As a general rule on any monopole installations the TX antenna shall be attached to a 6 foot side arm mount, minimum distance away from the monopole unless the antenna extends above the monopole in its entirety. Likewise the antenna shall be kept a minimum distance of 6 feet from any other vertical structures on other types of towers. For roof tip installations, the TX antenna must extend above all parapet walls and penthouses on the roof top. This radio transmitter (FCC ID: A4P-100-0007-01) has been approved by FCC to operate with the antenna types listed below with the maximum permissible gain and required antenna impedance for each antenna type indicated. Antenna types not included in this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited for use with this device. This radio transmitter may only operate using a vertically polarized antenna with maximum gain of +8 dBi. To reduce potential radio interference to other users, the antenna gain should be so chosen that the equivalent effective radiated power (ERP) does not exceed 30 Watts. Antenna Type: Monopole Polarization: Vertical Maximum Gain: +8 dBi (maximum gain of antenna + cable loss is 3dBd) A CSV file (configuration file) per transmitter is created by the NOC engineer, based on the installation parameters such as line lengths, antenna type etc. The TX output power level setting is contained in the CSV file. The output power is adjusted by the “attenuation” setting. This value in the CSV file is calculated by a formula to set the output power (not to exceed 30W EIRP). The variables used in the calculation include PA Gain (Gpa), TX Antenna Gain (Gant), TX filter insertion loss (ILflt), internal cable loss (ILint), external cable loss (ILext), and transceiver output power (PTCVR). EIRP (W) = 10^((PTCVR •] ILint + Gpa •] ILflt •] ILext + Gant) / 10) / 1000 Confidential Page 19 Page 19 11-Sep-12 of 30 Document Name: WAPS BEACON Installation Manual Version No: 1.4 Company Name: NextNav, LLC. 3.5 Connecting to the Power System 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12.

Flip Battery switch to the “ON” position b. Flip the Main Switch from step 4 to the OFF position. c. Verify all LEDs from step 7 are lit. d. Flip the Main switch back to the ON position. Connect the EvDO antenna cables to the EvDO Tx port. In cases of sites which have been documented as requiring EvDO diversity, connect the diversity antenna to the EvDO DIV port. In cases of sites which have been documented as needing a POTS line, connect the phone line to the ‘TELCO’ port. Connect the field service laptop with an Ethernet cable to the ‘Ethernet’ port on in the Phoenix switch port #5. Wait for a few seconds to get an IP address on the field service laptop. Try and browse the internet to ensure connectivity. Once connectivity is ensured, call the operator at the NOC to further commission the beacon box.

Usage Model 4.1 Hardware Connections for the Server The socket server expects the following modules to be connected to the Zeus board PA module GPS Module Rubidium Weatherboard Socket clients communicate with the Socket Server running on zeus over the Ethernet link as shown in figure below. For developmental purposes, multiple zeus setups can be connected to the network as long as they have DHCP addresses. One computer on the same network can be used to communicate with multiple Zeus systems using the IPAddress:Port configuration. Router Ethernet Switch Zeus1 DHCP Zeus2 DHCP Zeus3 DHCP GUIClient Computer 4.2 Socket Server Startup The socket server runs on the Zeus Board ARM Linux Kernel. To connect to the Zeus Board, use an ssh client such as ‘putty’ from the GuiClient computer. Confidential Page 21 Page 21 11-Sep-12 of 30 Document Name: WAPS BEACON Installation Manual Version No: 1.4 Company Name: NextNav, LLC. 1. Login to the Zeus ARM Linux shell using the ssh client 2. Verify that the socket server is not already running 3. pgrep -fl Main.py # This command will show if the server is already running. If not continue with the next steps 4. cd ~/apps/server 5. python Main.py –s /dev/ttyO1 > /tmp/Main.log & 4.3 Socket Client Installation The socket client should be installed on the GuiClient computer. This machine can be a Windows or a Linux PC (with X Windows) as long as python and svn are installed on the machine. 1. Download pythonxy from http://code.google.com/p/pythonxy/, full version (2.7.2.1). During installation, make sure that PySerial is selected. 2. Download the Tortoise SVN client http://tortoisesvn.net/downloads.html (optional) 3. Unzip the client.zip zipfile on the GuiClient computer and change directory to the ‘client’ folder. 4.4 Socket Client Startup 1. On the client computer, start the ‘GUIClient.py’ script by double clicking on the program. (or ‘python GUIClient.py’ in the case of Linux) 2. The above step will launch a window as shown in Figure 13. In the ‘Summary’ tab, enter the IP of the beacon provided by the field technician and port number as ‘7734’. 3. Clicking on connect establishes a TCP/IP connection with the beacon and the connect button changes to ‘Disconnect’ confirming a successful connection. 4. If step 4 fails and an error message ‘Could not connect to server’ is displayed then debug for one of the following causes: a) An error in IP/ port entered. b) Ethernet connection issues. c) The socket server script not running on the zeus platform.
