iPhone 4S Dual-Antenna Could Drastically Improve Call Quality

The dual-antenna featured in the recently released iPhone 4S will put to rest any worries about a recurrence of the 'Antennagate' problem that plagued its predecessor.

The dual-antenna allows the phone to intelligently switch between GSM and CDMA networks, minimising the risk of dropped calls and enhancing the phone's ability to transmit and receive data.

"Frankly, I think Antennagate is dead" predicts Spencer Webb, analyst (opens in new tab)at AntennaSys. At the release of iPhone 4 critics complained about the reception; the problem was related to a certain hand grip on the phone (a.k.a. the "death grip") which attenuated the antenna's performance. Apple responded by providing users with a free "bumper" or case to get rid of the problems.

The fact that wireless signals bounce off surfaces such as walls, the ground, biuldings, etc. can cause interference that may even lead to a dropped call in poor signal areas.

Now iPhone 4S is most likely to address the issue, with its two antennas situated on the top and the bottom of the phone it means that one can receive data should the other be obstructed. Verizon already requires all its smartphones to have a second antenna placed in an offset position to provide "spatial diversity".

The downside is that now we won't be able to blame the connection if we want to end a conversation promptly!
