I now have a tested setup that works, for me, which I would like to share with others. Apologies for sharing on the 'issues' list, but this is where most people will look for solutions. Admins, feel free to close - unless others repeat this sequence and have issues, I will be happy to assist resolving. I am running Ubuntu The setup described below follows from a fresh installation of the OS, as I wanted a reproducible setup from a clean install.

Having worked on this for days, I have got the time for the sequence of "erase old OS, install new OS, build system, get srsLTE running" down to a 25 minute 48 seconds process.

I'm sure this time could be improved :. Install Ubuntu Wait for the OS to advise of updates; install these and reboot. If not, try another USB port. That completes the installation. Before running the code, I edited the enb config file to get the transmission on a frequency band20 that is used by my phone in Europe. In the output of the above you should see the SDR is detected.

From this point, I have confirmed on a spectrum analyser that the enb is transmitting. I have yet to confirm cell information detection by an actual mobile phone, but those are next steps, followed by full connectivity with a test SIM.

Thanks Mike for the detailed report. Such a manual would actually nicely fit into the official user documentation which is hosted here. Feel free to submit a PR if you wish. Regarding the config I have one comment. Other may correct me please. Thanks Andre, I'd be happy to once I get confirmation that others have had the same result. I will test your suggestion out to see if it helps. I presume that setting you mention configures what matching circuit the RX SMA connector is routed through.

I haven't got as far as testing a mobile phone yet, but will test your comment.If you're Sam Machin, Andrew Back, and colleagues, you get 16 rapidly-deployable GSM base stations for use at Electromagnetic Fielda three-day event held in the middle of a field every two years. Having provided the general-purpose processing technology at the heart of the LimeNET CrowdCell, Gigabyte is now going to market with a fully-supported ready-to-deploy implementation of the ultra-low-cost software-defined small-cell system powered by Lime Micro's LMSM field-programmable radio-frequency IC technology.

We need the edge cloud. Describes the combination of Lime Microsystems' LimeSDR Mini and a Raspberry Pi single-board computer as "excellent for this type of research," proving that software defined radar projects "can be built at an affordable price at an amateur level without expensive radios and convoluted analogue gear.

Low-cost free and open source design, based on the LMSM and the Raspberry Pi Compute Module 3, combines powerful software defined radio SDR capabilities with general purpose processing GPP for everything from cellular network deployment to amateur radio projects. Lime Microsystems named as a provider of end-to-end technology for the CrowdCell Project effort to produce an open source cellular relay platform using general purpose processors GPP and software defined radio SDR technologies.

Okay, thanks.FL to SMA cables can be connected. Not all of these ports need to be used simultaneously, and your first step is to decide which of the ports you need to connect for your particular use case - along with, optionally, choosing a case compatible with the number of ports you are going to use.

The use of a Y-splitter, which uses one Type A plug for power and data and a second Type A plug for additional power, is recommended; users of portable devices like the Apple MacBook Air or Microsoft Surface families, which have USB ports on opposite sides of the device, may also require a USB extension cable which should be connected to the secondary, power-only, leg of the Y-splitter.

Lime Suite provides an SDR driver and a configuration interface along with numerous utilities. Support is provided for the following platforms:. Lime Suite can be installed by compiling from source or via binary packages. Note that in the case of Windows a hardware driver must also be installed as a separate part of the process.

For further details see the Lime Suite documentation. This firmware is constantly updated to improve the LimeSDR's functionality and reliability, and running the latest version is recommended. To update the LimeSDR's firmware, as well as to test the communication between the host PC and the LimeSDR, open your operating system's command-line interface and run the following command:. This will update both the firmware and the gateware on the LimeSDR to the version supplied with your copy of Lime Suite.

Do not disconnect the LimeSDR during the update process. This loopback test is the simplest and most direct way of confirming that you have a functioning board with appropriate USB controller firmware and FPGA gateware loaded. Jump to: navigationsearch.

It is designed for maximum modularity and code reuse with minimal inter-module or external dependencies. This distribution is based on Ubuntu Linux. Website of Elsewhere in the world of open-source cellular communications, srsLTE has been upgraded to version We show the potential of the srsLTE library by extending the baseline code to allow LTE transmissions in the unlicensed bands and coexistence with WiFi.

This software enables running a full end-to-end, open-source LTE system. The numbers shown above are from our Coverity Scan Report, which analyzed million lines of open source code. Unlike the IMSI, a mobile device never transmits its own phone number to the network side in the radio. Classes are not included. Phone number is a unique identity code of a mobile subscriber, which plays a more important role in the mobile social network life than another identification number IMSI.

This is messy, sorry You should be sure you're aware of the implications of using Band 7. While the latest version of srsLTE works on my laptop without any issues, they do not work on the RPi4 based on my testing. That's version After trying a bunch of things see the list belowI ended up moving back to the latest version, It works on my laptop and that release added important features and various bug fixes missing from I had hoped it would fix the underlying issue and I'd prefer to be working closer to the most recent release.

Here are the versions I'm using currently. They work on my laptop but do not work on the RPi4. If you're trying to get this working, I suggest attempting to use the versions listed in Ralph's message instead; maybe you'll have better luck than I. Start over a third time with a blank SD card, be sure I compile all the versions Ralph suggested, and see how that goes. Ralph's original work was done at 3MHz. Because my test devices do not seem to like connecting to a 3MHz 15 resource blocks network on Band 7 and I figured that wasn't worth testing.

I tried falling back to I need to go back and document them. After adjusting things to get clean signal, I still hit the same issue I've been hitting all along. The RAR isn't transmitted in time.

I tried running all the tests to ensure they were passing and found one that does not pass on I looked into this and it looks to be an issue with the test more than a root cause for my issue.

SoapySDR gives these ports slightly different name. You need to be able to write your own SIM cards.


I had to ask the seller for the software after purchase. They sent me to some Bidu site to download two archives. The software in both archives required Windows. I ended up spending way too much time getting the CardTool software working. It required VB6 components and wasn't clear enough about what settings to use to actually flash the cards I had.

I did realize that the ACS website provides a pretty reasonable driver installer package for the thing though, so that worked out well. Without this process, it was touchy. The SIM values popped up on screen and I was able to start going through and editing the values manually. Note: The information here is a little bit inaccurate. The best place to look up the meaning of these values is in the 3gpp spec.Running as an application on a standard Linux-based operating system, srsUE connects to any LTE network and provides a standard network interface with high-speed mobile connectivity.

This User Guide provides all the information needed to get up and running with the srsUE application, to become familiar with all of the key features and to achieve optimal performance. Transmission modes 1 single antenna2 transmit diversity3 CCD and 4 closed-loop spatial multiplexing. It is responsible for link adaptation, power control, cell search and cell measurement.

The MAC is responsible for control and scheduling information exchange with the eNodeB, retransmission and error correction HARQ and priority handling between logical channels.

The RLC manages multiple logical channels or bearers, each of which operates in one of these three modes. Transparent Mode bearers simply pass data through the RLC. Unacknowledged Mode bearers perform concatenation, segmentation and reassembly of data units, reordering and duplication detection.

Acknowledged Mode bearers additionally perform retransmission of missing data units and resegmentation. It uses System Information broadcast by the network to configure the lower layers of the UE and handles the establishment, maintenance and release of the RRC connection with the eNodeB. The RRC manages cell search to support cell selection as well as cell measurement reporting and mobility control for handover between neighbouring cells.

The RRC is also responsible for handling and responding to paging messages from the network. Finally, the RRC manages security functions for key management and the establishment, configuration, maintenance and release of radio bearers.
