iPhone 4 Wi-Fi Repair
Wi-Fi is the name of a popular wireless networking technology that uses radio waves to provide wireless high-speed Internet and network connections. Wi-Fi works with no physical wired connection between sender and receiver by using radio frequency (RF) technology, a frequency within the electromagnetic spectrum associated with radio wave propagation. When an RF current is supplied to an antenna, an electromagnetic field is created that then is able to propagate through space.
iPhone 4 is equipped with 802.11 b/g/n Wi-Fi which is quiet faster than its predecessors. Because is the most widely available of the standards and is backward compatible with a, b and g. It significantly improved speed and range over its predecessors. For instance, although 802.11g theoretically moves 54 megabits of data per second, it only achieves real-world speeds of about 24 megabits of data per second because of network congestion. 802.11n, however, reportedly can achieve speeds as high as 140 megabits per second. 802.11n can transmit up to four streams of data, each at a maximum of 150 megabits per second, but most routers only allow for two or three streams.
iPhone 4 Wi-Fi is manufactured along with Bluetooth as one component, hence the whole wi-fi module will have to be replaced if either is faulty. Wi-fi module is located on the internal motherboard assembly. If you have any problem using your iPhone 4 Wi-Fi or if you are not able to connect to any wireless networks then it is time to get your iPhone 4 Wi-Fi repaired by a professional.
