What does it mean that digital technologies are increasingly a part of...
Engineers at NC State University (NCSU) have discovered a way of boosting the throughput of busy WiFi networks by up to 700%. Perhaps most importantly, the breakthrough is purely software-based, meaning it could be rolled out to existing WiFi networks relatively easily — instantly improving the throughput and latency of the network.
I found the description at ExtremeTech to be extremely unintelligible. I will look for other descriptions of how this new algorithm works.
New antenna speeds up Wi-Fi by 200x.
Researchers in Singapore have developed a tiny antenna able to produce wireless speeds of 20-Gbits per second, which is 200 times faster than current Wi-Fi speeds.
The tiny device measures 1.6 x 1.2mm, which also makes it the smallest silicone based antenna to date. The antenna differs from previous antennas by being filled with a polymer instead of air, and the team says the technique is suitable for mass production.
I recently suggested that 5G wireless — a 1 gigabit connection provided directly by cell companies — is the key to breaking the cable monopoly, for both TV and internet. This antenna technology might be part of that.
Light-based data transmission technology is attractive because it allows wireless communication without the use of radio gear, which can be dangerous in places like oil platforms (where it can cause sparks) and underwater (where the salt conducts electricity), or on planes (where it can interfere with other radio equipment). In addition, transmissions can be stopped simply by blocking the light, and thus can be stopped by walls, so there is less risk of data leaking out of a house or office. And researchers say they believe that signals can piggyback on lights that are already in use — street lamps, car headlights or room lighting. Indeed, Klipsch, a speaker manufacturer, last year introduced speakers which could receive music data from normal LED lightbulbs in the home.
The future of wifi is lifi.
