Nvidia updates modem in Tegra 4i, adds LTE-Advanced connectivity
Nvidia has updated its latest mobile chipset with support for Category 4 LTE connectivity. <a href="" rel='nofollow'>Tegra 4i</a>, similar to Tegra 4 but includes an integrated Nvidia i500 LTE modem, managed to upgrade from Category 3 and its 100Mbps connection to <a href="" rel='nofollow'>LTE-Advanced</a> and a possible 150Mps speed, without performing any changes to the hardware. <br />
<br />
The upgrade was accomplished with changes in software alone. The i500 LTE modem is a software-defined radio that uses Deep Execution Processors, and so was able to be changed without altering anything to it or Tegra 4i at all physically. The use of a software-defined modem also allows it to take up far less space in the chipset itself, allowing more room for other components. <br />
<br />
Demonstrations at the <a href="" rel='nofollow'>CTIA</a> event in Las Vegas shows Tegra 4i working on an LTE-Advanced network at 150Mbps, though emulated due to the lack of live networks using such Category 4 connections. The Phoenix Tegra 4i smartphone is also being demonstrated on a live <a href=" aluma/" rel='nofollow'>AT&T LTE</a> network, in order to show off the performance and stability of the software modem when used for voice calls and video streaming.
