Amidst all the commotion of 5G technologies, electric vehicles, new technical innovations to reduce piracy and online crime, we have great news for you if you’re into technological findings. We are sure each and everyone of you has sometime or the other (or maybe once everyday) experienced the wrath of poor internet connectivity.


Even though the telecom companies today promise 4G connectivity all around the country at quit reasonable prices, to be honest we cannot expect the said deal on the same. The condition gets worse when one needs strong connection while doing some important job.


No one can agree more, with the problems faced due to

inadequate signal strength within homes and offices, prevailing

still at large. To solve this, the researchers at MIT, from the Computer

Science and Artificial Intelligence Laboratory (CSAIL) have developed a “smart

surface” that can boost signal strength up to 10 times.


RFocus: The Concept


Like we said, the researchers from MIT have developed a software-controlled “smart surface”, which promises to boost the signal strength up to 10 times.


The surface, named as RFocus is quite cost-effective and

contains 3,000 antennas that can boost  channel strength within

office walls by 2 times. This turns out to be quite helpful when multiple

devices are trying to access the same network, which is what generally

happens in an office premise.


According to the lead author of this research paper, ‘3000

antennas’ is the largest number of antennas ever used for a single

communication link.


The Miracles of RFocus


This RFocus can be easily installed on a wall and set up

between cubicles. Also, one of the core advantages  of this surface

is that it can be configured to act as a mirror or a lens depending on the

position of the device with respect to the receiver.


For anyone dealing with antennas and systems of similar

module, preservation of battery is an important parameter. Thus, in order to reduce

battery drain, systems often broadcast directed signals, which in turn reduces

power for signal strength to achieve that.


However, that requires receiving devices to include extra antennas or

increase the size of them at access points, which is pretty impractical and

here is where MIT’s new

solution can come in handy.


MIT professor Hari Balakrishnan said a system like RFocus might be really useful and cost-effective in a large space such as a warehouse.  He also added that this a promising solution for transmitting signals at low power.
