iPhone 4G IV could support 802.11n


The next iPhone will have a Broadcom BCM4329 chip inside it, a low-power chip that supports 5GHz 802.11n networks. Basically, some dudes at AppleInsider (HA!) found resource files that point to drivers for the new chip is reserved for the next gen Touch and iPhone and should be able to offer higher quality of service.

The new device also focuses on efficient power management, with a special integrated PMU (power management unit) and a shared Bluetooth and WiFi receive signal path, which “eliminates the need for an external power splitter while maintaining excellent sensitivity for both Bluetooth and WLAN.”
