MEMSIC's wireless sensors connect the physical environment with enterprise management
and information systems to provide advanced monitoring, automation and control solutions
for a range of industries. The applications for wireless sensor networks are almost
limitless with many industries and applications having specific technology requirements
such as reliability, battery-life, range, frequencies, and topologies, size of the
network, sampling rate and sensor use.
To address the unique requirements of individual applications, MEMSIC provides a
broad portfolio of wireless sensor network products such as our eKo, MICAz, TelosB,
and IRIS Wireless Development Kits that allows our customers to choose the optimal
solution for their industry, application and geographical requirements. MEMSIC's
technology is proven in numerous deployments and is ideal for systems where multiple
sensors nodes are required.
The radio technology used by MEMSIC in their wireless modules supports domestic
and international frequency bands in the 433 MHz, 868-915 MHz, and 2.4 GHz bands.
Multiple channels are available in each band under software control, resulting in
a flexible solution for customer applications. The processor has full control of
radio features, and can control parameters such as transmit/receive mode switching,
channel selection, output power, and radio standby mode. Data packets routed through
the radio are error correction encoded, with the ability to listen to the channel
via RSSI measurement to determine if the channel is clear to send data. Depending
on choice of radio and configuration, data rates of 19.2kbps to 240kbps are available.
Both the radio and processor support deep sleep modes for maximum power savings.
The motes are designed to support battery operation from 2.4V to 3.6V, with an integral
battery voltage monitor.
MEMSIC's wireless sensors and motes enable OEMs and system integrators to bring
end-to-end systems to market quickly and economically. Building on MEMSIC's recent
acquisition of Crossbow Technology’s expertise as the leader of wireless sensor
networks, MEMSIC is committed to making the future of WSN technology a reality.
