Single frequency systems save on power and latency. In multi-frequency systems when searching for devices you need to search in time and frequency domains. Using a single frequency system reduces the duration of the search as the device only needs to search in the time domain. As searching is typically the most power-intensive operation, reducing search time also reduces power consumption. Using a simple frequency system also reduces the implementationâ??s complexity. From a practical perspective, single frequency systems have been shown to perform very well on Personal Area Networks.
