DB seem to be using the wimax setup which requires a box every 2-4km along the line, wimax might do 75km but when mobile it can't. The 3G/satellite arrangement avoids the need to fit boxes everywhere, that said you can have 3G/wimax/satellite onboard if you wish, handy for tunnels |

In simple terms its the more expensive way to do it and is geographically restricted
In the UK if you took one of the GNER trains with Wifi it would work just about anywhere in the UK, such flexibility is good The free proposal for Ireland was based on the wimax option though the practicalities of it and the use of IE's dark fiber optic network didn't seem to be worked out |

PS Does the Port Tunnel not count? :D |
First class and standard are different coaches. The kit has to be certified to rail safety standards so a cheap router off ebay won't work. The laws of physics are a problem, faster you go the more difficult the connection is, 90kph vs 165kph. Railways are full of deep cuttings and isolated countryside
Principle concern is slicing a hole in the roof for the satellite receiver |
can we just keep this simple? otherwise you all know where this is going.
mkkkkkaaaaayyyy? |

I noticed on the 4pm Dublin-Cork train last Thursday that there was a wireless network showing up as "Free Public Wifi" or something similar. Is there some sort of roll-out planned?
At the moment, there doesn't seem to be a DHCP server, so it's useless. |

I can report that Irish Rail are conducting trials of Wifi on the Dublin Cork route using 3G only. Borrow a computer science student, get a modem from the 4 networks and its easy enough hack something up. Though IE really need to be looking at something like this http://www.icomera.com/m400_overview.php?id=1&p=1
It works but there are 3 major blackspots en route. 3G coverage is rubbish outside populated areas. Other routes ruled out due lack of coverage Talk of filtering as well to block youtube, to avoid the connection being saturated with unproductive traffic |
Satellite download might be ideal for cuttings and remote areas.
|
something like this (scroll to near the bottom) - would be a start
|
The best solution is one unit per train as each 3G modem is competing for the same bandwidth
Remember the business case is based in access to the trains computer for operational reasons not kids on youtube |

Blame 02 for the bad connection
It looks to be targeted at business given its Cork only, given the constraints on the link blocking youtube and then other less how shall we say graphic sites is not unreasonable What was GNER in the UK are looking to clamp down on high bandwidth users |
