— bluetooth support in speakerphones is usually provided as an addition to the wired USB interface. Bluetooth is convenient not only because of the absence of wires but also because such modules are installed in almost all modern smartphones, laptops and tablets, as well as in many PCs — so that speakerphones can be connected to such devices directly, without additional equipment (and for PCs without Bluetooth you can use a separate adapter). The range of such communication is about 10 m, it can be used not only for voice communication itself but also for other purposes — see the help about the A2DP and AVRCP profiles in the "Features" list.
