Coin cell transceiver targets short-distance wireless data acquisition

2 July 2003 Telecoms, Datacoms, Wireless, IoT

A developer of self-organising wireless sensor networks has launched the latest version of its ultra-small, ultra-low power wireless sensor networking device. Millennium Net's new i-Bean 5000, its latest coin cell transceiver, leverages a portfolio of radio technologies, including micro-power narrowband solutions, as well as wireless personal area network (WPAN) components.

According to the company, i-Bean-enabled sensors form self-organising wireless networks that enable the communication between sensors or other control devices without the need for human administration and with very low power consumption. Self-contained, miniature computers with a built-in power source, flash memory and peripheral devices, the i-Beans include a digital I/O interface, A/D converter and an RF transceiver for two-way communication. They also contain a serial interface enabling easy connection to existing sensors with RS232 interfaces.

Millenium Net says they can operate 10 years on a coin cell battery with a update of once per second. The IEEE802.15.4 standard defines the physical layer for short-distance wireless networks - in this case 115 Kbps over 30 m - with Millennium defining the protocol. Small repeaters can extend the network to hundreds of metres.
