IO540: Do you use a 3G dongle/mobile phone or do you get info from the internet at home and then use flight planning software on your laptop?
All of the above.
Well, actually I don't currently use any USB dongles; I use a mixture of
- a bluetooth connection phone-laptop (the simplest, usually)
- a laptop with a built-in GPRS/3G radio (they are not common)
- a
Huawei E585 GPRS/3G to WIFI radio
There are various ways to get mobile internet access
e.g.
If you can't get GPRS/3G then you are a bit stuffed... but the "dongle" products tend to not have the best reception anyway. Using a phone is thus better because you can position it somewhere higher up.
