First tagged release of Lime Suite NG, the next generation driver stack, plus collection of plug-ins and utilities for the LimeSDR family of software-defined radios. And a new package repository.

Lime Microsystems has announced a new revision of the LimeNET Micro 2.0 which adds compatibility with the newly-launched Raspberry Pi Compute Module 5 – delivering at least twice the performance and unlocking support for improved cellular capabilities. “We are delighted to announce that LimeNET Micro 2.0, the eminently compact 5G/4G…

New cellular software stack and base station design. A new cellular software stack configuration has been published, which is much more feature rich and provides support for VoLTE and SMS, along with a new design for base station hardware. PyHSS, Open5GS and Kamailio IMS Deployment tooling, container images and configuration…

Lime Microsystems has announced a new entry in the LimeSDR XTRX family, a front-end adapter which combines a 2×2 multiple-input multiple-output (MIMO) radio-frequency front end (RFE) with a full-size PCI Express carrier: the LimeFEA mPCIe. The LimeFEA mPCIe is designed to accept the LimeSDR XTRX mini-PCI Express software-defined radio module…

Don Pivo is single-handedly bringing back the vintage “Magic Eye” indicator tube, designing modern digital replacements in 3D-printed housing – with his latest being an LCD-powered alternative to the 6U5. “Tuning indicator tubes have hardly been manufactured the last 50 years, and some types are scarce, e.g. the 6U5,” Don…

Software-defined radios represent “the next level of shortwave radio listening,” says convert James Careless – writing a piece espousing the technology’s benefits for Future Publishing’s Radio World magazine. “Where have these things been all my life,” James rhetoricises after being introduced to the world of software-defined radio systems. “There is…

The LibreCellular project, which aims to provide an end-to-end open-source technology stack for cellular networks, has celebrated another major milestone with the development of a new, highly-versatile radio-frequency front-end (RFE) offering 2×2 Multiple-Input Multiple-Output (MIMO) operation. “This is designed to be connected to an SDR and provides uplink and downlink…

The srsRAN 4G fork with native LimeSDR hardware support has received a long overdue update, and a new RF front-end has been developed which provides a highly convenient solution for those building base stations, both of the small cell and wider coverage type.

Boston-based Wavelet Lab has launched a high-performance software-defined radio system dubbed the xMASS SDR, using Lime Micro LMS7002M-based modules to deliver 8×8 multi-input/multiple-output (MIMO) connectivity – or up to 16×16, by linking two boards. “xMASS SDR is a modular, high-performance MIMO transceiver optimised for industrial, academic, and advanced software-defined radio…

Orders for the new LimeNET Micro 2.0 all-in-one software-defined radio platform, powered by the LimeSDR XTRX and Raspberry Pi Compute Module 4, are to open soon – in the form of a “Developer Edition” kit. “LimeNET Micro 2.0 DE (Developer Edition) is a modular radio platform that leverages the Raspberry…

Next generation software-defined radio (SDR) driver stack brings numerous improvements.

QRadioLink developer Adrian Musceac has written up a project to build a working though self-admittedly “limited functionality” software-defined Digital Mobile Radio (DMR) Tier III trunked radio base station transceiver powered by a LimeNET Micro or LimeSDR Mini. “It seems desirable to study the properties of a trunked radio system and…
