[Discuss-gnuradio] European Workshop on Testbed-Based Wireless Research - Call for Contributions
European Workshop on Testbed-Based Wireless Research November 19th 2014 KTH Main Campus, Stockholm, Sweden web: http://people.kth.se/~perz/ewtbwr/2014/ws.html Following up on the successful "scandinavian workshop on testbed based wireless research" of last year we are happy to announce the more ambitious first "European workshop on testbed based wireless research" which will also be held at the Royal Institute of Technology, KTH. ### Workshop scope ### Over the last decade software-defined radios have become an important tool for evaluating novel ideas on algorithms and protocols for wireless communications and networking. This has been recognized by many research groups in academia and industry, leading to a steady proliferation of wireless testbed equipment around the world. This is accompanied by a massive increase in research output related to experimental evaluation rather than traditional methods like mathematical analysis or simulations. In this workshop, we intend to offer the community a meeting venue for knowledge exchange in a rather informal way. The workshop is dedicated to 1. The presentation of novel research results at an early stage without formal paper submission, reviewing and a subsequent workshop proceeding. This gives researchers the opportunity to get feedback on their work at an early stage, likely improving subsequent publications. 2. Sharing prototyping best-practice and development experience with other researchers and developers in the community, and discussing initiatives and concerns with respect to different development platforms together with representatives of the platform development teams. To achieve this, the workshop is composed of three different parts: - Presentation slots for (early) research results, accompanied by an abstract but no formal paper published later in a proceeding. - Poster and demo presentations also accompanied by an abstract but no paper presented in a proceeding. - Parallel two-hour community meetings, with Mango and National Instruments respectively. The two communities will present the latest new from their respective development platforms USRP (National instruments) and WARP (Mango). These community meetings will also have the opportunity for researchers to discuss their concerns, needs, ideas, suggestions etc. with the company representatives and the broader community. For paper, poster or demo presentation, we solicit contributions in the broad areas of wireless communications and networking as long as they are related to experimental work. Areas of interest are (but not limited to): - Physical layer design - Protocol design, not only limited to the medium access control layer - Network optimization and management - Validation results, i.e. performance comparisons between theoretical and experimental work - Tools for experimental platforms (i.e. new libraries, novel hardware/software designs etc.) ### Registration ### For participants the workshop is free of charge, i.e. we do not request a registration fee. However, participants need to register: - Pure participation requires a registration by November 1st. - Talks need to be registered with a title and an abstract by October 15th. The organizing committee will decide on the assignment of presentation slots if we receive too many registrations for talks. The slot assignments will be based on relevance to the workshop community and novelty of the contribution. - Demos are accepted as they are proposed, as well as poster presentations. Here, we request a registration by November 1st. Abstracts for talks and demos should be limited to two pages in IEEE conference style format. Please register talks, demos and/or participation by sending an email to per.zetterb...@ee.kth.se with subject [EWT] . ### Workshop Organization and Program Committee ### - Per Zetterberg (KTH Royal Institute of Technology) - James Gross (KTH Royal Institute of Technology) - Patrick Murphy (Mango Communications) - Leif Johansson (National Instruments) - Linda Doyle (Trinity College Dublin) ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio

Specifically, follow the instructions for running "./pybombs env" and then
sourcing the resulting file. I looks like you just don't have the library
and binary paths set up properly.

Taking Martin and Marcus' responses here, I've added a bit to the
QuickStart guide to briefly explain the options a bit more. See the bottom

It's telling you that you haven't properly connected all of the ports for the block. Take a look at your QA code and make sure that the flowgraph is set up correctly.

[Discuss-gnuradio] Paging all students: Short survey
Dear list, I sent this request for participation out a while back. I'm currently working on a presentation for GRCon, and I can still use some feedback on this survey. Thanks! == Original request: == Hey everyone, and all students that have used (or are using) GNU Radio for some purpose. I'm currently working on a presentation on GNU Radio in academic teaching. To get a better understanding of how GNU Radio is used by students in particular, I'd appreciate it a lot if I could get some feedback from you guys. I have compiled a short survey (literally takes less than 3 minutes to complete) asking some questions about your usage of GNU Radio. So please, if you're a student, or you know students, please give this a quick clicking, or forward it people who are studying: https://docs.google.com/spreadsheet/viewform?usp=drive_web&formkey=dHBjbGY0VmhCWGFGcl9ra1MyTEFKY1E6MA#gid=0 The results will be presented at GRCon 2014 in DC this year. Again, thanks! Martin ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
