As with traditional IT networks, Operational Technology (OT) networks are undergoing a digital transformation process of their own. The goal is to improve productivity, efficiency, up-time, and flexibility through better monitoring. To do this, online sensors and connected systems are replacing traditional serial connections, proprietary protocols, and programmable logic controllers to better manage and control industrial environments.

Nokia expands WING with 5G IoT capabilities

Article | March 18, 2020

In a recent release, Nokia announced that it is evolving its Worldwide IoT Network Grid (WING) managed service to add 5G and edge capabilities. This upgrade reportedly facilitates operators in offering 5G IoT services without having to invest in global infrastructure. WING is designed to help operators capture early IoT market share without having to make investments in infrastructure because of a pay-as-you-go business model designed to allow the scaling of 5G IoT services faster and more cost-effectively. With Nokia WING, operators will be able to leverage new business models and tap into industries such as connected cars, critical public services, and real-time industrial monitoring and control, as well as remote healthcare, the company said. Nokia has invested in a 5G WING lab in Dallas, Texas, to which operators around the globe can connect and begin testing 5G IoT use cases.

How service providers can unlock the coveted SME market

Article | June 7, 2021

For communications service providers, questions still loom over how 5G will be monetized. Many have voiced the view that the enterprise segment is where 5G will make its money, with potential use cases across a breadth of verticals including the automotive, manufacturing and utilities industries to name a few. However, if service providers focus more on delivering 5G business use cases to small and midsized enterprises (SMEs), this market segment could prove to be a fruitful source of revenue. As 5G deployments continue to roll-out globally, CSPs are focused on deriving value from projects and partnerships with large multinational enterprises. And they are eager to do so quickly to assure payback from their $1trillion investments in the next generation network. However, are CSPs blinkered in their approach to generating ROI from 5G? Are they limiting themselves by focusing too much on a small segment of the enterprise market, that to date has limited CSPs' involvement in early 5G projects, reducing them to mere providers of connectivity?

FUTURE-PROOFING 5G ARCHITECTURE WITH OPEN-RAN

Article | May 19, 2021

The RAN (Radio Access Network) architecture for mobile networks includes a remote radio unit (RRU) located at the top of a cell tower, which communicates with a baseband unit (BBU) at the base of the tower. The hardware and communication interfaces are owned by a specific vendor, and its software-driven functionality is tightly coupled within the hardware. Traditionally, this has worked well for mobile network operators (MNOs). However, there are several drawbacks to consider – for instance, upgrading or changing the wireless network demands physical hardware replacements throughout the network, which is cost-inefficient, labor-intensive, and time-consuming. Furthermore, the equipment and interfaces that connect the hardware are owned by the vendors that originally supplied them, which locks MNOs into existing relationships with them.

Accelerating the Evaluation and Deployment of uCPE-Based SD-WAN Solutions

Article | February 28, 2020

Unless you’ve been living on an Internet-free desert island for the past couple of years, it’s been hard to escape all the industry hype around Software-Defined Wide Area Networking (SD-WAN). While the business benefits of adopting SD-WAN are significant, there’s no denying the fact that evaluating and then deploying potential solutions is hard: typically, the solutions that deliver the best Return on Investment (ROI) involve products from multiple vendors, leading to complex integration and testing. A recently-announced software evaluation kit addresses these challenges, providing a pre-integrated open-source SD-WAN solution that runs on multiple white-box hardware platforms, all ready for a quick, efficient start to putting together a multi-vendor SD-WAN deployment.
