I think it was decent attempt of Intel to conquer mobile market and get rid of 3GPP gang. The whole thing was standardized in IEEE and architecture was much simpler than what we have today. I think technology had a decent chance to win but vendor politics killed it. Even if you’re Intel - sometimes you’re not big enough to move the market.
Intel thought they had a lot more power in the telco space than they did based on their position in the PC space. I wrote a research note to that effect and they were not happy.
I didn’t quite stake my career on it but working as embedded/network dev it was three years of my life. It was fun and I learned a ton of stuff about L2 that I almost never had to use and L3-4 that I still use frequently
