Low-SWaP (Size, Weight, and Power)
Low-SWaP refers to systems designed to minimize size, weight, and power consumption — the three primary constraints for man-portable, vehicle-mounted, and UAV-carried equipment. In military and expeditionary contexts, every gram, cubic centimeter, and milliwatt matters: operators carry communications equipment alongside weapons, ammunition, water, and medical supplies. Vehicle and drone platforms have strict payload budgets. Battery life directly limits mission duration. Low-SWaP design requires efficient algorithms (minimal CPU cycles), small code footprints (minimal memory), and low-power radio interfaces (minimal transmission power and duration). The trend toward tactical edge computing — pushing computation closer to the point of action — intensifies SWaP pressure as more capability is demanded from smaller platforms.
How XO Defense Addresses This
XO Defense's protocol stack is inherently low-SWaP. The 25-byte Mustard Envelope minimizes transmission power and duration. The protocol logic operates on fixed-length binary structures without complex parsing, reducing CPU requirements. No persistent network connections means no background keepalive traffic consuming power. The entire protocol stack can run on embedded microcontrollers (ARM Cortex-M class) without requiring Linux or a full operating system. This makes XO Defense protocols deployable on platforms ranging from smartphones to IoT sensors to UAV payloads, all within tight SWaP budgets.
