Yes, channel filters will do you proud, as long as they don't provide too much loss, or too much ripple (likely more of a concern for OFDM). > Conjested mesh networks are going to need to look into this especially > with gateway nodes that operate on different frequencies (to segment an > over crowded network coverage area) yet all use omni-directional > antennas.
