Apple is looking to start work on sixth-generation (6G) cellular connectivity, indicating it wants to be a leader in the technology rather than relying on other companies.

Apple has launched its first iPhones with 5G wireless speeds just a few months ago.

The California-based company has posted job ads this week seeking wireless system research engineers for current and next-generation networks. The listings are for positions at Apple’s offices in Silicon Valley and San Diego, where the company works on wireless technology development and chip design.

“You will have the unique and rewarding opportunity to craft next generation wireless technology that will have deep impact on future Apple products,” according to the job announcement.

People hired for the positions will “research and design next generation [6G] wireless communication systems for radio access networks” and “participate in industry/academic forums passionate about 6G technology”.

Industry watchers don’t expect 6G to roll out until about 2030, but the job listings indicate Apple wants to be involved at the earliest stages in the development of the new technology.

Though Apple is laying the groundwork to be a key player in 6G, it has much work ahead to take full advantage of 5G, a technology in its infancy.

The company hasn’t expanded 5G to other devices like the Apple Watch and iPad, and it sells multiple iPhones that use older 4G technology. It’s likely that Apple’s first modem will be for 5G connectivity.
