Abstract
This paper will provide a description of wireless topology which is a logical topology that depicts how computers connect as well as interact with each other without physical connection. Some of the wireless network topologies that this paper will focus on include; Point to Point topology which entails a link between two endpoints. Point to Multipoint network topology which is a one to many connections where multiple or various paths from one location open to multiple locations. The third one is multipoint to point topology which is many to one where multiple paths from multiple locations converge to a single location. Finally, the paper will also point out disadvantages of using each type of topology.
Point to Point Topology
This topology is considered the most common and simple type of connection which take place between two end points. Point to point topology is known to the basic models of convectional telephony and it can be set up dynamically and dropped when it is no longer needed using circuit switching or packet switching technologies (Santanu & Acharjya, 2013). In this case, some of the example of point to point topology includes; two computers communicating via modems, a mainframe terminal communicating with a front end processor and a work station communicating along a parallel cable to a printer or scanner, and therefore, the value of a permanent point-to-point network is unimpeded communications between the two endpoints.
Point to multi-point Topology
This type of topology is also known as one to many network topologies and it is where multiple paths from a single location open to multiple locations. Point to Multi-point connection is mostly used in telecommunications, IP telephony as well as wireless internet (Santanu & Acharjya, 2013). This topology enables private enterprises to establish connectivity to offices in most remote locations as well as provides long range non-physical backhaul solutions for various distinct sites. This topology uses IP telephony which employs the internet protocol packet switched connections in order to exchange fax, voice, as well as other variety of data that was previously carried over through public switched telephone network (PSTN).
For instance, according to Santanu & Acharjya (2013), “Point to Multipoint topology entails a central base station that has the capability of supporting other subscribers since it has a bridge known as the base station bridge or rather root bridge that provides a path where all data that passes between the wireless bridge clients initially go through.” This type of topology uses the same network resources from a single location that are shared among multiple stations. Furthermore, in a broadcast community, Point to Multipoint topology sends information from one uplink to multiple downlinks whereby in such type of setup, remote sites become limited to the receiver only mode so that there is only one transmission between the uplink as well as down link.
Besides, this type of topology incorporates a system that is designed as both single as well as bidirectional. The system entails central antenna or an array of many antennas that have the capability of broadcasting signal to several receiving antennas. The system in point to multi-point is topology is designed in a way that it makes use of a form of time division multiplexing that facilitates several users to share the same channel of frequency (Mehta & Yadav, 2014). For instance, since the signal is divided into different time slots, transmission of the signal is carried out in rapid success while using only apart of either of the channels capacity.
This type of topology can also be undertaken through bridging and this sis whereby one access point talks directly to other access points while every point serving as a another access point within the same network. On the other hand, According to Mehta & Yadav (2014), “Point to Multi-point link exists within this topology and it consists of central connection end point as well as multiple peripheral remotes and therefore, any data that is conveyed from the main point is received other peripheral remotes” however, any data that comes from peripheral remote is only received by the endpoint in the central connection but not by other peripheral remotes.
