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…

A call for participation in GRCon24, this year’s GNU Radio Conference, has opened – ahead of the event itself taking place this September – and interested parties have until the 17th of June to get their abstracts in. “Packed with valuable content, the GRCon technical program is one of the…

Lime Microsystems has published the first details of LimeNET Micro 2.0, a radio front-end carrier board for LimeSDR XTRX and Raspberry Pi Compute Module 4 (CM4), which is used as the basis of the 5G network-in-a-box developed in partnership with Vodafone. The new LimeNET Micro 2.0 design brings increased performance,…

Lime Microsystems chief executive officer Ebrahim Bushehri rounded out 2023 with an appearance on the December Crowd Supply Teardown Sessions, talking through the history of the company and the LimeSDR – as well as the upcoming LimeSDR XTRX and a new chip dubbed the LMS8001. “Quite a few people have…
