In the 5 GHz range, I have a much better field strength.
At 2.4 GHz, it has not become much better, really no change.
But is also somewhat subjective, I have no measuring equipment.
The Galaxy S2 is at 5 GHz Wi-Fi at more bars.
The Sona BD player gives me now 100% signal strength at 5 GHz.
My PCs are connected with Fritz WLAN sticks (2.4 GHz).
Da has not changed very much.
