</span>This is true, but even OpenBSC and related projects are suffering from a<br>
lack of attention. Despite being one of the founders of sysmocom, I<br>

</span>Honestly, I'm not sure. The big difference is that there are commercial<br>
users of OpenBSC, OsmoBTS, etc., and they can afford to fund some of the<br>
work on those projects. For OsmocomBB I don't think there's much of a<br>
chacne for commercial interest. You can buy an entire phone for USD 10<br>
these days, including a license for the protocol stack / software - so<br>
why bother investing in a "new" implementation of GSM.<br>
<br>
There are some exceptions like test devices or virtual phones for load<br>
generation, but those are also not interesting to most people anymore in<br>
2016.<br>
<br>
OsmocomBB doesn't support GPRS, EDGE, UMTS, HSPA and likely never will,<br>
unless a maniac comes around who invests several months of full-time +<br>
spare-time work into what most people would considre a hopeless cause.<br>
<br>
For LTE, there's luckily the excellent free software srsUE<br>
implemntation. However, it requires a Core-i5, unless somebody manages<br>
to transplant the protocol stack onto one of the commercially found LTE<br>
baseband / PHY implementations actually used in phones.<br>
<br>
Getting back further to your question: Even on the supported hardware<br>
(Calypso based phones), there are still many bugs and features missing,<br>
and nobody contributes. It makes me quite sad, as Andreas and I have<br>
put in a lot of energy to get the project going, but then nobody really<br>
got int carrying it along further.<br>

<br>
</span>We all are, but mostly the work gets done when we are not looking but<br>
actually writing code :P No offence, I just couldn't resist...<br>
<br>
All the best, I'd definitely love to see progress on the "SDR based PHY<br>
for OsmocomBB" front.<br>
