GainSpan's GS1500M Module Achieves Wi-Fi CERTIFIED Wi-Fi Direct™ Certification

Enables device-to-device connections anywhere, anytime with or without a Wi-Fi® access point

pic_GS1500M.jpgGainSpan Corporation, a leader in low power Wi-Fi and Wi-Fi® connectivity for the Internet of Things and available from Glyn High-Tech Distribution, announced its low power GS1500M 802.11 b/g/n Wi-Fi module has achieved Wi-Fi Direct™ certification from the Wi-Fi Alliance®. Wi-Fi Direct enables devices to communicate directly with each other without having to connect first to an access point and be part of a traditional Wi-Fi network, thus enabling many new wireless device-to-device applications and usage models.

With a GS1500M Wi-Fi device and underlying Wi-Fi Direct mechanism, you can, for example, discover and connect a camera to a printer, a sensor to a display or a remote controlled device to one or more smartphones, all with no requirement for an access point. Additionally, you can connect several devices at once, in a one-to-many configuration. This makes it simple to print, display or share content with multiple devices in a peer-to-peer relationship, even in the absence of a Wi-Fi access point. Wi-Fi Direct allows devices to automatically discover, negotiate and connect with other devices in the vicinity, without user intervention. With Wi-Fi certified technology, users get industry-standard interoperability and security.

Wi-Fi Direct extends the GS1500M module's mode of operations which already includes Limited Access Point (Limited AP mode), and Client of an existing infrastructure network (Client/Station Mode). With Limited AP mode, GainSpan offers the capability to act as a soft access point connecting several Wi-Fi client devices and supporting packet forwarding between these devices. Wi-Fi Direct further improves the user experience by eliminating the need to setup a wireless network with an Access Point and having clients connect to the Access Point, thus providing a faster and easier way for devices to connect and communicate with each other. It uses the intrinsic capability of Wi-Fi Protected Setup which eliminates the need for a passphrase and uses either the pin or push button methods, while still being protected by WPA2 security. The GS1500M is also certified for Wi-Fi Protected Setup.

The GS1500M Features

Plessey (Now Available from Glyn) Releases an Ultra-Low Cost Version of its Award Winning EPIC Sensor for High Volume Applications

 

 

Plessey Semiconductors, now available from Glyn High-Tech Distribution, announced recently the release of the PS25451, an ultra-low cost version of its award winning EPIC™ sensor that provides remote sensing for high volume consumer markets. A novel electrode design has been devised to replace the expensive titanium dioxide electrodes currently used for the higher end, medical applications of EPIC technology.

 

The PS25451 is an ultra-high impedance, non-contact, solid state electric potential sensor that can be used for a variety of consumer electronic devices such as proximity switching of lighting, gesture based remote control of interactive toys, computer games, TVs, monitors, other appliances and presence detection for security/alarm systems.

 

The EPIC sensor is a completely new area of sensor technology and works by measuring tiny changes in an electric field in a similar way to a magnetometer detecting changes in a magnetic field even at a distance and through clothing. This enables it to Plessey_PS25451_200.jpgbe used for security motion sensors and non-contact electrical switches as well as medical applications detecting heart beats, nerve and muscle activity either by dry contact (i.e. no gels required) or contactless.

 

Dr. Keith Strickland, Plessey’s Technology Director, explained, “EPIC sensors can be used in an extremely wide variety of applications so we have created a product family that enables customers to select the most appropriate sensor solution according the application’s requirements for cost, operational range and sensitivity. The new electrode design for the PS25451 is formed on the copper track of the circuit board that is then covered by the normal protective resist.”

 

EPIC sensors are already in commercial production by Plessey Semiconductors. By adjusting the gain and bandwidth amplification circuitry, the sensors can be tuned for detection at a distance as required. Production pricing for the PS25451 is less than $1 in volumes above 50,000. It is supplied in a custom 3D package with exposed pins for surface mount assembly and measures 10mm x 10mm x 2mm, which is also pin compatible with the existing PS25401 EPIC sensor.

 

Plessey’s EPIC Sensor technology

 

The EPIC sensor, which requires no physical or resistive contact to make measurements, will enable innovative new products to be made such as medical scanners that are simply held close to a patient’s chest to obtain a detailed ECG reading or safety and security devices that can ‘see’ through walls. The sensor can be integrated on a chip with other features such as data converters, digital signal processing and wireless communications capability.

 

The technology works at normal room temperatures and functions as an ultra-high, input impedance sensor that acts as a highly stable, extremely sensitive, contactless digital voltmeter to measure tiny changes in the electric field down to milliVolts. Most places on Earth have a vertical electric field of about 100 Volts per metre. The human body is mostly water and this interacts with the electric field. EPIC technology is so sensitive that it can detect these changes at a distance and even through a solid wall.

Employing highly optimised USB interface ICs  to ensure strong performance

 

USB HUB IO MODULE USB solutions specialist Future Technology Devices International Limited (FTDI), available from Glyn High-Tech Distribution, has added to its range of connectivity offerings with two new products that address the rapidly growing popularity of the Raspberry Pi (RPi) computing platform. The TTL-232R-RPi is a USB-to-TTL Serial UART debug cabling solution that incorporates the company’s FT232RQ high performance interface IC. This is complemented by the RPi USB Hub Module, which is designed to connect to an RPi unit and expand the number of interfaces that can be accessed downstream from a host.

 

Only recently released, RPi is a simple, ultra-low cost computer board aimed at inspiring youngsters to learn the fundamental principles of programming. Running the Linux operating system, with a compact format that is the size of a credit card, it utilises a 700 MHz ARM-based processor and has a 256 MByte SDRAM memory.

 

Through FTDI’s debug cable it will be possible for laptop/desktop PCs to interface with the RPi board and perform in-depth analysis on the software application being developed. The 1 m long cable connects directly to the RPi’s serial port. This port will output kernel debug messages to be acquired by the PC. The FT232RQ USB-to-Serial UART interface IC within the TTL-232R-RPi cable provides a USB to asynchronous serial data transfer path capable of supporting data rates from 300 bits/s to 3 Mbits/s at 3.3 V TTL levels. The chip handles all the USB signalling and protocol requirements.

 

The RPi USB Hub Module utilises a USB-to-UART/MPSSE IC, along with a GL850G USB hub controller IC. It provides engineers with up to 4 downstream USB 2.0 Hi-Speed (480Mbit/s) ports. Asynchronous serial data transfer rates from 300 bits/s to 12 Mbits/s at 3.3 V TTL levels are supported, while synchronous serial data rates of up to 30 Mbits/s can be dealt with on JTAG, SPI and I2C interfaces. The module has dimensions of 33.45 mm x 65 mm.

 

“The RPi concept has huge potential to nurture aspiring young engineers. Supporting it with a highly optimised debug solution is a vital part of achieving that goal. The TTL-232R-RPi enables a fast, simple way to connect with an RPi and examine what is going on when it runs a newly constructed program. Furthermore, the USB Hub Module gives a greater degree of flexibility to RPi based system designs. Both products make use of the expertise in USB conversion that FTDI’s technical team possesses,” states Fred Dart, CEO and founder of FTDI. “The RPi philosophy seems very similar to that of FTDI - making things as uncomplicated as possible so that the creativity of pupils/students is encouraged,” he concludes.

 

An operational temperature range covering -40 °C to +85 °C is supported by both the cable and the hub module offerings. All the components used in their construction are fully compliant with the RoHS directive.

 

Glyn is now accepting pre-orders for TTL-232R-RPi debug cable.  RPi_Hub_Module will be available starting in August.

Fastrax Enhances the World’s Smallest GPS Antenna Module, Continues GNSS Module Portfolio Optimisation

 

The new Fastrax UC530 GPS module with integrated chip antenna combines market-leading performance and sensitivity with extremely low power consumption

 

http://www.fastraxgps.com/showpicture.cfm?guid=275675ea-6001-492e-8fe7-6ca688f6eef5Fastrax Ltd., ), available from Glyn High-Tech Distribution and a pioneering developer of high performance GNSS receivers and Software GNSS solutions for location-aware devices, today introduced the Fastrax UC530 – a new edition of the world’s smallest OEM GPS receiver with an integrated chip antenna. The module features the same ultra small form factor as the widely popular Fastrax UC430, while providing new benefits to designers, developers and manufacturers of handheld digital devices.

 

The Fastrax UC530 features the highest sensitivity on the market (-165 dBm in tracking) and extremely low power consumption, typically only 45 mW average power. The antenna module is easily embeddable in space-restricted environments thanks to its tiny footprint of 9.6 x 14.0 x 1.95 mm and extended input voltage range of +3.0V…+4.3V. The ability to directly connect the module to a lithium battery allows hardware designers to omit cost-adding regulators. Full SMT design reduces the need for external components and

minimizes manufacturing costs.

 

The integrated chip antenna of the Fastrax UC530 exhibits significantly better radiation efficiency than small patch antennas and performs well against larger and heavier patch antennas. Its circular radiation pattern brings flexibility to hardware design. The optional connectivity to an external GPS antenna extends the applicability of the module to a wider range of devices from handheld computers to asset tracking systems. When the optional external antenna is used, the embedded antenna works as a low-cost back up.

 

The new power-saving AlwaysLocate™ mode prolongs battery life while maintaining location information, similarly to the newly introduced Fastrax IT530 GPS receiver module. Depending on the environment and motion, the module adjusts its navigation activity to balance positioning accuracy, fix rate and power consumption. In addition, the Embedded Assist System (EASY™) reduces warm-start TTFF by up to 90% with autonomously calculated ephemeris data for next three days. The additional server-assisted EPO™ file transfer extends the external A-GPS service to up to 14 days when desired.

 

“Location-aware features and applications are increasingly becoming mainstream in all sorts of digital devices, which is equally exciting for users as it is challenging for hardware providers,” said Fredrik Borgström, VP of GNSS Receivers at Fastrax. “Hardware designers, developers and manufacturers are faced with the difficult task of providing accurate and reliable positioning in all kinds of small size devices, while time-to-market and price pressure call for minimal extra engineering effort and the lowest possible cost. The new Fastrax UC530 is built with these needs in mind: a complete low-power, high-sensitivity and high performance GPS receiver with an integrated antenna. Packaged in a tiny casing, the module is easy to integrate in a wide variety of devices at low cost.”

 

The embedded jammer remover in the Fastrax UC530 helps solve issues with distorting signals due to electromagnetic interference (EMI). Active Interference Cancellation (AIC) tracks and removes up to 12 CW (Carrier Wave) type EMI sources up to -80 dBm. Also embedded is the LOCUS™ logger function, which stores location information in the internal memory of the Fastrax UC530. With a typical log interval of 15 seconds, log capacity is 16 hours.

 

Fastrax UC530 will be available from Glyn by end of July 2012. Glyn is now accepting pre-orders.

Telit Publishes White Paper on GPS + GLONASS, Shows Tremendous Improvement in Positioning

 

Telit_GPS_GLONASS_wp_200.jpgExperts at Telit decided to test what impact the Russian Global Navigation Satellite System (GNSS) has on satellite navigation and positioning. They conducted tests in Los Angeles and London to see the relevance of Glonass for the whole world. The results clearly showed that the combination of GPS and GLONASS, found in modules like Telit's SL869, improves positioning tremendously.

 

At the end of 2011 the Russian government announced that GLONASS, the Russian Global Navigation Satellite System (GNSS), is fully operational and has global coverage. Experts at Telit decided to test what impact this has on satellite navigation and positioning. They conducted tests in Los Angeles and London to see the relevance of GLONASS for the whole world.

 

The results clearly showed that the combination of GPS and GLONASS improves positioning tremendously. Especially in urban canyons with huge skyscrapers the receiver had the ability to track at least four satellites and thus calculate a fix – which was impossible to guaranty using only GPS. Thanks to the SL869, a newly released Global Navigation Satellite System (GNSS) module from Telit that has access to both GLONASS and GPS, blind spots were reduced and navigation performance was radically improved. This white paper shows the test set-up and examines the results. For the future further tests are planned, for example in South Africa.
