Tests of the technology begins on Monday at "Supermax 2", a high-security unit for extremist-related offenders at Goulburn prison.
Authorities say the technology jams the frequencies that transmit mobile phone signals and follows a similar program implemented at Lithgow jail in 2013.
"Contraband mobile phones are an issue for prison authorities around the world, because the phones are as small as a key ring and can be easily concealed," Corrective Services NSW Commissioner Peter Severin said in a statement.
"This technology will make a significant improvement to the security at Goulburn because even if an inmate manages to smuggle a phone in, it will be completely useless for communication because it can't connect to the network."
If initial tests are successful, a two-year trial of the technology will take place.
