WiFi has conquered laptops a long time ago and slowly but surely it is becoming a basic feature of high-end mobile phones. Compared to Bluetooth, WiFi has higher range and much higher speed (11 and 54 megabit). The Melbourne University-based laboratories (Australia) unveiled a new wireless technology called GiFi. This is a short range technology, effective within 10 meters. However it features impressive data transfer speeds – 5 gigabits per second, it can transmit stream video online without buffer delays. The developers have already held a demo of GiFi in action. They introduced a 5-mm CMOS-chip that uses a one-millimeter antenna and consumes mere 2 Watts. GiFi works in the 60 GHz spectrum and would have a production cost less than $10. The final GiFi version is expected in 2009 or later. The developers believe the new wireless technology will be widely applied in household electronics like TVs and mobile phones.
