Many users are less than satisfied with the range of their wireless equipment. After all, unless you're in the Nevada desert with a 10 foot antenna, its hard to get much range out of a 100 mW signal (the FCC limits wifi to this strength). The Japanese are trying to boost this.
Maspro Denkoh Corp., a Japanese manufacturer of wireless communications equipment, has developed a transmission system that can send Wi-Fi signals as far as five kilometers.
The system relies on high-gain antennas produced by the company and is compatible with standard 802.11b/g communications equipment, it said on Wednesday at the Ceatec Japan 2005 trade show in Chiba, Japan.
There are two types of antenna: One is a tube-shaped model about 40 centimeters long, and the other is a much shorter and square-shaped model. Combining two of the tubular antenna -- one on each end of the link -- will result in a transmission distance of about 5 km, while one of each antenna will work on distances up to 2 km, and two of the compact antenna will be fine for up to 1 km, the company said.
This would be a great product, except that it is over $5000. You may not want to throw away your Pringle's can yet. You can read some interesting discussion here about this.
