From over-the-air power to neural computer control, each of these technologies has the ability to fundamentally alter the digital landscape. Put them together with the circuit advances we discussed last week, and you get a revolution in the way computers and electronics are designed, manufactured and used.
Extreme wireless: Multi-gigabit Wi-Fi
As great as it is to be able to grab data out of thin air, Wi-Fi is basically 1990s technology that's been jazzed up several times. "We want to take Wi-Fi truly into the 21st century," says Ali Sadri, president and chairman of the Wireless Gigabit Alliance. This consortium of tech companies has developed a specification known as WiGig () that supports wireless communications at multi-gigabit speeds.
"With the emphasis on high-definition video, usage of the Web is changing," notes Sadri, who is also marketing director for 's wireless group. "Unfortunately, Wi-Fi hasn't kept up. Faster is always better."
Wi-Fi depends on the IEEE's 802.11 family of standards. 802.11a equipment, introduced in 1999, operates on the 5GHz radio band, while later 802.11b and g devices use the crowded 2.4GHz band. The most current dual-band 802.11n gear can operate on either band. Each 802.11 update has increased Wi-Fi's speed incrementally.
