Re: cellhunter - openbmap - opencellid revisited... (was Re: CellHunter is moving to a new server)
Hello Risto, note that strengh is already part of the opencellid api. As I've pointed out once, the problem is not all client have access to these data. So do we add all possible fields in the database? Out of the 45 millions of measures, only several millions might have all these data. My suggestion, implemented today in the opencellid api is the following: add the missing informaiton in the extraInfo field, as tag/value. For instance, extraInfo="speed=123,alt=12,hdop=12,vdop=6" etc. This is already used by some tools for instance the cellhunter importer put the team name as "gteam=" value. Then, the algorithm to define the cell might use these extra info. The bad thing is that it would by quite difficult to do query on this extra things. I do not thing that it's the biggest issue. The other problem might be that we need to find a common naming for all possible new fields and ensure validity. For instance, use alt and not altitude, etc One possible option is to add hese as extra possible parameters so it will be checked, but store them as value/pair. Other fields could be added also, to store for instance user agent instead of software version for others type of platforms, or accuracy but not defined in hdop/vdop value but in others type (see JSR179 or Android API). Any opininon on this. -- Thomas LANDSPURG 8Motions Founder/CTO http://www.8motions.com http://www.opencellid.org ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

"ARFCN (Absolute Radio Frequency Channel Number) specifies a pair of physical radio carriers and channels used for transmission and reception on the Um Interface in GSM cellular networks, one for the uplink signal and one for the downlink signal." So it's data to be collected from the cell station rather than something that could be generated/assumed/estimated. Without seeing the cellhunter location algorithm, I don't know how it helps location calculation either... but if the other two DB don't store it, then it can't be that important, right? ;) > > And I don't support the idea of one client uploading to several > databases, the databases should do the syncing.. Well I was having to run the loggers in parallel anyway but it's easier to get one working consistently rather than two... and I prefer the way the OBM logger is designed anyway :) DB sync is where it should be though. I've uploaded different areas to either cellhunter or OBM so it would be good to get them combined efficently. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Do you have any idea what's arfcn - how do you generate it? If you can generate it after the data's collected, couldn't it be created server-side (to me it sound's redundant information if it's generated from other data).

I looked at "common api to submit cells" and found that the openmoko
OBM logger app was missing *one* field (arfcn) that cellhunter api
wanted. Both being opensource, here's my hackish solution to patch the
OBM logger to write that field and a python script to submit records
produced by that patched OBM to cellhunter. You have to run this after
collecting the logs but before you move them to the Processed Logs
folder in OBM. So I do it before I do Upload in the OBM logger app.
YMMV, hopefully the real logger app developers can work something out
between themselves.

If the projects plan to share their data, all projects should gather the same (full!) data of the cells to reach the highest possible precision. Coverage is something you'll be able to reach by everyone focusing on their own projects AND sharing the data. I must say I like opencellID API: it has clear addresses how to put/get cell information or GPS location. THis is something where openbmap is behind. And if OpenCellID has a nice api, it's good, but if I see that it doesn't use speed nor hdop/vdop/alt in calculating the location I trust openbmap more - but it's lacking the proper API. -> work for both of you to do. Focus on it, not in rhetorics & communication issues. Just make your project better than the other one is and share the data.

Hello Risto, That's exactly the objective.There is a clear difference and complementarity between a general purpose database and the "CellsHunter" game for instance. The good news is that we are progressing well with CellsHunter to integrate their database. Currently the integration has been done once but I hope to integrate this much easily soon...

Re: cellhunter - openbmap - opencellid revisited... (was Re: CellHunter is moving to a new server)
Hello Risto, Here is a few facts from such FAQ: Most of the cells from OpenBMap are coming from OpenCellID (the 'untrusted ones') One of the main difference from the three is that only OpenCellID provides a complete access to the data and the measures. OpenCellId added a "CVS uploader" to import bulk CSV data files mainly to be compatible with the OpenBMap logger. I just don't have any OpenMoko phone to test it. I've been out of the mailing list from some time because I am not involved in the OpenMoko community (I am more involved in J2ME and others platforms), but I would be happy to reactivate the integration effort. Since the beginning, OpenCellID was focused on collecting the data and not writing clients for all platforms. I would be happy to support the OpenBMap client and do some modifications if needed. Regarding CellHunter, I would ba happy also to work on an integration. We had some early discussion, but I'll try to reactivate them. Regards, 2009/9/2 Risto H.
