So where do dual-mode chipsets come into play? On the client. In the future, you'll be able to purchase wireless NICs that support 11a, 11b and 11g simultaneously. Your client will connect to the access point that provides the best possible service, so you'll be able to roam transparently between access points at different frequencies. It's an appealing goal, indeed. But a number of security, performance and management issues must be resolved before this approach becomes practical.
In the meantime, it's good to see so many vendors jumping into the dual-mode chip market. At the very least, this will result in greater competition and lower prices for everyone.
