Zetron tests CSSI with Harris P25 Phase-II network

Zetron’s Advanced Communications (AcomEVO) system using the Project 25 (P25) Console Subsystem Interface (CSSI) has successfully completed testing with Harris Corporation’s Project 25 (P25) Phase-II radio infrastructure.

Project 25 Phase II offers customers twice the spectrum efficiently of Phase I because it uses time division multiple access (TDMA), a channel-access method that puts two voice calls in a 12.5 kHz-wide channel. Phase I uses frequency division multiple access (FDMA), which allows only one voice call in a 12.5 kHz channel.

“Zetron’s successful testing with Harris’s P25 Phase-II network adds yet another partner to the list of those whose open-standards-based solutions our systems support,”  said Zetron VP of Product Management and Marketing Kathy Broadwell. “As radio manufacturers embrace P25 Phase-II technologies, Zetron is ready to test and deploy with them.”
