SANTA CLARA, Calif., Nov. 29, 2016 /PRNewswire/ -- Based on its recent analysis of the software-defined radio (SDR) market, Frost & Sullivan recognizes Lime Microsystems with the 2016 Global Technology Innovation Award. Acknowledging the rising importance of programmable radio frequency (RF) in an increasingly software-driven world, Lime Microsystems introduced the LimeSDR, a high-performing SDR that addresses carrier-class requirements.
The LimeSDR stands out from the crowd for its full duplex RF chain. Early adopters have applauded the consistency of its transceiver across an exceptionally wide bandwidth of 100 kilohertz (KHz) to 3.8 gigahertz (GHz). The company achieves this by combining its LMS7002M transceiver chip with Altera's Cyclone IV Field Programmable Gate Array (FPGA) for some of the physical layer processing. Altera has been an investor in Lime Microsystems and strategic partner since 2014 and has contributed to the LimeSDR crowd-funding campaign. LimeSDR's reference board supports 2G, code division multiple access (CDMA), high speed packet access (HSPA), and long-term evolution (LTE) in all regional bands as well as Wi-Fi, LoRa, ZigBee, and Bluetooth. LimeSDR is programmed through a USB 3.0 IP connection, and the host drive architecture includes the Lime Suite (a software for interoperability with other applications) and SoapySDR (an abstraction layer for interoperability with alternative SDR hardware). Competing reference boards match some of LimeSDR's specifications; however, none offer the combination of frequency range and open source hardware design and software. In fact, other SDR brands sometimes use Lime Microsystems' transceiver chips. "LimeSDR's value proposition also gets a boost from app-store functionality. For instance, Canonical's Snappy Ubuntu Core, a lightweight Linux distribution, allows developers to download technology stacks and package their own protocols," said Frost & Sullivan Research Director, Adrian Drozd. "The LimeSDR offers developers unprecedented levels of flexibility, quality, openness, and affordability in radio access networks." Lime Microsystems' business model for SDR relies on the rapid adoption of its products. At this early stage, the company is focused on driving developer activity by making products available at compelling prices. Another initiative to drive scale is its certification program, which includes 10 LimeSDRs with cases, antennae, and software as well as a day of training for up to 10 people at Lime Microsystems' head office in Guildford, United Kingdom. "Lime Microsystems recognizes the importance of developers experimenting with SDR at a time when many Internet of Things initiatives and platform owners are competing for their attention," noted Drozd. "Even though its traditional business is customisable, the company has championed the open source movement."
