"This proof of concept opens the doors to many short-range RADAR applications using the emerging low power and low cost SDR technology," says student Victor Cai of his experimental software-defined radio project built around a LimeSDR Mini and GNU Radio.
"Whether you’re a Ham radio operator, a network engineer, a mobile base station designer, a security auditor, or some other variety of SDR enthusiast," Yian IT says, "RadioSlate lets you do your thing, even if that thing requires you to go outside and walk around, get unusually close to transmitters and receivers, keep one hand free for other tasks, or manage all of the above without drawing undue attention to yourself."
LiFi or light fidelity is similar to WiFi and as the name suggests, instead of using radio waves, utilises visible, IR or UV light for communications. The new development kit from Hyperion Technologies is based upon the LimeSDR USB and uses two of these together with optical transmitter and…
Demonstration of a bachelor thesis project is given where a LimeSDR Mini is used in a system designed to prevent UAVs from entering an unauthorised area.
"Kimera can capture any camera connected to your computer," Cruz explains, "hardware encode it with any codec available (e.g. HEVC, AVC, AV1), and transmit over TCP, UNIX Socket, or this GNU Radio Transport Layer."
"The ME1130 training kit is a versatile system that can be configured to work as an offline system for simulation or as a real-time system for over-the-air transmission and testing," says DreamCatcher of the training kit, which features a LimeSDR USB and LimeSDR Mini for base station and spectrum analysis operations.
"The TIP community has had a significant impact on opening up telecom networks to lower costs, increase innovation, and help operators extend the benefits of high quality connectivity to more communities across the world," says Tenorio. "As Chair I will champion continued innovation and the opening up of supplier ecosystems to more competition."
GPUs are increasingly being used in applications outside of graphics and have been popular for some time in both high performance computing (HPC) and machine learning. Thanks to technologies such as the CUDA parallel computing platform from NVIDIA and the Numba high performance Python compiler, the barriers to using GPUs are being lowered all the time, enabling their blistering performance to be harnessed in ever more compute-intensive applications.
Pre-built operating system image - now compatible with all Raspberry Pi models plus the LimeNET Micro - aims to make it as easy as possible to get started with software defined radio on single-board computers.
