The Ultra Low-Power WiseNET System
The WiseNET system includes an ultra low-power System-on-Chip (SoC) hardware platform and WiseMAC, a low power Medium Access Control protocol (MAC) dedicated to duty-cycled radios. Both elements have been designed to meet the specific requirements of wireless sensor networks and are particularly well suited to ad-hoc and hybrid networks. The WiseNET radio offers dual-band operation (434-MHz and 868-MHz) and runs from a single 1.5-V battery. It consumes only 2.5-mW in receive mode with a sensitivity smaller than 108-dBm at a BER of 10-3 and for a 100-kb/s data rate. In addition to this low-power radio, the WiseNET System-on-Chip (SoC) also includes all the functions required for data acquisition, processing and storage of the information provided by the sensors.
