Product Functions
As a component of an eNodeB, the ZXSDR R8502 and a BBU operate together to establish and configure cells and send broadcast information.The system implements UE access and radio link transmission through the air interface.It provides the following functions:
Supports band 40/41 and meets the TD-LTE requirements of establishing networks on the 2.3G frequency bands.
Supports 2T2R.
Supports a maximum output power of 2×10 W.
Supports a maximum of two carriers, 10/15/20 MHz carrier bandwidths in TD-LTE, and multi-carrier aggregation.
Supports 64QAM, 16QAM, and QPSK modulation and demodulation schemes in uplinks and downlinks.
Supports a built-in or external antenna.
Communicates with the BBU to exchange I/Q data and operation and maintenance messages through an optical fiber.A maximum of six ZXSDR R8502s can be cascaded through optical fibers.
Support remote operation and maintenance.
