In lack of a tech group in the forum I take this to the lounge.

Does anyone have experience with the new Claro 4G Internet?
How does it perform and what are experiences.

As I have seen 4G tech implemented it has performed like 100 Megas, and up to 1000 Megas (1 TBPS).
Pretty impressive velocities for wireless.
Here is info on Wikipedia about the technology: 4G - Wikipedia, the free encyclopedia

I have set up the Claro 3G connection for some people I know and I have experienced it to work pretty fine in some cases. I have measures up to 1,6 MBPS download speed.
The downside has been poor coverage and very weak signal during rain.
