Voice over WiFi

Paper Summary:

This paper explains that VoIP is being replaced by 'Voice over WiFi', a technology that allows users to log on to the Net wirelessly, which is extremely useful for laptop users. The author points out that companies, such as Motorola, Japanese giant NEC, and Nokia have already begun or are planning to commercialize models that use WiFi technology both for data access and cellular voice. The paper relates that VoWiFi services are expected to consume much larger amounts of energy than their cellular counterparts, a problem that needs to be solved because customers will not be willing to use this service only for a few hours.

From the Paper:

"Voice over IP has its origins in 1995, when Vocaltec, Inc. released its Internet Phone Software that operated on the normal home PC of those times, with a 486 processor. Even so, VoIP had been discussed as a project for several years before that. The initial software designed encompassed the general idea used in the VoIP technology: the voice analogue signal were transformed into digital signals and where split in packages and sent as such over the Internet. The problem was that, for the technology to work, both the caller and the receiver needed the same type of equipment and the same software."
