Detailed explanation-1: -Data emanation (or signal emanation) is the electromagnetic (EM) field generated by a network cable or network device, which can be manipulated to eavesdrop on conversations or to steal data. Data emanation is sometimes also referred to as eavesdropping, although this is not accurate.
Detailed explanation-2: -Electromagnetic interference (EMI) is unwanted noise or interference in an electrical path or circuit caused by an outside source. It is also known as radio frequency interference. EMI can cause electronics to operate poorly, malfunction or stop working completely. EMI can be caused by natural or human-made sources.
Detailed explanation-3: -Types of Wireless Network Connections In addition to a LAN, there are a few other types of common wireless networks: personal-area network (PAN), metropolitan-area network (MAN), and wide-area network (WAN).
