The title is somewhat misleading. Intel developed a "processor" (digital chip) to handle WiFi. The title implies that the chip + antennas are integrated within the CPU.
Sure, in the future the digital chip may end up being integrated, but this isn't major news, in my opinion.
Are you sure? Because if you were right, I don't think Intel would use money and resources to make a big announcement that they have caught up with technology that has been around for 13 years. From all other news and PR releases I've read, the wifi transceiver is integrated on the intel cpu dye. I believe you still need an antenna, but at these frequencies those are quite small (3mmx3mm inverted f).
That's exactly what they did. That's what SOC means. Basically instead of having to have a separate chip on the board for the radio, it's within the processor. Of course the board still needs an antenna, but this is just another step towards x86 cell phones.
