That's weird. If my eyes do not deceive me I see the "B1" here use the Ubicom IP7150 https://gullfoss2.fcc.gov/prod/oet/forms/blobs/retrieve.cgi?attachment_id=1165943&native_or_pdf=pdf and not the Ubicom IP5160U according to http://www.smallnetbuilder.com/index.php?option=com_content&task=view&id=30726&Itemid=96 . Anyway who knows, no one has seen a B1 in store yet, right?
