• Hello, I think that Erkki's proposal is good and covers the main topics. I would like to add a couple of bullets to the RF challenge related to architetural trends:
• - generic multi-standard RF architectures - multi-band, multi-standard RF technologies and interfaces from antenna to ASIC - impact of flexible spectrum use and cognitive radio paradigms to future wireless systems All of the topics have major architectural impacts and are actively discussed at least in the research communities. I see that each of these will face both a technology and legacy challenge need carefull considerations. Regards, Aarno
• P.S. Unfortunatelly I can not join the planning meeting tomorrow but here is my feedback for your discussions.
• April 11, 2008, Erkki Kuisma: Hi, Let's continue planning of the workshop. I see three different issues, which need to be discussed.
  • Wirtual IP based or SDR based platform evolution - pros and cons of each - timing and evolution from current approaches, ie. legacy issues
  • SW development environment and culture needed in each approach - multicore and vector processor based platforms need in any case new approach - what are the solutions in each case
  • RF challenge - RF is challenging in any approach - are there differencies in RF interface evolution between the approaches - technologies needed to support each approach The outcome should be a list of opportunities and recommendation about how to speed up technology development.
  With our current architecture options we are now not leading the game in all areas (cost, size, performance, power, flexibility, time to market etc.) Please give your comments and forward this to any fellows you think could help in building the agenda. Br Erkki
• April 8, 2008, Gopal Raghavan: Hi, In the previous meeting, we spoke about the role of system design and virtual platforms in Nokia. There is SDR view and on the other hand there is parameterized IP components modeling using high level languages (like bluespec). As Mikko, suggested I will start discussion on this topic with Erkki and few others to outline the workstream for fellows meeting.
• Mar 25, 2008, Mikko Terho: I had an idea tht this parmietrized radio or some new system arhitecure should be one of the workstreams for the up coming Nokia Fellows meeting and I had asked Raghvan to be active on this. Could you Kima and Erkki take the ball and prepare this for one of the "Fellows Workstram" or group work. I think Mike Jeger could also be a good member in the team. Barbara is in charge of the program to our meeting in Lausanne. Mikk0 Terh0
• Mar 25, 2008, Kim Kaltiokallio: Hi, The real challenge in the software radio is in the RF front end. Today we have many different bands and band combinations in the products. Most of the RF complexity is in the RF front end components. It would be great if there would be a radio receiver and transmitter that could handle large band widths and we could have only three or in maximum four of these front ends. Even better if you could design high Q (low loss) narrow programmable filter to the RF front end. We can discuss this over a teleconference. Best Regards, Kim
• Mar 24, 2006, Gopal Raghavan:
• Hi Kim, Mikko and I had a discussion sometime back about building parameterized radio components that operates in sets of 500Mhz bands. He asked me to discuss this further with you. If you have any further thoughts/ideas in this direction, please let me know. We can also try to discuss this over a telecon. Br, Gopal
