<p align="center"> </p><p><p> Yesterday we stopped by Broadcom to look at their newly announced BCM21892 LTE baseband, which we saw teased previously at CES doing a VoLTE call. If you're not famliar with the details of Broadcom's first LTE baseband, it's a 3GPP Release 10 modem supporting all the 3GPP air interfaces (GSM/EDGE, WCDMA, TD-SCDMA, LTE) with Category 4 LTE support, support for 10+10 MHz carrier aggregation, integrated 8 port transceiver into the baseband package, and built on a 28nm HPm process.</p> <div align="center"> <table align="center" border="0" cellpadding="0" cellspacing="1" width="590"> <tbody> <tr class="tgrey"> <td align="center" colspan="5"> Broadcom's LTE Baseband</td> </tr> <tr class="tlblue"> <td width="120"> </td> <td align="center" valign="middle"> BCM21892</td> </tr> <tr> <td class="tlgrey"> Air Interfaces</td> <td align="center" class="text" valign="middle"> GSM/EDGE, WCDMA, LTE-A, TD-SCDMA</td> </tr> <tr> <td class="tlgrey"> 3GPP Release</td> <td align="center" class="text" valign="middle"> Rel. 10 (LTE-A)</td> </tr> <tr> <td class="tlgrey"> HSPA+ Category</td> <td align="center" class="text" valign="middle"> Cat. 24, DC-HSPA+ 42.2 Mbps</td> </tr> <tr> <td class="tlgrey"> LTE</td> <td align="center" class="text" valign="middle"> Cat. 4, LTE-A 150 Mbps Downlink / 50 Mbps Uplink

I recorded a video of the entire demo walkthrough which I'd encourage you to watch if you're interested. The booth contained both BCM21892 working on a few demo boards, as well as integrated with their own platform form factor reference design which runs the full house of Broadcom silicon - WLAN/BT Combo, SoC, and GPS. </p> <div align="center"> <iframe allowfullscreen="" frameborder="0" height="315" src="http://www.youtube.com/embed/yG5g14xyBL4?rel=0" width="560"></iframe></div> <p> Broadcom demonstrated both full 150 Mbps UE Category 4 rates on a cabled up demo, 10 + 10 MHz carrier aggregation on Band 17 and 4 (AT&T's configuration) switching in and out the band 4 carrier, and envelope tracking support working on the BCM21892. </p> <p> <div>Gallery: A Look at Broadcom's BCM21892 LTE Baseband at MWC<div>      </div></div></p> </p> <div class='mf-viral'><table border='0'><tr><td valign='middle'> </td><td valign='middle'> </td></tr></table></div><br/><br/>
