Nothing to complain about, I can put the communicator on the midconsole or the passenger front seat and talk freely.
One factor seem to be the loudspeaker design, but I know from experience that it is just as much a question on all the DSP code who detects who is talking, who is listning, as well as some level of echo cancelling.
The real test to use two conference, speaker phones, "talking to each other", no problem yet.
To go more extreme one should hook up many speaker phones on a mutual conference. Compare most conference calls where he analysts are asked to use a regular phone, not a speaker or conference phone.
From some quick tests it seems Nokia has implemented some fairly robust algorithms on detecting both who speaks and who doesn't, as well as detecting too much feedback, maybe even some echo cancelling (although that usually doesn't work except when the sun shines)

P.S. I have always had fun with these great ideas on the perfect handsfree kits. |
