Xbee radio recommendation for Navio 2

Thank you for your reply.

In the end I have decided to use Orange RX/TX: http://www.itluxembourg.lu/site/
see this post: Rx and Mavlink Telemetry in one?

I have also read somewhere abou Xbee not being well suited to this application. From what I remember the cited reason is Xbee latency.
