The British Amateur Television Club (BATC)’s Portsdown digital TV transmission platform has received an update, bringing with it drop-in support for the using the new LimeSDR Mini 2.0. “The previous facilities that worked with the LimeSDR Mini V1 and the LimeSDR USB now also work with the LimeSDR Mini V2,”…

Vodafone has shown off a palm-size 5G base station, powered by a Raspberry Pi 4 single-board computer with Lime Microsystems software-defined radio technology inside – in an effort to make private cellular networking and edge computing more accessible. “We looked at what Raspberry Pi did for computing, in terms of…

Backers of the LimeSDR Mini 2.0 have started to receive their hardware, following delivery of the first production batch – with enough to fulfil all existing orders and more. “The first batch of LimeSDR Mini 2.0 boards have been manufactured, tested, and delivered to our UK headquarters,” Lime Micro’s Andrew…

LimeSDR users have been showing off their satellite imagery successes on social media, capturing data from NASA’s Terra, Suomi-NPP, NOAA-20, and more and decoding it to great effect. “Here it is,” writes Peter Kooistra on Twitter, while sharing images including the one adorning this newsletter. “My first Terra with…

It’s been a bumper month for the LibreCellular project with not one but two major milestones to celebrate: The first end-to-end test of the continuous integration (CI) system and the first basic service network offering connectivity to real-world 4G Long Term Evolution (LTE) devices. “We are pleased to report that…

We are pleased to report that the next milestone has been achieved and it is now possible to set up a network to provide basic service.

We are pleased to report that the next milestone has been reached, whereby the srsRAN software is automatically built and deployed to a base station, together with eNodeB and EPC configuration, following which an end-to-end test is completed when a modem attaches to the network and a successful ping completes.

The LibreCellular project has reached another milestone with the development of a low-cost 1,800MHz medium power amplifier design targeting 4G Long Term Evolution (LTE) Band 3. “While suitable low power RF amplifiers are available at a modest cost, as the power output increases to a watt or more the cost…

Initial version of a low cost 1800MHz power amplifier design completed and tested. In parallel to building out the CI hardware platform we’ve been working on the design for a low cost medium power amplifier for LTE Band 3. While suitable low power RF amplifiers are available at a modest…

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…
