Common types of enterprise network connections

Most enterprise networks consist of LAN, WAN, and the Internet edge – potentially a data center. These engineering sectors include many options for interconnecting various network components and transmitting data to all parts of an enterprise network.

Here is a look at some of the most common types of network connections used in the Internet, LAN, and WAN sectors.

Internet Edge Connections

The Internet’s edge is the dividing point that separates a company’s private network from the public Internet. Communication within this part of an enterprise network is often referred to as Internet wide wave.

Depending on the physical location, available ISP options, and business requirements, common Internet edge connection options include:

  • twisted pair
  • cable
  • the basic
  • wireless

twisted pair

twisted pair internet connections They are often delivered as standard Cat6 cable or higher eight-pin braided cable. Other options include DSL or Integrated Services Digital Network, which uses traditional telephone cables that switch to an RJ-45 port via a DSL or ISDN modem. Throughput rates for twisted pair connections from ISPs often reach 1 Gbps.


Cable companies often provide broadband access to the Internet via coaxial cable. Like DSL and ISDN, cable modems switch the coax connection to the RJ-45 port at the customer’s port of call. Cable data service interface specification, or DOCSISthe technology behind cable broadband has increased steadily over the years, to the point that speeds can reach up to 2 Gbps.

the basic

Fiber is often used as a means of transportation for large companies that require higher Internet broadband throughput than twisted pair cables or coaxial cables can offer. Using optical fibers, broadband Internet services can reach 10 Gbps or higher.


Some Wireless broadband Options are used as primary or secondary backup connections at the edge of the Internet. In most cases, companies will choose a wired connection to access the Internet because wired is usually more reliable and less prone to drops or interference. However, in some situations, a wireless connection may be the only option for business.

Point-to-point Wi-Fi, public LTE or 5G, and satellite broadband are popular ways to connect a remote business or office to the Internet with relative ease. Keep in mind that wireless data transfer rates are much lower compared to wired alternatives. Expect throughput rates to be well below 100Mbps.

LAN connections and data center

Ethernet and Wireless options They are the predominant types of network connections for local area networks.


From an Ethernet perspective, twisted pair optical fiber cables connect, endpoints, and uplinks. Twisted pairs, fiber, direct-connected cable, and fiber channel remain popular options in private data centers. Each connection type varies based on the types of devices connected, the amount of transfer required, and the distances the connection needs to travel.


Wi-Fi is one of the most popular options for connecting to a wireless LAN, as all modern laptops, smartphones and tablets come fully integrated with Wi-Fi chips and antennas. The latest Wi-Fi 6 standard provides faster speeds and improved efficiency, Among other benefits.


Bluetooth Low Energy (BLE) is another form of wireless communication that is gaining traction in the local network. BLE has several use cases, including the dissemination of message notifications to remote workers and customers, as well as the real-time tracking of business-critical mobile equipment roaming throughout the facility.

Private 5G

companies started Express interest in private 5G networks Connection. Due to the recent availability of freely accessible spectrum in the Citizens Broadband Radio Service’s frequency band, companies can design and Deploy their 5G networks for private use.

Enterprises use private 5G in situations where Wi-Fi presents technical shortcomings that the private 5G network can overcome. Wi-Fi may be the best effort, while 5G private network can ensure improved performance and reduce access time.

wan اتصالات connections

The WAN portion of a company’s overall infrastructure is where a company’s LAN branches branch out and connect to various secondary sites or branch sites to create a single unified network that covers a large geographic area. Depending on the available connection options and required bandwidth, WAN connections are either acquired through a network carrier or privately deployed by the network owner.

WAN bus connection

Some types of network connections for WAN connection options that are leased through a carrier include:

  • MPLS
  • metro ethernet
  • leased lines
  • Synchronous optical network or synchronous digital hierarchy

In these cases, the carrier is responsible for the maintenance and ease of use of the communication between two or more locations. Some carriers may also offer wireless WAN connection services via point-to-point Wi-Fi, microwaveor LTE or 5G and a satellite delivery network.

Internet broadband is also commonly used in conjunction with point-to-point VPN connections to provide a logically created, encrypted tunnel between two or more business locations. Any type of Internet broadband can work, as long as it meets the necessary throughput and latency requirements.

Private WAN connection

Sometimes companies want to connect two or more buildings but don’t want to rely on a third party for WAN interconnection services. In these cases, dark fiber, microwave, and point-to-point Wi-Fi are options that allow for complete control and data protection while traversing WAN traffic.
