The core of the small (portable) node is based on small-form-factor PC (i.e. Intel NUC based platform) with number of internal peripherals (solid-state storage, AC WiFi, Bluetooth, etc.) as well as external peripherals (USB3 attached custom sensor pack, 4G modem, etc.) – see Figure below. The compartment below the main board contains a management unit (CM), small sub-6GHz SDR and a battery pack with the electronics supporting variety of power sources. The whole package it is roughly 4 inches on a side and consumes between 40W and 80W (depending on the choice of CPU and peripherals/sensors) simplifying in vehicle installation and even enabling backpack type deployments.
