Which is about what I get with T-mobile HSPA+. Low latency is why T-mobile "4g" is superior to Sprint 4g Wimax.
FWIW, this isn't WiMax, this is LTE.
As far as latency, I left it out of my post, but latency has basically two parts- the latency of the wireless technology and then the latency of the back-end connection once you get to the tower.
I remember travelling in Poland two years, I had a latency of about 160ms using EDGE - the same EDGE technology that gave me about 400ms of latency on T-Mobile in the US. Latency is strongly dependent on the carriers back-end implementation and routing.
I would most definitely not take rumors about LTE latency on a prototype non-production system as a basis conclude that production HSPA+ on T-Mobile is superior to either WiMax or LTE. On paper, this is totally not the case and companies aren't totally stupid.

HSPA+ is a lot cheaper to roll out than LTE or WiMax, and companies would stick with HSPA+ if it was really superior.
