Could Wireless Technology Really Be as Fast as Fiber-Optic Cables?



Could Wireless Technology Really Be as Fast as Fiber-Optic Cables?

In Japan, the National Institute of Information and Communication Technology and Panasonic are developing transmitters that are capable of transmitting over ten gigs of data over a terahertz connection (around 300 GHZ). Technicians are expecting these transmitters to be complete with CMOS integrated circuits (preventing them from getting corroded or overheating) making them a great option for commercialization and personal use. Technology in these fields could completely revolutionize wireless communication, giving users data rates that are literally ten times higher than any wireless technology will allow.

Faster, Cheaper Internet without Cords or Satellites

Technology considerations were presented at the International Solid-State Circuit Conference in San Francisco and met with great anticipation.

Ironically enough, the type of bandwidth (THz) is relatively new, and these types of frequencies hadn’t really been available for Wi-Fi connections and internet communication. The waves emitted are much wider than other bandwidths and even higher than millimeter waves (57 GHz to 66 GHz) that give higher wireless speeds that give users unlimited bandwidth on different networks.

Speeds that are Out of This World

Research groups started development on frequency ranges between 275 GHz to 305 GHz; and while these frequencies are unallocated on the wireless spectrum, they are expected to be allowed by the International Telecommunication Union Radiocommunication Sector (ITU-R).

Comparing these amazingly high speeds of the futuristic internet with average internet speeds that we have today is like comparing a turtle with a cheetah. Traditional internet speeds average frequencies around 5GHz or lower, and rely on modulation (that requires a ton of power) to amplify these signals to increase data rates in limited bandwidth channels. Researchers have even demonstrated GHz frequencies above 300 with CMOS circuits, and this combination could take wireless technology into a new generation that offers a completely revolutionized look at wireless communication speeds and wireless internet.

“Today, we get wireless data rates in megabits and gigabits per second. Soon, I think we’ll be talking about terabytes. That’s not too much of THz wireless technology. Soon, fiber optic speeds will be a thing of the past— and we’re starting to take important steps to reach this goal,” Prof. Minoru Fujishima. “We plan on developing circuits for 300 GHz bandwidths, modulation and demodulation of circuits for high-quality, ultra-speed communications.”
