IP Ingress Protection. An international classification system for
the sealing effectiveness of enclosures of electrical equipment
against the intrusion into the equipment of foreign bodies (i.e.
tools, dust, fingers) and moisture. This classification system
uses the letters "IP" followed by two or three digits. An "x" is
used for one of the digits if there is only one class of protection;
e.g. IPX4 which addresses moisture resistance only.
L
LAN Local Area Network. A computer network covering a limited
area, like a home, office, school or airport. The defining
characteristics of LANs, in contrast to wide-area networks
(WANs), include their usually higher data-transfer rates, smaller
geographic area, and lack of a need for leased
telecommunication lines.
LES Land Earth Station

they have a legitimate interest under the regulation.
