An apparatus comprising: one or more processors; and memory storing executable instructions that, when executed by the one or more processors, cause the apparatus to: detect a first pilot signal included in a first ultrasonic beacon transmission, the first ultrasonic beacon transmission further including a first encoded information signal; decode, based on the first pilot signal, the first encoded information signal to identify a first medical system associated with the first ultrasonic beacon transmission; enter, based on the decoding of the first encoded information signal, into a first pairing state in which the apparatus is communicatively paired with the first medical system; detect, while operating in the first pairing state and within a threshold time of entering the first pairing state, a second pilot signal included in a second ultrasonic beacon transmission, the second ultrasonic beacon transmission further including a second encoded information signal; and continue, based on the detection of the second pilot signal within the threshold time, operating in the first pairing state without decoding the second encoded information signal. one or more processors; and memory storing executable instructions that, when executed by the one or more processors, cause the apparatus to: detect a first pilot signal included in a first ultrasonic beacon transmission, the first ultrasonic beacon transmission further including a first encoded information signal; decode, based on the first pilot signal, the first encoded information signal to identify a first medical system associated with the first ultrasonic beacon transmission; enter, based on the decoding of the first encoded information signal, into a first pairing state in which the apparatus is communicatively paired with the first medical system; detect, while operating in the first pairing state and within a threshold time of entering the first pairing state, a second pilot signal included in a second ultrasonic beacon transmission, the second ultrasonic beacon transmission further including a second encoded information signal; and continue, based on the detection of the second pilot signal within the threshold time, operating in the first pairing state without decoding the second encoded information signal. detect a first pilot signal included in a first ultrasonic beacon transmission, the first ultrasonic beacon transmission further including a first encoded information signal; decode, based on the first pilot signal, the first encoded information signal to identify a first medical system associated with the first ultrasonic beacon transmission; enter, based on the decoding of the first encoded information signal, into a first pairing state in which the apparatus is communicatively paired with the first medical system; detect, while operating in the first pairing state and within a threshold time of entering the first pairing state, a second pilot signal included in a second ultrasonic beacon transmission, the second ultrasonic beacon transmission further including a second encoded information signal; and continue, based on the detection of the second pilot signal within the threshold time, operating in the first pairing state without decoding the second encoded information signal.
