We are preparing to deploy our first B41 system. The channel bandwidths are limited to 10 or 20MHz. The way the FCC allocated EBS in the US does not align well within these limits. It would be more efficient if there was an option for 15Mhz (technically 16.5Mhz) so that a deployment could use the contagious EBS blocks 1-3.
That would make for a more efficient use of the available spectrum.
