Are those from Infineon->Intel->Apple modem lineage or is that a different team?

View on HN

I think the acquisition of the Intel modem group is too recent to have been integrated into the Apple watch

Why would they have not used them before the acquisition?

Apple Watch uses Intel IBIS or Qualcomm cellular modems depending on model (for those with cellular).

Wi-Fi/BT is handled separately by Apple-designed chips for the newer ones.

One of the recent phones (X or 11?) used Intel for part of its builds (as far as I remember you couldn’t tell from serial number). Apple had a lot of problems and swore off the Intel parts, which killed Intel’s wireless business.

I assumed Apple bought the Intel product line for IP, especially after that episode.

the iPhone 7 used the intel wireless chip. it was a major downgrade for me from my iPhone 6 at the time: speeds were lower for data transfers, and reception was less (could be attributed to an antenna change?)

overall, I was very happy to get a phone that didn't use the intel chips.

Apple used Intel modems for many generations - the iPhone 7, X/8, XS, 11. For some generations they used Qualcomm chips in the models for CDMA regions since Intel didn't make a CDMA modem. So you could tell which chip you'd get from the iPhone model number.

Apple ditched Intel due to Intel being at least a year behind on 5G.

These modems were all LTE modems though. They've always used separate Broadcom chips for WiFi/Bluetooth.

That's not the only thing Intel is at least a year behind on.

> "For some generations they used Qualcomm chips in the models for CDMA regions since Intel didn't make a CDMA modem."

Yeah. The Qualcomm-equipped international version of the iPhone X notoriously got significantly better LTE speeds compared to the Intel-modem version sold in UK/Europe.

>which killed Intel’s wireless business

I was under the impression that modern laptops ship with intel WiFi cards (I think I saw some Lenovo laptop use it). Do you mean it killed their modems ?

WiFi and cellphones are both wireless, but this discussion is about cellphones.

For Wi-Fi/BT, it's an Apple team separate from modem efforts.

I'll just leave this old 2012 article link here.
