Elastic Telecom networks: a path towards cellular network virtualization

Over the last few months we saw two big announcements for Telecom consolidation in the US from the 3rd and 4th largest carriers. Is this a surprise or what? By all means it is not – I have been busy lately studying demand and supply curves for my micro-economics class (part of my MBA program) and viola – this all makes perfect sense! It is all due to the economy of scale – the larger the firm is the better it is able to supply the service needed at a better rate (meaning lesser dollars!). The one graphic that is always hurting the budgets for carriers is the ARPU distribution and the long tail economics.

So what will happen over the next few years is a change from selling voice and data for MNOs to service enablers. This requires several market plays which require – two main factors investment dollars and partnerships with several niche market players and this will allow MNOs to move into the VAS space. (more…)

Understanding the Signaling Tsunami

A recent development of Tekelec as the diameter supplier for T-Mobile LTE deployment has once again brought forth the discussion of control plane congestion and the operator readiness to address the issues. I have been working on this area for a long time and have seen the impact first hand on several customer outages. 3GPP and the Infrastructure vendors have come a long way since the days when the first smartphones changed the trend of user behavior and network congestion. It is not just an improvement on the ‘plumbing’ of smart pipes but the overall change end-to-end that has helped mitigate many problems, both from a signaling as well as performance. QOE (quality of experience) plays a big role in network planning and management today, as users now demand more from a handset/tablet than ever before. Signaling plane control gives the operator a better leverage and control over the various elements of the network that handles customer management and quality of service along with it…

Mobile Network Operators – retool, rethink & reinvent

 

 

 

 

Some time back I had an opportunity to speak with a technology pioneer, who helped introduce the best multi-media device – the iPhone on AT&T.  We went into the technical details of the experiences, the paradigm shift that never happened and the impending “data tsunami” that is happening as we speak. I have been blogging about this very data explosion for a long time now. I have been a traffic planner for the last 5-6 years of my career as a telecom engineer. I have seen the evolution of wireless networks from a voice centric GSM to a data centric-LTE, a shift in the thought processes of the big-iron telco companies that have shaped the way we communicate and interact with the world. MNOs (Mobile Network Operators) are in the cross hairs of technology evolution, data pipes are filling up faster that they can build. I monitor capacity at the Radio access side for an operator on a day-to-day basis, take my word for it – we ding your data experience at the cost o..
