 <p>The equipment provides an ethernet interface at each end and has a comprehensive management system, shown in the attached screen shots. Measured throughput is 30Mb/s the configuration I&rsquo;m using is a 20MHz channel running QAM64 modulation schema (remember&nbsp;this is half duplex!). I&rsquo;ve opted for link resilience over ultimate speed. The unit runs two MIMO (multiple&nbsp;in - multiple out) &nbsp;&ldquo;chains&rdquo; one data stream is horizontally polarised and one vertically polarised. I'm monitoring link performance for a few weeks via my Syslog server instance.</p>
