Data v/s Signalling Traffic in Dongles and Phones

From a presentation by Peter Zidar in the Small Cells Global Congress 2012.

The above picture shows that even though the amount data traffic carried by dongles is much more than the amount of traffic carried by the mobile phones, the amount of signalling is far higher from the mobiles than that of dongles. This is mainly because the mobiles need to conserve the battery power and for this reason they disconnect from the network as soon as there is no need for exchange of data. Remember the Fast Dormancy issue in the smartphones? If not see this post.

Half Duplex Operation (HD-FDD) in LTE



It was interesting to hear the other day that there is an option for HD-FDD but it is still undergoing investigation and not standardised yet. From what I hear, operators are showing an interest and we may see it coming to an operator near us in the next couple of years.

Complete presentation below:



The advantages are obvious but probably the only reason this was not standardised actively is probably because then peak rates often quoted when promoting technology will be halved. The economy of scale is also important and we may not see this becoming popular unless many operators decide together to push for this.

5 videos on Augmented Reality

Looks like Augmented Reality (AR) is getting hot, just in time for Christmas. I wonder how many products will be sold based on AR. As I suggested in an earlier post, there may be 1 Billion users by 2020. Here are the videos:

Google's Ingress is an AR baased game:



Augmented Reality Book of Spells, Harry Potter experience:

Wonder when/ever it will come to a mobile near you.

LightBeam - Interacting with Augmented Real-World Objects in Pico Projections:



The next is a bit old but worth mentioning:

LuminAR from MIT


Finally, the science of Haptics will allows us to "touch" objects in a virtual world in future
