Alpha Micro showcases u-blox GSM/GPRS modules, Axsem radio systems on chips and GainSpan low power embedded WiFi solutions

M2M specialist, Alpha Micro Components, will be showcasing its wide range of M2M wireless devices including GSM/GPRS and GNSS positioning receiver modules from u-blox, low cost, low power RF ISMSoCs from AXSEM and very low power embedded WiFi solutions from GainSpan at Fortronic 2013, 25thJune 2013, Williams F1 Conference Centre, Grove, Wantage, Oxfordshire, OX12 0DQ.

A popular free one day technical forum for engineers, Fortronic will feature the very latest in RF and wireless telemetering, wireless and sensor technologies, antenna design, large low power wireless networks and short and long wave wireless technologies.

New to Alpha Micro’s stand will be the SARA-G3 series of u-blox GSM/GPRS modules featuring extremely low power consumption and a miniature LGA form factor. SARA-G3 modules are interchangeable, and have been designed with the diverse needs of M2M customers in mind.

SARA-G350 is a full feature quad-band GSM/GPRS module with a comprehensive feature set including an extensive set of internet protocols (TCP, UDP, HTTP and FTP). SARA-G350 also provides fully integrated access to u-blox GPS/GNSS positioning chips and modules, along with embedded A-GPS (AssistNow Online and AssistNow Offline) functionality.

SARA-G300/G310 modules target high volume, cost sensitive applications, and provide “bit pipe” GSM/GPRS functionalities while minimising the customer’s total cost of ownership. Functionalities requiring dedicated and expensive hardware components are eliminated where they are not needed, or can be implemented in the host processor.

Other modules to be showcased on the stand include the u-blox positioning receiver modules – Amy, Max, Leon and Lea.

Also featured on the stand will be the Axsem AX5043 70-1050 MHz narrow-band, high performance, ultra-low power RF transceiver IC - the world's highest performance integrated RF transceiver, with126 dBm sensitivity at 1.2 kbps with 43dB adjacent channel rejection achieved with only 9.5 mA RX current.

Key benefits include 9.5 mA RX current, -126dBm sensitivity, 45dB adjacent channel rejection @ 1.2kbps/6.25 kHz channel BW/868 MHz/FSK; ultra-low power without sacrificing link budget or selectivity; carrier frequency 70-1050 MHz; constant TX output power over the full VDD range of 1.8 - 3.6V; fully autonomous lowest power wake-on-radio mode (500 nA); packet RX/TX without microcontroller intervention and arbitrarily configurable protocols e.g. HDLC or Wireless M-Bus (S, R, T).

Alongside u-blox and Axsem, Alpha Micro will be exhibiting the GainSpan GS2011M module, which provides a quick, easy, and cost effective way for device and appliance manufacturers to add Wi-Fi connectivity to their products. The module provides a high speed serial interface connection to an embedded design built on an 8/16/32-bit microcontroller, achieving up to 40 Mbps throughput over an SDIO interface.

The GS2011M is an ideal solution for organisations with limited Wi-Fi or RF expertise or for those seeking faster time-to-market, as it reduces RF design time and removes the burden of testing and certification. The module is IEEE 802.11b/g/n compliant, and meets worldwide regulatory and Wi-Fi Alliance certification requirements.

The module includes two analog to digital converter (ADC) pins for connecting energy measurement and other sensors. It runs the full Wi-Fi and TCP/IP networking stacks on module, completely offloading the host microcontroller. The module supports a complete suite of security protocols, also without tasking the host microcontroller, including WPA/WPA2-Enteprise and Personal security modes, legacy WEP encryption, and upper layer security protocols such as TLS/SS and HTTPs. Alternatively, it can be run self-contained without a host.

For ease of provisioning, the module can be set up simply and easily from a smartphone or laptop through the innovative Limited AP mode or with Wi-Fi Protected Setup (WPS).
