Next-generation iPhones likely to focus on internal improvements.
WiFi Performance to Improve As FCC Opens Unlicensed Frequencies
On Monday, the FCC announced that it was freeing up more airwaves for Wi-Fi usage in the U.S. The WiFiForward group wrote in response to the ruling:
Today, the FCC voted unanimously to unleash more unlicensed spectrum will support all the things we already use and further drive investment and experimentation—a 50% increase in spectrum available for Wi-Fi, to be exact. Consumer devices are already equipped to operate in the band, so they can easily be adapted to quickly take advantage of new 5 GHz channels. And a new Wi-Fi standard, 802.11ac, has just been approved for the 5 GHz band. 802.11ac’s wide channels will allow for a better consumer experience.The group indicates that consumer devices will be "easily" adapted to take advantage of the new 5GHz channels, and that 802.11ac will be able to take advantage of the new bandwidth.
802.11ac or "Gigabit" Wi-Fi offers speeds up to three times as fast as existing 802.11n wireless networks. 802.11ac has been introduced into Apple's Mac line starting in 2013, and is expected to be included in the iPhone 6 later this year.
