This is typically LTE transmitters etc.&nbsp;</p> <p>To be able to attenuate signals from the transmitter at the band edge, just 1 or 2 MHz away, you&#39;d need an incredible sharp filter. Unfortunately, this doesn&#39;t exist.</p> <p>The only remedy for using channels near the band edge is to lower the output power until you pass, use channels further from the band edge or lower the bandwidth (data rate).</p><div style="clear:both;"></div>
