What is Point to Point topology?

In this type of network topology, a link provides a common link between two devices. The whole bandwidth of the link is possessed for transportation between specific two devices. A point-to-point network topology would be selected when the wires or cables to connect both ends (only two ends).

Point to Point topology definition is that, it is most simple topology than the other types. The network contains a straight link between two devices. Because of the direct connection, it is faster and more reliable than other types of connections. The disadvantage is that it can only be used in small areas close to the computer.

A point-to-point network contain two hosts, such as a computer, switch, or router, and servers connected back-to-back using a single cable. Generally, the receiving end of one host is connected to the sending end of another host, and vice versa.

Data transmission in a point-to-point topology can take place in multiple ways over the network: simplex, full-duplex, or half-duplex.

  • In simplex communication mode, signals flow in one direction, and only one node sends, and the other node receives.
  • In the half-duplex, each node can send and receive but cannot send and receive at the same time.
  • Two devices send and receive at the same time in full-duplex.


It is the most simple topology, easy to install and maintain and is designed for tiny networks. This kind of network has the chief disadvantage that it can only manipulate two connections in the system.

Metcalfe’s Law

This topology provides a permanent link between two endpoints. Switched point-to-point topology is the basic model of traditional phones. The value of a stable peer-to-peer network lies in the smooth communication between the two endpoints. The advantage of an on-demand point-to-point joint is directly proportional to the number of possible subscriber pairs and has been stated as Metcalfe’s Law.

Quiz: A point-to-point topology is typically used for WAN connections or wireless bridges.

Answer: True

Point to point topology Advantages and Disadvantages


  1. It provides low latency.
  2. Easy to handle and maintain.
  3. Node replacement in seconds.
  4. The connection is straightforward.
  5. No network operating system required.
  6. Highest bandwidth because only two nodes have the full bandwidth of the link.
  7. No particular network technician is needed, as each user can set their permissions.
  8. No need for expensive servers because a single workstation is used to access files.
  9. Related to other network topology, it is very fast because it can only locate two nodes.


  1. You cannot centrally back up files and folders.
  2. The notable common downside is that it can only be used in a small distance near the computer.
  3. If the link goes down, the entire network will fail, and the whole system depends on the shared channel.
  4. Another major disadvantage of this topology is that if only two nodes stop working, data cannot be transferred across the network.
  5. There is no security other than permission. Users typically do not want to log on to their workstations.

Point to Point topology example: A typical example of this point-to-point topology is a PC connected to a printer.

Point to point Wireless Topology

The point-to-point wireless topology (P2P) is the most straightforward network structure which you can place up to attach two locations utilizing a wireless connection. A point-to-point wireless connection can be performed from a short distance linking two areas that are only a few hundred meters away to a remote point-to-point wireless link that distances the two regions by tens of miles. In a point-to-point wireless connection, distance is affected by the height of each Ethernet radio, the frequency used, the power level, and environmental interference.

Point-to-point wireless connections are constructed between two points that manage a clear line of sight (LOS) within each other to increase the performance of the wireless connection. For point-to-point wireless links operating in a 5 GHz unlicensed band or a 4.9 GHz public safety band, we recommend using the connection in a clear line of sight Because above 2.4 GHz, line-of-sight (LOS) operation provides the more stable wireless connection.

Point-to-point wireless links operating at frequencies about 900 MHz or in the UHF band (400 MHz) can operate reliably in near-sight (NLOS) or non-line-of-sight conditions (NLOS point-to-point wireless links).


Point-to-point wireless links are commonly used in telecommunications, security, and network applications.
