Texas Instruments and AirHop Communications Announce Advanced SON Software Optimized for TI's KeyStone-Based Small Cell Solutions

Texas Instruments Incorporated (TI) (NASDAQ: TXN) and AirHop Communications, the leading provider of advanced radio access network (RAN) intelligence solutions for heterogeneous networks (HetNet), today announced their collaboration to integrate AirHop's eSON™ advanced self-organizing network (SON) software on TI's KeyStone-based small cell System-on-Chips (SoCs). With this integrated solution, developers using TI's TMS320TCI6612, TMS320TCI6614 and TMS320TCI6636 SoCs will be able to design small cell base stations that will facilitate operators' ability to deploy heterogeneous networks.

To meet escalating demand for mobile data, network operators are turning to small cell base stations to increase capacity and complement existing macrocell networks. The resulting HetNet requires SON technology specifically designed for small cell networks to actively optimize system capacity and manage inter-cell interference. The combined TI and AirHop solution helps base station vendors get to market quickly with high performance small cells that satisfy telecom operators' requirements for HetNet applications.

TI's scalable KeyStone architecture includes support for both TMS320C66x digital signal processor (DSP) generation cores and multiple cache coherent quad ARM® Cortex™-A15 clusters, for a mixture of up to 32 DSP and RISC cores. In addition, TI's KeyStone architecture includes fully offloaded, flexible packet and security coprocessors and capacity expansion for SoC structural elements such as TeraNet, Multicore Navigator and Multicore Shared Memory Controller (MSMC). These structural elements provide a seamless integration between the DSP and ARM RISC cores, allowing base stations developers to fully utilize the capability of all processing elements, including the cores and enhanced AccelerationPacs.

AirHop's eSON software delivers multi-cell coordination and optimization that can be deployed in fully distributed, centralized or hybrid architectures and, for maximum flexibility, can be located anywhere in the core network cloud and on a variety of network edge devices. TI's KeyStone multicore SoC architecture enables more efficient measurements from the lower level PHY stack, required by the higher level SON algorithms, resulting in optimized SON solutions for customers.

"AirHop is a technology leader in helping carriers and equipment vendors use SON to optimize capacity and manage the interferences in small cell deployment, making us a natural choice to work with TI on its LTE small cell SoCs, which are the most competitive in the industry," said Yan Hui, co-founder and CEO of AirHop. "As TI's vendor of choice for SON software, we have worked closely with TI to optimize our software for its KeyStone-based small cell SoCs and look forward to delivering software solutions to TI's customers."

"The management, configuration of and interference cancellation between macro cells and small cells is one of the largest barriers to mass deployment of small cells today," said Sameer Wasson, business manager, wireless base station infrastructure, TI. "TI's small cell SoCs are in production and in development with leading base station vendors today, and with this integration of AirHop's SON software, we can truly enable operators to overcome some of the early challenges of HetNet deployments and advance the installation of small cells."

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications.

The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications.

“We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner Engin…

IDEC Releases New Line of High Efficiency Power Supplies

IDEC Corporation announces the PS5R-V line of DIN-rail power supplies, offering their customers high-efficiency in a compact form factor at competitive prices. These power supplies suit a wide range of needs in the industrial marketplace, and carry all of the required certifications necessary for use in these demanding applications. This next generation of the industry standard PS5R power supply family has updated features and specifications to meet current and future needs.

The PS5R-V line of power supplies includes 10W, 15W, 30W, 60W and 120W versions, with additional versions coming soon.

The reduced form factors combine with DIN-rail mounting to free up valuable control panel space and reduce installation costs.

Operating temperature ranges up to -25 to +75 degrees C offer more versatility. These extended operating temperature ranges often allow these power…


TURCK is now offering the option to completely shield M8 picofast ® cordsets by connecting a braided shield directly to the coupling nut. This provides a cost-effective and reliable connection with 100 percent cable and connector shielding, which protects against electromagnetic and radio frequency interference.

The 3 and 4-pin cordsets are available with flexlife ® PVC or PUR jacketed cable. All connectors deliver IEC IP 67 protection.

The M8 picofast line, like most TURCK cordsets, provides male or female, straight and right angle connectors, standard and custom lengths, and pigtails or extensions. Fully encapsulated mating receptacles are also offered, completing the system.
