2G Base Station Tutorial - Part Two: Connect Phones, Make Voice Calls, Send SMS's, Use GPRS Data

[@alch3myau]

Always quality !

[@crusader_]

I have no clue whats going on here but all the titles seem very cool and I always watch the videos for a while. Could somebody this time tell me what's going on?

[@RobVK8FOES]

Hi, and yes, I can answer that question for you. In this video, I am demonstrating the operation of a private 2G cellular base station, by connecting real mobile phones to it :)

[@Black_Ghost69]

​@@RobVK8FOES so basically you do not have to pay to recharge ur sim

[@RobVK8FOES]

@Black_Ghost69 Yes, more or less that is what I am doing. It's actually a form of hacking called "man-in-the-middle false base station attack"

[@crusader_]

Interesting. How'd you suggest one gets started with GSM and this stuff? I have basic CCNA knowledge, understanding of the OSI model, how internet works and how protocols work.

[@RobVK8FOES]

@crusader_ Hi, while having those skills in computer networking would be advantageous, my focus is more on the RF (radio frequency) physical layer of the communication stack. A key item I use in my RF hobby is a 'software defined radio', having knowledge of what they are and how they work is essential.

Let's gooo new video just dropped :D

[@7hw]

Good luck, my friend, in this series. I was impatiently waiting for it from you, but is it possible to connect this network to the public network?

[@RobVK8FOES]

Hi. And yes, it is possible. Please go to the @Cemaxecuter channel and locate his two recent videos about connecting YateBTS to a third-party SIP/IAX provider in order to make outgoing calls. He hasn't got incoming calls working yet.

[@7hw]

@@RobVK8FOES Do you mean this video or another video? kzbin.info/www/bejne/gYexpoJupMuDd68si=FJHcs5TGjAgojteM

[@RobVK8FOES]

@7hw Yes, that is correct. There is also a part one video too

How to use my tv dish antenna to do this? Dish has a set top box can i reprogram it?

[@RobVK8FOES]

Hi. This will never be possible with satellite TV equipment I'm afraid...

[@stickfigure31]

Oh that's cool that it included Eliza, it's a "virtual therapist" (a simple chat bot that reflect what the users wrote to it) that was originally made in the 1960s. Someone made a python3 port of Eliza on github, I modified it to use as a discord bot on my discord server. I wounder can this same 2g base station set up be routed through a pbx server and/or VoIP service to allow talking to phones not on the base station? I ask because in America you can no longer get service directly for phones that use anything less 4g lte (even regular 4g is dead in some areas), so it's cool to see hobby projects make them still useful and not E-waste.

[@RobVK8FOES]

Hi. And yes, it is possible to route outgoing calls from within YateBTS. @Cemaxecuter has demonstrated this on his channel already (I collaborated with for it) So far only outgoing calls are working, he hasn't figured out incoming calls yet.

[@matrix99_rishi83]

Sir it's really cool what you are doing even though i cant understand it but sir can i ask you which linux are you using for such stuffs is it Fedora ?

[@RobVK8FOES]

Hi. I am using DragonOS FocalX R35. It is an RF hacking and software defined radio focused Linux distribution based upon Lubuntu 22.04. It is made by a friend of mine called @cemaxecuter

[@chebalid6797]

Can it do USSD?

[@RobVK8FOES]

Hi. I don't believe it can, or I haven't seen that functionality yet. But it might? Osmo-NITB-Scripts for the LimeSDR can definitely do USSD codes, I've tested it before.

[@usernotfound342]

Can deploy this station using HackRF hardware?

[@RobVK8FOES]

Hi. If you haven't seen part one of this video series, go and check it out. I explain why the hackRF can never be used as a cellular base station despite being transmit-capable. The tl;dr of it is basically that the hackRF can't transmit and receive simultaneously, which is what is needed for cellular base stations. It's only 'half-duplex', whereas the BladeRF is 'full-duplex'

[@yazidkeraichia2858]

@@usernotfound342 hackrf are not full suplex....gsm need fuln suplex card.

[@12342764]

Can you call other numbers not connected to your base station such as phones on other networks or international?

[@RobVK8FOES]

Hi. Yes, this is possible to do. You have to use a third-party SIP or IAX provider. @Cemaxecuter has done a two-part tutorial on how to do this (I collaborated with him for part two) So far, only outgoing calls are supported, he hasn't figured out incoming calls yet.

[@yazidkeraichia2858]

Yes. By using an IAX like Goip. Just attach the IAX with an original sim card. Second you have to config the Goip IAX. I have a config and script...that work well just to make an out call. I'm still working for incoming call...hard. can share may config...let me know. Maybe someone can improve the script ?😊

[@RobVK8FOES]

@yazidkeraichia2858 Hi, myself and @cemaxecuter have already demonstrated OUTgoing calls from YateBTS, do you know how to do INcoming calls? If so, please email myself or Cemxecuter (Aaron)

[@MarcoAntonio-ph5hw]

Is it possible to send SMS to people around me without necessarily having their phone numbers?

[@RobVK8FOES]

@MarcoAntonio-ph5hw Yes, it is possible, but you have to know the IMSI number of the person you are intending to SMS (you can retrieve IMSI numbers via the YateBTS telnet interface) Please see part three of my YateBTS tutorial

[@yazidkeraichia2858]

@@MarcoAntonio-ph5hw i think it's possible. I have tried this with openbts...just put * in place imsi. With yatebts i haven't test ...but there a github with a module send SMS....maybe that work.good luck

[@makisalim6760]

hello , Is it possible to connect your base station to a real station and receive text messages from phones that are not connected to your station?

What laptop would you recommend for hacking?

[@RobVK8FOES]

To be clear, I am not a hacker. So, I wouldn't really know which laptop is good for doing that kind of stuff. However, I am a software defined radio, Linux operating system and open-source software enthusiast. A laptop with plenty of CPU power, a lot of memory and the ability to boot Linux from a USB thumb drive if you're primarily a Windows user... Fast SSD/NVMe storage would be advantageous too.

Lol, me using a Mac? Never in one trillion years would I punish myself like that... I am using multiple PC's for this video, one is custom built dual CPU Xeon E5 gaming rig/server. And the one recording the video is an old Lenovo Ideacenter office PC. I also use an Asus Zenbook Flip when I am on the road

[@arduinoguru7233]

@@RobVK8FOES Nice work, I want to ask how get most distance of any radio communication method, with less power, and minimal bandwidth.

[@RobVK8FOES]

@arduinoguru7233 That's a complicated question, and it depends on what exactly you intend to do. By far, the frequency that propagates the furthest you can use right now (after getting your Ham radio license) is HF, or 'high frequency' which generally includes anything from 1.8 MHz to 28 Mhz typically. Anything from regular voice transmissions, text messages and even pictures can be transmitted at low power and low bandwidth and travel many thousands of kilometers/miles across the earth (depending on if the solar and atmospheric conditions allow for it at that time)
