May 20, 2013: With so many data
hungry websites (and apps) surrounding us all through the day, a slow Internet
connection is a bummer of sorts. Especially, if your wireless router does not
allow you enough freedom to move and still have the same impact. So hold your
breath as we tell you about a Wi-Fi router that can send a complete 2 hour full
HD movie over a kilometre in less than a second! Don’t believe us? Well,
researchers at the Karlsruhe Institute of Technology in Germany have managed
exactly that.
The hardware used to transmit the data at 240 GHz was created
by KIT and has a set of chips that is capable of sending high frequency
signals. In this case, the higher the frequency, the smaller the antenna size
to pick up the frequencies, which means faster transfer of data. “The number of
bits carried over the airwaves is in inverse proportion to that of the
wavelength. This means, the shorter the wavelength, the more data can be
transferred in a set period of time,” reports the official site of the Institute.
While the speed of a few MBs per second is becoming pretty
common, at higher frequency, the moisture levels in the air affect the signal
strength. Working on the issue, the research team realized that 240 GHz is the
spot where interference from moisture is the least. “The frequency range
between 200-280 GHz allows compact technical assembly as well. At 240 GHz, the
size of the transmitter/receiver chip measures only 4 x 1.5 sq.mm,” Crazy
Engineer reported
This can be a revolutionary breakthrough for areas where
fibre optics is not an option and can even bring down the cost considerably.
