The current generation of iPhone, iPod Touch, and pretty much all mobile devices max out at last generation 802.11g WiFi speeds. Could the next generation finally catch up? They'd need something that packed all that speed and range into a pretty tiny chip... Luckily, Engadget says such a chip is already becoming available:
Broadcom has announced its BCM4329, one of the first mobile 802.11n solutions on the block. On top of delivering up to 50Mbps of real-world WiFi throughput on both the 2.4GHz and 5GHz bands, the darned thing throws in Bluetooth, an FM receiver, and an FM transmitter, too -- in other words, everything but the kitchen sink, where the "kitchen sink" is the cellular radio itself.
Since TiPb is still predicting an iPhone HD for 2009, and 802.11n was part of that prediction (we'll need it to stream 800x480 video!), we'll just say it right now: yes please!
