★ A Tale of Two Modems

This article discusses Apple's reported plan to use both Qualcomm modems (for mmWave support) and its own C2 modem in different iPhone 18 Pro models, based on data from a Tata Electronics breach. It compares the trade-offs: Qualcomm modems offer faster mmWave 5G speeds, while Apple's modems are more power-efficient. The author shares personal experience testing LTE vs 5G speeds, concluding that for most users, the speed difference is negligible and battery life may be more important. The piece is tech-focused, covering mobile hardware, 5G technology, and Apple's chip strategy.
