Apple has posted a second release candidate to developers. A release candidate, also known as “going silver,” is a beta version with potential to be a stable product.
Registered developers can download the beta via Apple’s developer portal. Or they can be downloaded over-the-air once the proper configuration profile has been installed from the Developer Center.
From the article: Apple has developed a software update and the ANFR has validated it since it effectively brings the localized “member” SAR into compliance with the regulatory limit of 4 W/kg. This update was distributed by Apple to certain voluntary customers over the past few days (“beta testers”). The company has committed to rolling out this software update to all French iPhone 12 users by October 24 at the latest.
iOS 17.1 is designed to allay ANFR fears over iPhone 12 radiation levels. On September 12, LeParisien reported that France’s National Frequency Agency notified Apple to withdraw its iPhone 12 from sale as it emits “too powerful waves.” If the American manufacturer didn’t comply, Jean-Noël Barrot, Minister in charge of Digital Affairs, threatened to go further, the article adds.
The ban was implemented after France’s radiation watchdog, Agence nationale des frequences (ANFR), did its own testing on the iPhone 12. Without revealing the testing methodology or the results, a French minister said that the iPhone 12 exceeded the country’s Specific Absorption Rate (SAR) for RF exposure.
SAR is a measure of the amount of radio frequency energy absorbed by the body when using a mobile phone. In the U.S., the FCC requires cell phone manufacturers to ensure that their phones comply with objective limits for safe exposure. Any cell phone at or below these SAR levels (that is, any phone legally sold in the U.S.) is a “safe” phone, as measured by these standards. The FCC limit for public exposure from cellular telephones is an SAR level of 1.6 watts per kilogram (1.6 W/kg).
The ANFR claims to have found absorption at 5.74 watts per kilogram for its testing on-contact. The European Union (EU) limit for on-contact exposure is 4 watts per kilogram.
However, as noted by AppleInsider, Apple’s testing conforms to an international industry standard. As Apple says, during testing, iPhone radios are set to highest transmission possible manually and SAR is evaluated in real time, over time intervals as specified by applicable regulations.
Still, on September 15 Apple said it would issue a software update for iPhone 12 users in France to address radiation concerns raised by the country’s regulators. Hence: iOS 17.1.
