2. Purpose of this Workshop We have a compelling new research platform – Enables research that has been difficult in the past – Already generating excitements in the community We are making it available to academics – Sora Academic Kit – Sora Academic Program Let’s talk about software radio and wireless research in general – Success stories and pitfalls, new ideas/directions

3. Agenda 9:00-9:30Opening: welcome, agenda, guest introduction Yongguang Zhang (Microsoft Research Asia) 9:30-10:00Introduction to SoraKun Tan (Microsoft Research Asia) 10:00-10:20Tea break and Sora Demo 10:20-10:40Research Short TalkAshu Sabharwal (Rice University) 10:40-11:00Research Short TalkPetri Mähönen (Aachen University) 11:00-11:20Research Short TalkPeter Steenkiste (CMU) 11:20-11:30Research Short TalkHariharan Rahul (MIT) 11:30-12:15Panel: “bridging EE (communications) and CS (networking) with software radio” Moderator: Victor Bahl (Microsoft Research) Panelists: Alhussein Abouzeid (RPI/NSF) Suman Banerjee (University of Wisconsin) Wing Lau (the Chinese University of Hong Kong) 12:15-1:30Lunch and Lunch talk: “Sora Academic Program announcement and Q&A” Miran Lee and Stewart Tansley (Microsoft Research)

4. Guest Introduction 15 from US, 4 from Europe, 35 from Asia Poll 1.Little or no experience in software radio 2.Use software radio on and off 3.Hack software radio upside/down

5. Sora A new way of doing software radio – High-performance (today’s prevailing standards) – Easy to program (high-level programming, tools) – Low cost (e.g., commodity hardware) Turn a multi-core PC running Windows into a high-performance baseband software radio – Hardware interface card (Sora RCB) – High-performance software (Sora SDK)

6. High-Performance Enable software implementation of today’s high-speed wireless systems in standard PC – We implemented WiFi (802.11/a/b/g) and LTE – With core i7 CPU, WiFi in 1 core and LTE in 2 cores – WiFi fully interoperable with commercial device in equivalent performance A truly software radio – Two wireless standards (WiFi and LTE) operating simultaneously over the same RF front-end

7. Programmability Commodity platform, C programming, and a familiar environment  productivity! – WiFi PHY implementation: 4 student-months – LTE UPSCH PHY: 4-5 student-months – Oscilloscope: 2 weeks

8. Software Radio Reality Perceptions – Software Radio is long way from reality – PC’s general-purpose CPU is not fast enough Reality – Today’s fastest PC (4-core) can do fastest wireless – A commodity PC in 2012 may do gigabit wireless We are working on gigabit wireless in a 16-core PC

9. Wireless World Opens Up Currently, a wireless technology takes 10+ years from research to product – Accelerated innovation: Rapid prototyping with software radio Currently, only a few big players can do wireless – Grass-root innovation: Every school, lab can try out new algorithms, new protocols, new systems Metaphor: the Internet revolution

10. Time is Now for Software Radio Software radio is here Exciting time to do research Microsoft Research wants to work with you – To encourage software radio research – New and innovative applications – Building the future together
