Bob Mansfield reduced role to focus on chips, senior execs given new responsibilities

Executives

Apple executive Bob Mansfield’s unexplained departure from Apple’s leadership team is due to the long-time engineer’s desire to focus on chipset design plus future products and less on executive duties, according to sources with knowledge of the change.

As part of Mansfield’s leave from the executive team and role change to “special projects” under Apple CEO Tim Cook, Mansfield’s former duties as Senior Vice President of Technologies have been split between two Senior VPs: Hardware chief Dan Riccio and Operations head Jeff Williams, according to these sources.

Inside AT&T’s 83GB/hour mobile cell tower …or why your iPhone no longer drops out at huge events

LA_Music_Festival_Photo_with_Captions (1).

AT&T shared a little bit of what goes into a portable network cells they put up at special events where bandwidth needs will be extraordinary. Remember, AT&T’s network is about 80% iPhones so this is important stuff. The setup above was what they used to cover a recent Los Angeles festival (read: Coachella).

This isn’t a test network; AT&T’s been honing their skills since they got caught with their pants down at SXSW in 2010 (back when AT&T was the only US iPhone carrier). Since then, with their mobile response team, they’ve been able to keep their network up and running at huge events with the addition of these ‘kits’ above.

The  network performance stats for this setup – some of which are staggering:

  • Carried approximately 83 GB of data traffic during the peak hour on our in-event network
  • Carried a combined 6,054 GB (or more than 6 terabytes) of data on our in-event network during the two weekends of the music festival (24-hour traffic totals, Friday-Sunday for two weekends).
  • About 50 engineers were involved in planning, construction or onsite 24/7 monitoring.

Both the super multi-beam antenna and five-beam antenna are AT&T innovations that were conceptualized by L.A.-based AT&T engineers Bob Mathews and Gary Chow who discuss their work in the videos below: Read more

Report: iPhone 5 to have plastic/rubberized bezel, aluminum back, come Fall of 2012

BGR reports that the iPhone 5, slated to be released in the fall of 2012, would have a number of differences to the current 4/4S models.  The back will be aluminum and it will likely be surrounded by a plastic or rubberized bezel according to the report.

It will join the glass iPhone face with a new aluminum back plate. It will also cover a redesigned antenna system that surrounds the device, allowing Apple to build the rear case out of aluminum without having to use a large plastic insert above the antennas as the company does on its iPad 2 Wi-Fi + 3G.

The last we had heard from our contacts at Foxconn was that the iPhone 5 would be delivered in the summer of 2012 along with a slightly bigger screen at the same resolution, faster processor and redesigned form factor.
