that's not a cellphone network that's a VHF/UHF radio repeater network. basically same idea as ham radio hilltop repeater stuff in the US, but built for private purposes, and using COTS radios capable of basic encryption.
- chongli 5y agoFrom the article: Soldiers seized 167 antennas, more than 150 repeaters and thousands of cellphones and radios that operated on the system. It sounds like it had both radio and cell bands if phones were able to use it.
- CompuHacker 5y agoThere exist very fancy radios that look somewhat like GSM-alike cell phones, if I'm not mistaken.
- walrus01 5y agothere are also cheap vhf/uhf handheld radios from china which integrate a basic 2G GSM radio, SIM card slot, and can talk to common euro/asian 3GPP radio bands.
