Japanese network equipment supplier releases products using Airgo’s MIMO chips: The products will be sold across Asia and Europe, which must be a challenge given the variety of regulatory frameworks into which MIMO must fit. My understanding is that Airgo’s implementation generally toes the line with its 1st and 2nd generation chipsets. This release omits a mention of the 3rd generation silicon in describing these MIMO products. The 3rd gen chips have a dynamic option for 40 MHz wide channels instead of 802.11a/b/g’s standard 20 MHz channels. These wider channels aren’t uniformly allowed everywhere that Wi-Fi is approved. This is an issue for 802.11n, too, if they were to require a mandatory 40 MHz encoding, although channel selection has been solved through country-specific settings for virtually all Wi-Fi products.
