Live 2.5km from the phone exchange, 2.8km from the Three cell.
ADSL manages a 1750 IP profile.
Three 3G averages between 2 and 3Mbps with the dongle indoors near a window. Local cell only 3.6Mbps, but due for upgrade to 7.2Mbps in 2011.
Speeds quite consistent, abandoned landline 2+ years ago in favour of 3G and haven't looked back - it can't match it.
No image compression, no apparent throttling of any particular protocols, YouTube and iPlayer stream find at standard definitions.
You need to change your port for SMTP to work (587 I think) but MS Exchange works as is.
One 2 day outage due to major issue with cell, took 48 hours to resolve. All other outages for upgrades informed in advance via control panel.
Latency averages 90ms so not good for gaming, but in every other way walks all over ADSL on a circa 3km long line.
A real alternative to ADSL with the proviso that we're in a rural area, and so I could possibly be one of only a handful of people using it.
