The non-WiMax players are currently working to converge their technologies into a single standard called LTE (long-term evolution). You will hear a lot more about this in the next 12 to 24 months. This technology is based entirely on the IP standard used by the Internet.

In North America, ATT and Verizon are currently rolling out WiMax at an accelerated pace in some of their markets. WiMax USB adapters (required to hook up the laptop to the service) are becoming available. Intel, the world's largest manufacturer of computer motherboards and central processing units (the brain of the computer) has committed to building WiMax capabilities into new laptop designs going forward.

So, whereas 3G is primarily a phone experience, 4G will be primarily a laptop experience. But do not think in terms of the bulky computers of the past. Today, the netbook is as small as a pad of paper that can fit into a purse. Very shortly, you will see persons having full internet experience on a laptop with a nine-inch screen.

Travelling executive

These devices will facilitate the travelling executive much more than the current offerings. Schoolchildren will be able to do their homework on the bus and carry out project research while having their snacks at their favourite hamburger joint. Will they be watching their favourite movies streamed directly from the Internet? Your guess is as good as mine.

This is what the fuss is all about. Carriers expect to make significant profits from the enhanced services while consumers can look forward to more interactive experiences while on the go. It will be cool stuff.
