Bluetooth increases its range – Macitynet.it
The Bluetooth developer forum, which was held in recent days in San Jos, showed some interesting ideas for the development of this wireless technology. Some of these, such as those brought to public attention by IBM, will hardly ever find practical application. Others, however, are very promising, of which the most interesting was a different technological implementation of the protocol shown by TDK. The company that already produces numerous PCMCIA cards, in particular for the PC world, managed to extend the transmission distance up to 50 meters by simply using a ceramic antenna. The transmitter, initially, will be produced as a USB peripheral and will be destined for the portable market but later, thanks to its low consumption, it can also be used for other systems such as mobile phones and PDAs. very high resolution screen or a mobile phone for surfing the internet with a rear projector (on a screen cover) that shows enlarged images of the web pages. We remember that Bluetooth works on the same frequencies as 802.11, the Airport standard, of which it can become a dangerous competitor , although the transmission speed is to the benefit of the second.
