5G- advanced, faster and better.

What is 5G?

5G is an advanced wireless technology that has begun wide deployment in 2019. 4 million Koreans have 5G phones in October 2019, with 5 million expected year-end. China has deployed over 100,000 base stations. 150 million 5G mobile subscribers are expected in 2020 in China. Nine companies are shipping 5G phones in December 2019, driving prices as low as US$470 in China. Indoor hubs, sometimes called MiFi, are available from Verizon in the US, Optus in Australia, Three in the UK and others. Virtually every major telco in the developed world is deploying or intends to deploy.

5G millimeter wave is the fastest, with actual speeds often of a gigabit or two. Verizon's 28 GHz network is the largest. Frequencies are above 24 GHz and soon up to 72 GHz. The reach is short, so more cells are required. mmWave 5G bands are 400 MHz, allowing much faster speeds than the lower bands of 20-100 MHz.. mmWave has difficulty traversing many walls and windows, so indoor coverage is limited.

5G mid-band is the most widely deployed, in over 20 networks. Speeds in a 100 MHz band are usually 100-400 megabits. In the lab and occasionally in the field, speeds can go over a gigabit. Frequencies deployed are from 2.4 GHz to 4.2 GHz. Sprint and China Mobile are using 2.5 GHz spectrum. Others are mostly between 3.3 and 4.2 GHz. Reach is better. Many areas can be covered simply by upgrading existing towers, which lowers the cost.5G- advanced, faster and better.

Hackers Can Shine Lasers at Your Alexa Device and Do Bad, Bad Things to It

Hackers Can Shine Lasers at Your Alexa Device and Do Bad, Bad Things to It Move the Echo away from the window. Now. By Courtney Linder Nov 6, 2019 A new paper funded by DARPA and a Japanese organization for the promotion of science and technology find that simple lasers can basically hack into voice-controlled assistants. Researchers are able to use lasers to inject malicious commands into smart devices, even remotely starting a victim's car if it's connected through a Google account. To be safe, keep your voice devices away from windows in your home. Keep Alexa away from all windows: Turns out hackers can shine lasers at your Google Assistant or Amazon Alexa-enabled devices and gain control of them, sending commands to the smart assistants or obtaining your valuable account information. Researchers proved this by using lasers to inject malicious commands into voice-controlled devices like smart speakers, tablets, and phones ...

MIT Little Robot Dog

It’s that time of year again — fall is here and packs of robot dogs are frolicking in the leaves Just listen to the scuttle of those tiny metal legs By James Vincent Share this story re this on Twitter (opens in new window) All sharing options There’s nothing I like more on bright and cold autumnal days than heading down to the park and watching the robot dogs playing in piles of leaves. To hear the scuttle of their little metal legs! To imagine the joy in their tiny silicon brains! Ah, what bliss. If you’ve not experienced these delights before, then the video above from MIT’s biomimetics lab will give you the basic idea. The bots you can see are the university’s Mini Cheetah: a lightweight and modular quadruped that’s been under development for years. We saw the Mini Cheetah earlier in 2019 when it learned to backflip , but the biomimetics lab has obviously cranked up production and now has at least nine of these littl...
