TEKO CPRI/DAS Point of Interface
The TEKO CPRI Point of Interface (POI) is an integrated, low-power, digital RADIO that terminates a
CPRI link from an XRAN Adaptive Baseband server. The TEKO CPRI POI can terminate one/two
MIMO carriers or two/four SISO carriers depending on the specific carrier allocation. The CPRI POI
performs analog-to-digital (A/D) and digital-to-analog (D/A) conversion and provides low-power analog
output/input.
The TCPRI POI is composed of two boards:
•
A digital board, converting the digital baseband signals from the XRAN Adaptive Baseband server
into radio frequency (RF) signals.
• An RF board, distributing RF signals from the digital board to the TEKO DAS Platform.
For full specifications, see TEKO DAS Platform - Master Unit Components.
