The iPhone 5 Should Again Deliver an Improved Antenna

The iPhone 5's slight increased in height, combined with Apple's other design changes, should improve signal reception according to Spencer Webb, antenna expert and owner of AntennaSys. Webb wrote extensively about the AntennaGate issues with the original iPhone 4.

Because the iPhone 5 is taller, Webb explained to MacRumors, it has "increased antenna spacing and thus the antenna diversity will work better." Antenna diversity allows both the upper and lower antennas to send and receive signals -- a feat that the iPhone 4S was the first to accomplish. "The probability that one of the two antennas has a better signal is higher."

Ergonomically, the taller phone means the average hand won't be able to cover both antennas. It's harder to hold "wrong". Also, since LTE operates at a lower frequency, 700 MHz, the additional separation is even more valuable.

The aluminum body of the new iPhone 5 will also help the antenna performance, and the hand sensitivity issue will be further diminished. The key word is sensitivity. In other words, changes in performance due to changes in "how you hold it" will be diminished. The antenna will see less change in the "ground mass" of the device.

Webb also noted that LTE support could actually help with network congestion in some cases. "The higher speed may have more to do with relieving network congestion than the requirements in the apps -- it gets the traffic out of the way faster."

Many tasks that are normally performed on the iPhone -- Google searches, fetching email -- will still be performed on the LTE-equipped iPhone, but won't be using the carrier signal for as long. Additionally, LTE gets data users off of the traditional cellular network, so 3G data connections and voice calls may be more reliable.

Glad to hear. It's been over two years with my iPhone 4 and it's problem prone antenna. Hello iPhone 5!

Also, It'll be nice not to have to hear people knock the iPhone for it's antenna problems. I'm glad to see Apple is starting to be an industry leader in antenna design.

Shame they can't say how much better it is since they are still selling the old phone with their inferior antennae.

I came here wondering this exact thing.

I followed the live blogs and for the iPhone & iOS6, we basically heard everything over again that Apples own intentional leaks already told us. I still want to know ...

How much ram?

Will LTE function simultaneously w/voice/data on other networks?

It's largely up to the networks and the handset makers. I believe most LTE radios are capable of it these days.

As for RAM, apple usually doesn't tell. I'm guessing 1GB, but we'll need to see teardowns or diagnostic app screencaps to be sure.

Oh their was definitely a problem and Steve lied his ass off and many believed him.
Antennagate was way over hyped. Every single phone in the world had the same issues to varying degrees. And Steve told it as it was. At least Apple tried to fix it on their new phones. The slight problem that existed.
