Core Viewpoint - Apple is transitioning to in-house modem chips, starting with the C1 modem in the iPhone 16e, aiming to replace Qualcomm and eventually control all network functionalities internally [1][3]. Group 1: C1 Modem Introduction - The C1 modem debuted in the iPhone 16e, focusing on efficiency but lacking support for 5G millimeter wave and all wavelengths of existing Qualcomm modems [3]. - The C1 modem is described as the most power-efficient modem on an iPhone, providing fast and reliable 5G connectivity [3]. Group 2: Future Modem Developments - The C2 modem, codenamed Ganymede, is expected to launch in the iPhone 18 series in 2026, featuring mmWave support and download speeds of 6 Gbps [3]. - The C3 modem, codenamed Prometheus, is planned for release with the iPhone 19 series in 2027, aiming to surpass Qualcomm's performance and support next-generation satellite networks [4]. Group 3: Network Chip Developments - Apple is also working on a new network chip, codenamed Proxima, to replace Broadcom's chips, expected to debut in HomePod mini and Apple TV updates later this year [6]. - This new chip will support Wi-Fi 6E and is anticipated to enhance connectivity between Apple devices while reducing costs [6]. Group 4: Integration Plans - After the modem transition, Apple is considering integrating its cellular modem into the main Apple Silicon chip, which could bring cost and efficiency benefits [7].

Core Viewpoint - Apple is transitioning from Qualcomm to its own modem technology, starting with the C1 modem in the iPhone 16e, aiming for complete internal processing of network functions in the future [1][3]. Modem Development - The C1 modem debuted in the iPhone 16e, focusing on efficiency but lacking support for 5G mmWave and all wavelengths of existing Qualcomm modems. It is described as the "most energy-efficient modem on iPhone" [3]. - The C2 modem, codenamed Ganymede, is expected to launch in the iPhone 18 series in 2026, featuring mmWave support and download speeds of 6 Gigabits per second [3]. - The C3 modem, codenamed Prometheus, is planned for release alongside the iPhone 19 series in 2027, aiming to surpass Qualcomm's performance and support next-generation satellite networks [4]. Networking Chips - Apple is also working on replacing Broadcom's networking chips, with a new chip codenamed Proxima expected to debut in updated versions of HomePod mini and Apple TV later this year, supporting Wi-Fi 6E [6]. - This new networking chip is anticipated to enhance connectivity between Apple devices and reduce costs [7]. Integration Plans - After the modem transition, Apple is considering integrating its cellular modem into the main Apple Silicon chip, which could provide cost and efficiency benefits, although this is projected to be realized by 2028 [9].
