One cool feature of UMTS compared to GSM is that you can't hear the interaction with the network when the mobile device is close to a radio or telephone conference equipment. This is because while GSM transmits bursts whose transmit on/off changes can be picked up by such equipment, UMTS transmits continuously in the uplink direction and as a consequence no annoying clicking sounds can be heard. With the introduction of Continued Packet Connectivity (CPC), however, this will change to conserve power. So I am wondering if CPC devices will again produce some sort of a clicking noise in other audio equipment!? I hope not… And in case it does it would be nice if CPC could be deactivated in the device. I know, highly unlikely that such an option will be put into devices but then one never knows. If a 'sexy' name can be attached to it someone might just do it. How about 'stealth mode' or 'undisturbed meeting mode'. I am sure marketing departments can come up with something better.
