There's an A5? I on saw an B1 posted recently. And yes this one has better processor more RAM and better range overall around 6dBm higher radio power. IOW from cisco rule of thumb it would have twice the range of the A4 https://gullfoss2.fcc.gov/prod/oet/forms/blobs/retrieve.cgi?attachment_id=1165949&native_or_pdf=pdf
