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 »

Demystifying Cloud RAN Architectures

Imagine a wireless service provider can provide service anywhere there’s Internet connectivity at the click of a button. All they need is a small remote radio connected to the Internet. The baseband modems no longer reside at cell sites, but are hosted in data centers where powerful commercial servers execute all the functions of todays base station baseband… Read More »

C-RAN and the True 5G

While people may debate what 5G will be, there are a few key facts that cannot be changed. These facts will shape what 5G will be. Based on this we expect that new winners will emerge who can capitalize on new trends through innovating new solutions. Therefore, aside from the hype that dominates 5G talk, the key is… Read More »

Edging Closer Towards Disruption in Radio Access Networks

In past articles [1, 2], I stressed that Cloud RAN is a disruptive technology. There are a few reasons for this, but I think that most critical reason is that Cloud RAN breaks open a pricing structure that’s been in use ever since the wireless industry was created. The current pricing model for base stations is based on a… Read More »

Mobile Edge Compute, The Threat of OTT and Changing Infrastructure Architecture

The threat of over-the-shelf services (OTTs) to wireless network operators is well established, but as of yet, there is no clear answer as to how mobile network operators (MNOs) can ward off the OTT threat. This is evident by eroding margins where many large MNOs are now standing in the 30% EBITDA margin range, down from around 50%.… Read More »

Cloud RAN Promises to Shape Future Wireless Networks

We have released our annual Cloud RAN report with new insights and analysis on the development of this market during 2014. Cloud RAN is certainly gaining in interest in the operator community. This is due to practical reasons related to cost savings that can be realized first by the process of centralization and then by the virtualization of… Read More »

Trends in Wireless Network Densification

One of the main trends in radio access network (RAN) is the bifurcation of systems that enable network densification. Today, mobile network operators have more options than ever before for the means of providing service to their subscribers. Alongside the evolution of wireless standards to provide higher spectral efficiency, vendors have unleashed a wide variety of radio access… Read More »

The Coming of Cloud RAN

The evolution of wireless communications has spawned many innovations but the cellular concept where base stations are dispersed to meet coverage and capacity requirements remains constant. This is about to change, sort of, if Cloud Radio Access Network (CRAN) architecture lives up to its vision. What makes CRAN such an interesting development is that it leverages advances in… Read More »

Cloud RAN vs. Picocells: The Need for Integrative Approach in Next Generation Network Design.

When it comes to deciding on deploying small cell base stations, one is faced with a few options. One option is based on cloud RAN architecture with remote radio heads connected through optical fiber to a central base station housing the baseband processing. A second option is that of a compact base station which includes both the radio… Read More »
