GoBus WiFi Performance
So on my various trips back to Ireland I started to take the non-stop airport service to Dublin Airport from GoBus! As I had my laptop with me to try out the on-board WiFi a few times now, I decided to run a Smokeping over the route, just to see the latency experienced across the journey, the script was set-up before for another project but seeing I’ve never done any network tests on 3G access until now, it would be interesting to see the results of true mobile internet was like. So using Smokeping and a laptop I went about running the test in background. As the objective was to work on the internet and monitor the latency from a few points on the internet . It would give a good feel for how the 3G-WiFi Gateway handled multiply users over a single 3G connection.
The Tests
I picked sources, Google.ie, Eircom DNS and IBB. this is an example of google.ie over 1hr I got an 1.2sec avg and up 65.33% on packet loss, this was requesting 20 pings over 300s. So quite spread out but as GoBus is a non-stop service it’s hard to say if it improves when the 3G uplink stops roaming across the mobile cell sites. Below is an example of the ping over 1hr, If I had a bluetooth GPS one could log the position information and match that along the route as some locations long the journey you would lose the connection for almost 4sec’s. for IM and broweing thats fine, and I think i was the only passanger online so with a few people online service won’t be the best.

Hardware
to make this possible tehy use a 3G Gateway for WiFi Backhaul, it’s got all the advance features of any enterpirze access point, (WPA2 Enterprise & 802.1x) but with the added benifit it can provide up to two possible WAN links for seamless connectiviy. However it wasn’t what we expearenced onboard GoBus. but the H/W isn’t to blame as
