MNO Migration Strategies: Core Network Migration

In my previous article, I wrote about developments in virtual RAN, and indicated that the actual focus on the service providers is on core network migration strategies. The RAN receives high attention because it consumes more of the MNO capex and opex than the core network. This makes it a primary target for cost reduction. However, the core… Read More »

How the Concept of Cloud RAN has Changed.

Cloud RAN has reached the peak of the hype cycle, but I don’t expect the buzz to fade soon. My recent discussions at MWC2017 with many solution architects, vendors and service providers convinced me that Cloud RAN is foggy! This is because marketeers intent on capitalizing on the ‘Cloud’ trend took over the Cloud RAN concept. What started… Read More »

The Triumvirate Standoff and the New Telecom World Order

We are at a defining moment in the evolution of telecom. Forces are building across a fault line between service providers and Internet giants. Both sides appear to have reached a wall. It’s a matter of time before an earthquake reshapes the scene.  For service providers, the challenge lies in hard-to-scale rigid networks and a culture steeped in conservatism that… Read More »

Virtualize or Perish: The Software Transformation Challenge!

Telecom service providers are facing a challenging dilemma. While they are sitting financially comfortably, the forward-looking service providers know that they are required to implement sweeping changes in how they deliver services. Otherwise, they stand the risk of being relegated to commodity dumb pipe provider by visionary entrants with new service models. Thus, in facing the risk of marginalization,… Read More »

Why Are Telecom Service Providers Interested in Open Source?

Open source in telecom networks is an emerging concept that could disrupt the telecom value chain. Hardware solutions make up the vast majority of today’s telecom network infrastructure. In recent years, Network Function Virtualization (NFV) and Software Defined Networks (SDN) solutions began to appear in networks – a trend that will accelerate in the future. While virtualization provides a leap in… Read More »

Midterm Observations on the Telecom Industry.

Three events were held this past week that provided an opportunity to get a midterm pulse of the telecom industry: the MWC-Shanghai, 5G World and WBA Congress. Having attended the last two, I wanted to summarize a few observations: * The vision for 5G is converging; industry is aligning along common themes.  A few leading operators are racing to claim 5G capability… Read More »

5G: Revolution or Evolution?

Is 5G an evolution or a revolution? In an earlier article I said 5G is an evolutionary stage. Many disagreed: 5G is a revolutionary technology. But this is all a matter of perspective.  The evolution vs. revolution debate has largely focused on the air interface, or the ‘subscriber interface’: everyone wants to have fast wide-bandwidth connectivity. Naturally, it is the… Read More »

Are MVNOs the Next OTTs?

The wireless market in Canada is on the cusp of changes due to new regulations that open the market for a new breed of MVNO services. Full MVNOs are now possible: they will be able to have their own mobile network codes (MNCs) and provision their own IMSI numbers. Full MVNOs own their core network including all subscriber… Read More »
