Mobile Broadband Speeds: How is 4G different from 3G?

I wrote this answer on Quora and as of yesterday there were 20+ upvotes. So here is an embed for the same:

Quick Introduction to LTE-Advanced

An article written by me for the Mobile Europe magazine where I try and explain LTE-A without going in technical details. This also includes the state of market on who is doing what.

Evolution of 'Internet of Things' to 'Internet of Everything' #IoE

Will the 'Internet of Humans' and the 'Internet of Things' (IoT) evolve into 'Internet of Everything' (IoE). This is certainly what Dave Evans, the Cisco Futurist thinks. This is from his blog:


From the Internet of Things (IoT), where we are today, we are just beginning to enter a new realm: the Internet of Everything (IoE), where things will gain context awareness, increased processing power, and greater sensing abilities. Add people and information into the mix and you get a network of networks where billions or even trillions of connections create unprecedented opportunities and give things that were silent a voice.

As more things, people, and data become connected, the power of the Internet (essentially a network of networks) grows exponentially. This thinking (“Metcalfe’s law”) comes from Robert Metcalfe, well-known technologist and founder of 3Com, who stated that the value of a network increases proportionately to the square of the number of users. In essence, the power of the network is greater than the sum of its parts, making the Internet of Everything, incredibly powerful.

Virgin Media's offering on SCaaS

I have blogged about FaaS in the past that is now undergoing trials. I also blogged about SCaaS from our last Cambridge Wireless event that shows the seperation between the operator and the services provided by Small Cell service provider. In the recent Small Cells Global congress, Kevin Baughan from Virgin Media gave an interesting talk on their recent trials. This is the architecture they are proposing.  

They would do site acquisition and maintenance, provide the backhaul and power, any mobile network operator (MNO) can come and put their small cell on the furniture to provide the coverage. I am not sure if multiple operators would pitch for the same sites but I wouldnt think of this as a problem as I am sure there would be multiple sites available in the same location.

A real killer from Virgin media could have been that it does something similar to Free, the French mobile operator that has apparently got Femtocells inbuilt in the set top boxes.

We will have to wait and see how many operators are willing to have third party host their small cells and how many.

CSFB Performance

Here is another presentation from Qualcomm from the '4G World'.

CSFB Performance from Zahid Ghadialy

With regards to SI Tunneling mentioned in the presentation, I found the following in another Qualcomm whitepapers:


With Release 9 Enhanced Release with Redirection—SI Tunneling, the device follows 3GPP release 9, where SIB information can be tunneled from the target Radio Access Network (RAN) via the core network to the source RAN and be included in the redirection message sent to the device. This can avoid reading any SIBs on the target cell. 

The predominant solutions deployed today are based on Release 8 Release with Redirection — SIB Skipping, in order to achieve good call setup times, good reliability, and simplify deployments. It is anticipated that Release 9 Enhanced Release with Redirection will be deployed in the near future. At this time, there is not as much push for handover-based CSFB since both Release 8 Release with Redirection—SIB Skipping and Release 9 Enhanced Release with Redirection—SI Tunneling have largely addressed any call setup time issues that may have existed with the Basic Release with Redirection solution.

I have blogged on this topic before, here.
