A Local Area Network (LAN) is a data communication network that interconnect various terminals or computers within a building or limited geographical area. There are various types of LAN technologies used. They support wired and wireless communications such as Fast Ethernet, Token Ring, ARCNET support and FDDI are frequently used across the globe. Letu2019s learn about various LAN technologies here.

LAN Technology A Local Area Network (LAN) is a data communication network that interconnect various terminals or computers within a building or limited geographical area. The connection among the devices could be wired or wireless. Computers and various digital technologies are connected in network to exchange information. These LANs are driven by different technologies to initiate a connection between different devices. Let’s learn more about common LAN technologies, types of LAN technologies used today.
Important Types of LAN Technologies • LAN technologies support both wired and wireless connections. It is widely used across the globe. The following are popular types of LAN technologies: • Ethernet • Power Over Ethernet
Ethernet Ethernet technologies are popular among all other LAN technologies covered under IEEE standards 802.3. Its simplicity, low-cost investment, backward compatibility, and noise resistance make it a popular choice over others. Ethernet works on Layer 1 and Layer 2 switches. Ethernet technology has evolved over the years. It is distinguished based on their speeds. .
1993s 1995s 1998s 2002s It is also referred to as 10Base5. It is designed to carry 100 Mbit/s. It is designed to carry 1 gigabit or 1 billion bits per second. It is designed to transfer 10 Gbits/seconds. Ethernet Technology Evolution 10 Mbit/s Fast Ethernet Gigabit Ethernet 10 Gigabit Ethernet
10 MBIT/S It is the first iteration of this technology, which was introduced in 1983. It is referred as 10Base5. Ethernet Evolution FAST ETHERNET It is designed to carry 100 Mbit/s. Fast Ethernet is covered under the IEEE 802.3u standard. 100Base-TX is the most popular type of Ethernet physical layer of the Fast Ethernet. Here 100 refers to the signal-carrying medium, which can be a Twisted Pair Cable or a Fiber Optic Cable. However, the last character X or 4 refers to the signal code. The X is a placeholder for TX and FX.
GIGABIT ETHERNET It is designed to carry 1 gigabit or 1 billion bits per second. It is defined under IEEE 802.3ab standard. It replaced fast ethernet for increasing speed requirement of Voice over IP(VoIP) and multimedia network.1000BASE-T is the most popular version of Gigabit Ethernet. Ethernet Evolution 10 GIGABIT ETHERNET It is one of the most recent Ethernet standards, 10 Gigabit Ethernet is designed to transfer 10 Gbits/seconds, which makes it faster than Gigabit Ethernet. It uses fiber optic cables.
Power Over Ethernet Power Over Ethernet can transmit electric power and data on the same cable. It is known as PoE. PoE used to connect devices such as Internet Protocol (IP) camera, and Voice over Internet Protocol (VoIP) phones. It makes use of Ethernet cable 5 or higher category. It doesn’t require any external AC cord or adapter. Due to this distinct feature, POE emerged as a popular Ethernet standard over the years. It used to connect various types of wireless Ethernet devices.
TOKEN RING Token Ring technology was developed by IBM. It uses three-byte frames to connect computers. These three-byte frames are known as tokens, and they travel along the servers or computer to form a logical ring. The token ring network has data transfer rates of 4, 16, and 100 Mbps. It is largely used in corporate environments, but nowadays getting replaced by Ethernet. Power Over Ethernet ASYNCHRONOUS TRANSFER MODE (ATM) Asynchronous Transfer Mode (ATM) is a fast communication technique. It is cell-based. This telecommunication standard is defined by ITU and ANSI. It is used for transferring various types of signals in the network. The key advantage of ATM is that it doesn’t require separate overlay networks for signal transmission. ATM can connect points in close and farther geographical locations.

As now the role played by each of these LAN technologies is well persuaded. It is important to use the right type of device for achieving the desired result. To get the best LAN Connectivity solution, we recommended to source technology devices from trusted manufacturer like Versitron. The company has been providing networking connectivity solution since 1958. Fiber optic network switches, Fiber optic media converters, fiber optic multiplex and so on.
