The only way for Wi-Fi chip makers to survive is to integrate their chips with other functions: At least that's the conclusion of an editor with EE Times. He suggests that the chipmakers that have tried to set themselves apart from the rest by improving the performance of their chips haven't been successful. But those that integrate functions such as DSL into a Wi-Fi chip will add value, appeal to a certain market and avoid the "massacre" in the Wi-Fi chip market.
It's a good theory, seeing as chipmakers have been killing themselves trying to offer the best power savings and coverage boost. They may be better off tying in other functions in order to differentiate themselves.
