How fast are the sprint broadband wireless internet phone cards?

I use them regularly for internet access while on my train commute between Philadelphia and D.C. it is much faster than dial up but slower than 802.11 wifi or a LAN. You are able to stream audio and video though and I am able to maintain a connection on the entire trip from Philly to DC (except for in the tunnels)
