Some operating conditions create a difficult radio environment for the system to maintain link between the aircraft and the GCS. These conditions can include distance, dense structures, interference within the radio environment, or some combination of these conditions. While many UAS only have a direct link to their GCS, Arrowhead has the ability to utilize a mesh network that allows data to have multiple paths to and from the drone.
One way to consider how this works is like a Wi-Fi extender that you may use in your home or office. The extender connects to the original source, and reamplifies it so that you can have a better connection further away from that original source. Another way to visualize this is that the signal can “bend” around areas of a structure to minimize interference.
Utilizing the Mesh node to allow for the most direct and clear path to the aircraft will give the end user the best result and experience. To do this think as if you were to shooting a lasers to all the devices in the system. For everything that the “laser” is going to have to go through, range will be reduced. If the “lasers” path is free and clear your range will be at its greatest.

Mesh Nodes will not assist your connectivity range when powered on and sitting right next to the operator of the aircraft. This is because the Mesh Node is in no more of an advantageous position than the GCS is itself. A good way to consider using Mesh Nodes, is to inform members of the team that will be entering the building to place down the Mesh Node on a table after clearing a room or two within the building.

Operating the Mesh Node Range Extender is very easy. First make sure the antennas are securely connected. Then simply connect the power cable from the Mesh Node to one of your Arrowhead batteries. The Mesh Node will instantly power on, and within 60-seconds should connect to the GCS and UAS to create the mesh network. As you power on additional Mesh Nodes they should join the network they are assigned to automatically

Please note that Mesh Nodes only work with their assigned GCS/UAS.

On an Arrowhead battery the Mesh Node can run for several hours. The active fan on the Mesh Node will also allow it to remain within operating temperatures throughout the duration of operation. Once the Mesh Node is powered on and placed appropriately there is nothing else you need to do until the end of the operation.
