Software-Defined Radio

I get a lot of interesting  things in my inbox. Here are three of the latest……..Dan

SDR Workshop using the ADRV9002 Integrated RF Transceiver and GNU Radio

Attendees of this webinar will learn about:

• The ADRV9002 Wideband Transceiver
• An introduction to development tools for ADRV9002, including the DataStorm DAQ FPGA platform
• How to setup the software environment for ADRV9002 applications on a Windows PC
• A Demonstration of GNU Radio working with DataStorm DAQ and the ADRV9002

AT8KLH – Kappu lighthouse Expedition

I love  lighthouses, as you know. Here’s a video on the activation of one of India’s 185  lighthouses.

NIST public safety communications software

The National Institute for Science and Technology does a lot of research on emergency communications, and its software is available for download. On this page, you’ll find software they’ve developed in their research, including:

• Public Safety Communications Simulation Tool. The psc-ns3 repository supports research on public safety communications and beyond. The Long Term Evolution (LTE) module has been extended to support device-to-device (D2D) and UE-to-Network relay communication and a new psc module has been added containing a Mission Critical Push-to-Talk (MCPTT) application, a new HTTP application, and a UAV mobility energy model. Ongoing work includes New Radio and V2X extensions.
• Use Case Reference Model Database. NIST’s Atlas is a use case reference model database that explores how to provide meaningful cyber security guidance for public safety mobile applications. This database provides information on the use and security of software by proposing use case scenarios as a proxy for the system at the center of the NIST Risk Management Framework.
• Mission Critical Voice Quality of Experience Mouth-to-Ear Latency Measurement Method. The purpose of this software is to measure the mouth-to-ear (M2E) latency of a push-to-talk network. M2E latency characterizes the time between speech input into one communications device and its output through another. M2E latency has been identified as a key metric of quality of experience (QoE) in communications. NIST’s Public Safety Communications Research group developed this software to measure and quantify the M2E latency of Push To Talk (PTT) devices.
