Walked around downtown Seattle this afternoon testing 4g speeds. The bad news is it averaged a little over 2 mbs download, less than 1 up. The good news is good 3g only produced about .5 down, and about the same up, so 4g tested a lot better. By comparison, by home WiFi gives me >8 down, and about 2.5 up. 4g varied between 1-3 bars. Any suggestions how things might be speeded up? Did not have on GPS, WiFi when testing 4g. There are a lot of tall building where I was walking, but had more consistent results up on the 37th floor of one of the office buildings; still never more than 2.6 download.
