An open source, crowd funded platform

In January 2013, Nuand announced its bladeRF open-source software defined radio on the crowd funding website KickStarter. In order to take the project to market it needed $100,000. The Nuand platform, which combines USB 3.0 connectivity with a field programmable RF (FPRF) transceiver, raised double this figure within just one month and over 500 backers pitched an average of $380 each. At the heart of this success is the boards flexibility and openness, enabling [...]

The first professional-grade open source base station

In 2013 Fairwaves announced the UmTRX, the industry's first truly open-source and professional grade base station transceiver. This is an incredibly important launch as it fills in the last remaining gap in the open-source GSM ecosystem so means anyone can now build a complete base station from open-source pieces. The UmTRX launch advances the open-source model beyond the current USRP systems, where typically schematics, but not layout files were published. [...]

Enabling multimode MIMO

The ability to run MIMO (multi in, multi out) is an essential part of today's cutting edge wireless standards, including IEEE 802.11n (Wi-Fi), 4G, 3GPP Long Term Evolution (LTE), WiMAX and HSPA+. Using multiple antennas at both the transmitter and the receiver significantly improves communication performance and MIMO has attracted significant attention in the wireless comms sector as it significantly increases both throughput and link range without additional bandwidth or transmit power. [...]

Implementing M2M communications to better manage logistics

The machine to machine (M2M) technology sector is growing quickly and the need for reliable communications has proven to be vital. Some of the biggest growth areas are agriculture and logistics. In agriculture, information is needed from many sensors on times to feed, water, spray or harvest a crop. Indeed, M2M technology is even making it possible to detect when an animal has injured itself (gait analysis) or has been [...]

Combining FPRF and FPGA to create the future of radio

In 2013 the EU, in collaboration with the Seventh Framework Programme set out the technology roadmap for radio optimisation. Called Acropolis (Advanced coexistence technologies for radio optimisation in licensed and unlicensed spectrum), the roadmap seeks to establish the key technologies for future software defined and cognitive radio systems. Lime's field programmable RF transceiver (FPRF) was named in the report for its ability to manage multiple bands and multiple standards and its ability [...]

Adding RF functionality to Arduino

Myriad RF is an open source, non profit initiative created by Lime to increase access to RF development hardware. The low cost boards, and free, editable design files can be used for virtually any wireless application. In December 2012, whilst the project was in its alpha development phase, Lime created a system to link it to the well renowned open source hardware project, Arduino. Arduino is one of the most well used [...]

Communications in a disaster zone

According to a 2005 New York University report,one of the key preventable losses of life comes from the failure of telecommunications infrastructure. The authors of the report claim this failure causes “delays and errors in emergency response and disaster relief efforts” and state “the risk associated with communications failures remains serious because of growing dependence upon these tools in emergency operations”. Significant recent events include the Tohoku earthquake and tsunami [...]

Software upgradable comms devices that work in all countries

The first commercial LTE network was launched in Scandinavia in 2009 and the technology is now being deployed across all continents and most major countries have either launched, or plan to launch their first network. But if you look more closely, the rollouts are still in their infancy with few networks up and running in each country. Due to the unique wideband nature of LTE, throughput decline often occurs at macrocell edges, [...]

Speeding wireless system test and optimisation

The test and evaluation phase of wireless system development is typically a rate limiting step in the design process. It is also a significantly expensive one. In December 2011 Agilent Technologies pioneered a new method of for the testing and evaluation of advanced wireless systems based on the Lime LMS6002D field programmable transceiver IC. This method has cut both the development time and number of optimisation cycles required, significantly speeding [...]
