MacRumors is reporting that the iPhone 4S has a significant upgrade to the antenna. The new system will be able to dynamically switch between antennas to resolve signal issues.Apple has come a long way since the AntennaGate fiasco that surrounded the original iPhone 4, and Spencer Webb of AntennaSys says the new design may have huge implications for the industry.The iPhone 4's design was based around having the various antennas located around the steel band that surround's the device's sides. The top part housed the Wi-Fi and GPS antennas and the bottom was home to the cellular antenna. Many users reported signal issues with the design, something that may or may not have been mitigated in the CDMA version of the device.
Webb theorized that the CDMA version changed the design. The Wi-Fi and GPS antenna were moved to the back of the phone's body and a second cellular antenna was added to the top of the steel band. This "spatial diversity" helped improve signal issues, but was limited in the way it sent and received data. Namely, it's believed that only the bottom antenna could transmit data.The iPhone 4S's design is similar, but Apple says that it will have "send and receive diversity" for both CDMA and GSM. This means that the phone will be able to dynamically change which antenna is transmitting or receiving data, something that can provide a huge improvement in cellular performance.Webb also stated:The iPhone 4S may indeed be the first phone to have diversity on both the send and receive sides, and that is a decently big deal. They still have the antenna around the rim, though, so it's evolutionary, not revolutionary.As we noted in our Live Coverage, the new iPhone 4S will have support for 14.4 Mbps HSPA. How much of a difference do you think this improved antenna system will make? Will it set a new bar for the industry?[via MacRumors]TweetRelated PostsApple Patents New Antenna Design; Plans To Hide Antenna Behind Apple LogoApple Explains Smartphone Antenna Performance And Their Weak SpotsiPhone 4 Reception Issues – Competitors Take A Jab While Apple Scouts For Antenna EngineersiPhone 4 Owners Reporting Reception Issues When They Hold Antenna Band?
