Wireless communication is the transfer of information over a distance without any physical media or cables, usually through electromagnetic radiation. While wireless networking can be used for a variety of purposes, there are three primary configuration topologies that are most commonly used: point to point (P2P), point to multipoint (PMP) and multi-point to point (MP2P).
Point-to-Point (P2P): Point-to-point configurations involve two points in direct interaction with each other. In this setup, one device transmits data while the second receives it. This type of network is typically seen between two computers connected on a local area network or in an ad hoc connection like Bluetooth. One scenario where P2P could come into play is allowing two people hundreds of miles away from each other to stream data back and forth such as video conferencing or file sharing. This type of network allows for low latency due to the close geographic proximity between the devices which makes it ideal for streaming media services like Netflix or YouTube. One downside of using this topology is its reliance on line of sight; if there’s anything obstructing either device’s view then communication will be disrupted until the obstruction has been removed.
Define each topology, provide a scenario for using each topology, and identify at least one disadvantage of using each topology.
Point-to-Multipoint(PMP): Point-to-multipoint networks offer some advantages over P2Ps since they allow multiple users within the same range to access data from a single source instead having separate individual connections with every user in range.. An example would be someone streaming content from their home computer over WiFI; everyone within their house can access that content at once rather than them needing separate connections for each person accessing it individually. The main disadvantage here comes down again to line of sight interference; if someone moves out of range then they become unable to receive data until they move back into range again, whereas with something like cellular technology different towers can take up the slack when one falls out temporarily so no service disruption occurs.
Multi Point – To– Point(MP2P): Multi point –to–point networks consist primarily off multiple devices broadcasting signals at once across vast distances, similar how cell phone towers operate wherein anyone close enough within its vicinity can pick up those signals too—essentially acting as relays so others farther away have access too similarly how cell phone towers work wherein anyone close enough can pick up signals being broadcasted by them thereby extending their reach even further . A great example would be satellite television providers whereby all customers can access programming simultaneously regardless off their location relative too these satellites orbiting earth since multiple satellites are broadcasting signals simultaneously thereby ensuring uninterrupted service . However , weak signal strength caused by obstacles like walls , trees , etc might cause disruptions and degrade quality depending on how far away people live from these transmitters .
