Ethernet local area network layout floor plan

"The Ethernet physical layer is the physical layer component of the Ethernet family of computer network standards.
The Ethernet physical layer evolved over a considerable time span and encompasses quite a few physical media interfaces and several magnitudes of speed. The speed ranges from 1 Mbit/ s to 100 Gbit/ s, while the physical medium can range from bulky coaxial cable to twisted pair and optical fiber. In general, network protocol stack software will work similarly on all physical layers.
10-gigabit Ethernet was already used in both enterprise and carrier networks by 2007, with 40 Gbit/ s and 100 Gbit/ s Ethernet ratified. ...
Many Ethernet adapters and switch ports support multiple speeds, using autonegotiation to set the speed and duplex for the best values supported by both connected devices. If auto-negotiation fails, a multiple-speed device will sense the speed used by its partner, but will assume half-duplex. A 10/ 100 Ethernet port supports 10BASE-T and 100BASE-TX. A 10/ 100/ 1000 Ethernet port supports 10BASE-T, 100BASE-TX, and 1000BASE-T." [Ethernet physical layer. Wikipedia]

"There are two definitions for wireless LAN roaming:
Internal Roaming (1): The Mobile Station (MS) moves from one access point (AP) to another AP within a home network because the signal strength is too weak. An authentication server (RADIUS) performs the re-authentication of MS via 802.1x (e.g. with PEAP). The billing of QoS is in the home network. A Mobile Station roaming from one access point to another often interrupts the flow of data among the Mobile Station and an application connected to the network. The Mobile Station, for instance, periodically monitors the presence of alternative access points (ones that will provide a better connection). At some point, based on proprietary mechanisms, the Mobile Station decides to re-associate with an access point having a stronger wireless signal. The Mobile Station, however, may lose a connection with an access point before associating with another access point. In order to provide reliable connections with applications, the Mobile Station must generally include software that provides session persistence.
External Roaming (2): The MS (client) moves into a WLAN of another Wireless Internet Service Provider (WISP) and takes their services (Hotspot). The user can independently of his home network use another foreign network, if this is open for visitors. There must be special authentication and billing systems for mobile services in a foreign network." [Wireless LAN. Wikipedia]

"A local area network (LAN) is a computer network that interconnects computers in a limited area such as a home, school, computer laboratory, or office building using network media. The defining characteristics of LANs, in contrast to wide area networks (WANs), include their smaller geographic area, and non-inclusion of leased telecommunication lines. Ethernet over twisted pair cabling, and Wi-Fi are the two most common technology standards currently used to build LANs." [Local area network. Wikipedia]
