As defined by the IEEE 802.3 Working Group, Auto-Negotiation is the process that Ethernet Devices use to identify and resolve the highest possible link between two devices. In simplified terms, Auto-Negotiation aids a user in finding the highest and most efficient operating speed for their system. Learn more about Auto-Negotiation in this overview paper written by Spencer Janelle, UNH-IOL Test Technician, CS, 2022.

The UNH-IOL acts as the 3rd Party Test Lab for the Ethernet Alliance PoE Certification Program. This Program works to identify PoE Powered Devices (PDs) and Power Sourcing Equipment (PSEs) that are based on IEEE 802.3 PoE specifications and have passed the Ethernet Alliance PoE Test Plan.

vIOLett® is a family of software packages used to test a product’s conformance to common protocols used in Time Sensitive Networking (TSN). There are vIOLett packages to test 1588, including Telecom and Power Profile, gPTP, MRP, MSRP, MVRP, and CBS. In addition, vIOLett is used to test products for the Avnu Certification Program, including Bridges, Pro AV or Milan Endstations, and Automotive devices. Learn how this tool can help identify areas of improvement during the development process and automate testing, reducing time to market and increasing your product’s reliability. In this presentation, industry experts, Bob Noseworthy and Daroc Alden, UNH-IOL, will review key features of vIOLett and what it means for your TSN testing.

The forthcoming Broadband Forum G.fast Certification Program, based on the ID-337 test plan, presents a number of unique challenges, including requirements for testing multiple CPEs (customer premise equipment) connected to a DPU (demarcation point unit) using a multi-pair cable. This white paper describes an approach to the construction of a copper cable plant...

The IEEE 802.11 family of wireless LAN protocols defines multiple physical layers implementations of which direct sequence spread spectrum (DSSS, 802.11b) and orthogonal frequency division multiplexing (OFDM, 802.11a/g) are currently the most popular. Market pressures are forcing the convergence of multiple wireless protocols into the same access device, and shortened product design cycles dictate rapid prototyping of new or enhanced protocols. The computationally intensive signal processing algorithms and high data rates associated with these protocols necessitate dedicated hardware implementation of some portions of the signal processing chain, yet allocating separate hardware resources for each of the standards would make the "universal access device" bulky and inefficient. Re-using the same software-reconfigurable hardware to handle different processing algorithms would enable an efficient, flexible alternative to current prototyping and implementation methods. In this thesis, the feasibility of using Software Defined Radio architectures as a prototyping tool for wireless LAN baseband signal processor implementations is explored. Signal processing architectures and algorithms for DSSS and OFDM protocols were developed in the Simulink and Matlab environments, and were then translated to VHDL hardware descriptions. A reference design for a OFDM transmitter was synthesized for implementation on a Xilinx Virtex II FPGA, and functional and timing simulations verified the design correctness.
