CNET talks about a new wireless technology call xMax which can help other technologies such as WiMax and 3G to fulfill their promise. The xMax technology is developed by xG Technology and will control power management to significantly lower power consumption:
"Power consumption is the No. 1 issue in any mobile application," said Craig Mathias, a principal at Farpoint Group, a consultancy specializing in wireless and mobile technologies.

xG claims the technology could mean that in the future talk times for cell phones will be comparable to today's standby times.
