NVIDIA’s Tegra 4i Processor Shows Off 150Mbps LTE at CTIA 2013

Between the NVIDIA SHIELD, the company pledging support for the Xbox One, and now a successful tech demo at CTIA 2013 in Las Vegas, NVIDIA can’t keep themselves out of the news.

The Tegra 4i, NVIDIA’s mainstream mobile processor that includes a built-in i500 LTE modem, had a very successful showing this week, going through 150Mbps of LTE data. The processor was first shown at Mobile World Congress in February at Cat 3 100mbps, but has since gone through a software update. Nothing has been changed regarding the hardware.

Since the modem is designed with Deep Execution Processors, it’s forty percent smaller than traditional LTE modems. The modem is also multi-mode, offering 4G LTE Advanced while being backward compatible so that it can offer LTE Cat 3, 3G, and 2G, meaning that the modem will be effective even in areas where LTE networks aren’t available.

NVIDIA’s mobile processor for mainstream smartphones – Tegra 4i, which includes an integrated NVIDIA i500 LTE modem, chewed through 150Mbps of LTE data in a demo this week at CTIA 2013 in Las Vegas.

First shown at Mobile World Congress in February at Cat 3 100mbps, this Tegra 4i demo is fully based on a software update – no new hardware, no new processor. This showcases the adaptability and flexibility of NVIDIA’s software-defined radio technology.

Speed to Burn: Tegra 4i chewed through 150 Mbps of data in a demo at CTIA this week.

An additional advantage of the technology is its tiny size. 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 4G LTE Advanced and is backward compatible so it can offer LTE Cat 3, 3G, and 2G. That means it will work even where LTE networks aren’t available. Other LTE Advanced features will be coming soon in software.

The CTIA demo used a tester which emulates an LTE Cat 4 network because live local LTE Cat 4 networks don’t exist yet. In this demo Phoenix – the Tegra 4i reference smartphone – is connected to the tester and shows 150 Mbps.

We also demonstrated Phoenix running on a live AT&T LTE network – showing video streaming over LTE and voice calls. It’s a great proof point of our strong progress in Tegra 4i modem stability and performance.
