WizYa's high-performance Layer-1 implementation supports CPRI connectivity between CommAgility's AMC-2C6670 and AMC-RF2x2 modules

CommAgility, a manufacturer of signal processing modules for wireless baseband applications, has said that WizYa Technologies, a developer of 4G cellular solutions, has demonstrated a complete LTE eNodeB system for advanced wireless networks, running on its AMC-2C6670 and AMC-RF2x2 AdvancedMC modules. By integrating the system or its components into their LTE designs, wireless equipment manufacturers will be able to cut time to market and development effort.

The LTE eNodeB system is comprised of WizYa's high-performance Layer-1 implementation, which supports CPRI connectivity between CommAgility's AMC-2C6670 and AMC-RF2x2 modules. The implementation is integrated with a third party Layer-2/3 protocol stack. Interoperability was verified with commercial LTE user equipment (UE), as well as with industry standard tools and test equipment.



WizYa's Layer-1 implementation is optimised from the ground up for Texas Instruments’ KeyStone-based TMS320C66x generation of multicore DSPs, extensively utilising on-chip accelerators, Navigator hardware queues, and high-speed interfaces such as Serial RapidIO. 

The implementation is designed with modularity in mind, and supports all LTE bandwidth configurations up to 20MHz, including FDD and TDD, with up to 4x4 MIMO and multiple carriers. It can be customised in response to customer requirements for various applications including macro/micro, pico, and femto eNodeBs.

The AMC-2C6670 is a signal processing AMC card for 4G wireless baseband and test equipment solutions, including LTE and LTE Advanced. It includes two Texas Instruments TMS320C6670 DSPs with an option for SFP+ connections direct to the AIF2 interface of one DSP to support CPRI. The module provides a Xilinx Virtex-6 LX240T FPGA, and an IDT CPS-1848 Gen2 SRIO switch provides a 20Gbps per port Serial RapidIO (SRIO) infrastructure. An integrated GPS receiver for timing synchronisation is also available. 

The AMC-RF2x2 is a wideband, highly flexible dual channel RF card in AMC form for LTE and LTE Advanced applications, which provides 2x2 MIMO on a single card. The standard hardware provides two matched RF ports supporting both FDD and TDD modes across all the LTE and LTE Advanced bands, with bandwidths from 1.4MHz through to 40MHz. A CPRI interface for RF data allows connection to a wide range of baseband implementations, with module control via Ethernet or CPRI.
