At present, many soldiers don’t have communications radios because the hardware is too expensive. Buying 2-way radios from Radio Shack before deployments solved that problem for some soldiers, but insecure communications created others. On the high end, the US military’s JTRS program is expected to create radios that are much better at working together, and much easier to upgrade. As one might expect, however, the hardware appears to be on track to be more expensive, in return for that improved performance.
The US Defense Advanced Research Projects Agency’s Wireless Network after Next (WNaN) program aims to shift the approach used to design these military wireless networks. It also intends to use inexpensive, high-volume, commercial off the shelf hardware components. They would be combined with adaptive wireless network software operating over densely-deployed, low-cost wireless nodes, with the aim of putting a reliable communications radio into the hands of every soldier. How could that work?
