Recently, I’ve spent a week on vacation in Vienna, and I used a bit of that time while walking around and spending time in cafés to have a look at the performance of the LTE and 5G networks in the city. With the EU’s ‘roam like at home’ rules, I didn’t need a local SIM card for this, and as long as the backhaul between the visited network (in Austria) and the home network (in Germany) is properly dimensioned and configured. In effect, this home network detour only adds a few milliseconds of delay. And indeed, while I was in Vienna, I could easily exceed 1 Gbit/s downlink throughput. So while it is good to see that such high speeds are achievable even while roaming, it’s availability and capacity that are the main differentiators these days from my point of view.
