AT&T Had Apple Tweak iPhone to Reduce Network Strain
Mar 31, 2010, 7:50 AM by Eric M. Zeman
The Wall Street Journal reports that AT&T sent two of its wireless networking experts to Apple during 2009 to find a way to reduce the iPhone's strain on AT&T's network. The two companies worked together and Apple invented new technologies that changed the way the iPhone connects with AT&T's cell towers. Based on continued meetings between the two companies, the iPhone now puts less stress on the network when seeking cell towers and checking for text messages. In addition to these changes within the iPhone itself, AT&T has taken measures to improve the network itself. It is still tweaking cell tower configurations, adding cell tower backhaul capacity, and adding cell sites as part of a 100-day improvement plan.
