The radio receiver in the device is using the same
frequency and bandwidth as the transmitter.
Cables and transducers:
Cables and transducers are not used during normal use
of the device nor while programming the device.
Quality of Service for Wireless
Technology
Bluetooth® Low Energy (LE) wireless technology enables
communication between the generator and the patient
controller. The requirements for the quality of service
(QoS) vary depending on the use environment
(operating room, recovery room, and home
environment).
After the patient controller is paired with a generator,
the Bluetooth wireless technology symbol is visible on
the patient controller in the upper right-hand corner of
the screen. When the Bluetooth wireless connection is
not active, the symbol is grayed out.
The standard Bluetooth LE wireless technology data rate
is 1 Mbit/s. The quality of service (QoS) should allow
wireless data to be transferred at a net rate of 2.5 kB/
sec. Each connection interval includes a semi-duplex
transmission with a required acknowledge, a
transmission latency in each direction (2x), and a
receive-to-transmit mode (RX-to-TX) time. Data is resent
