E mail from BeepTool, page-494

Only a thought, but Beep Tool use the words Beep Tool Satellite Smart Phone.

It seems that at in the case of the three Diamonds that Beep Tool is acting as a suedo telco. Hence why they are the ones selling the modems and the phones!!

SAS is being paid for the use of bandwidth.. This is well understood.

I did a dumb bum search like, how do satellite phones work... Doh

A sat phone, as you may gather from the name, routes calls via satellites instead of land-based cell towers. There are a number of satellite networks that are used to make calls, but they generally fall into two camps: geosynchronous and low-Earth orbit.

Low-Earth orbit satellites are not geosynchronous — their orbit takes them over different parts of the Earth — and they fly lower, usually between 400 and 700 miles from the ground. They orbit quickly, taking between 1 and 1.5 hours to circle the globe.

Because low-Earth orbit networks require less power to access, satellite phones that connect to these networks are smaller — generally only slightly larger than a standard cell phone.

Cheers.
