The Pentagon, at least, seems to think software-defined radios are a promising tool.

The more accessible software-defined radios become, he warned, the more that threat materializes.

General Dynamics has an advantage in the competition because it led the one part of the original joint program that actually delivered on the promise of software-defined radios.
Better to put cheap software-defined radios in the hands of penetration testers who can demonstrate the insecurity of those communications than to reserve the technology only for better-funded attackers who would exploit the same wireless communications in secret.

But it will face tough competition from BAE Systems, the only company that managed to be a key player in all of the originally conceived software-defined radios that would have been used by Army helicopters, ground vehicles and dismounted troops.
The story goes that the older versions have faulty power control software in their radios, forcing base stations to connect to phones at higher powers than they'd normally have to, which in turn leads to base stations running plumb out of power -- and once that happens, you get dropped calls, bad reception, and lousy data rates, among other UMTS ails.
ENGADGET: There can be only one: "source" claims for iPhone 2.0.2 to not suck, 2.0 must die
At the time, smart money was pouring into software, chips, radios, glass and genes.
Even if the Nasdaq as a whole returned to Earth, smart money would keep searching for innovation in software, chips, radios, glass and genes.
The common interface standards mean that there are rules for constructing the hardware and software used in the family of radios so that even though they may have different configurations and users, they can all communicate when their settings match.
FORBES: New Radio Could Revolutionize Combat for U.S. Forces
To do that, Intel whipped up some software that effectively rewrites the way the two radios communicate with one another, in particular by eliminating the extra data sent confirming transmissions.
