FWA can deliver higher data rates, but consumer adoption is dependent on a CPE device’s performance At the recent Test and Measurement Forum, LitePoint’s Product Manager Khushboo Kalyani gave a presentation outlining some of the value propositions of Fixed Wireless …

Impacts to the radio frequency environment isn’t the first aspect that comes to mind amid the ongoing shift toward cloud-native, disaggregated networks. But that’s not to say there aren’t any, and according to Regis Lerbour, VP of product for network …

The three (not so) easy pieces of 5G service assurance—orchestration, the edge, and end-to-end visibility Here’s a hypothetical: A manufacturing enterprise has looked at its options for gaining production efficiencies and opted to use various video analytics backed by private …

When bringing CT to live networks, it’s important to build and design for this framework from day one The move towards continuous integration and continuous delivery/deployment or CI/CD and continuous testing (CT) is part of the telecom industry’s larger push …

CI/CD is a software development principle that introduces automation into the entire lifecycle software development Continuous integration (CI) and continuous delivery/deployment (CD) — together referred to as CI/CD — is a software development principle or method in which automation is …

Midband spectrum is often referred to as having the right mix of performance capability and coverage for mobile networks, particularly 5G, when compared to low-band or millimeter-wave spectrum. As midband spectrum is being deployed, what impact is it having on …

Testing and deployment at cloud scale needs cloud-style automation and orchestration. There’s already been gallons of ink spilled in service of lecturing Communication Service Providers (CSPs) on the importance of adopting cloud-native business processes and technology as they pivot to …

Challenges to 5G test strategies in product and device testing can be mitigated using thoughtful testing and automation.

As network operators navigate a multi-pronged transformation that encompasses 5G, fiber proliferation, increasingly cloud-based and virtualized networks, one of the challenges that they face is that of radio frequency interference. RF interference is not a new issue in wireless networks, …

“The network of the future is a cloud of a cloud of a cloud,” said Viavi Solutions CTO Sameh Yamany 5G is opening up support of new verticals and use cases via a more flexible network — but it also …

Service providers are taking multiple routes to architecting and/or opening their 5G networks. Some are handing them off to hyperscalers, either for specific applications or more broadly. They face the decision of what data to keep under their own control …

‘We are trying to drive the notion of QoE,’ says AT&T’s VP of network analytics and automation “In 5G, our focus is the customer experience. We are trying to drive the notion of QoE,” says Raj Savoor, vice president of …

 3G networks are being turned down, 4G is at the heart of most cellular networks around the world, and 5G is gaining ground across the globe.   As quickly as 5G has dominated industry discussions and marketing, however, it still isn’t …

The European Telecommunications Standards Institute (ETSI) is continuing its ongoing series of Plugtest events to test the interoperability of mission-critical communications services, including mission-critical push-to-talk (MCPTT), mission-critical data (MCData) and mission-critical video (MCVideo). The most recent Plugtest, ETSI’s sixth, was …

“Operators who have been rolling out 5G NR networks for some time have the coverage advantage,” SRG says For some time, Dish Network has been promising a beta launch of its much-anticipated 5G network in Las Vegas, amid delays. That …

Cognitive networks apply data intelligence to end-to-end data flows The latest generation of cellular, 5G New Radio, has three primary characteristics: multi-gigabit per second throughput, ultra low latency and very high reliability, and support for massive numbers of internet of …

A data-first approach to operational excellence As operators consider any type of artificial intelligence- or machine learning-based network automation projects, “Everything comes back to data,” according to Damion Rose, senior product manager of mobile signaling and data analytics at BICS. …

Adding intelligence to the radio access network is the focal point of AI and ML adoption by telecom operators and their vendors. And given the increases in traffic and complexity brought about by the advent of 5G, alongside the move …
