Electronics outfit Nokia Siemens Networks revealed Tuesday that the company had conducted tests confirming that the iOS 4.2 update for iPhone supports its Network Controlled Fast Dormancy technology, which minimizes network congestion and improves battery life.
Network Controlled Fast Dormancy (NCFD), which was developed by Nokia Siemens Networks, reduces network congestion by keeping smartphones in an “intermediate state” instead of alternating between idle and always active on the network.
From this intermediate state, smartphones can “wake up” more quickly while conserving battery life when not in use. NCFD also reduces the number of signals needed to start a data connection between a smartphone and a network.
The post did not explain what kinds of tests Nokia Siemens Networks ran to confirm the iPhone’s support of the technology, but did state that the iPhone will take advantage of NCFD on networks that support it. Nokia implemented NCFD into its own smartphones earlier this year, the post noted.
Per an unnamed Middle Eastern operator, smartphones on a Nokia Siemens Networks network had 11 hours of battery life compared to 6 hours on a competing network. Testing in North America found that Nokia Siemens Networks’ “smart networks” generate “up to 50% less smartphone signaling.”
It is unclear to what extent NCFD has been implemented on the AT&T network, but the new technology could serve to lighten the load for the sole carrier of the iPhone in the U.S., which has been criticized for poor coverage in major cities such as New York and San Francisco.
If any of you have seen improvements on this end with your iPhone since the iOS 4.2.1 update last week, please let us know.
