This directory contains the openLTE source code. For support, please
subscribe to openlte-discuss@lists.sourceforge.net. Details can be
found at sourceforge.net/projects/openlte/.
The directory structure for the project is:
octave Octave test code
cmn_hdr Common header files
liblte C++ library of commonly used LTE functions
cmake Files needed for cmake
LTE_fdd_dl_file_scan A gnu-radio LTE FDD DL file scanner application
LTE_fdd_dl_file_gen A gnu-radio LTE FDD DL file generator application
LTE_fdd_dl_scan A gnu-radio LTE FDD DL scanner application that
currently supports rtl-sdr, hackrf, USRP B2X0,
and bladeRF hardware
LTE_file_recorder A gnu-radio LTE file recording application that
currently supports rtl-sdr, hackrf, USRP B2X0,
and bladeRF hardware
LTE_fdd_enodeb An LTE FDD eNodeB application that currently
supports URSP B2X0 hardware
openLTE is dependant on the following:
1) GNU Radio
2) GrOsmoSDR
3) rtl-sdr
4) UHD
5) HackRF
6) bladeRF
7) polarssl
8) iptables
To build the C++ and python code use the following:
$ mkdir build
$ cd build
$ cmake ../
$ make
To install the C++ and python code use the following:
$ mkdir build
$ cd build
$ cmake ../
$ make
$ sudo make install
All testing was performed against the following configuration:
- Intel Core i5-2557M
- Ubuntu 12.04
- GNU Radio 3.7.2
- GrOsmoSDR 0.1.1
- rtl-sdr 0.5
- UHD 3.6.0-1
- HackRF 0.2
- bladeRF 0.9.0

# FILE SCANNER #
##################
To use the installed C++ and python code for the file scanner,
set the PYTHONPATH env variable to
/dist-packages/gnuradio/
for instance /usr/local/lib/python2.7/dist-packages/gnuradio/
and make sure that /usr/local/lib is added to /etc/ld.so.conf
and that LD_LIBRARY_PATH is set to /usr/local/lib (export
LD_LIBRARY_PATH=/usr/local/lib). Then run LTE_fdd_dl_file_scan.py
and specify a recorded LTE file as the input. For example:
$ LTE_fdd_dl_file_scan.py lte_file.bin
To see a list of options, use the -h option:
$ LTE_fdd_dl_file_scan.py -h
To change the input file data type (int8 or gr_complex), use the
-d/--data-type option:
$ LTE_fdd_dl_file_scan.py -d int8 lte_file.bin
For int8 data type, the recorded LTE file must be interleaved signed
8-bit I and Q samples. For the gr_complex data type, the recorded
LTE file must be sequential gr_complex I/Q samples. Files recorded
with LTE_file_recorder or generated with LTE_fdd_dl_file_gen can be
scanned with this application.
####################
# FILE GENERATOR #
####################
To use the installed C++ and python code for the file generator,
set the PYTHONPATH env variable to
/dist-packages/gnuradio/
for instance /usr/local/lib/python2.7/dist-packages/gnuradio/
and that LD_LIBRARY_PATH is set to /usr/local/lib (export
LD_LIBRARY_PATH=/usr/local/lib). Then run LTE_fdd_dl_file_gen.py
and specify an output file for the LTE fdd downlink signal.
For example:
$ LTE_fdd_dl_file_gen.py lte_file.bin
To see a list of options, use the -h option:
$ LTE_fdd_dl_file_gen.py -h
To change the output file data type (int8 or gr_complex), use the
-d/--data-type option:
$ LTE_fdd_dl_file_gen.py -d gr_complex lte_file.bin
For int8 data type, the generated LTE file contains interleaved
signed 8-bit I and Q samples. For the gr_complex data type, the
generated LTE file contains sequential gr_complex I/Q samples.
Files generated with this application can be scanned with
LTE_fdd_dl_file_scan.

# SCANNER #
#############
To use the installed C++ live scanner, make sure LD_LIBRARY_PATH
is set to /usr/local/lib (export LD_LIBRARY_PATH=/usr/local/lib),
plug in rtl-sdr, hackrf, USRP B2X0, or bladeRF hardware, run
LTE_fdd_dl_scan, and connect (via telnet, nc, etc) to the control
port at port number 20000. Scan parameters can be changed and
scan results can be observed on the control port. For a list of
parameters simply type help on the control port.
###################
# FILE RECORDER #
###################
To use the installed C++ file recorder, make sure LD_LIBRARY_PATH
is set to /usr/local/lib (export LD_LIBRARY_PATH=/usr/local/lib),
plug in rtl-sdr, hackrf, USRP B2X0, or bladeRF hardware, run
LTE_file_recorder, and connect (via telnet, nc, etc) to the
control port at port number 25000. Recording parameters can be
changed on the control port. For a list of parameters simply type
help on the control port. Files recorded using hackRF, USRP B2X0,
or bladeRF hardware are recorded using a sample rate of 15.36MHz.
Files recorded with all other hardware are recorded using a sample
rate of 1.92MHz. All files recorded with this application can be
scanned with LTE_fdd_dl_file_scan.
############
# ENODEB #
############
To use the installed C++ eNodeB, make sure LD_LIBRARY_PATH is set
to /usr/local/lib (export LD_LIBRARY_PATH=/usr/local/lib), plug in
USRP B2X0 hardware, run LTE_fdd_enodeb, and connect (via telnet, nc,
etc) to the control port at port number 30000. eNodeB parameters
can be changed on the control port. For a list of parameters simply
type help on the control port. A MAC and above level PCAP trace is
output to /tmp/LTE_fdd_enodeb.pcap. Data packets are routed through
a tun device named tun_openlte. Wireshark can be used to observe
IP packets on tun_openlte to inspect the IP traffic to/from UEs. In
order to configure properly, set the ip_addr_start parameter to the
begining of a non-conflicting private address range (i.e. 10.0.0.1)
and set the dns_addr parameter to the primary DNS address listed by
your modem. All UEs will be assigned IP addresses in the range
of ip_addr_start to ip_addr_start+254 and all traffic will be tunneled
through the tun device to the internet using NAT/iptables.
NOTES: This application has been tested exclusively at 5MHz
bandwidth. Higher bandwidths are supported and performance may
vary based on processing hardware.
WARNINGS: By using this application you risk disruption of service in
a public network, even if you are not directly interfering with the
radio transmissions. This is a criminal act in most countries, and a
much more serious offense than a simple violation of radio spectrum
regulaions. It is highly recommended to use this application only
with antennas and test UEs inside an RF Shielded Enclosure (Faraday
Cage).
############
# OCTAVE #
############
To use the octave code, run the top level octave .m files:
lte_fdd_dl_transmit.m and lte_fdd_dl_receive.m. If multiple
transmit antennas are used, the outputs need to be combined
before input to the receiver.
