<p>The LTE Layer 2 software consists of the comprehensive implementation of the LTE MAC, RLC and PDCP protocol sub-layers. Features include:</p>
<p>&nbsp;</p>
<p><strong><u>MAC &ndash; All LTE transport channels with optional MBMS</u></strong>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<a onclick=&quot;showhidesani(&#039;myidone&#039;)&quot; href=&quot;javascript:void(0)&quot;>read more..</a></p>

<p><strong><u>                               PDCP &ndash; Ciphering, integrity protection and ROHC v1 (With an upgrade path to ROHC v2)</u>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<a onclick=&quot;showhidesani(&#039;myidthree&#039;)&quot; href=&quot;javascript:void(0)&quot;>read more..</a></strong></p>
<div id=&quot;myidthree&quot; style=&quot;display: none;&quot;>
<p>&nbsp;&nbsp; - &nbsp;Transfer of user data from NAS to RLC and vice versa</p>
<p>&nbsp;&nbsp; - &nbsp;In-sequence delivery of upper layer PDUs at handover for RLC AM</p>
<p>&nbsp;&nbsp; - &nbsp;Duplicate detection of lower layer SDUs at handover for RLC AM</p>
<p>&nbsp;&nbsp; - &nbsp;Retransmission of PDCP SDUs at handover for RLC AM</p>
<p>&nbsp;&nbsp; - &nbsp;Header compression and decompression to improve transmission for latency<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; sensitive data eg. VoIP and video conferencing</p>
<p>&nbsp;&nbsp; - &nbsp;Ciphering functionality for security</p>
