Fast wireless standard and central management for Industrial Wireless LAN

The Siemens Industry Automation division has developed a package of coordinated industry-compatible components for wireless communication complying with the WLAN (Wireless LAN) standard IEEE 802.11n. The new range consists of the access points SCALANCE W786 and W788, the client module SCALANCE W748 and the IWLAN controller SCALANCE WLC711. The main advantage of the components is the data rate of up to 450 Mbps.

The high data rates of the new IWLAN components from the Siemens Industry Automation division allow even large amounts of data to be transferred securely and quickly. Potential fields of use include applications with video, visualization or voice data. With the use of Mimo (multiple input, multiple output) technology with three antennas per wireless interface, these SCALANCE W products achieve long ranges and a high degree of robustness in wireless communication.

This means that the Siemens components are suitable not only for wireless communication in an automation environment, but also in industry-related areas such as logistics, airports, road and underground railway tunnels or crane systems. Typical applications for wireless data transmission via IWLAN are the monitoring of safety-critical areas for the protection of persons or the monitoring of processing and storage procedures in high-bay storage systems.

The access points are available in three versions. With an extended temperature range and extremely resistant housing, SCALANCE W786 is suitable for outdoor use. SCALANCE W788 is designed for indoor operation with degree of protection IP65 and for a control cabinet with degree of protection IP30. With the client module SCALANCE W748, any stationary or mobile devices with Ethernet capability can be integrated in the wireless network.

The IWLAN controller SCALANCE WLC711 represents a significant expansion of the portfolio. The controller allows central configuration and monitoring of up to 32 access points and client modules. A controller-based wireless network solution reduces effort and costs during commissioning and operation of larger IWLAN installations. With parallel operation of two SCALANCE WLC711 IWLAN controllers, the availability of the communication network can be increased. The device is installed in a housing without a fan and is suitable for DIN rail mounting. In addition to all this, there are the new access points and the client module also with integrated controller functionality in the versions SCALANCE W786C, SCALANCE W788C and SCALANCE W748C.

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
