802.11ax WiFi Aims to Deliver Higher Throughput (Up to 10 Gbps), Better Handle High Density Scenarios

802.11ax WiFi, also known as High-Efficiency Wireless (HEW), aims to improve the average throughput per user by a factor of at least 4 times in dense user environments, with a total bandwidth of 10 Gbps over 2.4 and 5.0 GHz . The new standard is still work in progress and is expected to be published in 2019. 802.11ax WiFi key features include: Backwards compatible with 802.11a/b/g/n/ac Increase 4x the average throughput per user in high-density scenarios, such as train stations, airports and stadiums. Data rates and channel widths similar to 802.11ac, with the exception of new Modulation and Coding Sets (MCS 10 and 11) with 1024-QAM. Specified for downlink and uplink multi-user operation by means of MU-MIMO and Orthogonal Frequency Division Multiple Access (OFDMA) technology. Larger OFDM FFT sizes (4x larger), narrower subcarrier spacing (4x closer), and longer symbol time (4x) for improved robustness and performance in multipath fading environments and outdoors. Improved traffic flow and channel access Better power …

LabVIEW Now Supports Raspberry Pi 2 & 3, BeagleBone Black with LINX 3.0 Release

LabView is a system-design platform and development environment with a graphical programming syntax that “makes it simple to visualize, create, and code engineering systems”.  It’s often used with National Instruments hardware such as myRIO, but LabView Makerclub has also developed LINX to bring support to Arduino and chipKIT, and with the latest LINX 3.0, support for BeagleBone Black, and Raspberry Pi boards has been added. You’ll need Labview 2014 (Windows only) or greater to work with LINX 3.0, as well as one of the supported development boards. Complete Labview 2014 + board kits are also sold with the  BeagleBone Black Physical Computing Kit and Raspberry Pi 2 Physical Computing Kit both going for $89 on Digilent. LabView files are save in VI format, and the same file can be used on Arduino, BeagleBone Black, and Raspberry Pi board with minor modifications (e.g. GPIO pin number) as shown in the blink demo below. You can access the tutorials (mostly videos) for …

Embedded Systems Outlook and Trends for 2012

National Instruments has recently published a report entitled “Embedded Systems Outlook 2012 – Key Technologies and Methodologies Impacting the Embedded Systems Market” which lists technology and business trends for the development of embedded systems. Here are the key findings: Technologies & Architectures: Embedded Platforms Technology providers are developing components, modules, or even complete embedded platforms (software + hardware) with higher levels of integration and increased functionality to speed up time to market. System-on-Chip (SoC) and System-on-Module (SoM) benefit from this trend and some also embed a FPGA. Reconfigurable Computing Previously, designers chose between low-cost microcontroller or high performance CPU based on the expected performance needs of the embedded system. As cost decreases and performance increases, low cost devices such as control and monitoring systems now often come with more features thanks to the use of programmable logic. This type of flexibility can be achieved by adding an FPGA to the MCU / MPU in the embedded systems platform. Mobile Devices and …
