OpenRadio: a programmable wireless dataplane

Manu Bansal, Jeffrey Mehlman, Sachin Katti and Philip Levis

Open Radio is a design for a programmable wireless dataplane. Wireless protocols evolve quickly and infrastructure for wireless must support this. Protocol changes are continuous but many basestations deployed. OpenRadio exposes an interface to program PHY and MAC layers. Key contributions

  1. Decouple protocol definition from hardware

  2. Abstraction layer for protocols decoupling processing and decision

Design goals

  • 20MHz processing for OFDM complexity protocols

  • 25 mu sec response time for ACKs.

Multicore architectures for DSP will be used to get speed necessary.
