Satellite Internet

Satellite Internet is regarded as a network of networks that uses satellites to interconnect the various segments of the network so as to enable communication between devices present at distant locations. Through satellite internet nationwide coverage can be obtained. Basically, there is no physical structure of the internet on its own rather, it uses satellite …

Satellite Networks

Satellite Networks are defined as the orientation of various elements that establish communication through various nodes from one point of the earth to another point. Any satellite network can provide both types of transmission technologies i.e., point to point as well as broadcasting connections. When we talk about a network through which data is transmitted …

Satellite Communication

Satellite Communication is defined as a type of communication where the exchange of information takes place between different stations present on the surface of the earth using artificial satellites in space. And this communication occurs within the electromagnetic spectrum. So, in simplest terms we can say when communication between two or more ground-based units is …

Radio Wave Propagation

Radio Wave Propagation deals with the behaviour of radio waves when the waves travel from one end to another. It is sometimes known as simply wave propagation or propagation of electromagnetic waves. Radio wave transmission is a quite prominent method by which information can be transferred from one end to another. Radio wave propagation is …

CSMA with Collision Detection

CSMA/CD is an acronym used for Carrier Sense Multiple Access with Collision Detection and is a collision detection protocol. It is basically a refinement/improvisation of CSMA where the user detects the occurrence of data packet collision along with sensing for the availability of carrier in a multiple user network channel. This technique enables us to …

Carrier Sense Multiple Access (CSMA)

CSMA an acronym used for Carrier Sense Multiple Access. It is a type of random-access protocol, where multiple stations transmit their data over a shared channel. However, before transmission, each station senses the channel first and transmits only when finds the channel idle. In CSMA, each station is equally prioritized and thus the transmission occurs …

Hamming Codes

Hamming Codes are linear block codes designed to detect and correct errors introduced in message bits transmitted from an end to another through a communication channel. These are single error-correcting codes that offer ease in encoding and decoding. Hamming Code falls under the category of error correction coding and is a type of cyclic code. …

Cyclic Code

Cyclic Code is known to be a subclass of linear block codes where cyclic shift in the bits of the codeword results in another codeword. It is quite important as it offers easy implementation and thus finds applications in various systems. Cyclic codes are widely used in satellite communication as the information sent digitally is …

ALOHA Protocol

ALOHA Protocol is a type of random-access protocol that allows simultaneous transmission of data frames by multiple stations over a common communication channel. This protocol is a simple communication technique where each individual station that is a part of the network holds equal priority and operates independently. Some other names for ALOHA protocol are ALOHA system …
