This is awesome! I got back into old GSM phones in 2018 and have been using them on T-Mobile ever since, but of course now they're shutting down their 2G and 3G networks. I've been aware of OpenBTS for a while now and plan on doing my own project with it at some point but still need to do a ton of research first.
Wonderful demonstration. I was hoping to see the GSM Ericsson phones in action, but LG Shine and Nokia 2610 were nice. Did you ever set up a PBX (asterisk) for VoIP calls?
So when will I be able to stop DONATING all my money to Verizon each month and start producing my own cellular data?

Never if you want proper coverage. In the US it‘s legal however to create a somewhat high power 4G/5G cell inside the 5 GHz spectrum, in Europe it‘s limited to 100 MHz at 13dBm. The licenses cost a lot of money, proper network equipment also does, for example a single Ericsson TDD 5G sector antenna costs roughly 50000€ and covers only about 1-3 miles (and you need at least 2 of those).
What is the legality of this? If I did this would I run into problems with the FCC? Also, can you swap sim cards between phones like on a regular GSM network?
It's complicated. It's so low power, you could easily do it unnoticed. If you operate in 900MHz, there is an overlap between the ISM band here in the US, and the GSM frequencies used in Europe that most phones are compatible with. But, it's enough to where random people's phones will try to latch on. So you need to set your parameters for permitted IMSIs very carefully. Yes, you can move SIMs, provided the phones are unlocked and support the frequency (ARFCN) your BTS operates on.
Does openBTS (and this setup) support GPRS or EDGE for packet IP data for internet access, or not? I'm interested in building one of these with the 900Mhz spectrum, as Amateur radio operators in the US are allowed to use some bands that overlap with 900Mhz Extended GSM. That way I would have a better solution to communications on my ranch then I do now.
I run a small boutique hotel. My rooms do not have the infrusture to build phone lines. there are 35 room. can i set this system up. i want to have phones to have the number of the rooms and ofcourse i want to be able to call the rooms from the reception as well as let the rooms call the reception other rooms and the restaurant if they want to make an order. would this system work? do i have to buy mobile phones for each room?
Hi! Question regarding a system like this since I haven't had the opportunity to operate this kind of equipment myself yet. I was curious if this would work with the older 2G NAM phones - number assignment module? I have an old NOKIA that operates using NAM for network connectivity. Other videos I've seen have only ever provided examples using SIM cards, and all research I do online regarding NAM tech comes up shallow or unrelated to my query. In short, my question is - do you know if OpenBTS supports NAM connections, using values like Home SOC, Home SID, etc? Big thanks
This was built using: Ettus Research USRP B100 WBX daughterboard 2 Wilson SMA cellular antennas This was several years ago. But I recall it was about $1,600 total. The USRP B100 is deprecated now.
@@robertjalu6897 This was in 2014, I think. I still have the USRP, it's in my garage. This was a fun project I challenged myself to make work. Learned a ton. I highly recommend it as a project. Since then, 3G UMTS and LTE has been added to capabilities. You just need a USRP that supports the wide bandwidth for LTE.
Nothing about this is cheap. The SDR itself was over $1500 new. The coverage varies based on antenna height and a ton of other factors. As is, maybe half a mile.
This was many years ago. Yes, it was in 900. Yes, OpenBTS has evolved to LTE.

I‘m interested in doing this with a PlutoSDR, will it work in the first place and what other things are required, can I just put a 2nd SIM into my iPhone that has been programmed accordingly and use the PBX system of my fiber router instead of Asterisk? I know this will most likely cause interference in the LTE band 20 uplink if I plan to use the 850 MHz band, is there a way to force the phone to abolish the connection once it requires a too high transmitting power for the cell to be reached? I obviously only want to do this for development purposes on a single 200kHz channel.
Puedo utilizar esta soluciones con Celulares GSM (Android) y poder de igual modo usar los Datos para Navegar por Internet , con una salida publica a Internet.
аывавы ыафываыфва Добрый день! Вы использовали Osmocom NITB? Выход на Sip удалось реализовать? На Хабре была серия статей от Antgorka. Как он собирал сеть сначала GSM, потом GPRS прикрутил к ней. У меня всё хуже. Собственная утилита под WinXP. Простой и убогий симулятор сети. Без SMS и GPRS. Только голос.
The phone is unique in functionality and has no analogues. Our secure phone has its own operating system and unlike smartphones is not vulnerable to any viruses. No one will be able to infect, even the programmers themselves Samsung. There are no third-party installed programs in the phone, all the functionality is built into the firmware of the phone. The phone supports two SIM cards and all functions of control protection work on these SIM cards independently of each other. I. e. you in one phone have two phone with protection. Through our phone it is impossible to infect the SIM card, and if it was infected before it got into the phone then the SIM card will not be able to control the functions of the phone that can harm the user. The phone does not work in a standard way on what the operator of the complex or the operator of communication expects. It's the world's first invisible phone. It is not registered periodically in the network, as the operator wants, it is not possible to determine the location when pinging invisible SMS. The phone can call from remote base stations. The phone can choose one base station and call from it, while he does not see the system BS and they do not see phone. The phone can't remotely turn on the microphone because it shuts off mechanically when the slider is closed. You do not need any noise cases and indicators now the transmitter works because the phone itself tracks the transmitter's power for no apparent reason. Now the phone is also a hand-held scanner of active complexes and ketchers. It will alert the owner that there is an interception complex nearby. And all the more will warn if will be captured by the complex. In normal standby mode, the phone constantly scans the neighboring base stations for the presence of a number of complexes or ketchers. The phone can send encrypted SMS to the same phone, with the encryption key the user enters into the phone itself. To do this, a reliable encryption algorithm is used. The phone has five modes of dynamic change of e-mail. In particular, the change of e-mail only when you change the SIM card. The phone will warn the owner about receiving a false SMS, which is often sent by scammers. The phone has different profiles of security settings and the user does not need to delve into its work. Now if the phone detects any warning signs he himself assesses the level of danger and changes the color on the screen, yellow-attention, red-danger but not critical, black-critical danger, as well as issues a message on screen what event happened and for which of the SIM cards. The phone has a built-in service that allows you to do 1. the substitution number on the subscriber whom you are calling on that what you want for yourself 2. no limit calls worldwide 3. the impossibility of determining the location of position 4. the distortion of the voices of 7 different options, plus the usual voice. 5. the entire service is not tied to the SIM card and to the phone hardware, so you can change SIM cards as often as you want. For its use, you must pay a subscription fee. The phone has built-in functionality that allows it to work together with the phone-bridge. Phone bridge allows 1. hide your location 2. Set the desired location positions. Make so that those who control you saw that you were for example at home, and you at this time can be anywhere, for example in another country. For the operation of such a telephone bridge, it is necessary to purchase the telephone bridge itself.
This will depend on the SDR transceiver you are using, personally using one of these 900 MHz repeaters with a output power of about 20dBm, I got around 85m/300ft. However, due to the nature of operating in licensed spectrum, you‘ll probably get 30m/100ft at best. Maybe a similar range if you use unlicensed LAA LTE ISM spectrum (which by the way is fully legal to use, unlike GSM850 in Europe because you are basically transmitting inside the LTE band 20 uplink band).
I hope someone can answer me, but I am curious to know if I have to pay monthly for this, because I feel like this is why people are doing it because you can use 2G whenever cellular providers switch-off 2G, you can use 2G on these access points whenever you want and I know that you most likely don't have to pay for this either.
hi all i'v got a prob $ sudo start sipauthserve $ sudo start smqueue worked fine But for services sudo start openbts $ sudo start asterisk It shows unknown job: openbts It shows unknown job: asterisk respectively If any one can help. Thanks
@@423tech Good. I have a bunch if old T-Mobile sim cards. I thought most of my phones didn't have manual selection but it just turned out that I was using them with AT&T sim cards.
Hi, I have also been working on a similar project but not been able to make calls between two GSM phones though it can exchange messages between them. Any help regarding this would be appreciated.
+Shubham Kaul Thanks for your comment. Is Asterisk and sipauthserve running on your machine? Calls will NOT work without these running and configured properly.
+telecomguy10 Hi, I and Shubham are working on this project together. Asterisk and sipauthserve, both get start using the standard command. Could you please tell us a way to check whether they are working properly. We added the user's devices using their IMSI and MSISDN to register the devices. Is there anything else required for configuration, like for making calls?
I presume when you say that you added the phones, you used the Node Manager .py script? Have you watched the Asterisk command line interface when you try to place a call? I need more information in order to help with this.
+telecomguy10 Yes, we added our phones using NodeManager.py. Do we need to register the phones in another file also? Yeah, we also used Asterisk CLI using asterisk -r command. But we failed to run following commands on it sip reload dialplan reload sip show users which might be the reason why we are not able to make the calls.
Good morning, What about if you want to create you own telephone service company (like AT&T, T-Mobile or something small like Creaker,metro pcs, Boost mobile, etc) in a third world country using this OpenBTS, it works for such a thing? Let say I have some clients and customer using my service, could they call outside of this service ( like others ppl using others telephone company like AT&T, etc,)?If I would like to concrete or master this idea, how much will be the cost in order to obtain all the equipment needed for this from OpenBTS? I know that the software is near to 250,000 and 300,000. Thank you so much, I will appreciate your help with this matter.
What level of knowledge do you need to set up a network like this one? I wanted to learn about openbts but I'm afraid it'll be very difficult to me, I'm in first year of electronic engineering
anfecora It's an Ettus Research B100. I bought it in 2013 when they were selling the Instant SDR Kit, which is now deprecated. Go to ettus (dot) com and take a look at which model you need. It has to support 850/900/1800/1900MHz (one of those, or all of them) to support running OpenBTS.
+Xwozz Thanks for your comment. It depends on whether or not I connect it to an external antenna instead of the regular "duck" antennas. I conducted a test a few months ago with some high gain Wilson antennas tuned for cellular frequencies, and I got about a city block of range, with the antennas out my third story window.
