I think the issue is less can you hit 50+Mbps and low latency with a wireless connection and more can you maintain a consistent 50+Mbps and low latency with a wireless connection. At least that's the problem I've found playing against people who rely on a wireless connection. There are too many variables in the environment that can affect the consistency of their signal. I typically try avoid wireless opponents when gaming. Whether it be on console or gaming rig, I've found a better experience with wired opponents. Never Forza in a lobby with wireless guys unless you want to spend the race watching cars "Aladdin" the entire time.
Bingo. Wireless is typically too inconsistent for gaming.
