Family of modules provides all-in-one LTE connectivity for M2M French 4G chipmaker Sequans Communications has introduced a new line of LTE modules with a complete RF front end and key interfaces in a single, compact package for M2M designs. The EZLinkLTE modules are based on Sequans’ LTE baseband and give device designers a plug-and-play, all-in-one LTE connectivity solution that significantly reduces development cost and time to market. The first EZLinkLTE module, sampling now, is the VZ20Q, which is one of the first modules in the industry to support both LTE bands 4 and 13. The baseband chip at the heart of the new module is Sequans’ SQN3120 Mont Blanc chip that was certified by Verizon Wireless in 2012. The chip is compliant with 3GPP release 9 and it delivers category 4 throughput of up to 150 Mbps in the downlink. Starting with the SQN3120 chip, the VZ20Q integrates all other elements necessary for a complete LTE modem system. These include an LTE-optimized RF transceiver provided by Sequans’ RF partner, Fujitsu Semiconductor, a complete dual-band RF front-end for bands 4 and 13, LP-DDR SDRAM, embedded boot Flash, and VC-TCXO, all in a single, surface-mountable package with a very compact footprint, 17 x 24 x 2 mm. “Our EZLinkLTE modules provide great value to device designers in terms of cost savings and reduction of development risk and time,” said Georges Karam, CEO of Sequans. EZLinkLTE modules are designed to provide a comprehensive LTE connectivity solution for the design of connected consumer electronics devices, tablet and laptop computers, machine-to-machine devices, and other applications featuring embedded LTE connectivity. Sequans Communications www.sequans.com Dual-band Ethernet port adapter with external stub antenna connectBlue’s Ethernet port Adapter RWE251s features Wireless LAN (WLAN) dual-band functionality and an omnidirectional external stub antenna, making the unit suitable for use in both the 2.4GHz and the 5GHz ISM bands with no restrictions as to its position. Based on WLAN IEEE 802.11 a, b, g, n (also commonly referred to as Wi-Fi), the rugged RWE251s can be used in industrial and medical applications where the Ethernet cable needs to be replaced with a robust wireless connection. The ready-touse RWE251s optimizes the installation process as well as lowers the installation costs in demanding applications. Dualband support makes it easier to identify interference free channels and connect to networks that utilize both the WLAN 2.4 and the 5GHz radio bands and thereby coexistence between wireless technologies is facilitated. The 11cm external stub antenna with RPSMA connector is omnidirectional. It is also possible to place the RWE251s inside and the stub antenna outside a metal cabinet giving maximum systems in design possibilities. The product is IP65-classed and can operate in the extended temperature range of -30 to +65ºC. Configuration of the device is simple and intuitive thanks to the SMART configuration mode. The RWE251s supports WEP64, WEP128, WPA-PSK, WPA2-PSK, TKIP, CCMP (AES), LEAP, PEAP and is radio type approved for US (FCC), Europe (ETSI R&TTE) and Canada (IC RSS). Further, the RWE251s is configurable to optimize for Profinet. connectBlue www.connectblue.com ZigBee single-chip solution connects smart lighting to infrastructure To simplify the development of ZigBee wireless connectivity-enabled smart energy infrastructure, home and building automation and intelligent lighting gateways, Texas Instruments Incorporated announced the availability of the CC2538 system-on-chip (SoC). The industry’s most integrated ZigBee solution, the CC2538 is cost-efficient with an ARM Cortex-M3 MCU, memory and hardware accelerators on one piece of silicon. The CC2538 supports ZigBee PRO, ZigBee Smart Energy and ZigBee Home Automation and lighting standards to deliver interoperability with existing and future ZigBee products. The SoC also supports IP standards-based development using IEEE 802.15.4 and 6LoWPAN IPv6 networks for maximum flexibility. The CC2538 development kit (CC2538DK) provides a development platform for the CC2538 allowing users to see all functionality without additional layout. It comes with CC2538 evaluation modules (CC2538EMK) and mother boards with an integrated ARM Cortex-M3 debug probe for software development and peripherals including an LCD, buttons, LEDs, light sensor and accelerometer for creating demo software. The boards are also compatible with TI’s SmartRF Studio for running RF performance tests. For more information on the CC2538, available development kits and Z-Stack software see: Texas Instruments www.ti.com Wireless data logger connects to the cloud through Bluetooth LE MSR Electronics has unveiled the universal MSR145 mini data logger, a wireless unit able to connect via Bluetooth Low Energy and a smartphone, a PC or the BLE receiver box, to the manufacturer’s web-based “MSR SmartCloud” service for mobile data monitoring. As well as enabling the wireless monitoring of measured data and fast readings of measured values, the unit displays its readings on a 96x64 pixels wide viewing angle OLED (organic light-emitting diode) graphic display measuring 22.14x15.42mm. The free MSR smartphone app can be used to recall the current and last recorded values at any time. A smartphone, a PC or the BLE receiver box by MSR Electronics GmbH transmits the measured data to MSR SmartCloud, if required. MSR Smart- Cloud facilitates the storage of measured data on a server via the Internet, allowing the user to view, print or download the measured values of their data loggers to a PC for a detailed analysis, wherever they are. The display is switched on and off manually; the desired display data can be configured in the MSR PC software program “Set up”.
