Wireless Topology

Wireless Topology

A computer network that is using Radio Frequency (RF) to connect nodes in the computer network is called a wireless network. Wireless networks are mostly used in homes, public areas, and telecommunication networks. The IEEE 806.11 is the standard used for wireless architecture. For IEEE 806.11 new revisions are released frequently and the standard is constantly evolving. The IEEE 806.11a, 806.11b, 806.11g, 806.11n, and 806.11ac is the latest revision to the standard (fortinet, n.d.). When considering the network topologies, Point-to-Point, Multipoint-to-Point, and Point-to-Multipoint are the most common types supporting wireless networking.

Point-to-Point Network Topology

Whenever two wireless nodes or devices need to transmit data to each other most suitable way of communication is a p2p network. Currently, the most used and common application for p2p communication is the way remote controls communicate with the controlled equipment. As an example, most p2p connections communicate using infrared waves. When considering the internet of things (IoT) also uses p2p communication where two nodes must frequently connect directly with one another without the involvement of third-party software. Bluetooth also uses a p2p mechanism by using radio wave signal-based wireless communication. So the advantages of this topology are easy to deploy and can deploy at a low cost.

Point to Multipoint Network Topology

Point to multipoint is the second most common network topology for wireless networks. Also, this methodology refers to a star topology. In this topology, one node behaves as the root node, and three or more devices can interact simultaneously. Further, all the devices in the point-to-multipoint network are communicated to the core device via the p2p topology. Central devices can be connected in the topology of a hierarchical star (Ref). More importantly, it is required to split up the data transfer channel between devices in point-to-multipoint (studycorgi, 2021). Not like the p2p, in point-to-multipoint, the addresses should be defined, and the way of accessing the channel should be pre-defined When considering the usage of this topology mostly used in cellular networks. The major advantage of this topology is reliable and fast, not only those faulty nodes could be identified easily (Sharma, Verma, & Sharma, 2014).

Multi-point to Point Network Topology

Multi-point to Point Network is the usual network topology for wireless local area networks (WLAN). The Multi-point to Point topology used frequency division multiplexing (FDM) (V, 2019). defined FDM to effectively manage bandwidth through non-overlapping frequency bands. In lots of scenarios in this topology, end users or nodes try to communicate with a wireless access point (WAP) over a shared frequency bandwidth and the end node has to compete with each other in order to communicate with the WAP. This topology highly suggests a wireless network in an area of less than 2500 square feet, such as in a house or small building (Khokhar, 2019). The main advantage of this topology is that even if one node is down it will not affect other nodes.


The major disadvantage of this topology is slow communication and only one device can communicate at a time. From a security perspective also p2p is bad topology because without knowing the target device source device can send malicious objects.The main disadvantage of this typology can be concluded from the fact that this network depends greatly on the central switch (Soparia & Bhatt, 2014). When the central unit malfunctions or fails, the entire network stops working. The main disadvantage of this typology is that makes sure the security of the network is very challenging and the way multipoint-to-point topology works make a bottleneck in the network traffic. Furthermore, if the core device gets infected or is vulnerable to attacks, the whole network can be disabled.


When considering above discussed wireless network topologies, each topology serves a different purpose. Even though point-to-point network topology is very old still it is used in IoT devices, Bluetooth, and remote controllers. Further when considering a small area network most suitable topology is multipoint-to-point topology and for a big wide area network such as telecommunication used multipoint-to-point.
