Satellite internet

And can somebody tell me, they say you are not suppose to use P2P on the cheap packages, but it is ok (I assume) to max out the connection downloading from HTTP ... so how does it make difference for them if I will be using HTTP or P2P? The traffic cost the same at the end of the day.

cause http is client/server , u download a 10mb file, you use up 10mb bandwidth
P2P is peer well.. to peer.... u download a 10mb file, but also normaly up as much, so thats 10mb bandwidth.

And torrents are like worst ones, cause theyre like p2p2p2p2p2p2p2p2p2p2p2p2p2p which makes them cool :)

but dont radio waves travel at the speed of light? just curious.
i know it took like 6 minutes for communications to reach mars probes when sent from earth. sounds like speed of light.

6 minutes? Hmmmm, heard more like 26 minutes. Anyway, if they used radio technology for comms, it would probably be a bit on the daft side (but with americans you will never know)

As far as I am aware they used laser technology.

Radio waves do NOT travel with the speed of light, if it did, we wouldn't have lag like we do with satelites. Also, if you've ever called into a radio station and heard an "echo" is because there is quite a delay between you speaking and them broadcasting the spoken word back to your radio.

If it worked with the speed of light, WBS would suck less....

Microwaves travel at the speed of light.

Of course they do, the delay on the radio station is the propagation delay through the electronic transmission network and delays caused by the CODECS on either side. All radio stations in SA use TELKOM's transmission network. 5FM is connected via FPMX into a 2Mbit link, So is 94.7 and Jacaranda and Radio 2000

Sattelite lag is due to the fact that the processing electronics needs to process the signal for retransmission on the outgoing end. Don't forget that there is also multiplexing (FDM/TDMA involved) which induces even more delay

Electromagnetic energy travels at 3x10e8 m/s

ll electromagnetic radiation -- from radio waves to x-rays -- travel at the speed of light.

just googled it... so guess that answers that.

i think satelite slows things down becasue the signal gets bounce around alot and then bounced back which ends causes the lag.
 
Sat does travel at the speed of light, its even been calculated on this forum before (just cant remember where, it was back in 2003), even at the speed of light, it takes a long (+600ms) time for a round trip, if you think about it, thats not long at all, with fibre, the data must go from you directly to international server, then back for round trip, with SAT, its a whole lot more, data leaves your PC, gets sent to the edge of the earths atmosphere to a GeoStationary satellite, back down to earth halfway across, then does the atmosphere loop again.

the optimal solution for us in ZA, would be to use a DSL for uplink, and uncapped SAT for downstream, then the lag is only 300ms + (dsl transmit latency +/- 120ms)=420ms in optimal conditions, we would then get semidecent latency, and great data throughput.
This is still a nice dream, as the only people allowed to route traffic in and out of ZA are TelKum and Sentech.
 
The problem is if you think sattelite internet is better than this, youll be in for quite a shock, the latency is far worse. Unfortunetaly we are stuck with this. Hope WBS do eventually sort it out, ill give them until Telkom make a product as cheap (so i guess ill be stuck with them forever :D)
 
Satellite Internet at affordable subscription

:) For all persons out there fedup with Hellkom pricing and sub standard service, there is an affordable option on its way to SA for satellite based internet.

At the moment it would consist of simplex services with unlimited downloads.
32\128 R300

Two way satellite internet to follow soon.

hmmm, OK maybe its just me but I see one way sattelite connections as a step backwards especially 128kbit, of course it isn't capped, its 128k, ISDN isn't capped either (and you only get satelite for download but have to maintain another connection to upload at the same time) and you get bad pings (way worse than dial up), so really you would be better off with ISDN or dial up, or am I wrong?
 
In the UK I almost got EuroSAT, but then they told me I still need a dial-up modem + phone line to logon to their network, before you can surf. Needless to say, I opted for BT ADSL instead....

Imagine having to phone a European number every time you want to surf.
 
exactly, a 2 way sattelite internet package is a different monkey all together, but I don't think those are ideal for users unless you live so far away from civilisation that it's your only option. I think if someone could make a large internet gateway with a 2 way satelite connection and offer access to that gateway over wifi that could be cool, probably very illegal, but cool
 
yes indeed, and it is being research as far as I know, both here and worldwide but right now it isn't an option
 
the idea of leapfrogging over and bypassing local Net and restrictions, is still a great idea - can the tech/sat geeks keep forum advised if there're any solid tangible routes which open up in this regard.
I think there might be legislation re 'intercepting external/international sat signals' - but again, the powers that be have to actually FIND you before they can do anything..
