A mysterious discovery has been unearthed inside the new iPod Touch.
According to the San Franciso Chronicle (http://www.sfgate.com/cgi-bin/article.cgi?f=/g/a/2009/09/11/urnidgns852573C4006938800025762F0015B121.DTL), a Broadcom Wi-Fi chip was discovered during the dissection of the new 32GB iPod Touch by the makers of iFixit, a Web site (http://modmyi.com/forums/#) founded six years ago to help people "tinker with their electronics."
The new Apple iPod Touch uses a Wi-Fi chip that can support the just-approved high-throughput 802.11n standard, though Apple apparently has not switched on the cranked-up wireless (http://modmyi.com/forums/#)link. If it does, the iPod Touch (which is almost identical to the iPhone but lacks the 3G cellular radio) could support a 50Mbps data rate, more than twice that of the current 802.11ag radios used by the product family.The single chip combines 802.11n with 802.11abg,Bluetooth (http://modmyi.com/forums/#), and FM radio. It runs in both the 2.4 GHz and 5 GHz bands. The chip reflects the range of implementations available to chip and equipment vendors. The 802.11n technology exploits multiple-input multiple-output splitting a high-rate data stream into, today, two slower streams, each sent from and to a corresponding pair of antennas. It creates a kind of parallel transceiving capability, which dramatically multiplies 11n's capacity.Although the discovery of the chip inside the iPod Touch was surprising, Apple's use of the chip isn't - they've been employing 11n in their desktop (http://modmyi.com/forums/#)products since 2007.
We don't know yet if 802.11n will be supported in the iPod Touch software, but at least the hardware's there. Article from modmyi
