Jane -
We (Harvind and I) have no foreseeable plans to use OpenBTS with the
USRP2. There are several reasons we will stick with the USRP1, but
if I detail them on this list I'll risk getting cited for contempt of
court. Really. http://openbts.sourceforge.net/order.pdf
But OpenBTS is open source, after all, so if more and more people
want to hack OpenBTS to work with the USRP2 they are welcome to do so.
"Do not use a transmit antenna" means "Do not use a transmit
antenna". I don't know how to state that more clearly. The reason
is that if you DO use a transmit antenna you will probably be
violating your local radio spectrum regulations, whatever those might
be, and you risk disrupting cellular telephone service for your
immediate neighbors. This would be BAD and I do not sanction it. So
unless you REALLY know what you are doing, you should not use a
transmit antenna. Plenty of power leaks out of the USRP for benchtop
testing and development.
You will need a receive antenna, though. That's an entirely
different matter.
"RFX-style" means "of the same general style as the RFX900 or
RFX1800". These two boards are nearly identical, so I lumped them
together in the group "RFX-style".

Hi all,
Is anyone working on OpenBTS with USRP2? On the website, http://
www.gnuradio.org/trac/wiki/OpenBTS/DesktopTestingKit, OpenBTS has
not been used with URSP2. However, USRP2 is new and fast. I think
more and more people are going to use USRP2 to develp their SDR.
Should I buy a USRP1 or a USRP2 to run OpenBTS?
http://www.gnuradio.org/trac/wiki/OpenBTS/DesktopTestingKit shows
that "Do not use a transmit antenna."
What does it mean "Do not use a transmit antenna"? Does it mean
that I don't need to connect a antenna to a daughter board?
http://gnuradio.utah.edu/trac/ticket/334 shows " one RFX-stype
receive section ". Does it mean that "one RFX-style"? A typo?
Thank you,
Jane
