It can either be used as a wireless bridge, placed on your robot, connected to the robot controller or as an indoor wireless access point connected to your robot driver station. By configuring the VH-109 radio as a wireless bridge, you'll be able to wirelessly connect your robot controller to the field side network connected to your robot driver station. When configured as a WIRELESS ACCESS POINT, due to regulatory requirements, the VH-

109 radio cannot be powered using a battery source and is for indoor use only. The device is regulated by the FCC LPI (Low Power Indoor) requirements when in this mode. At this time, the product is powered by AC power POE Only when the VH-109 radio is configured as an Indoor Clients may it be powered using a battery. Mounting your Radio The radio should be mounted against a metal tube or plate. It is recommended that teams mount against a metal tube/plate to act as a heatsink for the radio during extended operation. Zip tie notches are included in the event that teams opt out of using VHB or another adhesive to attach the radio to their robots. Wiring Your Radio Powering your Radio The VH-109 radio was designed to operate directly off battery voltage but is compatible with the sources of radio power for the OM5P radio. The radio can also be dual powered using both the 12V Weidmuller DC input or using Passive Power over Ethernet on the RIO port simultaneously however, the inputs need the SAME source and voltage. When configured as a wireless access point, due to regulatory requirements, the VH-109 radio cannot be powered using a battery source. The device is regulated by the FCC LPI (Low Power Indoor) requirements when in this mode. When configured as a wireless access point, the device must be powered using an AC to DC adapter that is sold separately. Programming your Radio Configuring your computer When at an official FIRST event, the Vivid-Hosting Radio Kiosk will be available for teams to easily program their radios with a GUI interface. The configuring computer must have it's network interface configured with an IP address in the 192.168.69.0/24 subnet to reach the management IP of the VH-109 radio. For example, the network interface on your driver station laptop can be temporarily configured to:

IP Address: 192.168.69.2 Subnet Mask: 255.255.255.0 Gateway: Leave Blank DNS: 192.168.69.1 or Leave Blank Programming your Radio Navigate to http://192.168.69.1:8081/

(213) 985-1771 Exhibit #4: Mounting instructions for 6XD Use Case (Mounting to a Robot) Mounting Your Radio Overview Properly mounting your radio is an important first step to making sure your robot connects to the field and remains connected throughout a match. Here are some initial considerations when thinking about where to mount the radio on your robot:

Consideration The radio should be mounted against a metal tube or plate. Reason Heat can build up inside the radio. By mounting the radio against a metal surface, you can conduct heat away. These LEDs are used by field staff to diagnose connectivity problems. Without these LEDs it becomes much harder to troubleshoot why your robot may be having connection issues. The antennas inside the radio have a radiation pattern. Having objects pass too close the radio can alter this radiation pattern, and adversely affect how well the radio is able to communicate with the field. Do not block the visibility of the status LEDs. Avoid having objects within 12" of the radio (Not including the back of the radio, opposite the status LEDs). It is recommended that teams mount against a metal tube/plate to act as a heatsink for the radio during extended operation. Mounting Examples Here are some examples of ways you can mount the radio to your robot. In each of these examples we'll discuss why it's good or bad. The radiation patterns shown in the renders below are meant to be representative of the affect different mounting locations have on radio performance. Example #1 Vivid-Hosting, LLC 4275 Executive Square Suite 206 La Jolla, CA 92037

(213) 985-1771 In this configuration the radio is mounted on the outside of the robot's structure, with the status LEDs pointed towards the outside of the robot. Vivid-Hosting, LLC 4275 Executive Square Suite 206 La Jolla, CA 92037

(213) 985-1771 Isometric view of the VH-109's radiation pattern in this mounting configuration Vivid-Hosting, LLC 4275 Executive Square Suite 206 La Jolla, CA 92037

(213) 985-1771 Side view of the VH-109's radiation pattern in this mounting configuration Vivid-Hosting, LLC 4275 Executive Square Suite 206 La Jolla, CA 92037

(213) 985-1771 Top view of the VH-109's radiation pattern in this mounting configuration This is the best configuration because it creates the least amount of interference for the radio's antennas. The status LEDs are visible and make it easy for field staff to read them. The radio is mounted relatively high on the robot. There are very few metal obstructions around the antenna. Final Verdict: Best Example #2 Vivid-Hosting, LLC 4275 Executive Square Suite 206 La Jolla, CA 92037

(213) 985-1771 In this configuration the radio is mounted between the robot's a-frame, with the status LEDs pointed towards the outside of the robot. However, there is a transparent plastic panel covering the status LEDs. Vivid-Hosting, LLC 4275 Executive Square Suite 206 La Jolla, CA 92037

(213) 985-1771 Isometric view of the VH-109's radiation pattern in this mounting configuration Vivid-Hosting, LLC 4275 Executive Square Suite 206 La Jolla, CA 92037

(213) 985-1771 Side view of the VH-109's radiation pattern in this mounting configuration Vivid-Hosting, LLC 4275 Executive Square Suite 206 La Jolla, CA 92037

(213) 985-1771 Top view of the VH-109's radiation pattern in this mounting configuration This configuration is not the best but is still acceptable. The robot's a-frame is surrounding the sides of the radio, which will affect antenna performance. However, the plastic panel doesn't impact antenna performance, which allows the radio to create a good link with the field access point (AP). Final Verdict: Acceptable Example #3 Vivid-Hosting, LLC 4275 Executive Square Suite 206 La Jolla, CA 92037

(213) 985-1771 In this configuration the radio is mounted between the robot's a-frame, with the status LEDs pointed towards the centerline of the robot. Vivid-Hosting, LLC 4275 Executive Square Suite 206 La Jolla, CA 92037

(213) 985-1771 Isometric view of the VH-109's radiation pattern in this mounting configuration Vivid-Hosting, LLC 4275 Executive Square Suite 206 La Jolla, CA 92037

(213) 985-1771 Side view of the VH-109's radiation pattern in this mounting configuration Vivid-Hosting, LLC 4275 Executive Square Suite 206 La Jolla, CA 92037

(213) 985-1771 Top view of the VH-109's radiation pattern in this mounting configuration This is not a good mounting location for the radio. First, field staff will have a harder time seeing the status LEDs, which will make it harder for them to help you troubleshoot your robot. More importantly, the radio is broadcasting its signal into the rest of the robot's structure. This configuration has a greater impact on antenna performance, and likely cause the robot to have communication problems with the field access point (AP). Final Verdict: Not Recommended Example #4 Vivid-Hosting, LLC 4275 Executive Square Suite 206 La Jolla, CA 92037

(213) 985-1771 In this configuration the radio is mounted on a plate with the rest of the robot's electronics. The status LEDs are pointing upwards. Vivid-Hosting, LLC 4275 Executive Square Suite 206 La Jolla, CA 92037

(213) 985-1771 Isometric view of the VH-109's radiation pattern in this mounting configuration Vivid-Hosting, LLC 4275 Executive Square Suite 206 La Jolla, CA 92037

(213) 985-1771 Side view of the VH-109's radiation pattern in this mounting configuration Vivid-Hosting, LLC 4275 Executive Square Suite 206 La Jolla, CA 92037

(213) 985-1771 Top view of the VH-109's radiation pattern in this mounting configuration This scenario depends on other factors to determine if it could be satisfactory. In this specific example, the radio is broadcasting into an arm, which is going to negatively impact performance. If there were no obstructions above the radio, then this would be an acceptable configuration. Final Verdict: Depends Example #5 Vivid-Hosting, LLC 4275 Executive Square Suite 206 La Jolla, CA 92037

(213) 985-1771 In this configuration the radio is mounted on a plate with the rest of the robot's electronics. The status LEDs are pointing downward (towards the ground). Vivid-Hosting, LLC 4275 Executive Square Suite 206 La Jolla, CA 92037

(213) 985-1771 Side view of the VH-109's radiation pattern in this mounting configuration Vivid-Hosting, LLC 4275 Executive Square Suite 206 La Jolla, CA 92037

(213) 985-1771 Top view of the VH-109's radiation pattern in this mounting configuration This is one of the worst ways you can mount your radio. In this scenario the radio is broadcasting into the ground, which has a significant impact on performance. In this scenario the field access point (AP) will likely have a hard time maintaining a good connection to the radio throughout the match. Final Verdict: Not Acceptable Vivid-Hosting, LLC 4275 Executive Square Suite 206 La Jolla, CA 92037

(213) 985-1771 How To Mount Your Radio There are two recommended methods to mount your radio. Zip Ties The radio housing has two notches on either side. These notches are sized to fit a 1/4" wide zip tie (McMaster-Carr P/N 70215K57). When zip ties can be run through these notches and around a part of your robot's structure to rigidly mount the radio to the robot. Removing the radio is easy, just cut the zip ties and unplug the cables. VHB Tape Another recommended solution is to use VHB tape. This is a high strength foam tape that can create a rigid mechanical connection between your robot and the radio. Here are some examples of recommended VHB tape:

Thickness x Width Supplier / Part Number 0.045" x 0.500" McMaster-Carr / 8127A51 McMaster-Carr / 8127A53 0.045" x 1"

McMaster-Carr / 8127A61 0.045" x 2"

It's possible to remove the radio when using VHB, but keep in mind that VHB creates a more permanent bond than zip ties. Removing a radio mounted with VHB will require some force. Be careful not to damage your radio in the process of removing it. Zip tie notches are included in the event that teams opt out of using VHB or another adhesive to attach the radio to their robots.

We, Vivid-Hosting, LLC., would like to provide usage guidance for device under FCC ID: 2BBOU10923. The noted FCC ID above is otherwise known as the VH-109 device. The VH-109 device was a device designed for exclusive use within a high school robotics competition called FIRST Robotics Competition. More information about the competition can be found at https://firstinspires.org. The robotics competition operates under the premise of a 3 versus 3 on field competition using student designed robotics chassis that are often around 24 inches by 24 inches by 48 inches, weighing in at approximately 145 lbs. These robots operate within a closed indoor field environment where humans are controlling the robots from a safe distance, behind field structures that contain the robots. The wireless environment currently utilizes a 5 GHz WiFI access point on the field side and a WiFi STA on the robot side. Were intending to use the VH-109 devices at the FIRST Championship in April of 2024. Weve performed 6ID testing for our field side configuration along with the 6XD testing for the robot side. As stated in our other letter, RE: Part 2, Subpart J, Radiofrequency Radiation Exposure, we believe that this device cannot be used outside of our robotics application as there is hardware and software requirements to enable its use within the robotics field. There will be no usage of these devices outside of their intended application within the FIRST Robotics Competition. Were intending to provide the VH-109 device to be used as a next generation wireless communications device for both the field access point and STA on the robot. By introducing the latest wireless technologies, especially in the 6 GHz environment, we will empower students to learn and innovate.
