Begin with reading about the simple CDMA protocol given in the textbook, and then study more advanced CDMA schemes from other sources, including the Internet.

The network layer to be studied in this and the next unit provides host-to-host communication services to process-to-process communication services. It is the network layer that makes data flow correctly and efficiently across the entire Internet. This network layer is so important in the TCP/IP network protocol stack that it is studied over the course of two units. Unit 4 deals with the data plane of the network layer and illustrates how a transport layer segment is packed into packets for transmission from origin to destination. Unit 4 also covers IP forwarding, a basic function that every host and router on a network must have.</p> +</div> +<div class="col-12"><footer><!-- <p>© [Client] [Year]</p> --> <!-- <p><img src="/shared/LCS_HTML_Templates/Athabasca_Template_2021/_assets/img/logo.png" alt="logo"></p> --></footer></div> +</div> +</div> +<p> +<script src="/shared/LCS_HTML_Templates/Athabasca_Template_2021/Template_Files/sample_pages/../../_assets/thirdpartylib/jquery/jquery-3.4.1.min.js"> + </script> +<script src="/shared/LCS_HTML_Templates/Athabasca_Template_2021/Template_Files/sample_pages/../../_assets/thirdpartylib/popper-js/popper.min.js"> + </script> +<script src="/shared/LCS_HTML_Templates/Athabasca_Template_2021/Template_Files/sample_pages/../../_assets/thirdpartylib/bootstrap-4.3.1/js/bootstrap.min.js"> + </script> +</p> +<!-- Template JavaScript --> +<p> +<script src="/shared/LCS_HTML_Templates/Athabasca_Template_2021/Template_Files/sample_pages/../../_assets/js/scripts.min.js"></script> +<script src="/shared/LCS_HTML_Templates/Athabasca_Template_2021/Template_Files/sample_pages/../../_assets/js/custom.js"></script> +</p></body></html>
