The LibreCellular project has reached the milestone of having a reference base station and related continuous integration (CI) subsystems completed with initial documentation, bringing it a step closer to its goal of open cellular communication for all. Launched in May last year, LibreCellular is an effort which aims to provide…

Build and basic documentation has been completed for the subsystems which will be used in the initial LibreCellular CI hardware configuration.

Lime Microsystems’ Andrew Back has shown off the capabilities of the upcoming LimeSDR Mini 2.0, building a private 4G LTE cellular network using srsRAN. “In this latest video we demonstrate a LimeSDR Mini v2 being used with the open source srsRAN software to create a private 4G mobile network complete…

The crowdfunding campaign for the LimeSDR Mini 2.0, an upgraded full-duplex software-defined radio built around a more powerful, flexible, and easily-sourced FPGA, has drawn to a close as a resounding success – and now the work of getting the hardware into peoples’ hands begins. The LimeSDR Mini 2.0 is based…

Since the project was announced last year we’ve suffered a number of setbacks due to circumstances outside of our control. For example, the company we planned to use for customised rack mount enclosures exited the market due to pandemic related issues. However, we are pleased to report that we are now making good progress and a long overdue update follows.

The LimeSDR-powered Portsdown digital TV transmitter project has been featured in the latest issue of The MagPi Magazine, showcasing how low-cost software-defined radio is being used by the British Amateur Television Club (BATC). “Now Dave [Crump, chair of the BATC] has completed Portsdown 4, using the more powerful Raspberry Pi…

The team at Enjoy Digital has been testing out the upcoming LimeSDR Mini 2.0, and has already turned it into a self-contained computer through the porting of the open-source LiteX system-on-chip to the on-board FPGA — using a fully-open toolchain. Announced last month, the LimeSDR Mini 2.0 is designed to…

Lime Microsystems has announced the LimeSDR Mini 2.0, an upgraded version of the smallest member of the LimeSDR range featuring a considerably improved field-programmable gate array (FPGA) – boosting its flexibility. Since its launch in 2017, the LimeSDR Mini – a single-channel full-duplex software defined radio built on the same…

Developer Wayne Campbell has released version 0.5.1 of rsadsb, a Rust-based ADS-B aircraft tracking system with a text-mode user interface — bringing with it its first support for LimeSDR devices. “Release v0.5.0 of rsadsb is now released,” Wayne writes of the launch. “Use any SDR supported by SoapySDR. If any…

Arved Viehweger is among a growing number of LimeSDR users turning their attention to X-Band satellite communications – receiving impressive high-resolution imagery from Russia’s ARKTIKA-M1 satellite. Launched in February 2021 as the first in the ARKTIKA constellation and serving as an Arctic monitoring system, ARKTIKA-M1 transmits at the lower end…

The UK government has announced a target of carrying 35 per cent of all cellular traffic over open radio access networks (open RANs) by 2030, alongside the planned retirement of 2G and 3G cellular – and LimeSDR technology has been selected for two key test-bed projects. “The mobile network operators…

Lime Micro products, including the LimeSDR family, are still being impacted by global component shortages and supply chain disruption – but Lime’s Ebrahim Bushehri has detailed how the company is working to overcome the issues. “While we’ve placed our orders and hope the supply chain settles down soon, we’re not…
