Wireless LANs (WLANs) are being more and more widely deployed at present. They are a key element in dynamic business environments where permanent access to network resources is vital. They also provide a perfect solution for the creation of ad-hoc networks in emergency conditions within areas where dense wireless networks are in place. Voice over IP (VoIP) is a form of voice communication that uses data networks to transmit voice signals. The signal is appropriately encoded at one end of the communication channel, sent as packets through the data network, then decoded at the receiving end and transformed back into a voice signal.
