Apple iPhone 16e with C1 5G Modem Lacks mmWave Support, Falling Short Compared to Snapdragon X75 in iPhone 16

The long-awaited iPhone 16e has made its debut, featuring a significant innovation: Apple’s proprietary C1 5G modem. This custom-made modem is touted as the most efficient baseband chip that Apple has integrated into its iPhone lineup to date. While precise technical specifications are still pending, early analyses reveal that the C1 modem lacks support for mmWave networks. This absence stands in contrast to the Snapdragon X75 5G modem, which powers the entire iPhone 16 series and is known for its exceptional downlink and uplink performance.

Understanding the Limitations of the C1 5G Modem

In terms of network capabilities, Apple has been relatively tight-lipped about the C1 modem’s performance metrics. The primary selling point appears to be its energy efficiency and its ability to provide fast and dependable 5G connectivity. However, what remains unaddressed is the fact that the C1 modem does not support mmWave technology, which limits the potential for high-speed wireless performance that is available with competing modems like the Snapdragon X75. Consequently, consumers may find themselves at a disadvantage in terms of connectivity speed and reliability.

“Expanding the benefits of Apple silicon, C1 is the first modem designed by Apple and the most power-efficient modem ever on an iPhone, delivering fast and reliable 5G cellular connectivity. Apple silicon — including C1 — the all-new internal design, and the advanced power management of iOS 18 all contribute to extraordinary battery life.”

It is essential to note that integrating mmWave support involves more than simply adding another chipset to the device. It requires a meticulous approach to smartphone design, including optimal placement of antenna bands to achieve maximum throughput. This process is complex and necessitates extensive testing to ensure both reliability and enhanced performance.

Another factor contributing to Apple’s decision to forgo mmWave support may be the limited deployment of this technology in numerous regions, primarily due to the extensive infrastructure upgrades that carriers must undertake. As the anticipated 22 million shipments of the iPhone 16e are expected to predominantly originate from developing markets, Apple may have concluded that the investment in mmWave technology would not yield a favorable return, especially considering the potential increase in production costs. As the company has refrained from providing performance benchmarks for the C1 modem, consumers will need to await comprehensive test results for a clearer understanding of its performance.
