Check out LTE 4G datalink device for Bebop2 and Bebop2Power. Useful when flying in high wifi interference areas or doing non line of sight flights.
I'm also impressed if they really have a real client for reference... with that price...eemmm..
Several months ago I read was USD$7XX without covering Disco itself. If I am not recalling it incorrectly. Recently, they've removed the price on the site.
