A New Race is Looming [and it’s not 5G!]: Why China Can Win the Space Internet Future

China made headlines by launching an experimental satellite in low earth orbit to test 6G terahertz technology. This has the merit of elevating the 5G race debate to a higher level: 6G and space Internet. It comes at a time when several trends are taking shape, such as the evolution of 6G and the emergence of LEO satellites… Read More »

mmWave FWA vs. FTTH: Friend or Foe?

5G fanatics would lead you to believe that 5G will make fibre obsolete. So how real are their claims and how does 5G fixed wireless access (FWA) compare to FTTH on performance and RoI? To answer, we teamed-up with our partners at DTS to objectively assess the performance of fibre and millimeter wave (mmWave) FWA. We combined our… Read More »

Who Will Lead The Enterprise Private Wireless Network Market?

Enterprise private wireless networks been around ever since commodity base station silicon came to market in the mid-2000’s. 15 years later, deployments remain few and small. So the questions for investors are: are private wireless networks for real? How big a market is it? If I were to put money, where and how should I play this market?… Read More »

Does Open RAN Stimulate Innovation?

Proponents of open RAN argue that opening the RAN interfaces will stimulate innovation. They claim that non-interoperable interfaces allow incumbent vendors to lock out new innovative players and stifle the market. With a small number of incumbent vendors owning much of the market share, the pressure to innovate is low. Incumbents counter by stressing the optimized performance across… Read More »

A Perspective on Open RAN

There are over 800 service providers, but market power favors a handful of radio access network (RAN) vendors who dictate the tempo of technology. With the RAN accounting for around 60% of the network total cost of ownership, open RAN promises to change the balance of power in favor of services providers by reducing vendor power through more… Read More »

Clarifying the Confusing RAN Types and Nomenclature

Radio access networks have many descriptors that confuse the non-specialists. This includes open, virtual, cloud, centralized, distributed and cooperative RAN. Confusion is understandable because there are many inter-related aspects. Here, I outline the fundamentals elements that define RAN types and clarify the nomenclature. The Three Pillars of RAN Architecture, implementation and deployment are the three elements that define… Read More »

Network Sharing: Trends and Opportunities

Network sharing is one of those topics that makes economic sense, but often falters when it comes to adoption and implementation. Recently, I was asked about the prospects for network sharing given 5G capital investment requirements at a time of economic crisis. This is, of course, related to active sharing models where operators share the radio access network… Read More »

The Case for Network Automation: Application to Power Consumption

Integrated AI-based technology enables networks to adapt autonomously which helps operators optimize their service delivery to consumers and enterprises. As communication networks increase in complexity, operators seek to simplify operation and maintenance activities and reduce operating costs. Network automation could help operators achieve this objective. Automation is not a new concept: it has been around under different names… Read More »

The Cost Model for Enterprise Private Wireless Networks with Satellite Backhaul

The satellite and cellular wireless industries have long progressed along parallel tracks that rarely intersected [see here]. However, this could change in the next few years [see here]. Both satellite and cellular technologies are evolving to improve performance and reduce cost through technological innovations and new business models. In our recent paper, we analyzed the cost model of… Read More »

A Perspective on the Edge Computing Value Proposition

Last week, I had the opportunity to attend Edge Computing World where I participated in providing a workshop on the economics of the edge. Over the course of two and a half days of discussions common themes become evident. Here, I share a few observations on the edge computing value proposition and recent market developments that indicate what… Read More »

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 »

MNO Migration Strategies: An Update on Virtual RAN

Over the past week, I had the opportunity to get a full status update on Radio Access Network (RAN) transformation at the Telecom Infra Project (TIP) Summit in Amsterdam. I also had the opportunity to speak with a few service providers on the evolution of the telco network. Understanding the pain points and motivation of the carriers is… Read More »

Can Telecom Service Providers Monetize the Edge: Why the Telco Edge Cloud will be Far!

“Where is the edge?” is one of the most popular questions I heard at telco industry events. The answer often comes as “the edge is where it needs to be.” Some understand this to mean wide distribution of computing hardware that will make the telco edge cloud. Here, I will argue why wide distribution of computing is unlikely… Read More »

Can Telecom Service Providers Monetize the Edge: On-Premise Edge Computing

As 5G rolls out, edge computing is the hope of service providers to finally provide differentiated services. Service provides have two paths to monetize the edge: a consumer services path and an enterprise services path. The former plays to the strengths of the mobile service providers. The latter, enterprise path, is as an incremental opportunity that 5G could… Read More »

Is OpenRAN The Answer To Low-Cost Networks?

Is OpenRAN (Open Radio Access Networks) the path to saving costs in radio access networks? Vodafone seems to think it is as it trials the technology in its networks in the UK and Africa. Among Vodafone’s goals are: 1. Improve supply chain resilience; and 2. Connect rural communities using standardized, lower cost network equipment. This is good news… Read More »
