Will the iPhone 4S dual antenna design improve your call experience?

One of the big talking points after the release of the iPhone 4 was the so called antennagate problems. You must remember that; Apple introduced its free bumper program to quell the discontent. Apple claims to have improved the antenna on the iPhone 4S but what have they done and how does it work?

Improving on the innovative stainless steel external, dual-antenna design of iPhone 4, iPhone 4S is the first phone to intelligently switch between two antennas to send and receive. iPhone 4S now supports twice the download speed with HSDPA of up to 14.4 Mbps and iPhone 4S is a world phone, so both CDMA and GSM customers can now roam internationally on GSM networks.

MacRumors spoke to Spencer Webb, owner of AntennaSys who had already written extensively about the original iPhone 4 antenna problems. He claims that Apple moved the GPS and Wi-Fi antennas in the Verizon CDMA iPhone and turned the top antenna into a second separate antenna. This gave it spatial diversity which in simple terms gives it the ability to switch antennas if one has a poor signal.

The Verizon iPhone 4 only had “receive diversity” or switching between antennas on the receiving data. The iPhone 4S on the other hand has both “send and receive diversity”; which should lead to a much improved call experience. Let’s hope so as the iPhone gets a lot of criticism for its poor call quality and stability.

I for one have never had any issues with my 4 on Verizon - call quality has always been outstanding, but I'm sure your area has something to do with it. There must have been something to "Antenagate" or it wouldn't have been started in the first place - but I believe it was blown up bigger than it actually ever was.
This looks like a good upgrade...

lazerbyte says:

I am hoping that it will as at my condo there is a DEAD spot that I keep getting disconnected on! Here is also hoping AT&T improves their network!

Carlos Lopez says:

I sure hope so. Anything to make up for AT&T's crap network. Sorry, still in contract, can't switch.

Doubting Thomas. says:

Confused. How can an arial on a phone I don't own, improve the reception on mine? Wouldn't happen with Android.

Nor says:

I see. The Android operating system has a good antenna? Learn something new every day.

Colleen Rawlings says:

That is why your phone is fugly :P

You says:

I know. That is why I envy your beautiful brick.

I've been an att user since the first iPhone and I've never had a problem with my iPhone call quality my iPhone 4 has been the best by far and I'm left handed so antenna gate should theoretically been a problem for me

MuthaFU says:

You dummys iit's the phone not the service. They settled this a while ago.

Tyson Trogdon says:

I've never had signal issues with my AT&T iPhone 4, even when I deliberately used it without a case and tried the "death grip" thing.

EagleyeSmith says:

I hate cases. I kept my bumper on for about a few months w/an InvisibleShield. Then one day woke up and said, "It's time ... It's time to be NAKED!" Haha. Been rocking the nude ever since.

S Huckaba says:

Looks like the more we learn about 4s it is a big improvement afterall. Still going wait till next one. Need to go back to keeping phone 2 years.

EagleyeSmith says:

Never had the antenna problem w/my iPhone 4 (not saying some people didn't, just my personal experience) But my home buttom, hey now, I had to get my iP4 replaced because of that little thing.

Pedrocas says:

I have poor to no reception at work. Do you think the dual antennae will alleviate this problem. Outside of my work walls, the reception is better. I have been reporting this issue via AT&T's Mark the Spot App.

"You dummies it's the phone not the service"
Agree.
