Группа выше: Программно-определяемое радио (SDR)
Смысл: The main idea is to demonstrate that with the right open-source software and modified low-cost SDR hardware, it is possible to recreate a functional cellular infrastructure (2G/4G) for educational, research, and nostalgic purposes.
A detailed technical walkthrough on using a modified PlutoSky 7020 SDR and open-source stacks like srsRAN and Osmocom to build a private 4G and 2G mobile network.
Смысл: The main idea is to demonstrate that using Software Defined Radio (SDR) and open-source software, it is possible to replicate a professional cellular operator's infrastructure (including VoLTE and SMS) in a home laboratory environment for educational and experimental purposes.
A technical walkthrough on using SDR, Open5GS, and Kamailio to launch a private 4G LTE network supporting voice calls and SMS.
Смысл: The main idea is to demonstrate that with open-source software and basic radio equipment, it is possible to emulate an obsolete analog cellular standard (NMT-450) to bring vintage hardware back to life for educational and hobbyist purposes.
A technical tutorial on using Osmocom-analog and UHF radios to build a home-based NMT-450 analog cellular network for vintage phones.
Смысл: The text demonstrates that with modern SDR hardware and open-source software like Osmocom/OpenBSC, anyone can easily create a functional local GSM network for research and nostalgia, providing a bridge between modern technology and legacy cellular standards.
A technical guide on using a USRP SDR and DragonOS to quickly deploy a private GSM network supporting calls, SMS, and GPRS internet for legacy mobile phones.
Смысл: The text demonstrates that with modern SDR technology and open-source software, it is possible to emulate obsolete cellular standards like AMPS to bring vintage hardware back to life for educational and historical purposes.
The author successfully revives a 1990s Motorola analog phone by building a local AMPS network using a Raspberry Pi and an SDR transceiver.
Смысл: The main idea is to provide a comprehensive technical tutorial on creating a functional, private 4G LTE network for educational and experimental purposes using open-source software and SDR hardware.
A technical guide on deploying a private 4G LTE network using srsRAN software, SDR hardware, and programmable SIM cards to provide local internet connectivity.
Смысл: The text provides a detailed technical guide on how to implement a 4G LTE modem using Software Defined Radio (SDR) and srsRAN software. It explains the necessary hardware, software compilation, and specific network configuration required to connect a computer to a commercial cellular network without using a standard commercial modem.
A technical guide on using an SDR and srsUE software to connect a Linux PC to a commercial 4G network via a physical SIM card.
