If these Bluetooth devices can start talking to each other automatically when they e in proximity, won the spectrum be overloaded in densely packed areas such as airports and conference halls?
Bluetooth communication is based upon proximity networking, and scenarios are possible in which Bluetooth devices could automatically establish communication when they come into proximity of each other. However, such operation needs to be explicitly enabled and is usually an application and often an end-user selection. As described in the specification, Bluetooth radios can be placed into generally discoverable mode, limited discoverable mode, or nondiscoverable mode. Generally discoverable mode allows a given device to be discovered (and thus, presumably, although not necessarily, to be connected to) by most any other Bluetooth device. Limited discoverable mode limits discovery only to certain other well-defined devices, and nondiscoverable mode makes the given device “invisible” to other devices. With the ability of the user to choose which of these modes is used and to determine which other devices he or she wants to connect to, the problem of all the devices in the vicinity attempt
