iPhones won’t come with headphones or power adapters in the box from now on

That drawer full of bad headphones and extra power adapters for your phone won’t get any more cluttered if you decide to pick up a new iPhone 12. Apple will no longer include those items in the box, part of a redoubled effort to reduce its environmental footprint.

In a segment of its iPhone-centric event today, Apple’s Lisa Jackson explained that the company is hoping to have “net zero climate impact” globally by 2030, meaning everything from manufacturing and assembly to packaging and device recycling will be carbon neutral. Achieving that means relying more on solar power and efficient operations, of course, but also reducing waste.

To that end the company will no longer include the familiar white headphones that have come in the box since the early days of the iPhone, nor the standard outlet adapter for the power cable.

“Customers already have over 700 million Lightning headphones, and many customers have moved to a wireless experience,” said Jackson. “There are also over 2 billion Apple power adapters out in the world, and that’s not counting the billions of third party adapters.”

Thankfully there will be a power cable in the box: a standard USB-C to Lightning cable that you can plug into your old wall adapter or a laptop. Well, not the old old ones, but the fairly recent ones. To be honest, you might need a dongle.

The result is not just fewer things in the box, but a smaller actual box, letting the company fit more of them into a pallet. That may sound like a bit of a stretch for effect — “really, you’re saving the world by making the box smaller?” — but at the scales Apple operates at, fitting half again as many devices into a shipment means saving thousands of trips. It’s

Apple may stop shipping power adapters with iPhone SE, other current devices

Apple is expected to ship new “iPhone 12” models without an AC power adapter, but it could also do the same for previously released devices like the iPhone SE.

The lack of a charging brick in the box is said to be a cost-saving move for this year’s iPhone models. Apple also stopped shipping power adapters with the Apple Watch Series 6, citing environmental reasons.

In a tweet on Tuesday, Bloomberg’s Mark Gurman suggested that the Cupertino tech giant would also stop shipping charging bricks with previously released iPhone models that “it’ll keep selling.”

Although Gurman doesn’t specify, his prediction suggests that Apple will — or already has — change the packaging for current iPhone models to reflect the absence of the charging accessory.

The Bloomberg reporter specified that Apple would nix the power adapter for the iPhone SE, as well as other pre-“iPhone 12” models that it’ll continue selling as part of its updated lineup. At this point, it isn’t clear which current iPhone models will continue to be sold alongside the updated “iPhone 12” lineup besides the iPhone SE.

Additionally, it’s unclear if Gurman’s prediction is simply a guess or actually based on actual leaked information. Gurman didn’t say whether he received the idea from an outside source.

Apple has long been rumored to be pivoting toward wireless charging for its flagship iPhone devices, and analyst Ming-Chi Kuo has forecast that the company could switch to a “completely wireless experience” by 2021. Apple is also rumored to be developing some type of small wireless charging adapter in lieu of AirPower.

Nokia Software to Power Telefonica UK Network, 5G Services

Nokia Corporation NOK recently secured a prime contract from Telefónica, S.A.’s TEF U.K. subsidiary to support the latter’s existing network connectivity as it transitions to cloud architecture. The contract for undisclosed amount also aims to facilitate rendering reliable 5G services to more than 34.1 million customers of the carrier.

In particular, Nokia will deploy its cloud-native Subscriber Data Management (SDM) software to centralize user data into a single, robust and secure User Data Repository. This central register with single point of provisioning will save operating costs and significantly speed up time to market while offering unrivalled scaling capabilities to meet the most stringent requirements. Notably, the SDM software serves approximately 4.8 billion global subscribers and devices, streamlining operations and optimizing services to improve efficiency levels.    

Per the deal, Nokia will support subscriber data management for the carrier’s 3G, 4G, 5G networks, along with Voice over LTE (VoLTE), Voice over WiFi (VoWiFi) and Voice over 5G (Vo5G) services. In addition, it will deploy Shared Data Layer, a cloud-native database accessible via industry standard protocols, to enable an open ecosystem and the integration of third party applications.

A few days back, Telefonica inked agreements with Nordic firms – Nokia and Ericsson ERIC – to provide essential telecommunications equipment for the nationwide deployment in Spain. Markedly, Nokia has been Telefonica’s preferred vendor since 2018 and has supported its 5G strategy with trials in the historical city of Segovia in central Spain. To its credit, Nokia is reportedly the only vendor to supply 5G radio technology to all of Telefonica’s 5G operations across Europe.

Nokia is well positioned for the ongoing technology cycle given the strength of its end-to-end portfolio. The company’s deal win rate is encouraging with notable successes in the key 5G markets of the United States and China. 5G revenues are

Huawei’s Four Open Source Basic Software Projects Infuse Diversified Computing Power into Every Line of Code

Four Basic Software Projects Power Innovation of Open Source Communities

While hardware provides the foundation of computing power, basic software helps unleash the potential, and application software creates tangible value for end users. Innovation will gain speeds when a virtuous cycle is formed among hardware vendors, basic software vendors, application software vendors, system developers, software developers, and users.

Open source software is an important part of Huawei’s computing ecosystem strategy. Huawei values open hardware, open source software, and partner enablement. By leading open source initiatives, contributing, and enabling business partners, Huawei supports the technical software ecosystem with continuous innovation.

In terms of community contributions, Huawei ranks No. 2 globally in the latest Linux Kernel 5.8 release. Huawei leads four open source projects: openEuler, openGauss, openLooKeng, and MindSpore, and has completed continuous integration with more than 40 mainstream communities. By contributing to upstream communities for mainstream scenarios, Huawei enables 80% of key communities to provide native support for Kunpeng. In this way, ARM developers can use these open source components easily. Such efforts all help to lay a solid groundwork for full-stack hardware and software collaboration.

Hardware is the basis of the entire ecosystem, and operating systems are the basis of software. openEuler officially went open source on December 31, 2019, and the 20.03 Long-Term Support (LTS) version was released in March 2020. After nine months of operation, the openEuler community has attracted more than 2000 contributors, set up 70 special interest groups (SIGs), and engaged more than 60 leading enterprises in China. Six top operating system vendors in China have joined the community and released commercial versions.

The innovation version, openEuler 20.09, will also be officially released on September 30, 2020. The release features 1+8: one kernel plus eight innovation projects, covering multi-core acceleration, iSula2.0 lightweight

Keysight Technologies and ROHM Semiconductor Enable Designers to Rapidly Modify SMPS Reference Design for SiC Power Devices

“Digital Twin” of ROHM Reference Design Enables “What if…” Design Space Exploration

Keysight Technologies, Inc. (NYSE: KEYS), a leading technology company that helps enterprises, service providers and governments accelerate innovation to connect and secure the world, and ROHM Semiconductor, a leading semiconductor company, jointly announce today a PathWave Advanced Design System (ADS)-compatible workspace that enables designers to perform pre-compliance testing on virtual prototypes of switched-mode power supply (SMPS) designs. This new capability saves time and cost by catching errors early in the design before they become a big problem.

Demand for SMPS is driven by the need for greater efficiency, increased power density and lower cost. Fast, low-loss switches made from silicon carbide (SiC) and related materials will power future applications due to the high performance and efficiency they enable. However, unwanted side effects from high-speed switching include voltage spikes (“ringing”). In addition, it is more difficult to meet conducted and radiated electromagnetic interference (EMI) specifications in higher speed designs. Pre-compliance analysis of a “virtual prototype” or “digital twin” is ideal for managing this challenge, but previously required expertise to build and use the necessary design information, called a “workspace.”

To address this, Keysight teamed with ROHM to create the “twin” of ROHM’s reference design (model P01SCT2080KE-EVK-001) available to mutual customers via Keysight’s web site at https://www.keysight.com/us/en/assets/3120-1476/application-notes/Virtual-Reference-Design.pdf.

Virtual prototypes are complementary to physical prototypes. Physical prototypes are the gold standard for compliance and measured characteristics, but have several drawbacks including: expensive and time consuming to design, build and measure; are vulnerable to catastrophic failure (the infamous “smoke test” that produces actual smoke); and it is hard to get a measurement probe onto interior nodes.

In contrast, virtual prototypes are easy to change and while they do flag device overstress as warning messages during simulation, they never emit real
