Earlier this week, NVIDIA demoed its new Tegra 4i that includes the new integrated NVIDIA i500 LTE modem - it managed to smash data speed records by pushing 150Mbps of data. This speed record showcases the power of NVIDIA's software defined radio by managing to upgrade the existing Cat 3 radio (100Mbps) to the Cat 4 radio only with a software update.
One major advantage is the radio's small size, as NVIDIA's Brian Del Rizzo pointed out in a press release. "Because the modem is designed with general purpose Deep Execution Processors (DXP), it's 40 percent the size of a conventional LTE modem. The benefit is a fast, high performance, adaptable modem in a tiny footprint."
Tegra 4i's modem is also multi-mode. It delivers not only 4G LTE Advanced, but is backward compatible so it can offer LTE Cat 3, 3G and 2G. Meaning that it will work even where LTE networks are not available. NVIDIA says that we can expect other LTE Advanced features based in software very soon.
