In addition - even the purpose built VoWi-Fi handsets (Polycom, Cisco, etc.) are physically larger that iphone and much time is spent designing antenna's to improve their functionality and RX sensitivity.

This discrepancy can be as much as 3dB. If your using these devices to purely take the worst-case scenario - then good. If not - then you're not getting a clear picture of the typical user experience.
