The crowdfunding campaign for the open-hardware LimeSDR XTRX, an updated and fully-supported successor to the Fairwaves XTRX, is now open, with hardware expected to ship to backers at the end of November. Designed as a drop-in replacement for the discontinued Fairwaves XTRX, the LimeSDR XTRX puts a Lime Microsystems LMS7002M…

Wavelet Lab has officially opened crowdfunding for its compact uSDR M.2-format software defined radio board and browser-based control platform, with a little under a month left to reach its funding goal for production. Based on the Lime Micro LMS6002D field-programmable radio frequency chip and an AMD Xilinx Artix-7 field-programmable gate…

Wavelet Lab is looking to make software-defined radio more accessible, using a compact M.2 SDR module dubbed the uSDR alongside a WebUSB-connected browser-based software bundle with some impressive collaboration features. “uSDR is an embedded software-defined radio board that targets ease of use and collaboration,” Boston-based Wavelet Lab says of its…

Gabe Emerson, of YouTube channel “saveitforparts,” has built a low-cost augmented reality system which lets you peer into the skies and see satellites as they pass – acting as a microwave-frequency camera. “I’ve dabbled in radiotelescopes before, mostly as a way to use old TV satellite dishes,” Gabe explains. “However,…

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…
