Rolling out in most of its cities starting next year.

Google Fiber will double the maximum internet speed offered to its customers starting later this year from 1 Gbps to 2 Gbps, the company announced this week. The new plan will cost $100 a month, $30 more than the company’s existing 1 Gbps option. However, only downloads will be offered at the new maximum speed; uploads will remain at 1 Gbps. With the new plan, Google says it will provide customers with an unspecified “new Wi-Fi 6 router and mesh extender” to make the most of the new speeds.

Pilots of the new plan are due to kick off in Nashville, Tennessee, and Huntsville, Alabama, next month, with a full rollout in the two cities planned for later in the year. The company says it currently offers Google Fiber and Google Fiber Webpass (which uses over-the-air transmission rather than fiber optic cables) in 19 cities in the US. 2 Gbps pilots are due to start in its other markets later this year, with a rollout in “most” cities in early 2021.

The future of enterprise tech won’t be confined to the data center mothership — nor even the public cloud. Wedded to the internet of things, edge computing puts processing horsepower wherever it needs to go.

The company disclosed the benchmarks in a presentation to the FCC.

With thousands of students using the internet to attend class remotely, cybersecurity experts are raising concerns about children becoming targets for hackers. Many Central New York school districts, like the Central Square Central School District, sent laptops home with students. Central Square uses a software called GoGuardian that flags unsafe or inappropriate online material. Superintendent Thomas Colabufo says parents are happy to know that the security feature is in place.

Brisbane, Australia, September 4, 2020 —Exponentially increasing numbers of announced ambitious NGSO (Non-Geo Stationary Orbit) or LEO-HTS (Lower Earth Orbit – High Throughput Satellites) Mega Constellations have been creating waves in the world of technology. Their success will not be a mere disruption to the existing system, it will be a whole new system altogether.

Future wireless networks of the 6th generation (6G) will consist of a multitude of small radio cells that need to be connected by broadband communication links. In this context, wireless transmission at THz frequencies represents a particularly attractive and flexible solution. Researchers at Karlsruhe Institute of Technology (KIT) have now developed a novel concept for low-cost terahertz receivers that consist of a single diode in combination with a dedicated signal processing technique. In a proof-of-concept experiment, the team demonstrated transmission at a data rate of 115 Gbit/s and a carrier frequency of 0.3 THz over a distance of 110 meters. The results are reported in Nature Photonics.

5G will be followed by 6G: The sixth generation of mobile communications promises even higher data rates, shorter latency, and strongly increased densities of terminal devices, while exploiting Artificial Intelligence (AI) to control devices or autonomous vehicles in the Internet-of-Things era. “To simultaneously serve as many users as possible and to transmit data at utmost speed, future wireless networks will consist of a large number of small radio cells,” explains Professor Christian Koos, who works on 6G technologies at KIT together with his colleague Professor Sebastian Randel. In these radio cells, distances are short such that high data rates can be transmitted with minimum energy consumption and low electromagnetic immission. The associated base stations will be compact and can easily be mounted to building facades or street lights.

To form a powerful and flexible network, these base stations need to be connected by high-speed wireless links that offer data rates of tens or even hundreds of gigabits per second (Gbit/s). This may be accomplished by terahertz carrier waves, which occupy the frequency range between microwaves and infrared light waves. However, terahertz receivers are still rather complex and expensive and often represent the bandwidht bottleneck of the entire link. In cooperation with Virginia Diodes (VDI) in Charlottesville, U.S., researchers of KIT’s Institute of Photonics and Quantum Electronics (IPQ), Institute of Microstructure Technology (IMT), and Institute for Beam Physics and Technology (IBPT) have now demonstrated a particularly simple inexpensive receiver for terahertz signals. The concept is presented in Nature Photonics.
