Northwestern University issued a press release on the 9th, saying that the school's researchers have developed a "wireless FM" technology. The technology can determine the optimal time for sending and receiving data according to the frequency modulation signal, and relieve network congestion, thereby improving the network speed.
Nowadays, the network bandwidth is constantly upgrading, but it is often the case that the webpage is "cracked". Obviously already connected to high bandwidth, how can it be slow? For this question, Alexander Kuzmanovic, an associate professor in the Department of Electrical Engineering and Computer Science at the McCorick School of Engineering, said that this may be because someone is using traffic and hindering the speed of the network.
Kuzmanovic and his two doctoral students, Marcel Flores and Yuri Karaman, found that using the radio can easily solve this problem. Flores said that many wireless networks in a certain area are often completely independent, although the "one room in the same room" can not achieve interconnection. In order to enable the isolated wireless network to achieve "communication", they "think wide open" think of FM (frequency modulation, which makes the instantaneous frequency of the carrier change according to the changing law of the required signal), and it will use "wireless network" Integrated, to achieve optimal configuration of network data, developed a "wireless frequency modulation" technology.
With "wireless FM", when a wireless data is occupied by two users at the same time, the data will be transmitted to the terminals of the two users first, and then the data start end will be returned without causing two people to "race" the data. , pull down the network speed. This is precisely because "wireless frequency modulation" can receive wireless network signals, and the direction of data transmission is controlled by frequency modulation to realize data transmission to users at the optimal time point. Flores pointed out that when the network conditions are optimal, "wireless FM" can send and receive data, and can guarantee the directional transmission of data without letting the data "run" to other devices.
Researchers believe that the application of FM technology on wireless networks has a certain foundation. First, since most smartphones and mobile devices have built-in FM chips. Secondly, FM technology is highly reliable and can pass through walls and buildings without interference.
On the 10th of this month, Flores presented the results at the 23rd Annual International Conference of Electrical and Electronics Engineers in San Francisco, USA.
Editor-in-chief
In the past, the reputation of radio enthusiasts is like today's "creator". Players have their own radio stations, self-installed TV, and have a good time. Since the rise of mobile phones and networks, the radio has faded. But mastering the radio skills, the effort is not in vain, plus the chip application and programming debugging, the radio application is still very promising. This FM technology solves data congestion as an example. Radio equipment will always be a good thing for geeks.
