NVIDIA first announced the i500 LTE modem as part of the Tegra 4i at Mobile World Congress in February. The company has shown off an updated demo at CTIA 2013 in Las Vegas this week, featuring a new software update. The latest update allows the modem to reach speeds of 150Mbps, an increase from the MWC demo of 100Mbps. The combination of software-defined radio technology and Deep Execution Processors allowed NVIDIA to increase the performance without the need of new hardware, showing the potential for further upgrades as the software development proceeds.
