Reducing CSFB Timing with RRC R9 Optimisations
While in the initial testing CSFB timing used to be between 6-8 seconds, most Rel-8 phones can complete the CSFB procedure between 4-4.5 seconds. Unfortunately this is still a lot in terms of signalling. To reduce this in Rel-9 there is a simple optimisation that has been done.
In the RRC Connection Release message, there is a possibility to add UTRAN/GERAN System Information messages. In the picture above, I have only shown UTRA System Information but a similar picture can be drawn for GERAN.
Once all the Mandatory SIB's are sent to the UE then it can immediately camp on without the need to read any other additional system info. This will reduce the CSFB time between 1-2 seconds.
The lesser the CSFB time, the better the Quality of end user experience

Nice Pie Chart on different Android Devices
Click to enlarge
I guess Pie charts like these can convey more information then writing about the percentages of devices sold. Maybe we should use them more often to represent information.

Secure Wi-Fi for Large Scale Events and Arenas
Interesting presentation from Logica on Secure WiFi. The resolution of this presentation is low for security reasons as well, I guess.
