While we're not big fans of proprietary standards, this is a good indication of the future: If you own one of several D-Link 802.11g products, you can now download the firmware upgrade that boosts the maximum speed among D-Link devices to 108 Mbps. (Really, it's Atheros under the hood that's providing this bump. We don't know if all Atheros-based G gear will interoperate at 108 Mbps, but it's likely.) Actual throughput? We don't know yet.
The 802.11n committee at the IEEE will be working on increasing the rated speed of wireless LANs and improving the net throughput. Real-world experiments like Atheros and D-Link's might provide data points, but they almost certainly won't increase market share. Most home users don't need 108 Mbps raw, and wouldn't have a good reason to use it. Business users wouldn't buy consumer gear, nor would they buy a proprietary solution that didn't have a guaranteed upgrade path.
Remember D-Link's previous chip vendor Texas Instruments's 802.11b+ (PBCC-based 22 Mbps)? Those chips can't be taken to 802.11g, and I doubt Atheros would guarantee that 802.11g + 108 Mbps could be brought up to 802.11n (nor should they make such a promise). [via eHomeUpgrade]
