10BASE-T1S/L Connects sensors in cars and buildings

June 27, 2024

In 2019, IEEE published 802.3cg, which added clauses 146 and 147 to its Ethernet 802.3 standard, which created 10BASE-T1S (short reach) and 10BASE-T1L (long reach). These two Ethernet flavors can serve vehicles and industry, respectively, where few wires take priority over high speed. Automotive Single-Pair Ethernet (SPE) 1000BASE-T still has a place in vehicles for infotainment and assisted driving. Many automotive and industrial sensors don’t need high-speed links but need data and power.

The automotive industry has shown interest...

March 25, 2024

Developing and deploying a laboratory infrastructure to support testing 5G and open radio-access network (Open RAN) systems can present a daunting and complex task. Prior to Open RAN, this task was only possible by engaging directly with the large network system vendors. Since then, several open-source projects and organizations have developed materials based on 3GPP and O-RAN Alliance specifications. Those tools and resources make it possible to create a complete 5G deployment, spanning from the mobile core to RAN, providing...

Opening Up the Network

November 7, 2022

Revolutionary Transformation Doesn’t Occur Overnight

This year, we have seen a continued shift to agile network service delivery from Proof of Concept to real-world deployments and a multi-service broadband network. Therefore communication service providers (CSPs) are under pressure to upgrade and transform their networks, pushing to support services beyond simply delivering network connectivity. With an increasing number of connected devices, CSPs are tasked with supporting these high-bandwidth applications and services with a network that offers both Quality...

The road to lower costs & improved customer satisfaction is built on effective Wi-Fi testing

October 21, 2021

By Lincoln Lavoie, Broadband Forum Technical Chair

Poor signal, coverage, and performance – these Wi-Fi ‘experience killers’ within the subscriber network have been exacerbated over the past year or two with the switch to home working and schooling.

A common view is that these components are part of the overall broadband offering. Take slow loading time and the speed of access – the common perception amongst customers is that, when these components fail or falter, it means that...

June 2, 2021

In mid-2020, the NVMe Organization released the first revision of the Zoned Namespace specification (ZNS). This new specification has received a lot of attention, with promises of longer living drives that achieve higher performance under certain conditions. Since then, a number of companies have published roadmaps that include products with ZNS support. In this article, we'll review the significance of this specification and what ZNS drives are good for.

First, this specification is significant because it brings a new...

June 2, 2021

Developing and implementing testing for Wi-Fi shares many of the same challenges you would expect in testing any wireless or RF technology. With the new TR-398 Issue 2 test plan, a strong focus has been on creating a repeatable set of test procedures, setup, and configurations. It’s been necessary to ensure the testing can produce repeatable pass or fail results from absolute performance requirements.

This focus sets the TR-398 testing apart from much of the other...

Power over Ethernet (PoE), is a technology for ethernet end devices that provides the ability to transmit and receive data, in addition to receiving power over the same cabling. It defines Power Sourcing Equipment (PSE) which usually takes the form of an Ethernet Switch, and Powered Devices (PD) which are the end devices in need of power and vary greatly depending on their intended application. PoE has greatly simplified the design and installation of these applications

April 8, 2020

To deliver on the promise of 5G, which sometimes seems like everything to everyone, network operators will need to augment their existing network architectures, addressing some flexibility brought into existence with the new 5G technologies and designs. Overall, 5G brings numerous changes to the mobile network, its architecture, and the equipment used to construct it. 5G is so much more than a wireless technology. Indeed, it’s producing significant changes on the wired network, particularly in the fronthaul, the portion of...
