StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 6 1. General Safety Information The information that follows, together with local site regulations, should be studied by personnel concerned with the operation or maintenance of the equipment, to ensure awareness of potential hazards. Switch off supplies before removing covers or disconnecting any RF cables, and before inspecting damaged cables or antennas. Avoid standing in front of high gain antennas (such as a dish) and never look into the open end of a waveguide or cable where strong RF power may be present. Users are strongly recommended to return any equipment that requires RF servicing to Silvus Technologies. CAUTION: This system contains MOS devices. Electro-Static Discharge (ESD) precautions should be employed to prevent accidental damage.

StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 7 1.1 Health & Safety Exposure to Non-Ionizing (RF) Radiation/Safe Working Distances The safe working distance from a transmitting antenna may be calculated from the relationship: D = √𝑃𝑇 ∙ 𝐺𝑅4𝜋 ∙ 𝑤 In which D = safe working distance (meters) PT = transmitter or combiner power output (watts) GR = antenna gain ratio = anti log (gain dBi ÷10) w = power density (watts/square meter) The RF power density value is determined by reference to safety guidelines for exposure of the human body to non-ionizing radiation. It is important to note that the guidelines adopted differ throughout the world and are from time-to-time re-issued with revised guidelines. For Silvus use, a maximum power density limit of 1w/m² is to be applied when calculating minimum safe working distances. Important Note: It must be remembered that any transmitting equipment radiating power at frequencies of 100 KHz and higher, has the potential to produce thermal and a-thermal effects upon the human body. To be safe: a) Operators should not stand or walk in front of any high gain antenna such as dish antennas, nor should they allow anyone else to do so. b) Operators should not operate any RF transmitter or power amplifier with any of its covers removed, nor should they allow anyone else to do so.

StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 8 1.2 Maximum RF Power Density Limits The RF Radiation Power Density limit figure recommended by Silvus is based upon guideline levels published in: a. IEEE standard C95.1 1999 - IEEE Standard for Safety Levels with respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz. b. Guidelines for Limiting Exposure to Time-varying Electric, Magnetic & Electromagnetic Fields (up to 300 GHz) published in 1998 by the Secretariat of the International Commission on Non-Ionizing Radiation Protection (ICNIRP). Both documents define guideline RF power density limits for "Controlled" and "Uncontrolled" environments. An uncontrolled environment is defined as one in which the person subjected to the RF radiation may be unaware of and has no control over the radiation energy received. The uncontrolled environment conditions can arise, even in the best regulated operations and for this reason the limits defined for the uncontrolled environment have been assumed for the RF Central recommended limit. Documents a) and b) also show the RF power density guidelines to be frequency dependent. Different power density / frequency characteristics are presented in the two documents. To avoid complexity and to avoid areas of uncertainty, Silvus recommends the use of a single power density limit across the frequency range 100 kHz to 300 GHz. The 1w/m² power density limit we recommend satisfies the most stringent of the guidelines published to date.

StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 9 2. Introduction The StreamCaster family of MIMO radios was designed with operator ease of use in mind. Each radio is capable of operating in a multitude of configurations that are accessed via simple web pages within the radio. Settings such as transmit power, frequency, channel bandwidth, link adaptation and range control can be accessed by simply using a web browser to log into any radio within the network. This quick start user guide contains all essential information for the user to configure the StreamCaster radio and to also run an iperf network test. 3. StreamCaster Network Each StreamCaster MIMO radio has a fixed static IP address in the 172.20.xx.yy network. The radio operates as a network switch; the user equipment does not need to be on the same subnet as the radio during operation. It is possible to setup a secondary IP address on the radio if the user finds this feature convenient. Setting up a secondary IP address is useful if the user wishes to access the radio’s web interface in their network.

StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 37 5. Web Interface 5.1 Getting Started Connect a laptop to the StreamCaster radio using the supplied Ethernet cable and turn on the radio. Users can type “ping <IPaddress>” in order to determine whether the radio is fully booted. A web configuration will then be available by typing the radio IP address in a web browser. Please ensure that your laptop is on the same subnet as the radio (172.20.xx.xx by default). Users will be directed to the Basic Configuration page. (See Figure 16) 5.1.1 Basic Configuration Figure 16 Basic Configuration Page This page is used to set basic configurations. A brief description of each parameter is given below.  Frequency: This defines the frequency of the signal. There is a drop-down menu for frequency selection. The frequency choices will vary depending on the StreamCaster model(s) you are using. Please see Section 7 for “Custom Frequency Plan” access and installation instructions.

StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 38  Bandwidth: This defines the RF bandwidth of the signal.  Network ID: Network ID allows for clusters of radios to operate in the same channel, but remain independent. A radio with a given Network ID will only communicate with other radios with the same Network ID.  Link Distance: Set to an approximate maximum distance between any two nodes in meters, e.g., 5000 for 5km (default). It is important to set the link distance to allow enough time for packets to propagate over the air. Failing to set the link distance to an approximate maximum distance can result in over the air collisions and a degradation of performance. It is recommended to set the link distance 10-15% greater than the actual maximum distance.  Total Transmit Power: This defines the total power of the signal (power is divided equally between the radio antenna ports). There is also an option to ‘Enable Max Power’ which will allow the radio to push to the highest TX power it can support. This will be slightly different on each radio and can be up to 2 watts total.  Wired Backbone Gateway: This setting pertains to wired backbone functionality (See Section 6: Wired Backbone). For normal operation, set Wired Backbone Gateway to enable. If multiple radios will be connected to a wired backbone, only one radio should be enabled as a Wired Backbone Gateway and all others on the wireline should be disabled.  Routing Beacons on Ethernet Port: For radios to be able to communicate and transfer data over a wired link, routing information needs to be sent over the wireline. These packets are broadcast packets that are sent even if there is only one radio on the network. If wired backbone is not being utilized, the user can disable these routing beacons to prevent loading their local network with these routing packets.  Apply: Apply the new values. Values will change back to the default setting after reboot.  Save and Apply: Apply the new values and set the new values as the default.

StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 39 5.1.2 Advanced Configuration Figure 17 Advanced Configuration Page This page is used to set the advanced settings. A brief description of each parameter is given below. MAC Settings:  Routing Beacon Period: Controls how often routing beacons are sent to other radios. A lower Routing Beacon Period results in faster reaction to topology changes. A lower Routing Beacon Period also adds more overhead to the network which scales with the number of nodes in the network. For larger networks, a larger Routing Beacon Period is recommended. Default value is 100ms.  Routing Beacon MCS: Select the MCS that routing beacons are sent at. Higher MCS values require less network overhead and may be beneficial for larger networks. The

StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 40 drawback is that the link will break when the Routing Beacon MCS can no longer be supported.  Fragmentation Threshold: Allows user to determine the minimum over-the-air packet size in bytes. Smaller packet size can improve performance in high mobility while a larger packet size will allow for more throughput. (1600 bytes default).  Maximum Ground Speed: This setting improves performance in high mobility scenarios where the wireless channel may change rapidly. Setting this value to an unnecessarily high value may have an impact as high as 25 percent on overall achievable throughput.  Burst Time: The burst time determines the maximum amount of time each node is allowed to transmit at once. A larger burst time will provide higher throughput at the cost of higher latency. On the other hand, a smaller burst time will provide less latency at the cost of less throughput. The throughput values shown in Table 14 and Table 16 assume the minimum burst time.  RTS Retries: A node wishing to send data initiates the process by sending a request to send message (RTS). The destination node replies with a clear to send (CTS) message. Any other node that receives the RTS or CTS message will refrain from sending data for a given time. In larger networks, there is a higher probability of collisions occurring when an RTS is sent out. This field defines the number of retries before a packet is dropped. A lower value will result in faster handoffs in mobile situations.  Number of Retransmissions: Allows the user to define the number of times a lost packet is retransmitted before being dropped. Default value is 20.  MCS: Choose the modulation and coding scheme (MCS). If this is set as AUTO, the radio will dynamically cycle between a subset of the modes depending on the quality of the link. This is the recommended setting for most users and will provide the maximum data rate that the link can support. The EXTENDED AUTO mode includes 64QAM rate modes on top of those included in the AUTO mode. Table 14 and Table 16 below show the estimated UDP data rate and sensitivity for each MCS. This table assumes a 20MHz bandwidth, 1000 meter link distance and 1600 byte fragmentation threshold.  Transmit Channels: Allows user to Enable or Disable each channel on the radio for TX.  Receiver Channels: Allows user to Enable or Disable each channel on the radio for RX.  Beamforming (SC4200 Only): Enable or disable TX Beamforming (Up to 40% increase in range when enabled)  Radio Mode: Switch between Network mode and PHY Diagnostics. If the value equals 0, it is in Network mode; if the value equals 1, it is in PHY Diagnostics. PHY Diagnostics mode is only relevant for users who wish to run diagnostic tests on the radio.

StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 44 Network Settings:  Virtual IP: Enable or Disable the Secondary IP address for the radio.  Virtual IP Address: Set the secondary IP address for the radio. The user may set this to be on the user’s IP network, e.g., 192.168.2.10. Once this secondary IP address is set, the user may access the radio web page using either the native IP address or the secondary IP address. Please note that the secondary IP address should NOT be on the 172.20.xx.xx subnet.  Virtual Netmask: Netmask for the Secondary IP address, e.g. 255.255.255.0.  Gateway: Gateway for local network to allow radio to connect to the internet  VPN: For WAN wired backbone scenarios where radios from two different sites are connected via the internet, a public N2N server is needed to route the data. Here is an example of how to setup an N2N server on a server hosted by Amazon AWS running Ubuntu 12.04: Compile: git clone https://github.com/lukablurr/n2n_v2_fork ### downloads the code cd n2n_v2_fork export N2N_OPTION_AES=no make clean make Execute: ./supernode -l 9000 -v Server will be running on port 9000.  VPN Server IP: IP Address of N2N VPN Server  VPN Server Port: Port that the N2N VPN server is configured to listen on. VLAN Settings (License Enabled Feature): VLANs allow users to segregate the Ethernet layer by assigning one or more VLAN IDs to the ports of a VLAN switch. Ethernet packets are only allowed to travel between ports that belong to the same VLAN. To allow concatenating multiple VLAN switches and/or a single physical interface residing on multiple VLANs, a VLAN ID can be inserted to the Ethernet packet header to indicate which VLAN the packet belongs to. This is called VLAN Tagging. A packet that contains a VLAN ID is called a tagged packet. A port on a VLAN switch typically operates in either access mode or trunk mode.  VLAN Mode: Specify ‘Access’ or ‘Trunk’ mode for the radio per the 802.1Q standard.

StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 45  Default (Native/PVID) VLAN: This is the VLAN associated with untagged packets entering the radio. The virtual IP of the radio is available on this VLAN.  Management VLAN: This is the VLAN used for radio management (e.g. routing and network management). All radios on the network should have the same management VLAN. The 172.20.xx.yy IP of the radio is available only on this VLAN.  Trunk VLAN(s): This setting enables the trunking of VLANs when the radio is connected to an 802.1Q switch. If left empty, only the native and management VLAN traffic will be allowed. User may enter a comma separated list of VLANS, e.g. 4,5,6 or an arry of VLANs in the format of a:b:c where a and c are start and end, and b is step size, e.g. 4:1:7 translates to 4,5,6,7. Any combination of the above is allowed. WiFi Settings (License Enabled Feature – SC3822 Only): Note: Use of this feature requires a Silvus USB-WiFi adapter. The WiFi settings will only display if the USB WiFi license is loaded, and the WiFi dongle is attached to the radio’s USB port before it is powered on.  Wifi Mode: Choose between AP, Client or Disabled. AP mode turns the WiFi dongle into a wireless AP. This mode is useful for connecting phones, tablets, laptops, etc. to the radio in order to pull up the web interface and access other devices in the mesh network. Client mode allows the radio to connect to another wireless AP. This mode is useful for connecting to wireless cameras and other devices which generate their own ‘hotspot’. Once set to client mode, a list of detected wireless networks will be displayed with an option to connect.  Mode: When set to AP, the wireless can be configured to be in Bridge Mode or NAT mode. In Bridge mode, the wireless interface is bridged with the Ethernet interface and the rest of the mesh. This is the simplest mode as all data is transparent and at layer 2. NAT mode puts the WiFi wireless traffic on a LAN, and the rest of the Silvus mesh network on a WAN. In effect, this means that a device connected wirelessly via the NAT AP will be able to find any device in the larger mesh network, but not vice versa. NAT mode is recommended for more advanced users who wish to be able to segregate data.  SSID: Define the SSID for the wireless network. Must be between 1-31 characters. User also has the option to prevent the AP from broadcasting it’s SSID by checking the ‘Hide’ box.  Security Mode: Determines whether the AP requires a password to connect.  Password: If ‘Security Mode’ is set to ‘Secure’, a password between 8 and 63 characters must be set.

StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 46  Wifi Channel: The Silvus USB-Wifi adapter supports 20 different Wifi channels in both the 2.4GHz and 5GHz frequency ranges. It is recommended to set the Wifi channel to a frequency that has maximum separation from the mesh network frequency. (i.e. if mesh network is operating at 2.4GHz, it is recommended to set the Wifi frequency somewhere in the 5GHz range). Note that not all user devices support 5GHz Wifi.  Wifi Standard: Specify 802.11b or g wifi standard. Some legacy devices may not be able to connect to an 802.11g network.  DHCP: When enabled, the USB-Wifi adapter will assign IP addresses to connected devices. Note that when the AP is set to ‘Bridge’ mode, the DHCP will be delivered to the entire mesh. Users should be careful to make sure there is only one DHCP server connected into the mesh network to avoid any conflicts. When DHCP is enabled, the DHCP parameters must be set.  Wifi TX Power: This slider can be used to control the Wifi TX power from 0dBm (1mW) up to 17dBm (50mW).  Wifi Status: Provides status information of the wifi adapter. A list of connected clients will also be shown here.  Port Forwarding (NAT Mode Only): When in NAT mode, devices on the larger mesh will not be able to locate devices connected to the wireless adapter. This can be overcome by mapping port forwarding for specific data streams.  Apply: Applies the new values but does not save them to flash.  Save and Apply: Save the new values to flash and apply.

StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 47 5.1.4 Quality of Service (QoS) # Qo S Figure 19 Quality of Service (QoS) Configuration Page Quality of Service Port Classification: The Quality of Service configuration page allows the user to make a distinction between low and high priority traffic transmitted through each radio. High priority traffic will always jump to the front of the queue and bypass any awaiting low priority traffic. In instances where the link cannot support the amount of data trying to be transmitted, low priority traffic may be completely shelved in order to ensure that the high priority traffic gets through. To specify Low/High priority traffic, the user needs to simply input the port number that the traffic will be arriving on. Multiple ports of the same priority can be separated by a comma (i.e. 5001, 6001, 6002). Alternatively, the user can specify a range of ports using a dash (i.e. 5001-5006). Any combination of commas and dashes will work as well (i.e. 5001, 6001-6007, 8000). Any field can be cleared by removing the text and clicking ‘Apply’ or ‘Save and Apply’. If unspecified, traffic is treated as Low Priority.

StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 48 Quality of Service Contention Window Control: The Quality of Service Contention Window Control tunes the aggressiveness of CSMA backoffs when collisions occur. The MAC takes random backoffs in the range [0, 2^cw_min]. Every time there is a collision/noise it will increase this cw_min by 1, until it is capped by cw_max. E.g. 4,10 translates to random backoffs in the range [0,16] in the beginning for a packet. If the first try results in a collision, it will pick another backoff in the range [0,32], then [0,64], until [0,1024]. After successful transmission, backoff is reset to [0,16]. The default is 4,10 for low priority, and 3,6 for high priority. For larger networks, it is recommended to increase the Low Priority minimum to reduce the chance of collisions occurring. End-to-End Automatic Repeat request (Beta Feature – License Enabled) The End-to-End ARQ feature provides packet re-ordering capability to the radio. This feature is useful in applications that are sensitive to out of order packets (i.e. video applications where the decoder does not have the ability to re-order packets). To enable packet reordering, specify the port number of the subject data in the same format as the QoS ports on the source and destination radio. The settings should match on both radios and do not need to be set on any relays. Retransmissions Disabled – Only packet re-ordering with no end-to-end retransmissions if packets are lost. The receiver timeout is the length of time the receiver waits for out-of-order packets before giving up and delivering the data it has in its buffer. This is similar in concept to the jitter buffer in common video decoders (e.g. VLC). The worst case end-to-end delay will be incremented by the receiver timeout value. Retransmissions Enabled – Packet re-ordering and end-to-end retransmissions enabled in case of packet loss. The retransmission timeout is the time the transmitter will wait before re-sending a lost packet. The worst case end-to-end delay will be incremented by the retransmission timeout value. Determining Timeout Value – Both receiver timeout and retransmission timeout should be set to roughly 3 times the end-to-end latency. The end-to-end latency can be found by disabling e2e and doing a ping between the transmitter and receiver.

StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 49 5.1.5 Serial/USB Setup Figure 20 Serial/USB Setup Configuration Page Serial Port Setup: Each StreamCaster is equipped with one user configurable serial port. A special power cable and null modem cable are required for access to the radio’s serial port. A brief description of each parameter is given below.  Serial Port Mode: The user can select one of four available modes for the serial port: GPS, RS232, Debug, and Disabled. o GPS: In GPS mode, an external serial GPS module can be connected to and powered from the serial port of the radio. A gpsd service daemon running on the node will make the GPS information available to any user on the network from TCP/IP port 2947. For more information on gpsd please see: http://catb.org/gpsd/ In addition, GPS information can be pushed to the radio via the Ethernet port or pulled by the radio from a remote device such as an SC-IOM. If using an SC-IOM to obtain GPS, set the GPS mode to remote, the GPS Server IP to the IP address of the SC-IOM, and the Port to 2947.

StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 50 o RS-232: The RS-232 mode provides a wireless serial connection between any two serial devices connected to StreamCaster nodes on the network. In this mode, the user must configure the RS-232 protocol parameters shown in Figure 20 above. The transport protocol for the serial data can be set as either TCP or UDP. For data that is sensitive to latency such as command and control data, UDP is recommended. For data that cannot tolerate any data loss, such as telemetry data, TCP is recommended.  The Peer IP can be the native or virtual IP address, but must be same at both ends.  Baud rate must match the baud rate of data being sent.  Note! – An additional ‘null modem’ cable may be needed at either end, depending upon whether connected device is acting as a terminal or as a control (DTE or DCE) o Debug: The debug mode is used to gain terminal access to the StreamCaster radio and is available for debug or interface purposes (API commands). The user’s terminal client should be set to a baud rate of 115200 for console access to the radio. o Disabled: This mode completely disables the serial terminal of the radio.  Apply: Apply the new values but does not save them to flash.  Save and Apply: Save the new values to flash and apply. USB Status (3822/4200): The USB port on the 3822/4200 can auto-detect whether the connected device is a USB host or client device. The USB cable should not be unplugged while the radio is running.

StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 51 5.1.6 Node Diagnostics Figure 21 Node Diagnostics Configuration Page The Node Diagnostics page allows the user to specify an IP and Port number for Temperature and RSSI (Receiver Signal Strength Indication) reports to be delivered to. This is useful for users that intend to feed this information into some other platform for analysis and recording. Section 7 gives more information on the format of streaming reports. Temperature Thresholds: In addition to receiving temperature reports, this page can be used to set minimum and maximum temperature thresholds for the radio. The StreamCaster™ family of radios is equipped with on board temperature sensors which are monitored to prevent overheating. Once a radio reaches the maximum temperature threshold, the radio will begin to reduce its transmission time until the temperature falls below the minimum temperature threshold. By default, the min and max values are 75C and 85C respectively. LED Configuration: This setting allows the user to disable or enable the LED on the faceplate of the radio. Voltage Monitor: Radios built on or after Jan 1, 2015 have the ability to monitor the input voltage, displayed here.

StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 52 5.1.7 BDA Support Figure 22 BDA (Bi-Directional Amplifier) Support Configuration Page The BDA Support page is used to configure the radio to work with an external bi-directional amplifier. These settings should be configured before connecting the amplifier to the radio.  Auto Noise Estimation: When enabled, the radio can automatically estimate the noise in the channel, including any amplification due to the external amplifier. It is preferred that this remain disabled and the LNA gain values be manually input further below, but if the LNA gain values are not known, this can be used instead.  PA Mode: Either set to “No PA” when there is no amplifier present or “Basic Mode” when using an external amplifier. Basic Settings:  PA Gains for Channels 1-4: Enter the gain (dB) for the power amplifier connected to each channel of the radio.  LNA Gains for Channels 1-4: Enter the gain (dB) for the LNA connected to each channel of the radio.  Maximum PA Output Power Per Channel (dBm): Enter the maximum output power for each PA.  Apply: Apply the new values but does not save them to flash.  Save and Apply: Save the new values to flash and apply.

StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 57 5.1.10 PTT (SC4200 Only) Figure 29 PTT (Push-to-Talk) The PTT page can be used to configure talk groups (Multicast Groups) and speaker/mic settings for PTT enabled radios. Radios can only communicate with other radios that are subscribed to the same ‘Multicast Group’. Currently a radio is permitted to be active in only one Multicast Group. Mic Type – Supported MIC types are Moving Coil or Condenser. The input amplification is adjusted based on the Mic Type chosen on this page Mic Bias Voltage – Options are 90% (3V) or 65% (2.15V). Audio Encoder Type – Default option is G.722 (high quality). G.711 is also supported for backwards compatibility with the SC-IOM Speaker Volume – Moving slider adjusts the gain on the speaker Mic Volume – Moving slider adjust the gain on the microphone

StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 58 5.1.11 Spectrum Scan (Beta Feature – License Enabled) Figure 30 Spectrum Scan Results The spectrum scan feature turns a Silvus network of radios into a distributed spectrum analyzer. When a scan is initiated, each selected radio in the network will go offline, perform a scan of the requested range, and report back. Figure 30 Spectrum Scan above shows the results from a scan of a network of 6 radios. The checkboxes at the top allow users to show or hide plots from specific radios. The three plots provided are: Average – Displays the average power over the time duration specified in the settings. Peak – Displays the peak power seen at any point during the scan for each frequency. This is the equivalent of the ‘Max Hold’ feature on common spectrum analyzers. Threshold – Displays the duty cycle of interference stronger than the user specified ‘Threshold’ power. In the example above, the threshold was set to 5dB. The plot is showing the percentage of time that the measured power is more than 5dB above the radio’s noise floor.

StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 59 Settings: Figure 31 Spectrum Scan Settings Clicking the settings button at the top left of the window will show the settings pane as shown in Figure 31 Spectrum Scan Settings The node list shows the list of nodes currently connected into the mesh network. Any nodes selected will be used as part of the spectrum scan. Nodes that are unchecked will resume normal operation. Note that an unchecked node will continue transmitting in the frequency channel it is operating in and its transmission will show up in the scan results of scanning radios. Mode – Set to Spectrum Scan or Zero Span. Spectrum Scan mode provides plots of signal strength over frequency. Zero Span provides a plot of power over time in a 20MHz Bandwidth (see Figure 33 Zero Span Results below. Spectrum Scan Mode: Center Frequency – Specify the center frequency of the scan. Span – Specify the span of the scan, centered on the center frequency. (e.g. Center freq of 2450MHz and span of 100MHz will scan 2400-2500MHz). A large span will take longer to complete. Antenna Mask – Choose which antenna on the radio to use for scanning. If there are 2 antenna radios in the network antenna 1 or 2 must be chosen. Resolution Bandwidth – Specify the RBW for the scan. A smaller RBW will provide a more detailed plot, but will take longer to complete the scan. 625KHz is a good balance between scan detail and time of scan.

StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 60 Threshold – Specify the threshold for measurement of the duty cycle of interference. Duration – Duration of each scan. A longer duration will provide better accuracy but will take longer to complete. Zero Span Mode: Figure 32 Zero Span Settings In the Zero Span mode, the radio will provide a plot of the power measured in a 20MHz bandwidth across time. Zero Span can only be conducted on one radio in the network at a time. Other radios in the network will continue to operate and transmit so a zero span scan should not be conducted within the same frequency that the mesh network is operating in. Center Frequency – Specify the center frequency of the scan. Sampling Rate – Set the sampling rate of the scan. (0.3Msps recommended) Antenna Mask – Choose which antenna on the radio to use for scanning. If there are 2 antenna radios in the network antenna 1 or 2 must be chosen. Duration – Duration of each scan. A longer duration will provide better accuracy but will take longer to complete.

Note that since the SC3500 and SC3800 do not have USB ports, you will not be able to set a password for the interface.

StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 64 5.2 StreamScape Network Manager Silvus’ StreamScape Network Management Utility was designed to monitor the status of a Silvus mesh network in real-time. The graphical interface network map, shown in Figure 1, allows users to quickly and effortlessly view the network topology and configure key parameters of the network. For ease of use, the Silvus StreamScape utility is designed to be accessible from a Firefox or Chrome web browser. 5.2.1 Network Topology Figure 37 Silvus StreamScapeNetwork Manager The network topology provides the user with real-time visual feedback of the network. Users will be able to determine several network characteristics at a glance with the following features:

StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 65  Color Coded Link Health – Color coding of each link in the network allows the user to quickly identify the weak links within a network. A link between two nodes will transition from green to yellow to red as the link weakens while also displaying the SNR of the link. This can be seen in Figure 38.  Route Health – The Silvus StreamScape Utility will alert the user when too many packets are being routed through a single node. In such cases, a node will change from green to yellow to red as the packet queue increases (see ‘node4411’ and ‘node4569’in Figure 38). This will allow the user to recognize the issue and rearrange the network accordingly. Figure 38 Example Network Topology  Routing Information – The user can view the routing path between any 2 nodes within a network by simply specifying the source and destination node in the Control Panel on the left hand side. The path will turn bold as shown in Figure 39 for the path from ‘node4411’ to ‘node4569’.

StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 66 Figure 39 Routing Path  Custom Node Naming – Naming each node in the network is as simple as double-clicking on the node name and typing in a new name as shown in Figure 40. This feature enables quick identification of nodes in the field and is especially useful in mission critical situations with many mobile assets. The user can click on the ‘Save Labels in Flash’ button in the left pane to store the node names to the radio’s flash memory. This will store the names on the radio even after the radio is powered off. The saved labels can also be cleared back to the defaults by clicking ‘Clear Labels in Flash’. The node labels set in one radio can also be broadcasted to other radios in the network by clicking the ‘Broadcast Node Labels’ button. Figure 40 Custom Node Naming

StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 67  Individual Node Characteristics – By simply rolling the mouse over any node in the network, users can view key operating characteristics of the node. Figure 41 shows an example of this for ‘node4568’. The characteristics shown are: o Node ID: The unique node ID assigned to each node at time of manufacture. This cannot be changed. o IP: IP address of the node. o Connections: Number of direct connections to node. Each directly connected node is listed in the following format: <Node Name> <RX SNR> <TX MCS> <Pkts in TX Queue> <Num. of Spatial Streams> <Air Time %><Data Rate (Mbps)><RSSI Ch1> <RSSI Ch2> <RSSI Ch3> <RSSI Ch4> Notes: - The ‘Air Time’ specifies the percentage of time the radio is transmitting. - Data rate shown is actual user data rate in Mbps. - MCS or NSS of N/A signifies that no data has been sent to that radio yet. o Frequency: RF center frequency of the node. o Bandwidth: RF bandwidth of the node. o Noise Level: Received noise level of the node. o Interference: Approximate in-band interference level. o TX Power: Total target transmit power of node. o TX Power (Actual): Actual transmit power of node. This value may differ from the target transmit due to temperature variation or inability to transmit a clean signal with the selected MCS at the target power. o Fragmentation Threshold: Chosen fragmentation threshold. o Virtual IP: Secondary IP address of node (0 if none set). o MCS Mode: Transmit MCS of node. o Link Distance: Link distance setting of node. o Burst Time: Burst time setting of node. o Routing Beacon Period: Routing Beacon Period setting of node.

StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 70 5.2.2 Network-wide Setup and Multicast Using the network-wide setup users can configure key parameters of every node in the network with just one click. Users simply need to check off the parameters they wish to be updated across the network and click on Apply to apply but not write new values to flash or Save and Apply to apply and save values to flash. The Broadcast Update Interval field determines how often, in seconds, the new parameters will be broadcast to the entire network. A list of all nodes will appear on the right with a check box next to each node. This box will be checked off as each node receives the update. Figure 43 Network-wide Setup

StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 71 5.2.2.1 Multicast The Network Wide Setup page is also used to configure up to 5 multicast streams. By default, all multicast/broadcast flows will be sent to all radios. This configuration is only necessary if a user wishes to send multicast streams to a subset of radios on the network. The configuration string format is as follows: Multicast_ip_address, receiver_id1, receiver_id2, … , receiver_idN Multicast_ip_address is the multicast group address and receiver_idN are the node ids of the radios that need to receive the multicast stream. If no receivers are indicated, multicast will be sent to all radios. If there is only one receiver id = -1, the multicast stream will not be put on the air and discarded at the transmitter. This allows a quick way for the user to turn off a multicast stream from anywhere on the network. Some Multicast examples: Data for multicast group 224.50.50.51 will be received only by radios with node-ids 1131 and 1261: 224.50.50.51, 1131, 1261 Data for multicast group 224.50.50.51 will be received by all radios: 224.50.50.51, Data for multicast group 224.50.50.51 will be discarded at the transmitter and not put on the air: 224.50.50.51, -1

StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 72 5.2.3 Per-Node Setup The per-node setup can be used to modify key parameters of individual nodes within the network. As shown in Figure 44, users will see a list of all nodes available within the network. The directly connected node is listed first with the rest ordered lexically. From here, users can click on an individual node and modify its parameters. Any parameters changed from this interface can either be applied or saved and applied. In addition, this page can be used to upgrade a radio’s firmware by simply choosing the upgrade image from your desktop and uploading it to the radio. This field can be used to upgrade the radio root file system, linux kernel, or uboot. The upgrade system accepts the root file system image for upgrade or a tar file containing up to 3 files (uboot, kernel, rootfs) for upgrade. A radio reboot will be required after update before the changes take effect. Figure 44 Per-Node Setup

StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 73 5.2.4 Map Overlay The Map Overlay page provides an easy to use method of tracking the location of nodes in real-time. Nodes with GPS modules attached will be placed on the map as shown in Figure 45. Figure 45 Map Overlay For convenience, a small copy of the network topology is displayed on the right hand side of the page. This allows users to clearly view the network characteristics in instances where nodes are physically close to one another and difficult to distinguish on the map overlay.

StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 74 5.2.4.1 Map Options There are 4 map options currently available in the Map Overlay view. The default map is OpenStreet Maps. OpenStreet Maps and OpenStreet Maps Silvus can be saved to the radio’s internal memory for offline use. For instructions to Download OpenStreet Maps into the radio, see section 5.2.4.2. OpenStreet Maps Silvus is a version of OpensStreet maps which is hosted on Silvus’ servers in case of an interruption in service with OpenStreet Maps. The Silvus maps currently only cover the United States. In Addition to OpenStreet Maps, Google Maps and Google Satellite are also available. This can be changed by clicking the ‘+’ symbol at the top right of the map: Figure 46 Google Maps Note that Google Maps and Google Satellite require an active internet connection on the viewing computer. These maps cannot be saved for offline use.

StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 75 Offline Map Image: In addition to the preset map options, the user can also upload a custom image or blueprint in place of the map. Figure 47 Offline Map Image To upload a custom image (800 x 600 pixels recommended), first choose the file from your desktop. You will then need to provide the image bounds. These bounds will be the latitude of the left and right bounds of the image and longitude of the top and bottom bounds of the image. Once entered, click upload and there will now be a 4th option when clicking the ‘+’ at the top left of the map overlay.

StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 76 5.2.4.2 Downloading Maps An internet connection is required to obtain map data, however, users can cache map data on a node beforehand. For map caching follow these steps: 1. Attach the radio to a laptop and open the advanced tab. 2. Set the Virtual IP address, netmask and gateway to values appropriate for your local network. Your local network should be able to access the internet. 3. Attach the radio to your local network and open the Map Overlay tab. 4. Input the address of the location you wish to download 5. You now have two options for caching map data: a. Zoom/pan around the area you are interested in at the zoom level you will be using. This will automatically cache the map data at this zoom level. b. Fill in the radius field (in meters), set the Min/Max zoom levels and click on ‘Seed the Map’. This is a beta feature and will attempt to cache the entire area for all appropriate zoom levels. Users should be careful in using this feature since it may take some time and will use up the radio’s available memory. For reference, a radius of ~3000m will use approximately 5 percent of the total memory.

StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 77 5.2.4.3 Manual GPS for Nodes without GPS Module Figure 48 Placing Nodes on the Map If there are nodes within the mesh that do not have a GPS module connected, or are located in an area with no GPS connectivity, the user can easily place the node on the map by right clicking on the desired location on the map and choosing which node to place there. These values will be ignored if GPS coordinates are available via a GPS module.

StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 78 6. Wired Backbone Wired Backbone extends the StreamCaster mesh functionality over LAN (Ethernet) and WAN (Internet) links. This feature is transparent to end-users - they do not have to re-configure their devices in any manner to use this feature. The StreamCaster routing protocol will automatically detect and route data on wired links to preserve air bandwidth. 6.1 LAN Backbone The LAN backbone feature allows more than one radio to be connected to a LAN. 6.1.1 Implementation One of these radios must be configured as a “gateway” radio. This radio then begins listening promiscuously on its ethernet interface to “register” all devices on the LAN as being connected to the gateway radio. At the same time it auto-detects other non-gateway radios connected to the LAN and establishes “wired” links to them. StreamScape Web GUI will show LAN links with SNR of 150 dB to differentiate from wireless links. The non-gateway radios do not register any devices, they merely act as relays. The gateway radio will forward traffic originating from the LAN, destined for a device attached to a wireless radio, to the non-gateway radio that is closest to the destination. Similarly, any traffic originating from a device attached to a remote wireless radio, destined to a device on the LAN will be forwarded by non-gateway radios to the gateway radio. The gateway radio will then send it to the device. Currently we support data rates of up to 65 Mbps on the LAN without encryption. Since all LAN traffic goes via the gateway radio, this is the upper limit of all traffic that can enter or go out of the LAN from/to devices connected to wireless radios. Of course, this limit does not affect the throughput between two devices connected directly to the LAN backbone. 6.1.2 Use Case Consider the following scenario. A business wants to do video monitoring of its grounds. High speed LAN hookups are available only in the HQ building. They want to use the StreamCaster radios on towers to provide complete coverage of the grounds. All video feeds are sent back and displayed at the HQ. To conserve air bandwidth and possible interference to other users, we want

StreamCaster MIMO Radio User Manual 10/7/16 10017C000 Silvus Technologies Confidential Page 79 video data to go through the high speed LAN backbone as much as possible. The below diagram shows the scenario. Towers 1-3 are equipped with IP cameras attached to StreamCaster radios 1-3. Radios 4-6 are mounted on three sides of the HQ building with their Ethernet interfaces connected to the high speed LAN. Tower 1 can only communicate wirelessly with radio 4, Tower 3 with radio 5 and Tower 2 with radio 6. Video from Tower 1 will flow wirelessly to radio 4, then via the LAN backbone to the HQ viewer which is also attached to the LAN backbone. Even though the radios 4-6 may communicate wirelessly, they will choose to do so via the LAN backbone. Figure 49 LAN Backbone Example

Multiple geographically separate “sites” can be connected into one single layer 2 network as long as each site has an uplink to the Internet. The roaming feature allows mobile devices connected to StreamCaster radios to roam from one site to another without any network re-configuration. 6.2.1 Implementation Each site wishing to become part of the wireless mesh needs to connect one StreamCaster radio to its LAN. Such a radio has to be configured to connect to a remote VPN server using the N2N protocol. Radios from multiple sites will be connected at layer 2 via the N2N VPN server creating a single broadcast domain for such nodes. By broadcasting routing packets in this domain, the nodes will auto-detect each other and establish WAN links. Such links will appear on the StreamScape GUI with a link SNR of 120 dB to differentiate from LAN links (150 dB) and wireless links. The N2N VPN server will try to establish peer-to-peer links between the radios if it can. Under some cases (e.g. symmetric NATs), this is not possible, in which case traffic between the peers is relayed by the N2N server. The N2N server can be hosted at any server with a public IP on the Internet. As a proof-of-concept, a server has been set up on Amazon Web Services. Currently we support up to 10 Mbps unencrypted between any two sites. 6.2.2 Use Case Consider a military scenario where a platoon of soldiers begins its mission at an HQ, then breaks up into two groups. Each group has at least one soldier with an uplink to the Internet (provided by a 4G card). The HQ also has an uplink to the Internet. Every soldier and the HQ have a StreamCaster radio attached to their devices. The soldiers in the two groups want seamless and transparent communication between 1) other soldiers in the same group 2) soldiers in the other group 3) back to HQ. Some lone soldiers (e.g. Soldier A with a StreamCaster radio) may break up from each group and move about on their own. As they get close to group 1, 2 or the HQ, they should be able to immediately establish communication and talk to all other soldiers in the network. The StreamCaster radios connected to the uplinks in Group 1-2 and the HQ will automatically connect and form WAN links. Note that the WAN and LAN backbone are complementary features. E.g. at the HQ, multiple radios can be connected to a LAN backbone so that any approaching soldier or group has a direct line of sight wireless connection to the HQ.

Custom Frequency Plan 7.1 Accessing and Installing CFP The hidden Custom Frequency Plan page can be accessed via http://<radio IP>/custom_freq.sh The interface will allow an upload of a custom frequency plan file which should be in the following format: { "type": "custom_frequency_plan", "name": "cfp_example", "description": "CFP Example", "frequencies": [ "2412", "2417", "2422", "2427", "2432", "2437", "2442", "2447", "2452", "2457", "2462", "2467", "2472", "5745", "5765", "5785", "5805", "5825" ] } (Put the above format in a Text file. Name/description can be changed) Custom Frequency Plan Text file example: https://drive.google.com/file/d/0ByThlCSjgHe1TDMtZ2xDXzhEblE/view?usp=sharing The numbers can be changed to the frequencies desired. The name of the text file does not matter in order to be utilized. After uploading the file, the web interface will be populated with the Custom Frequency Plan. Note: Once installed, the Custom Frequency Plan will be cross-checked with hardware capability and the licensed frequency range previously installed on the radio. The Custom Frequency Plan will only change what is displayed. It will not give new frequencies that are previously out of licensed range.$

Streaming Response Some users may be interested in streaming specific information from the radio e.g. RSSI, noise floor, temperature, etc. After enabling the response they need using the above commands, the radio will transmit the desired information in the form of UDP packets to a specific IP address and port. The format of each report message will be in the type-length-value format as shown below: TYPE LENGTH VALUE TYPE LENGTH VALUE …  TYPE and LENGTH will be 16-bit unsigned integers in network-endian format.  TYPE indicates the kind of information being transmitted. Pre-defined types are listed later in this document.  LENGTH indicates the length of the VALUE field in bytes, including the terminating null byte.  VALUE will be ASCII-encoded text terminated with a null byte ('\0').  A single report will comprise of a set of type-length-value fields beginning with a “begin” report type. It will have a type which is specific to the type of report being generated, length of 1 byte and a value of an empty string (“”). Note the empty string is still null terminated.  Each report will end with an end of report which has type 1 (type = end of report, length = 1, value = "").  The empty string listed above has a NULL character and has length 1. Any length number in the streaming report includes the NULL character  A UDP packet may contain more than one report.  The UDP packets have a maximum size of 1400 bytes.$
