Optimizing Mobile Web

16 Feb 2012 02:51 No comments
    Not all apps on our smartphones are created equal, just like how not all network technologies work the same. Some perform great and some not as much, but do we know how each one differs from the other? The other day I was discussing mobile applications with my wife who is a mobile [...]

28 Jan 2012 16:40 No comments
With Super Bowl XLVI around the corner, as a wireless engineer I always wait with bated for the performance of the network. How many calls did we drop?

29 Dec 2011 19:51 No comments
  via  Like most guys I love my car (after my gadgets & my Triumph) and like most of you I drool at the prospect of getting a car that will talk to me and connect all the pieces together. As a child, the first car that caught my imagination was Herbie (the wonderful little Bug), [...]

I am not an early adopter of technology, though I am one of the gears that drive the engine of change for wireless technology. But I read most of my news, books, email, Youtube – 80% of the time today on my Cellphone or iPad (love Flipboard & Zite!) which runs on my wireless carrier.  [...]

Battery life of Mobile devices!

LTE (Pico cell) closed loop power control would definitely restrict UE power and give longer battery life.    

Unlicensed Spectrum and Wireless Networks

18 Nov 2011 01:15 No comments
