StonyandCher writes: Although the recent auctioning of the 700MHz wireless spectrum bands have garnered great interest in the media (not to mention the billions of dollars being thrown around to own some of this), it's not the be-all and end-all answer to our wireless hunger.

New research is starting to be conducted in the area of infrared radiation. Cheap to develop infrastructure for, super fast and with huge amounts of spectrum available (literally many terahertz), is this the unlicensed answer to the dearth of wireless spectrum? This article delves deeper into the world of IR and looks at its pros and foibles.

Submission + - Start an IT career at age 40? 2

An anonymous reader writes: How viable is it to start an IT career at age 40? I have heard there is a lot of age bias in the IT industry. I have a science degree and programming experience, and I think IT would be more interesting and higher paying. Anybody have any hints on getting your foot in the door? How bad is the age bias and will it make a career too difficult to maintain? (I have heard of 40-year-olds losing their job and taking years to get a new one in the IT industry)
