NVIDIA has really stepped up and made some great innovations for Android as a whole, and they’re not showing any signs of slowing down. The latest from the graphics chip maker is a demo of their Tegra 4i, which is the version of the Tegra 4 designed to be run in smartphones, complete with LTE modem. When the chip was first debuted, it was capable of reaching 100 mbps download speeds, which is considered CAT 3 speeds. (Most ethernet cables you probably use in your homes are CAT 5 cables, for reference)
Well, fast forward a few months, and NVIDIA has introduced a software update for the 4i that bumps up the down speeds of the modem to reach 150 mbps, which is considered CAT 4. The impressive thing here is that no new hardware was introduced; NVIDIA software-defined radio tech is running the show here. So not only can this processor’s modem reach speeds higher than what’s even available in the world today, but it can be made faster through software tweaks instead of adding hardware and is only 40% of the size of other LTE modems in use today. Watch out, Qualcomm.
