is a methodology and group of technologies for the delivery of voice
communications and multimedia sessions over Internet Protocol
(IP) networks, such as the Internet. The terms Internet telephony,
broadband telephony, and broadband phone service specifically
refer to the provisioning of communications services (voice, fax,
SMS, voice-messaging) over the public Internet, rather than via the
public switched telephone network (PSTN).
WLAN
A Wireless Local Area Network links devices via a wireless
distribution method (typically spread-spectrum or OFDM radio), and
usually provides a connection through an access point to the wider
internet. This gives users the mobility to move around within a local
coverage area and still be connected to the network.
WPAN
A Wireless Personal Area Network is a personal area network - a
network for interconnecting devices centered around an individual
person's workspace - in which the connections are wireless.
Typically, a wireless personal area network uses some technology
that permits communication within about 10 meters - in other
