Outside Plant and Broadband Public Policy

Here's some interesting insights from the Digital Britain interim report. The civil engineering work required to deploy next-generation access (NGA) infrastructure is a significant part of the business case for a major broadband deployment project, and some estimates put it as high as 80 percent of the overall cost.

Although it is not the only remedy, providing access to existing ducts, and therefore reducing the cost of deploying fiber for Communication Providers (CPs), is one solution that may lower the barriers to entry for CPs, and therefore support meaningful service provider competition.

Ofcom commissioned Analysys Mason to survey a number of UK cities and towns to assess the level of occupancy of the telecoms duct infrastructure, and to investigate the practical issues that CPs may face if deploying new fiber cables -- using the incumbent service provider's existing infrastructure.

The main objective of the survey was to make an indicative assessment of the duct infrastructure to help Ofcom determine whether or not duct access was a viable option in the UK for CPs to deploy new fiber cables in access and backhaul networks.

The key conclusions of their study are:

- Just over half of the duct ends surveyed have at least 42 percent of unoccupied space, 22 percent of surveyed duct-ends were full, and 26 percent of surveyed duct-ends were empty.

- Unoccupied space in the duct infrastructure network is not evenly distributed across the different sections of the network, and is more likely to be congested in the access part of the network than in the backhaul network.

- Unoccupied space in the duct infrastructure network is not evenly distributed across the different towns/cities, and cities where recent civil engineering work was carried out are more likely to have more available space.

- Unoccupied duct-end space will not directly translate into usable duct space for a CP willing to use the ducts, for a number of related reasons -- explained in the report.

How Data and Analytics Drive Business Growth

Senior executives in the world’s largest and most complex organizations will develop the insights required to achieve lasting Digital Transformation. Gartner has identified a model for digital business growth that binds together data, analytics, technology, and forward-looking transformation capabilities. The Gartner Research Board said that data and analytics (D&A) leaders are uniquely positioned to drive this strategic organizational change that will make their companies behave like 'digital native' leaders.  "The most advanced and successful D&A leaders are driving new opportunities to use digital capabilities – often data and analytics products – to capture value. Those opportunities should directly connect to the business priorities," said Mario Faria, vice president at Gartner . Digital Business Market Development At the same time, some leaders are using digital and D&A to create whole new business models. These leaders – which Gartner named the CxO

Anywhere, Anytime Workplace Demand for SASE

The ongoing adoption of flexible working models within the enterprise market has significant implications for typical IT organizations that must now support knowledge workers and front-line employees that operate outside the corporate network perimeter. The global COVID-19 pandemic created IT networking and security challenges. The expansion of the distributed workforce, an increasing reliance on cloud computing infrastructure, and the requirement to securely connect online employees -- wherever they choose to work, at any given moment in time. Legacy IT solutions that have rigid network underlays and a requirement for on-premises infrastructure cannot adequately deal with these trends. This 'Anywhere, Anytime Workplace' led to demand for new Secure Access Service Edge (SASE) solutions, with networking and security delivered as-a-service. Anywhere, Anytime Workplace Market Development   Although converging networking and security capabilities offer enterprises a promising solut

The Metaverse Raised Virtual Reality Interest

After years of slow growth and limited use cases, the Virtual Reality (VR) market is now forecast to grow significantly over the next five years. Consumer interest in VR games and media continues to grow after the COVID-19 pandemic accelerated activity. At the same time, the need for employee enablement and immersive content within the enterprise environment remains strong. According to the latest market study by ABI Research, over 90 million Head Mounted Display (HMD) shipments in 2027 will drive total VR market revenues to reach over $95 billion across hardware, software, and services. Virtual Reality Market Development "The virtual reality market is no stranger to false starts, with identifiable efforts in VR dating back to the 1980s and 1990s. While the technology never found purchase results, the increased capability of VR hardware combined with the demand for immersive content in numerous markets, presents a significant opportunity," says Eric Abbruzzese, research direc
