AT&T announced on Friday to begin testing 5G technology, with a potential limited commercial offering before the end of 2016. 5G is promising to improve the speed of the fastest wireless network today with a factor of 10 to 100 using millimeter waves, virtual network functionality and defined networks. Software

By collaborating with Ericsson and Intel, AT&T will accelerate its efforts to bring 5G to market from the second quarter of this year. The company said the planned tests track extensive research, patent registrations and software development networks that allow AT&T to update the system without touching devices – a faster way to introduce new versions of software and technology More efficient way.

Bumps in 5G Road

The race towards 5G is not without challenges. It is not easy to build a fixed broadband network that provides at least gigabit speeds for customers and corporate customers.

“Some of AT & T’s things that are strength and performance in the event of rain and other disastrous weather conditions, like Ola,” said Fletcher Cook of AVP Global Media Communications at AT&T.

AT&T said it was working hard with the IEEE to set standardized standards. “One piece of standards is the biggest hurdle. Determining how networks operate between carriers and how these standards are set up are two things we explore.”

Driving force

Advances in modern technologies, along with the increased use of smartphones for bandwidth video consumption, drive AT&T and other companies to operate and operate 5 networks.

Marketing agencies also jump through the cart of new technology.

For example, YouTube360, Facebook360 and Little Star have a lot of Fortune 500 brands creating content; it’s a new way to get their message across. Way. ”

The trick will be to search for enough bandwidth to render this content natively. As more and more people invested in affordable ways to view VR content – such as Google Cardboard that only requires visuals (as low as $ 6.99) and a smartphone – demand for faster speeds and greater bandwidth increases.

Austin Maas, Subversive CEO, Note: “Virtual reality content requires a lot of bandwidth.”

A change made by Google to the Chrome 79 WebView icon, which the development team believes was caused by the problem in beta six weeks ago. On Sunday, a Google software engineer suggested that if the issue was raised at this point, Google could address it before it significantly affected users.

Summary of symptoms

Google engineers are sure that the lost data is the result of a change in the storage location. However, correcting this symbol to eliminate the problem remains a challenge for engineers. As of now there is no guarantee that the fix will return the lost data in the affected Android app.

Some Android apps run inside WebView. This includes applications built with Apache Cordova or encroached web applications such as Twitter Lite.

It appears that Chrome 79 is related to changing the way web data is stored. When the device was updated to 79 Chrome, some (or all) local data was not displayed in web apps and webview apps. Chrome did not delete old data after migration. This data may still be intact, but it is now inaccessible.

Mobile devices such as Android phones and tablets rely on LocalStorage and WebSC sites to provide storage mechanisms. This allows a website or web application to store data on the user’s device inside the Chrome user’s profile directory.

Some Android app developers prefer to upload user data to a custom database server. However, some websites still use either locally or WebSQL. Many mobile application developers are used locally and use WebSQL stored locally on mobile devices.

In practice, many Android applications are typically a website loaded within the WebView component. This process works as a lighter version of Chrome. It is a simpler and more compact way to save user settings and data locally from an onboard SQLite database.

According to Google the most obvious solution to recover “deleted” data is to move the lost files to their new locations or to continue the change by moving the migrated files to their old locations. However, developers’ comments on the Chromium Bug forum do not fully support either of the two solutions. The most common opinion is waiting for this issue and hope that Google can solve all the problems. There is a quick fix released this week.
