Cable MSOs Add Capacity with Node Splits

Cable operators have traditionally regarded node-splitting -- the addition of more capacity to existing cable network nodes -- with fear and loathing. Now, according to ABI Research, some of them may have to bite the bullet. But for those providers offering advanced services such as high-definition TV, there are rewards as well.

Some cable operators, following demand, have built out their networks piecemeal, without much regard for the long-term capacity of the nodes which form an integral part of the cable plant. The result: in some neighborhoods -- particularly in North America and Western Europe, where the strong growth phase of cable networks is over -- nodes are unevenly distributed relative to population. That in turn means some customers are getting better service than others.

"Cable companies want to distribute nodes -- each serving a number of households -- as evenly as possible throughout their networks, so that there are similar numbers of homes being supported on each node," says vice president and research director Stan Schatt.

"But for some operators, the imbalances are approaching ridiculous levels. Node balancing is both expensive and labor-intensive, however, and many operators have procrastinated, hoping for some way out of this bind. ABI Research believes the time is approaching when many of them will realize that they have no alternative."

A new ABI Research study forecasts that by 2012, node shipments will grow to 9,200 in North America. Worldwide, demand is expected to peak at 163,000 in 2010 and then taper off to 142,000 in 2012.

"These operators are in a position of having to spend a good deal of money on node balancing," adds Schatt, "but for those offering advanced services, it will facilitate expansion of high-definition channels and other bandwidth-hungry technologies."

I believe that with less emphasis being placed on the viewing of traditional linear TV channels, all pay-TV service providers will need to adapt their forward-looking definition of capacity planning to incorporate increased video on demand (VoD) applications.

As an example, if subscribers hardly ever view a particular program live, then delivery to their DVR could be timed to coincide with when the distribution network has less capacity demands. The intelligent assignment of available bandwidth would therefore help to alleviate capacity constraints. Perhaps there are network enhancements, as alternatives to node splits, that can automate the scheduled and dynamic assignment of available distribution network resources.

Climate Change Benefits from The Circular Economy

The COP26 Summit (in Glasgow, Scotland)  brought parties together to accelerate action towards the goals of the Paris Agreement and the UN Framework Convention on Climate Change. Meanwhile, the circular economy is a key sustainability strategy adopted by industry leaders in their efforts to achieve progress. While the circular economy is still in its infancy in terms of data and metrics, it's a growing phenomenon where technology sectors -- such as the Internet of Things (IoT) for asset tracking -- are set to grow rapidly within the next five years. Global technology intelligence firm ABI Research forecasts that the world will achieve over 10.5 percent circularity by 2030, as sustainability efforts and incoming legislation start to take effect. Circular Economy Tech Market Development "The circular economy is an often-misunderstood concept that goes much further than waste management and can become a blueprint for cities. It is a movement away from our take-make-waste economy

Business Technology for The Anywhere Workspace

The COVID-19 global pandemic fueled the trend of pushing executives outside of their comfort zone, while government-mandated lockdowns required their knowledge worker employees to work from home. Companies that previously avoided 'Flexible Working' models were forced to embrace the pervasive trend in a matter of weeks, as new remote working policies became a CHRO standard practice. As we enter 2022, more employers will empower their key employees to work wherever they desire and engage with customers whenever and however they prefer. Moreover, the ongoing transformation to an 'Anywhere Workspace' will drive strategic IT spending and advance cloud-based SaaS adoption. Business Technology Market Development Global enterprise IT spending is projected to total $4.5 trillion in 2022, an increase of 5.5 percent over 2021, according to the latest worldwide market study by Gartner. "Enterprises will increasingly build new technologies and software, rather than buy and imp

Guidance for Leading Digital Business Value Creation

In today's environment where business technology is a key enabler of competitive advantage, CEOs need to be sure that someone is confidently leading digital business growth across the organization. The default is the Chief Information Officer (CIO) role. According to the latest worldwide market study by Gartner, in order to accelerate business value creation, CIOs and other IT executives should focus on three key areas -- leading from anywhere, nurturing connections, and reaching beyond. Mbula Schoen, senior research director at Gartner , said that as organizations continue to emerge from the disruption of the COVID-19 pandemic, CIOs and IT executives will need to generate value in fundamentally new ways. Business Technology Market Development Gartner forecasts that by the end of 2022, the share of knowledge workers working remotely will increase to 47 percent -- that's up from 27 percent in 2019. However, simply moving from onsite to remote is not the destination but merely a
