Ericsson: 5G Subscriptions Reach 1bn in 2023

E-mail Print PDF

According to the Ericsson Mobility Report 5G subscriptions will reach 1 billion by 2023, with 5G covering over 20% of the world population just 4 years after the first commercial 5G New Radio (NR) networks go live in 2019.

5g mobileA number of perhaps predictable markets will get the first 5G deployments-- namely the US, S. Korea, Japan and China-- all based in dense urban areas. The forecast period also involves an 8X surge in mobile data traffic, reaching 110 Exabytes per month (or 5.5 million years of HD video streaming) per month.

The mention of streaming is relevant, since video is a main driver of mobile broadband traffic. Young millennials (in the 15-24 age bracket) stream 2.5X more than people over 45 years of age, and higher resolution and immersive 360-degree video will further impact data traffic consumption volumes.

Magnesium Key for Bigger, Safer Batteries?

E-mail Print PDF

Berkeley Lab researchers announce a "major step" towards energy dense and safe solid-state magnesium-ion rechargeable batteries through the discovery of the fastest magnesium-ion solid-state conductor yet.

magnesium battery researchMagnesium promises higher energy density than the currently used lithium. However it lacks good options for liquid electrolyte, with most being actually corrosive against other parts of the battery. As a result, the researchers bypassed the liquid option in favour of creating a solid-state alternative, the impressively named magnesium scandium selenide spinel.

Wifi-Enabled Objects With No Battery Required!

Researchers at the University of Washington solve one of the issues the Internet of Things poses by 3D-printing plastic objects with built-in wifi capabilities-- no power source or electronics required!

Wifi object"Our goal was to create something that just comes out of your 3D printer at home and can send useful information to other devices," a team member says. "But the big challenge is how do you communicate wirelessly with wifi using only plastic? That's something that no one has been able to do before."

The team 3D-printed three wifi-enabled objects-- a weighing scale, a flow sensor and an anemometer able to measure wind speed using commercially available plastics and wifi receivers. A combination of 3D-printed springs, gears and switches (based on the same principles allowing battery-free watches to keep time) translates motion into antenna-transmitted data, while backscatter techniques reflect radio signals emitted by a wifi router or other devices.

G.Skill Presents DDR4-4266 CL17 Memory Kits

E-mail Print PDF

G.Skill announces a series of 16 and 32GB DDR4 memory kits for Intel Coffee Lake processors-- the CL17 Trident Z RGB DDR4-4266MHz, the first kits from the company offering speeds over DDR4-4000MHz with CL17 timings.

G.Skill memoryThe kits are made using "rigorously hand-binned" Samsung B-die DDR4 IC components, and are rated for DDR4-4000 CL17 17-17-37 at 1.35V, DDR4-4133 CL17 17-17-37 at 1.4V and DDR4-4266 CL17 18-18-38 at 1.45V. The consist of 8GB modules, and come with XMP2.0 SPD profiles to simplify installation on supporting platforms, namely Intel Z370-based motherboards.

Gigabyte Intros Radeon RX Vega 64 Gaming OC 8G

E-mail Print PDF

Gigabyte announces a first custom designed card based on the AMD Radeon Vega GPU-- the Radeon RX Vega 64 Gaming OC 8G, a black and red offering wrapped around a Windforce 2X cooler design.

Vega 64The Vega 64 features processors clocked at 1276 MHz base and 1560 MHz base, making it slightly faster than the 1247 MHz base and 1546 MHz boost clocks of the reference card. Allowing such speeds are a dual-fan Windforce 2X cooler, a "well rounded thermal solution" consisting of 5 heatpipes in direct contact with the GPU and a copper plate with an extra heatpipe on the back of the card.
