Data speeds and consumption are constantly growing, but the strain this puts on cellphone batteries and base stations has both frustrated users and increased overall power consumption. As MIT Technology Review reports, though, a new technology could turn that around. ETA Devices, founded by MIT professors Joel Dawson and David Perreault, is working on a system to cut base station power consumption in half and eventually do the same with smartphones.
"With high data rate communication, you wind up needing far more standby power than signal power."
The system works by optimizing the power amplifier, which converts electricity to radio signals in both cellphones and base stations. The amplifier works in both a high-power mode for sending...
