Small Cells 'Terminology' and 'Comparison'


Here is AT&T's attempt in comparing the small cells. The above comparison is probably based on the assumption that LTE Small cells are not yet widely available. Once they are, then LTE can be put in for most columns in the Technology part.

Future mobile technology with Graphene



Some days back I attended an interesting talk where the speaker showed how Graphene will revolutionise the future mobile devices. Here is what Graphene is:



Another version:



A concept phone video from Samsung



And a Nokia demo from the last MWC that uses Graphene as a sensor and also opens the possibility of using other gestures except for touch

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.

Quick update on 3GPP Release-12 progress

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

Data growth from 0.6EB/Mo to 10.6EB/Mo by 2016 (18x)

A slightly old slide that I found while looking for some information but worth putting up here.

1 EB (Exabyte) = 1000000000000000000B = 1018 bytes = 1000000000gigabytes = 1000000terabytes = 1000petabytes

As we can see, Cisco predicts (and I agree) that the mobile data consumption will increase from 0.6 exabytes per month to 10.6 exabytes per month by 2016. What is really debatable is what actually is a mobile device and how much of this data will go through the operators network.

If for example a tablet contains SIM card but you use your own home/work WiFi. Does this qualify as a mobile device and is this data included. What if its exactly the same scenario and the device does not have a SIM card then would you say this is a mobile device? What happens when the operator allows you to use an Operator WiFi which is secured via login/password and you use the tablet without SIM card on an operator WiFi. Would you count this data, is the device considered as a mobile device.

The bottom line is that data usage will continue to grow but probably not on the mobile networks. WiFi would be a prime candidate for offloading, due to it being mostly free (or costing much less - except in the hotels). Some of the recent pricing by the operators make me feel that they do not want the users to use their network for every day use, only for important work.
