For example, the bandwidth between 3 GHz and 4 GHz is 1 GHz.  The bandwidth of an 802.11 channel is 22 MHz.&lt;p&gt;Obviously it&apos;s a lost cause trying to stop everyone from using &quot;bandwidth&quot; to mean throughput or a data rate.  Don&apos;t get me started on people using bandwidth to mean how much work they can handle either: &quot;I don&apos;t have the bandwidth to handle another project, you better give it to somebody else.&quot;&lt;p&gt;&amp;#60;/useless but informative gripe&amp;#62;</text></comment>

He says that it&apos;s 1500 minus the packet overhead, but I&apos;ve always seen MTU as 1492 (I could be recalling incorrectly here). In any case, MTU changes as you travel over various networks with various settings, using various technologies (ethernet,wireless,fiber,etc).</text></comment>
