First Steps Towards a RISC-V powered LimeNET Base Station

We’re excited to share details of something we’ve been working on in partnership with SiFive, which pairs Lime Microsystems’ field-programmable RF (FPRF) with SiFive’s Freedom U500 platform. The project is to establish the foundations for a radically open wireless base station architecture with unprecedented flexibility.

The combination creates a platform where wireless systems are implemented via software-defined radio, with the ability for custom hardware accelerators to be integrated in FPGA, before progressing to a customised ASIC once their design has been validated.

This fundamental flexibility across both baseband processing and RF will make it possible to bring high-performance radio access network solutions – e.g., for LTE, NB-IoT, and 5G – to market far quicker than ever before and at greatly reduced cost.

The short video below walks through the current lab hardware setup and we’ll be sharing details of our progress in due course.

A high-performance mini PC with an integrated and shielded internal LimeSDR USB micro Type-B, U.FL cables, and antennas. This hardware is fully qualified for compatibility with the LimeNET Ubuntu app store. Save $400 off the post-campaign retail price of $2,599.


LimeNET Gateway

A complete, certified, high-bandwidth cellular gateway that provides Wi-FI and Ethernet Internet connectivity backed by a connection to a 2G, 3G, or 4G macrocell. It provides users with downlink and uplink throughput of 150 and 50 Mbps, respectively, and can connect to any operator network with a SIM card (not included).


LimeNET Base Station

This is a steeply discounted combination of the LimeNET Core + LimeNET Amplifier Chassis. This is all you need to set up your own cellular network!


LimeNET Core

A top-of-the-line gaming PC with an integrated LimeSDR QPCIe board. As the name suggests, it is the core of the LimeNET Base Station, but you can also get it separately for desktop development or integration into your own system.


LimeNET Amplifier Chassis

Amplifier Module for long range connectivity features: Set of two (MIMO): 10 W RF Output Power Amplifier + Duplexer + Antenna Your choice of frequency band (700 MHz, 1.8 GHz, 2.6 GHz, 3.5 GHz) Thick monolithic aluminum body
