Ahem as has been mentioned if you have a KA-Sat based service low latency is not an issue the refractive index of microwave transmission is lower than fibre optics and thus the latency is lower.

If the engineers applied themselves they could cook an egg on your head

I understand your logic but you are forgetting about the distances involved when sending data via satellite. Latency is measured over the round trip (what we called ACK/NAK when I was in comms):-

House -> Satellite
Satellite -> ISP
ISP -> Satellite
Satellite -> House

Here is some simple maths. The satellite will be at around 36,000km. Multiply it by 4 for a full round trip and you get 144,000km. Now divide this by the speed of light and you get 480ms. This is pure travelling time, then you need to add hardware latency and the latency between the ISP and whichever server you're trying to reach. In other words you'll be in the low 500's at best.

Unfortunately 500ms is way too slow for online gaming.

Whatever....

Blimey this thead is getting à bit too technical événements for the liés offre me....
But thanks for all help given concerning my particular case

Maybe a silly question, but is there any possibility in using a "clé 4G" for the home and therefore bypassing any need for ADSL?

I have always found that if you get the angle of the dangle wrong then you are banjaxed!

Yes definitely. In theory both the speed (up to 100mbit/s) AND the latency (less than 20ms) should be better than ADSL so gaming over 4G ought to be fine. It remains to be seen what the networks deliver though!

Not an issue but it again will be a location location location for speed, We have a mast close to us which is also near a school and at peak hours they throttle it down to edge "GSM Slow" connections for lower tariff customers, it's common practice

Ok, So if I get this I can, in theory get 4G on all appliances in the home?

The product looks great and yes of course it will do exactly what you suggest. It's the equivalent of a personal hotspot on your mobile phone. Not sure what forfait you need to get with it - cost per month, Gb per month etc. You also need to know what coverage you will get in your area. But very interesting and if you get one do tell us all how it works out.

Yes you can the main downside is the price you pay for bandwidth. But looking at the coverage map your commune has not got 4g but upgrading the mast's does not happen over night and the transition from GSM to 3G was not the fastest when I purchased my iPad 1st gen our town still didn't have 3G

OK thanks for that - We may not have 4G for the time being where we are, but I'm supposing that we'll have 4G before we have a better ADSL line. We do however have 3G so I'm presuming it should work with at least that. Would 3G be a better option that my actual ADSL internet connection??

Difficult to say but you can check it out quite easily by going to the speedtest.net website on your PC to check your ADSL's download and upload speed and the latency. Then do the same on a smartphone after downloading the speedtest app. If you don't have a smartphone then you'll need a friend who does have one to help you out here but just make sure their phone is on the 3G network that you plan to use. It's completely free to do.
This test is not definitive because many 3G networks throttle back your speed if they detect you are doing a big download such as a torrent or a youtube file or if you start up a software update. This phenomenon can also occur if the network is overloaded or you have gone past a certain quota within a certain timeframe. 4G is likely to be much improved in this respect. Good luck!

Are there any close proximity neighbours that have Adsl that can be asked what their connection is like?

Yes, my neighbour has Orange and it isn't much better than mine but he does get the TV via his satellite. FREE doesn't offer this service so I'm screwed as they were the only ones offering me an ADSL line.
He, my neighbour that is, had real trouble getting orange to open up a line and he played hell, as being self employed he was, like me, in dire need of an internet line but Orange refused as apparently his address didn't exist . In the end somebody's arse was kicked and he was given an ADSL line but not after waiting over 4 months.
It really is an appalling service especially in todays world. Our kids are told to go onto the internet to do their homework - if we didn't have it I have no idea how we'd go on.

I did a test earlier on :

ping 63ms
download 1.35mbps
upload 0,41 mbps

leaves a lot to be desired.....
