Example implementations relate to partitioning a radio into chains to scan channels. In some examples, a network device may comprise a processing resource and a memory resource storing machine-readable instructions to partition a default radio of the network device into a service chain and a scan chain in response to a scan request, scan a particular channel with the scan chain to discover devices operating on the particular channel of a network, and combine the service chain and the scan chain into the default radio.

A wireless network includes a tunable RF transmitter in wireless communication with a master node to transmit at a first slave frequency; a tunable RF receiver in wireless communication with the master node to receive at a second slave frequency; and an RF oscillator to communicate with the RF receiver and the RF transmitter an RF oscillator frequency to determine and tune the first and second slave frequencies. The RF oscillator is configured to receive calibration information including time information or frequency information, or both, from a reference node. The RF oscillator frequency of the RF oscillator is tuned based on the calibration information from the reference node to enable communication between the slave node and the master node at the tuned RF oscillator frequency.

A molecular clock which utilizes a rotational spectrum of gaseous molecules in a sub-THz region for clock stabilization is described. The molecular clock has a fast start-up characteristic and is also robust against mechanical vibration or variation of electromagnetic field. Also described is a chip-scale implementation of a molecular clock. In an embodiment, a molecular clock chipset only consumes a DC power of 66 mW. While providing a highly stable, compact and energy efficient time generator of portable devices.

Systems and methods for adjusting power and frequency based on three or more states are described. One of the methods includes receiving a pulsed signal having multiple states. The pulsed signal is received by multiple radio frequency (RF) generators. When the pulsed signal having a first state is received, an RF signal having a pre-set power level is generated by a first RF generator and an RF signal having a pre-set power level is generated by a second RF generator. Moreover, when the pulsed signal having a second state is received, RF signals having pre-set power levels are generated by the first and second RF generators. Furthermore, when the pulsed signal having a third state is received, RF signals having pre-set power levels are generated by the first and second RF generators.
