Better Than Bluetooth?

Wireless communication protocol transmits data up to 60 m

A new wireless communication protocol developed by Nanotron (Berlin) may allow devices to transmit data over greater distances with lower power requirements than existing technologies. Dubbed nanoNet, this advance uses a multidimensional multiple-access transmission system operating at a frequency of 2.4 GHz in the license-free ISM band. Featuring primarily analog signal processing, it can send interference-free information up to 60 m indoors, and 700 m in free spaces, with a power of just 10mW.

Developed after 5 years of research, the nanoNet transmitter is designed to require a minimal number of external components to form a fully operational bidirectional wireless communication node. Eliminating the need for a separate antenna, it can be installed using pick-and-place machinery. The unit operates in ambient temperatures of -40° to 85°C and features a maximum data-transmission rate of 2 Mb/sec. In addition to its already low power consumption, the transmitter also incorporates a power-down mode for increased efficiency.

NanoNet technology is particularly suited for battery-powered applications that require long product life. "Our chip can be used in any medical device where designers want to eliminate cables while maintaining low power consumption and radiation output," says public relations director Christian Buck. "A major area we're looking at are devices used to control heart rate,"he adds.

Highlighting the importance of this development, the NanoNet TRX transceiver was recently named one of the top products of the year by German engineering trade journal Elektronik. And though Nanotronis happy with this achievement, it is certainly not resting on its laurels in regard to product development. The company is already hard at work designing the next generation of nanoNet products, devices that will feature higher data-transmission rates with increased reliability.
