DESCRIPTION:Abstract\n\nIn 2022 Apple announced a breakthrough. For the fir
 st time a cellphone\, without external antenna\, would be able to communic
 ate directly with a satellite. Its capabilities were very limited but life
 saving in numerous circumstances. Since then\, others have developed “di
 rect to device” (D2D) services including Starlink\, Amazon LEO and AST S
 paceMobile. Some promise cellular levels of connectivity even including vi
 deo calls in future releases.\n\nThere is now much debate as to where this
  will lead. Will the service remain a low-bandwidth fallback in areas wher
 e there is no cellular connectivity or might it grow to a solution that su
 pplants cellular\, at least outdoors? Will users access the satellite serv
 ice through their cellular subscription\, or the cellular service through 
 their satellite subscription? Might Starlink bundle fixed and mobile satel
 lite into a complete package?\n\nUnderlying these questions are more funda
 mental uncertainties such as the ultimate capacity of D2D networks and whe
 ther the business case can work for multiple operators. Geopolitics\, long
  standing regulatory issues\, and the desire for national sovereignty also
  confuse the picture.\n\nThis presentation will explore these questions. I
 t will set out the issues that determine capacity\, coverage and the busin
 ess case and develop initial predictions and estimates. It will address ge
 opolitics\, spectrum\, current positioning and build a range of scenarios.
  It will set out what can currently be determined and where there remain g
 enuine uncertainties.\n\nSatellite D2D offers much – a path to ubiquitou
 s connectivity in short timescales. But the history of large-constellation
  satellite networks is littered with business failures. This presentation 
 ultimately asks whether this time things will be different.\n\nSpeaker(s):

 There is now much debate as to where this will lead. Will the service rema
 in a low-bandwidth fallback in areas where there is no cellular connectivi
 ty or might it grow to a solution that supplants cellular\, at least outdo
 ors? Will users access the satellite service through their cellular subscr
 iption\, or the cellular service through their satellite subscription? Mig
 ht Starlink bundle fixed and mobile satellite into a complete package?</p>
 \n<p>Underlying these questions are more fundamental uncertainties such as
  the ultimate capacity of D2D networks and whether the business case can w
 ork for multiple operators. Geopolitics\, long standing regulatory issues\
 , and the desire for national sovereignty also confuse the picture.</p>\n<

 es that determine capacity\, coverage and the business case and develop in
 itial predictions and estimates. It will address geopolitics\, spectrum\, 
 current positioning and build a range of scenarios. It will set out what c
