Next, it allows you to accept and ignore known transmitters, such as your tablet, your home WiFi network and your neighbors’ devices. The system then only becomes concerned with unknown signals and other RF signals in the 1MHz – 6.8GHz range and brings them to your attention. Drone contact signal strength
If the signal is not purposely ignored by you, then the system assumes that the rogue transmitter is hostile. The screen above shows signal strength of the unknown transmitter and alerts you to its presence within the mesh grid. It sounds an alarm (which can be disabled) or notifies you via WiFi to your tablet or smartphone.
The Primary Command and Control Module are based on the Linux operating system running on APlus Mobile’s MotherBone™PiOne™ open source software platform.
The module and nodes utilize a mesh network that only communicates within itself, but the Primary Command and Control Module can communicate with your personal WiFi network as an isolated device. Neither the module nor nodes extend your personal WiFi network so your WiFi network is not susceptible to outside hacking or infiltration through the mesh grid.
Why it Works
The Drone Detection Grid is essentially a custom wireless mesh network and its advantages include:
THE BASIC DRONE DETECTION SYSTEM
The Basic Personal Drone Detection System consists of three boxes: a Primary Command and Control Module and two Detection Sensor Nodes. These three boxes create a mesh network that can triangulate moving transmitters.
Triangulation of Drone Transmitters
The Primary Command and Control Module communicates with the detection sensor nodes via WiFi. The Detection Nodes also independently detect Radio Frequency (RF) transmitters in the range of 1MHz – 6.8GHz in order to effectively detect all known drone transmitters.
The Primary Command and Control Module offers a simplified user interface via WiFi, such as through your tablet, smartphone or PC. The Module can also be connected to a monitor or TV via HDMI. Identification of all local transmitters

Wireless mesh nodes are easy to install and uninstall, making the Detection network extremely adaptable and expandable
as more or less coverage is needed.
The Personal Drone Detection System sensor network is expandable to include additional Detection Sensor Nodes to
provide large area coverage. Additional Sensor Detection Nodes can be purchased to increase the size of your wireless
mesh grid. This enables scaling of the detection system automatically as described in Wikipedia here.
Command and Control Modules can be linked together to form a larger coordinated detection array. Mesh Network using Multiple Detection Nodes
Mesh Coverage Diagram
The Primary Command and Control Module can typically communicate with nodes up to 200 feet away.
Each RF Sensor Node can typically detect drones within 50 feet in all directions. Frequency detection range 1MHz – 6.8GHz.
When first installed, the Personal Drone Detection System identifies all local transmitters and signal strengths as shown above. Accepting and ignoring known transmitters
Detection Grids are “self configuring;” the network automatically incorporates a new node into the existing structure without needing any adjustments by a network administrator.
