Just when everyone thought that the signal problem would no longer be a constraint on Apple’s products, Apple’s mobile phone was on the hot search again because of the signal problem. At this time, the signal problem has nothing to do with Intel.
Of course, this is not the first time Apple has fallen into the “signal gate”. The poor signal of the mobile phone is more likely related to the antenna design of the mobile phone.
In June 2010, when the iPhone 4 went on sale around the world, apple called the thinnest smartphone of all time, but a series of strange things happened. Users quickly find that when they hold the phone in their hands, the phone network signal disappears, and sometimes the call is completely interrupted.

Another week later, media led by consumer guide advised users to avoid buying the iPhone 4. Under the attack, apple chose to compromise. At the emergency briefing, jobs acknowledged Apple’s imperfections. The iPhone 4 is not a software problem, but a hardware problem. Apple will provide users with free mobile phone protection shell to avoid “death grip.”.
The baseband chip of the mobile phone is responsible for information processing. The processed information is sent to the base station through the radio frequency chip, and the base station feeds back the signal to the radio frequency chip, and finally completes the mobile communication.
The bad signal of Apple mobile phone is not only the problem of baseband performance. “Baseband is like human brain, radio frequency and antenna are like mouth and ear. If one can’t understand what you say, it doesn’t mean that the brain is bad
