Intel reveals Wimax wireless chip

Tech giant Intel has unveiled a chip that gives access to wide-reaching wireless networks. The new chip uses Wimax, which enables broadband connections over several miles, unlike the short range of wi-fi used in specific locations. The company has announced a series of trials with partners, including BT, around the world. Wimax is seen as a method of extending broadband reach to whole cities, rural areas and countries with low net use. It is also seen by some analysts as a potential competitor to mobile phone networks, although such a clash is still some way off.
