NVIDIA's Tegra 4i appeared in February boasting, amongst other things, its built-in Cat. 3 LTE modem capable of speeds as high as 100Mbps. What NVIDIA didn't make obvious at the time was that the i500 modem, the fruit of its Icera acquisition, had the processing grunt to enable a software modem update to boost its speed to Cat. 4 LTE (150Mbps.) We had a quick visit with NVIDIA and saw a "perfect world demo" (pic above) of the device being bombarded at 150Mbps as well as placing an actual call on AT&T's network and streaming video. Of course LTE-Advanced doesn't exist in the real world yet, nor does a real handset sporting this chip, though seeing another player battling incumbent Qualcomm in this space before these networks have even been lit up certainly warms our hearts. Check the PR text for all the nitty gritty details after the break.
