Apple's work on communications satellites and next-generation wireless technology means the aim is likely to beam data to a user's device, potentially mitigating the dependence on wireless carriers, or for linking devices together without a traditional network. Apple could also be exploring satellites for more precise location tracking for its devices, enabling improved maps and new features.

Amazon.com plans to deploy more than 3,000 satellites as part of a future constellation. However, the industry is littered with failures. Iridium filed for bankruptcy protection in 1999, and Teledesic abandoned its “Internet from the sky” plan more than a decade ago. Newer efforts from Facebook, SpaceX and Amazon are a long way from generating revenue, and Apple rarely enters new categories without a clear way to make money.

In recent months, Apple has started hiring new software and hardware experts for the team, seeking engineers with experience in designing components for communications equipment. The company has also hired additional executives from the aerospace and wireless data delivery fields.

As Bloomberg has previously reported, Apple also is working on a virtual reality headset to debut as early as 2021, augmented reality glasses for launch after that, MicroLED screens for future devices, new home products, self-driving car technology and a future Apple Watch that can analyze a user's blood chemistry to determine glucose levels. 

Apple is also expanding its in-house chip development, seeking to replace Intel as its Mac processor maker, and Intel and Qualcomm as the providers of its modem component for phones.
