N.A.T. simplifies and accelerates LTE

N.A.T. announced the NAMC-ODSP-W, a powerful new AdvancedMC module that makes it faster and easier for telecom equipment and service providers to test and demonstrate LTE, LTE Advanced and 5G systems that require MIMO and Massive MIMO technologies. The new module enables developers to implement complete RF to Layer 3 wireless base station functionality on a compact, single-wide computing module.

Combining four RF channels with DSP, FPGA and quad-core ARM based processing, this module includes a comprehensive range of software including a Linux operating system, L2/L3 stack, virtualized core network software and software defined radio PHY firmware. Clocking can be implemented via on-board GPS circuitry, an external reference clock input on the front panel, a TCLKA-D interface (receive or transmit) on the backplane connector, or an on-board Stratum-3 high precision oscillator. A variant of the NAMC-ODSP-W offers a dual SFP connector to the front panel to enable a CPRI link to external RF, allowing the module to be used in conjunction with third party remote radio head solutions.

The NAMC-ODSP-W can run a variety of cellular software provided by Octasic and its trusted software partners. Octasic has developed physical layer or Layer 1 software on the Octasic OCT2224 DSP for multiple cellular standards including GSM/GPRS/EDGE, CDMA2000, UMTS/HSPA, LTE-FDD/TDD and radio utility system. RUS is specialized software that provides network listen and RF player/recorder functionality on all cellular standards. RUS also includes a base station automatic synchronization system module, which can be used to synchronize the internal clock of the NAMC-ODSP-W to commercial base stations in areas that GPS and external clock sources are not available.

The standard variant of the NAMC-ODSP-W, with dual AD9361 RF-SoC devices, two channels of any cellular standard can run independently of each other. Each channel can use one of DSPs or a pair for extra processing power. Similarly, the NAMC-ODSP-W variant with dual SFP connectors, can run two channels of any cellular standard and use CPRI links to communicate with remote radio modules such as the N.A.T. NAMC-SDR.

Trusted partners of Octasic and N.A.T. offer higher layer protocol stack (Layer 2/3) and core network software for GSM/GPRS/EDGE, CDMA2000, UMTS/HSPA and LTE-FDD/TDD. All protocol stacks and core network software can run on the NXP ARM processor on the NAMC-ODSP-W. All software layers (L1/2/3 and core) are fully integrated and can be delivered as a turn-key solution. The integrated solution can be used in various scenarios such as private networks, wireless surveillance and research and development.
