5G is the current major challenge for researchers working on the future of wireless systems. We’ve written many articles on the subject, such as the recently announced NTT Docomos’s trial experiments, the required business model innovations, and European movements, with 5G-Infrastructure-PPP as a prominent example. There’s a lot more useful information in our blog, including a massive MIMO tutorial that tackles the subject from theoretical angle. We’ve also put a lot of attention to describing the technical challenges facing massive MIMO.

In this post, I’d like to map out the potential key technology enablers considered for 5G and where Nutaq can assist you.

Technology Solution Value

30 to 90 GHz roadmap, with above 100 MHz bandwidth


Unique baseband units capable of handling such large amounts of data in real-time

Cognitive radio PicoSDR  Radios that can reconfigure themselves in real time (software-defined radios, or SDR). 

Radios that are aware of their wireless environment and can respond to it intelligently (cognitive radios).


Used in one of the largest open cognitive radio lab on the planet: CorteXlab

New modulation schemes and new waveforms PicoSDR  Mixed PC/FPGA architecture for implementing the most demanding and real-time part of your algorithms in the FPGA-PHY layer 

Enables PC (GNU Radio or C code) handle the less demanding operations MAC layer and above.

Device-to-Device communication ZeptoSDR  Built for low-power, portable, advanced wireless protocols on production-ready components 

High quality radio provides the performance needed for 3GPP prototyping

No VHDL coding skills required to use FPGAs

Having powerful hardware is not enough. Nutaq’s focus is to make the FPGAs easy to use, regardless of whether you have VHDL coding skills or not. Figure 1 shows our software offering based on the PicoSDR example, but the general idea remains. The Board Support Development Kit (BSDK) is used when you program the FPGA in VHDL with Xilinx ISE/Platform Studio (XPS). The Model-Based Design Kit (MBDK) is when you program the FPGA from a Simulink flow graph with the Xilinx System Generator tools.

All of these solutions are designed to accelerate your 5G research. They let you focus on the most important of your work: algorithm exploration and innovation. Stop wasting your time putting together different pieces of vendor equipment, drivers, IP cores, etc. Above all, Nutaq understands the value behind researcher-friendly tools for rapid prototyping, even without the necessity of writing HDL code.
