LimeSDR: Flexible, Next-generation, Open Source Software Defined Radio coming soon to Crowd Supply. Sign up to receive updates and be notified when this project launches.

LimeSDR is a low-cost software defined radio through which apps can be programmed to support any type of wireless standard, e.g. UMTS, LTE, LoRa, Bluetooth, Zigbee, RFID, Digital Broadcasting, etc.

Applications:

There are no limitations to the functionality of the LimeSDR it contains enough processing power to function in any number of ways according to the software that is run on it. Unlike equivalent products the LimeSDR board isn’t manufactured for a single purpose. For example it can be implemented as a

Basestation

• Practical solution for access to areas currently without coverage
• Provide mainstream infrastructure solution for next generation of networks for operators giving them the option to differentiate their offering by utilizing a wealth of software apps that’s only limited by one’s own imagination.

Gateway for IOT/wifi router

• Enables wireless networks to be programmed accelerating IOT and allowing anything to communicate with anything.

The platform is based on Lime’s latest generation of Field programmable RF transceiver technology, combined with FPGA and microcontroller chipsets. These connect to a computer via USB3. LimeSDR then delivers the wireless data and the CPU provides the computing power required to process the incoming signals, and to generate the data to be transmitted by LimeSDR to all other devices.
