Apple could launch an iPhone 5G in 2020

English, Future, Gadgets

The project for the next generation of 5G networks is only in its early stages, but that will not prevent phone manufacturers from incorporating 5G capabilities into their phones as soon as possible. According to a new report, Apple will join the party in 2020.

 

Internal sources say that the Intel 8161 5G modem chip will be the one that will provide this 5G connectivity, although apparently Intel is fighting the heat problems that the prototype of the chip seems to have and thus develop it for commercial use.

 

It seems that Apple is willing to allow other companies to reach the market first with their 5G phones. Oppo, LG, Samsung, Huawei, Lenovo and Sony have confirmed or have at least said that 5G phones will be launched in 2019.

 

Speed ​​is priority

Depending on where you live in the world, you may have become accustomed to seeing the 4G or LTE symbol on your phone on a regular basis. The deployment of 5G in terms of real networks will be delayed with respect to the arrival of phones with 5G capacity; As with 4G, it will first appear to the inhabitants of the main cities, and then it will be extended to other places.

 

The improvements that 5G will offer us are not only reside in brutal speed, but also in the band, which will be wider. That means that it allows the connection of more devices at the same time and that there will be a better reception when we are in very busy areas.

 

Download speeds have the potential to be a thousand times faster than 4G – 10Gbps instead of 100Mbps – although this is a theoretical maximum (the reality will be somewhat different). By the time Apple’s rumored iPhone 5G arrives in 2020, you may even be able to connect to a 5G network somewhere near where you live.

Researchers discover a new way to identify 3D printed weapons

Researchers at the University of Buffalo have discovered that 3D printers have fingerprints, essentially small differences in design that can be used to identify prints. This means that researchers can examine the layers of a 3D printed object and point out exactly which machine produced the parts. “3D printing has many wonderful uses, but it is also a counterfeiter’s dream. Even more worrying, it has the potential to make firearms more readily available to people who are not allowed to own them,” said Wenyao Xu, lead author of the study. The researchers found that small wrinkles can be used on each layer of plastic to identify the type of printer model, the filament, the size of the nozzle and other factors that cause slight imperfections in the patterns. They call their technology PrinTracker.

“Like a fingerprint for a person, these patterns are unique. As a result, they can be traced to the 3D printer,” the researchers wrote. This process works primarily with FDM printers such as the Makerbot, which uses long filament coils to deposit plastic layers on a construction board. Because the printers used in 3D printed guns are generally more complex and more expensive, there could be less variation in individual layers and, more importantly, layers may be more difficult to discern. However, for some simpler plastic parts there may be variations. “3D printers are designed to be the same. But there are slight variations in their hardware created during the manufacturing process that lead to unique, unavoidable and immutable patterns on every object they print” said Xu.
