For LTE (Long Term Evolution) and WiMAX, Loughborough-based CommAgility has announced a complete digital baseband module.
To be known as AMC-2C87W3, the full-size Advanced Mezzanine Card includes L1 PHY (physical layer), L2 RLC/MAC (radio link control/media access control), transport - including all backhaul and air interface security, and antenna connection requirements of eNodeB.
"It provides end-to-end data handling from raw radio IQ data through to backhaul IP packets," said the firm. "The module incorporates the WinPath3 Network Processor from Wintegra, which provides a flexible means of handling the real-time IP packet and security processing and L2 RLC/MAC demands of wireless base stations."
WinPath3 supports symmetrical multi-processing with 12 cores, with 64 parallel hardware threads for the user plane and two control processors for the control plane.
For L1 PHY processing, two Texas Instruments TCI6487 multi-core DSPs running at 1.2GHz provide a single sector 10MHz, 2x2 MIMO LTE system.
CPRI/OBSAI, DSP co-processing and board control logic are mopped up in a Xilinx Virtex 5 FPGA.
Three SFP optical sockets are configurable as CPRI/OBSAI or Gigabit Ethernet, and provide connections to remote radio heads and backhaul.
Timing and synchronisation support is provided by an integrated GPS or IEEE1588 capability with optional OCXO-based holdover
The module will be available in March.
