1. An apparatus, comprising:
a memory for storing instructions;
a set of processing units to execute instructions for controlling a plurality of sensor nodes in a wireless network architecture and determining locations of the plurality of sensor nodes; and
a radio frequency ( ) circuitry to transmit communications to and receive communications from the plurality of sensor nodes each having a wireless device with a transmitter and a receiver to enable bi-directional communications with the radio frequency circuitry of the apparatus in the wireless network architecture, wherein the set of processing units of the apparatus are configured to execute instructions to:
calibrate an automatic gain control stage of the radio frequency circuitry by measuring a delay of the automatic gain control stage as a function of gain; and
determine a time of flight estimate for communications between the apparatus and a sensor node based on the calibration of the automatic gain control stage.
