Abstract :
The impact of random frequency offsets on low-end sensor networks is considered. Results indicate that opening up receiver bandwidth not only helps improve throughput as measured in bits per second but can also result in improved bandwidth efficiency as measured in bits/sec/Hz. Implementing such a system will not only drive down node costs but also increase their operational lifetime.
