iPhone 12, 12 Pro and 12 mini support mmWave 5G, but only in the US [u]

Apple’s latest iPhone 12 models are the first to feature 5G connectivity, but access to ultra-fast mmWave bands are limited to customers in the U.S.

Support for speedy 5G connectivity was a central selling point when Apple announced the new handsets on Tuesday. According to a support document, however, access to bands that offer the greatest data transfer potential are limited to certain models.

As noted by Apple, iPhone 12, iPhone 12 Pro, iPhone 12 Pro Max and iPhone mini integrate Qualcomm radios compatible with the n260 and n261 bands, which operate at 39GHz and 28GHz, respectively. Known as mmWave, these high-frequency bands feature wavelengths that can be measured in millimeters instead of centimeters or larger, and provide ample data transfer capability with bandwidths exceeding 3GHz.

While Apple’s 5G-compatible iPhones support a wide range of bands, including those that operate in the robust sub-6GHz spectrum, mmWave is restricted to U.S. models.

Apple says it “had to do things a little differently” to enable 5G communication on iPhone, like engineering custom antennas and radio parts.

“Then we gave iPhone 12 Pro the most 5G bands of any smartphone, so you’ll get 5G in more places,” the company says on its website.

On the software side, Apple optimized its software stack to take full advantage of 5G’s speed while maximizing efficiency. The company claims “many apps” will net 5G gains without drawing additional power.

Apple is jumping on the 5G bandwagon, but is doing so in a typically slow and steady way. Sensitive to the immense power draw required to make 5G work, the company is implementing smart algorithms to enable the hungry radios only when needed.

Whether mmWave compatibility will extend to countries beyond the U.S. remains to be seen, but that is a distinct

Best Prime Day 2020 headphone deals: Save $100 on Bose QuietComfort 35 II, $50 on AirPods Pro and more

Amazon Prime Day 2020 is officially here and runs through Wednesday, Oct. 14. Between Amazon’s hefty savings and similar sales from Walmart and Best Buy, now is a great time to be on the hunt for any type of headphones, from wireless ear buds to epic over-the-ear noise cancelling headsets with comfy ear cups.. 

So far, we’re seeing deep discounts on Sony headphones that we’ve traditionally seen around Black Friday and Cyber Monday. Sony has lowered prices on last year’s WF-1000XM3, as well as the newer WF-SP800N, which is water-resistant and features noise cancellation. The entry-level WF-XB700 Extra Bass is at the lowest price we’ve ever seen, $78. We’re also seeing Apple headphones return to a low price of $199 (even as a new AirPods Studio over-ear headphone remains rumored). 

We expect to see more amazing headphone discounts throughout Tuesday and Wednesday, so if you’re in the market for a specific type of headphone, say ones with Bluetooth connectivity, noise cancellation or true wireless earbuds, keep checking back.

Note that you’ll need to be an Amazon Prime member to get these exclusive deals.

New iPhones were unveiled Tuesday, and they will come without wired headphones in the box for the first time ever. In the meantime, Apple’s current top of the line noise-canceling true wireless headphones are now back to selling at $199. That’s still pricey, but it’s $50 off what you’ll pay at the Apple Store, and $20 less than their usual price at Amazon.

HITACHI Rail STS Chooses AdaCore’s GNAT Pro Software Development Environment for New Rail Safety Platform

AdaCore, a trusted provider of software development and verification tools, today announced that HITACHI Rail STS (Signaling and Transportation Systems) has selected AdaCore’s GNAT Pro Ada development environment targeting ARM processors for the modernization of its CSD (Calculator of Available Safety) rail safety platform, to ensure the safe circulation of trains on railway lines and metro networks.

Technical challenges of modernization
In March 2017, HITACHI Rail STS rolled out the interlocking management system of the Gare de Lyon in Paris as part of a renovation project commissioned by the French national rail company SNCF. The system, supported by a single safety platform, commands 170 switches, 115 light signals and 800 routes at any time and simultaneously, and thus requires a secure, reliable platform.

In 2018, facing the problem of obsolete equipment and the need for ever greater computing power, HITACHI Rail STS decided to further modernize its safety platform with the ambitious goal of developing a single platform that is also compatible with the constraints of rolling stock and ground signalling.

The first targets were the renovation of the metro lines in the city of Brussels with a Communication Based Train Control (CBTC) system, and the renovation of the interlocking systems of the first 280 mile-long high-speed rail line in France between Paris and Lyon.

HITACHI Rail STS identified 2 key areas of focus in order to achieve its goal:

  1. Conduct logic synthesis on the 68K CPU in order to house the “voter” function of the CSD in the Processing System part of this component, thus making it possible to reuse the coded monoprocessor production chain of the existing voter software,

  2. Port the existing application software, developed in Ada 95, to
