Facebook's Signaling Chatter Grows Louder

By Lindsay Newell, VP, Marketing Networks & Platforms Group, Alcatel-Lucent

Our last few blog posts on mobile intelligence focused on how changes to devices and their operating systems can affect both the user experience and the network in positive and negative ways as detected using the 9900 Wireless Network Guardian. Today we will explore the impact of changes introduced by a new version of a popular application.

Last year, Facebook released new versions of their mobile app for Android and iOS. Prior to the new release, Facebook signaling and airtime already accounted for 10% and 15% of the overall load on 2G/3G networks, respectively.  As users around the world updated and started to use this new version, we quickly noticed a dramatic increase of almost 60% in the signaling load and 25% in the airtime consumed by the Facebook application.  During the same period, the number of Facebook users increased by only 4%.   Clearly, it is not the swelling of Facebook’s community that intensified the load, but rather the introduction of new Facebook features for mobile users and underlying platform changes.
