I've been a digital nomad for almost a year now. If I can get 5 Mbps down/up, I can do my work without interruption. In a couple places where I could only get 1 Mbps down/up, I could still do my work w/ a bit of patience on transfer speeds & good enough audio, as long as I didn't need to do much screen sharing & video uploading, and I could usually compensate when I really had to by tethering/hotpotting to my mobile phone. !0 Mbps would be fine for one person for most things. Might feel slow for a family during peak times.
