Thread is Embedded in New iPad, MacBook, and iMac

Last autumn, Apple introduced Thread technology in the iPhone 15 Pro and Pro Max. Now, this wireless communication protocol has been secretly integrated into several new iMac and iPad models released since September 2023.

It's worth noting that the Thread technology radio modules in these devices might currently be inactive, and Apple has not mentioned this technology in its public communications. However, testing reports from the Federal Communications Commission (FCC) confirm that many newly released Apple devices have undergone Thread module compatibility testing.

Here are the specific models where Thread testing records were found:

• iPad Pro 13-inch (M4) (Wi-Fi + Cellular)

• iPad Pro 11-inch (M4) (Wi-Fi + Cellular)

• iPad Pro 11-inch (M4) (Wi-Fi)

• iPad Air 11-inch (M2) (Wi-Fi + Cellular)

• iPad Air 13-inch (M2) (Wi-Fi)

• MacBook Air 15-inch (M3)

• MacBook Pro 14-inch (M3)

• MacBook Pro 14-inch (M3 Pro or M3 Max)

• MacBook Pro 16-inch (M3 Pro or M3 Max)

• iMac (M3, two ports)

• iMac (M3, four ports)

  
  

According to FCC regulations, manufacturers must thoroughly list and test all wireless technologies in their products. Thus, even though Thread is not mentioned in the product specifications on Apple's website, it appears in the FCC reports linked to each device.

Tom Sciorilli, Director of the Thread Group Certification Committee, noted that the FCC report references FCC 15.247, which governs device transmission regulations. This report indicates that devices operating with Thread will generally stay within permitted ranges and not interfere with other radios. The testing mentioned in the report pertains to the IEEE 802.15.4 standard, which forms the basis of Thread technology. Although this standard also supports other technologies, the report specifically highlights Thread, focusing on its performance.

Thread is a new wireless communication protocol primarily used for connecting and communicating between smart home devices. It is one of the key wireless protocols for the Matter smart home standard, which aims to enable compatibility and collaboration between smart home devices from different brands and manufacturers.

HomePod mini is Apple's first product featuring Thread. Thread offers faster network speeds and broader coverage than Bluetooth, making it ideal for connecting smart home devices such as light bulbs, locks, thermostats, and sensors. Apple has been using Thread technology for several years, integrating it into its smart home platform. For instance, the HomePod Mini has supported Thread since 2020, and the second-generation HomePod and various Apple TV models also support this technology.

However, Apple has never publicly stated that its Mac or iPad products include Thread. This might be because Apple has enabled Thread in these devices but has not disclosed this information officially due to reasons such as confidentiality or technical considerations.

The inclusion of Thread in Mac and iPad could be because these devices run the Apple Home app. Thread allows them to communicate directly with smart home devices and act as border routers in the Thread network. This would enable Macs and iPads to become central hubs for smart home control, allowing users to manage their smart devices conveniently.

Apple’s announcement of Thread in the iPhone 15 Pro and Pro Max briefly mentioned the technology and suggested it opens up unlimited possibilities for the Home app. This could imply that Apple itself might not fully understand the reasons for incorporating this technology but chose to use Thread to ensure future compatibility.

Thread is a low-power, low-latency wireless protocol based on IP, widely used in smart home applications for connecting devices like smart bulbs, locks, and thermostats. However, its applications are not limited to smart homes; it can also connect devices like smartwatches, medical devices, fitness equipment, AirTags, keyboards, and mice to computers, smartphones, or iPads.

HooRii Technology, a pioneer of Thread technology in China, focuses on the development, testing, certification, and mass production of Matter over Thread products. With extensive experience in this field, HooRii Technology offers comprehensive Thread certification services, including consulting, testing, and transfer certification, to help developers and device manufacturers navigate the market entry process.

Although Apple is optimistic about Thread's future and views it as a key factor in development, its widespread application in practice remains to be seen. As more device manufacturers and products adopt Thread, we can expect more innovation and integration opportunities that will drive the advancement of smart home and other fields.
