Open Source Hardware (and Gateware) for 5G

Open Source Hardware (and Gateware) for 5G

OSHWA recently sent a response to the 5G Challenge Notice of Inquiry published by the National Telecommunications and Information Administration (NTIA) in the US. The Notice of Inquiry focuses on the development of an open-source software stack for 5G wireless communication. In our response we highlighted the role that Field-Programmable Gate Arrays (FPGAs) can play in the path from the radio receiver to the 5G software stack and conversely from the software stack to the radio transmitter. FPGAs can cope with very high data rates, for which pure software solutions can be suboptimal.

It is therefore important that FPGA designs are made part of the challenge, and also that these designs be open-source for the same reasons that it makes sense to open-source the software stack. FPGA design is typically done using Hardware Description Languages (HDLs). HDL code is fed to synthesis, place & route and bitstream generation tools. The bitstream file then configures the FPGA, so its logic gates and flip-flops implement the circuit specified in the design. HDL code is sometimes called “gateware” (a reference to the logic gates it targets) to distinguish it from software.

If researchers and developers are going to collaborate on common open-source gateware and software, they would ideally do so using an open hardware platform. This would democratize access, enlarging the talent pool which can contribute to the effort. It would also protect the development against vendor lock-in and save time and effort on porting to different imperfectly-compatible platforms.

Finally, this could be an opportunity to improve the Free and Open Source Software tools for gateware design. There are thriving communities of open-source software-defined radio and FPGA tool developers, and we believe including them in this challenge and having hardware and gateware in the picture will result in a better 5G for everyone.
