5.7.5. Bluetooth intended use with respect to wireless emitters
The users of HD+ are trained nurses and physicians operating in hospitals, clinics and medical practices.
In these environment several devices (either medical or not) using various kind of wireless technologies
might be in use near an HD+ device operating in the same frequency range of HD+, such as other Bluetooth
devices or Wi-Fi devices.
Such devices implement a compatible channel division and are capable of detecting HD+ (and other BT
devices activities) as interference. Such devices employs techniques for changing their operating frequency.
Likewise, HD+ Bluetooth implementation is capable of dynamically negotiating the operating frequency
channel with the host and switch to the one with an optimal signal/noise ratio.
