Abstract
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.
