on the cable. Fig. 19(3). Stick the rubber gasket on the connector. Fig. 19(4). Plug RJ45 connector into the Ethernet socket. Fig. 19(5). Fix the connector to the socket with screw.
Antenna Alignment Avoid standing directly in front of an operating antenna while aligning. The antenna alignment procedure can be made easier by placing one person at each antenna location during alignment process. However, alignment should be performed on one antenna at a time, each person alternatively turns antenna until the RSL is optimized. The following steps are required to properly align the antennas: 1.
Web Management FreeMile 5.8GHz MIMO 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.

Appendix A) Run FreeMile 5.8GHz MIMO Link in Small Distance Follow up the steps to run the 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. FreeMile 5.8GHz MIMO units must be placed at least a distance of 2 meters from each other. Step 3.
Step 4. Observe the Signal Indicator bar at 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. The Signal must be approximately 25‐30dBm. Step 5. Start the testing: start the iperf server , then iperf client: Figure 57 – iperf Results (TCP) SAF FreeMile 5.
Figure 58 – iperf Results (UDP) Step 6. If the result meets the requirements, before mounting FreeMile 5.8GHz MIMO units outside, increase the Transmit Power. SAF FreeMile 5.8GHz FODU User Guide • Rev. 1.0 • Software version 6.
B) Resetting Unit to Factory Defaults FreeMile 5.8GHz MIMO 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.
