Power is usually the holy grail of mobile communications and mobile computing. No matter how powerful your phone's processor is, how big the screen, or how fluid the user interface, it will not amount to anything if the power supply is limited. This is why manufacturers and technologists have been trying to find ways to reduce power consumption, or at least find ways to improve efficiency in charging and power use. A startup is trying to improve power management by addressing the problem at its core: power amplifiers.
How MIT researchers may have solved the spectrum crunch using algebra
We all know that cell phone data signal is a funny thing. Sometimes packets get lost and and speeds drop to almost nothing in highly congested areas. MIT researchers may have figured out how to get passed that thanks to a little bit of algebra and a little bit of brilliance.
