Wireless Comunications Tiny Bluetooth smart wireless module Murata has announced the LBCA series of ultra compact and ultra low power consumption Bluetooth Smart modules. Measuring only 5.4x4.4 mm (LBCA2BZZFZ without antenna), these surface mount devices are a quarter of the size of previous models and are aimed at the increasingly wide range of wearable devices, especially wristband-type applications, such as fitness monitoring, smart watches and remote controllers. Conforming to the Bluetooth 4.0 low energy protocol, the modules are available both with (LBCA2HNZYZ) or without a built-in antenna (LBCA2BZZFZ)). With a 0 dBm output power, the modules typically have a range of 30 metres. Interfaces include UART, SPI, I2C and GPIO. Peak current consumption is up to 4.5 mA, dropping down to a deep sleep current of 0.6 μA or less. Average current consumption during communications is 6 μA when 20 bytes of data are transmitted once per second. It is anticipated that with this use case up to 4 years operation is possible when using CR2032-type coin cells. The modules come certified to FCC/IC, CE and TELEC regulations, significantly helping to reduce the development costs and time-to-market for new designs. Murata www.murata.eu Wireless chip is compatible with the 868MHz Wireless M-Bus Lapis Semiconductor has developed a wireless communication IC compatible with the 868MHz Wireless M-Bus, the European smart meter communication standard. The 868MHz band Wireless M-Bus data transmission protocol for smart meters is likely to become popular in Germany and the surrounding countries and ultimately adopted as the mainstream communication method in Europe. It has three modes. Signals must be discriminated differently for each mode based on the operating function. The ML7406 supports the frequency band from 750MHz to 960MHz, making it also compatible with the ARIB STD-T108 standard in Japan as well as the global standard IEEE802.15.4g. The chip integrates a Wireless M-Bus packet handler designed to perform hardware-based processing of a variety of functions, such as simultaneous standby for interoperability between C and T Modes, automatic discrimination of Format A and B messages in C Mode, and address filtering that automatically distinguishes whether packets are intended for this or other devices. As a result, microcontroller operating rate is reduced by about 20% compared with conventional software-based systems, significantly cutting device power consumption. Lapis Semiconductor can supply sample software and C source code that include all of the T, C, and S Mode functions compatible with EN113757-4:2011 in the Wireless M-Bus protocol stack. An industry-standard OMS-compatible protocol stack usable without modification in OMS-based meters, along with Wireless MBus protocol analysis software, can be licensed from Steinbeis. Lapis Semiconductor www.lapis-semi.com eCall system supports GPS and Glonass Starting in 2015, the automatic emergency call function (eCall) will be required throughout Europe in all new vehicle models. Russia also plans to start the gradual implementation of a similar system that same year. To meet this demand, automotive infotainment solution provider connectivity Peiker acustic GmbH has introduced a Network Access Device (NAD) - anUMTS module that enables the exchange of data between the vehicle and its surroundings. In addition to automatically placing an emergency call to the appropriate emergency dispatch center, the device also transmits important information such as the vehicle’s location after the accident, technical vehicle data, and, as an option, the number of occupants. This helps make it easier for emergency responders to find the vehicle quickly and provide the necessary assistance. Alongside the global navigation satellite system GPS, the NAD also receives information from the Russian Glonass satellites. This allows the deployment of the systems in both Western Europa and Russia. Plus, Peiker’s prototypes were the only ones to come through the border crossing between Russia and Finland successfully. Peiker www.Peiker.com 3.5G wireless gateway connects remote devices and mobile equipment Lantronix has just launched PremierWave XC HSPA+ (3.5G), a high speed gateway and application server designed for easy mobile and remote device connecti vity. The PremierWave XC family is designed for applications in a variety of vertical markets including telematics, industrial automation, healthcare, energy or utilities. The product enables remote access and management of virtually any serial equipment or device through the use of the Lantronix device server application suite and optional custom programming environment. Additionally, the PremierWave family is critical for applications deployed in areas that do not have an Ethernet or Wi-Fi infrastructure, or for installations that have such connectivity but rely on cellular for failover backup, ensuring redundancy. It features penta-band UMTS/HSPA+, quad-band GSM/GPRS/EDGE, Ethernet-to-Cellular routing, Ethernet-to-Cellular failover and failback, and SMS capability for relay control, event notification, and tunneling. Dual network connectivity (Wired Ethernet and Cellular) offers flexibility and redundancy.
