At CTIA 2013 in Las Vegas this week, Nvidia demoed the Tegra 4i, a mobile processor for mainstream smartphones. The 4i includes an integrated NVIDIA i500 LTE modem, which blew through 150Mbps of LTE data in a demo during the event.
The amazing thing about the Tegra 4i demo is that it is fully based on a software update – no new hardware, no new processor. That’s incredibly impressive, showing off the adaptability and flexibility of NVIDIA’s software-defined radio technology. The i500 LTE modem and NVIDIA Tegra® 4i’s processor (which uses an integrated i500 modem) use a revolutionary new software defined radio technology that supports the latest wireless protocols such as DC-HSPA+ and LTE, and also has the flexibility of being fully programmable to support next generation interfaces and standards. The NVIDIA i500 has a smaller die size, consumes lower power and offers greater implementation flexibility compared to competing LTE modems. Unlike conventional modems, the software reconfigurability of the i500 soft-modem makes it easy for carriers and OEMs to update modem features and to take advantage of performance-improving algorithmic innovations in the field through over-the-air updates.
Because of its size (40% of a conventional LTE modem), it brings high performance with great adaptability and many modes. Not only is it 4G LTE Advanced, but the modem also supports LTE Cat 3, 3G, and 2G, working perfectly where LTE is not available.
Nvidia is leading the charge when it comes to mobile processor technology, showing off great progress in Tegra 4i modem stability and performance.
