In this modern era, Wireless communication have become an integral part of each other to provide wireless communication to common man that helps people located in any part of the world communicate easily. Wireless communication technology transmits information over the air using electromagnetic waves like IR (Infrared), RF (Radio Frequency), satellite, etc. For example, GPS, Wi-Fi, satellite television, wireless computer parts, wireless phones that include 3G and 4G networks, and Bluetooth.  This white paper summarizes the importance of Wireless and Telecommunication, their advantages and disadvantages.

A communications satellite is an artificial satellite that relays and amplifies radio telecommunications signals via a transponder, it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications. There are over 2,000 communications satellites in Earth’s orbit, used by both private and government organizations.

Aerospace is the human effort in science, engineering, and business to fly in the atmosphere of Earth (aeronautics) and surrounding space (astronautics). Aerospace Engineering and Technology focusing on communications between earth communication stations and space-based communication satellites. The method involves designing Communication satellites, Space Missions, Space Applications, Space Propulsion, designing and building earth stations, Satellite Launcher Technology, repairing and installing satellite communication equipment.

Artificial Intelligence is a field of study of computer science based on the premise that intelligent thought can be regarded as a form of computation one that can be formalized and ultimately mechanized. AI algorithms can tackle learning, perception, problem-solving, language-understanding and/or logical reasoning. In the modern world, AI can be used in many ways even when it is to control robots. Sensors, actuators and non-AI programming are parts of a larger robotic system.

For many of us, when we send a text or make a call from our cell phones, we're relying on 4G. Though for as much as we rely on it, very few of us know what it actually means. In reality, the "G" in these terms only stands for generation: generation of wireless mobile telecommunications technology. "5G moves us to a truly connected society with very high data rates, low latency, and massively interconnected devices".  5G is generally seen as the fifth generation cellular network technology that provides broadband access. The industry association 3GPP defines any system using "5G NR" (5G New Radio) software as "5G", a definition that came into general use by late 2018. 

Communication is the production and exchange of information and meaning by use of signs and symbols. It involves encoding and sending messages, receiving and decoding them, and synthesizing information and meaning. Communication permeates all levels of human experience and it is central to understanding human behavior and to nearly all public health efforts aimed at fostering health behavior change among individuals, populations, organizations, communities, and societies.

3D printing is an awesome merging of futuristic fields. From Mars dust buildings to mini satellites, these are our most promising 3D printing in space projects.  In aerospace many applications, challenges, innovations related to 3D printing are tuning pace at a higher rate. Step by step, researchers are looking for different applications to this cutting-edge technology in space whereas additive manufacturing is challenging and requires new technologies and resistant materials. With the two different axis of applications arises variant benefits i.e. 3D printing inside of the station and 3D printing outside of the station. Inside it will play role significantly in their daily life in orbits during space exploration.

An Antenna is a specialized transducer that converts radio-frequency (RF) fields into alternating current (AC) or vice-versa. There are two basic types: the receiving antenna, which intercepts RF energy and delivers AC to electronic equipment, and the transmitting antenna, which is fed with AC from electronic equipment and generates an RF field.

Mobile Software and Services is the technology used in cellular communication. Mobile code-division multiple access (CDMA) technology has evolved rapidly over the past few years. Since the start of this millennium, a standard mobile device has gone from being no more than a simple two-way pager to being a mobile phone, GPS navigation device, IoT , an embedded web browser and instant messaging client, and a handheld gaming console. Many experts believe that the future of computer technology rests in mobile computing with wireless networking.

Green communications is the practice of selecting energy-efficient communications and networking technologies and products, and minimizing resource use whenever possible in all branches of communications. Green communication technologies primarily developed for addressing the environmental impact of traditional communication systems and networks. It reduces resource to use whenever possible in all categories of communications.

Mobile satellite communication refers to networks of communications satellites intended for use with mobile and portable wireless telephones. The channel characterization of a mobile satellite communication which is an important and fast growing arm of wireless communication plays an important role in the transmission of information through a propagation medium from the transmitter to the receiver with minimum barest error rate putting into consideration the channel impairments of different geographical locations like urban, suburban, rural and hilly.
