Clearwire

My friend told me today about an Internet service called Clearwire that his company is using. It’s very intriguing.

Clearwire works by providing wireless Internet to users through structures similar to cell phone towers. Once the user sets up a special router, he can connect his computer or network to it in various ways:

Speeds on the service are as high as 1.5 or 2 Mbps–certainly much faster than dial-up.

One advantage (or, some say, disadvantage) is Clearwire’s use of the licensed radio frequencies at 2.5 GHz. This makes it more secure than typical Wi-Fi, which uses unlicensed (and therefore more open but also more vulnerable) frequencies of 2.4 GHz. (Read the FAQ on their website, under About Clearwire.)
