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:

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

Four Options for Traffic Offloading

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.
