WiFi hardware compatibility issues in iPhone 4s with iOS7 software Prepared By: Bhumika Gohel
WiFi l l l l l l Wi-Fi is the name of a popular wireless networking technology that uses radio waves to provide wireless high-speed Internet and network connections. A common misconception is that the term Wi-Fi is short for "wireless fidelity," however this is not the case. Wi-Fi is simply a trademarked term meaning IEEE 802.11x.
The iPhone 4s The iPhone 4s uses a Broadcom BCM4329 WiFi and Bluetooth controller the same chip likely used in the iPhone 4. The BCM4329 is a popular choice for mobile applications where it may be in use in hundreds of millions of popular mobile devices — processor analysis firm Chipworks estimates that the chip was found in more than 50 million devices in the fourth quarter of 2010 alone.
iOS7 iOS 7 gets a complete design overhaul and adds useful features like automatic updates to make everyday use easier. Long-overdue Control Center gives quick access to most-used features. AirDrop and iTunes Radio are excellent additions. While there are a few notable new features in iOS 7, the new interface is by far the most deeply felt and most profoundly changed of the batch. l l
Disadvantage of iOS7 Besides the massively overhauled design and Control lCenter,there are few ground-breaking new features . The flat design concept favors space over information so l l you'll generally need to do more scrolling to get the info you need. Some new features aren't available for iPhone4 and 4S users. l

solution iOS 7 needs a powerful processor—the "brains" of the device responsible for carrying out what the software commands. Apple designed the operating system for its most powerful chip to date, the 64-bit A7, which includes both a CPU and an upgraded graphic processor. The OS simply won't work on chips that predate the A4, the earlier and weaker chip powering the iPhone 4.
Cont.. It also doesn't help that the iPhones 4 and 4S—the earliest devices eligible for this software update—have half the onboard memory, or RAM, of the newest iPhones. RAM holds recent data for easy access, so the more you have, the more data you can access quickly, and the faster the experience feels. The iPhone 5S and 5C boast 1GB RAM. The 4 and 4S each have a mere 512MB.
