The problem with normal internet is that it is an instantaneous system where the data is downloaded as per the user requirement and different users have different data to be simultaneously downloaded, thereby reducing bandwidth per user. Suppose instead of this we have a system where the data is not downloaded on demand but is serially transmitted at a high speed like 1 Gbytes per second. This means that in 24 hours, a channel of 1 Gbytes/sec
So whose data takes priority? Remember that some of us really really don't care about downloading gigabytes of data, but we want low latency interactive sessions. Half an hours waiting? We start screaming with more than 1 sec of response time in the round trip.
can transmitt 24 x 3600 Gbytes of data. This corresponds to 86400 Gbytes or 86.4 terabytes of data in 24 Hours. The user has no choice but to wait for 24 hours for the next broadcast in case he/she has just missed it. If the satellite has 24 transponders then this data is split into 24 slots of one hour each. So now the waiting peroid for the next download is only one hour. If the transponders are 48 then this further reduces repeat download time to half an hour only.
The final result is that the downloadable files are available to *everyone* within the satellite footprint at a speed of 1 GBytes/second subject to a
This sounds so much like TV, rather than Internet. News flash: The Internet is not television.
maximum waiting period of 1 hour or 30 minutes. So everyone benefits equally and parallely. This will bnefit remote schools, villages and anyone in any remote part of the country.
What happens if none of the content being broadcast is what I want?
All data will be linked to an index file that will be transmitted as a pilot file. This file will be a mini website cum search engine classified into topics and subtopics. These will link to the actual file and its corresponding transponder and its broadcast time. A timer in the receiver will mark this file and download it at its arrival time into a buffer harddisk or directly into the computer depending on the hardware design. This will be very usefull for downloading large files, cds, dvds and other bulky data. Entire newspaper websites can be downloaded for liesure reading. Imagine downloading 4 CDs of Linux within 3 seconds flat.
I can. I still prefer fibre to the house.

Please send your suggestions and criticisms and if you like the idea, you can very well use it and help to provide a real high speed net for everyone. Many of you guys are in high positions in big organisations and you can set the ball rolling.
Unhappily, its actually cheaper to roll out fibre and recover your costs over a slightly longer period of time. Plus, what happens to different protocols like the peer to peer applications?
