According to information on the official O2 website browsing is not recommended where I live both inside and outside of buildings, as maximum EDGE is applied with an average of 110 kbit / s. Right. But what can you do?
Clear answer: This antenna BUY!
I received the antenna about 30 minutes before, had infected them and without specific orientation on windows placed (cable is plentiful).
And now?
I'm sitting in my house, outside it pours with rain and I'm surfing with HSDPA and an average of 1.5 Mbit / s !!
My O2 dealer is fully finished, as the next HSDPA capable mast in a mountainous area is about 12 km away, and then even in completely the opposite direction to my antenna.
I will then times change rooms, perhaps I'm still at 7.2 Mbit. Madness!
