I take it that you haven't read the recommendations in the Oireachtas Committee's report about public ownership or the submission by the UL experts in public-private partnerships. If you search for Oireachtas Committee on Communications you'll find the report and you can scroll to the opening statements to find the UL one. (Sorry, I cant post a link).

The chances of ending up at the same place after a new tender seem high to me as the same questions and analysis will take place. Could it be that you don't see the value in achieving what the nbp is trying to do?
Messer1 wrote: » On the contrary, I made a detailed submission to the Oireachtas Committee proposing an approach to the NBP based on combining fibre, LoE sat, VHTS, 5G and next gen FWA and argued that this would bring high-speed BB more quickly and at lower cost than the NBP's all-fibre soln. Ignored!

Messer1 wrote: » SpaceX plans to launch up to 60*4 LEO sats before end this year and up to 60*24 next year. Starlink needs about 6 launches for 'minor coverage' and an additional 12 for 'moderate coverage'. About 24 launches will initiate worldwide coverage. Additionally, it has sought FCC approval to increase the number of orbital planes from 24 to 72 to broaden coverage so as to include southern US states ahead of next year's hurricane season.

Messer1 wrote: » All going well, initial service for Ireland should start in 2022. The FCC license requires SpaceX to have 5,900 sats in orbit by end 2024. By that time, about 20 sats could be servicing Ireland at any one time.

With fibre, when you run out of capacity in one cable, you can just run another one alongside it. You can't do that with anything radio based.
Messer1 wrote: » You add more satellites to the constellation. This is what all the LEO sat operators plan to do.
plodder wrote: » Sooner or later you must run into an upper limit of bandwidth that the air can carry though. The satellites are >340km up. It's not like terrestrial networks where you can compensate to some extent with smaller cells. They are all competing to some extent for the same bandwidth, I assume. I don't believe you can keep adding satellites ad-infinitum, in the same way that you effectively can with fibre cables on the ground.

Those low earth orbit satellites will lose orbit and eventually crash and burn up in the atmosphere. They are governed by the laws of physics and cannot provide the necessary bandwidth required for remote dwellers here or elsewhere. Whoever would suggest Satellite as an option is quite simply raving and talking out their arsehole.
Messer1 wrote: » You use "spot beams" to aim signals at specific areas. This enables frequencies to be used multiple times. The next gen VHTS currently being built will have massive bandwidth eg up to 1 Tbps. I assume they will have spot beaming capabilities.
plodder wrote: » I read somewhere, and I don't know how accurate it was, but it sounds reasonable, that the capacity of each satellite is around 20Gbit/s which is only a couple of strands of fibre. While I think these will be a big improvement on the previous geo-stationary generations with regard to latency, I just don't see them playing a significant role in broadband for this country. The Australian outback maybe or remote rural areas of the US or developing world perhaps.
Messer1 wrote: » I concur on the 20 Gbps. You have to multiply that by the number of sats in line-of-sight over Ireland at any moment - about 20 in 2024 and 40 in 2027 for Starlink alone. So up to 800 Gbps. Add Amazon etc to that.
theguzman wrote: » 800Gbps will be enough for 800 homes in 2027, it is a solution for extremely remote locations who deserve good bandwidth, using it in Ireland would be a waste of the technology and by 2027 the NBP will be built and everyone will be on fibre.
