How does the work Network ? What is the Network ? :-

Satellite:-

1- Low Earth Orbit Electronics Height - 100 km - 1:30 hr Round Earth Work - Emerging Scan

2- Medium Earth orbit in 12 hours full earth rotation - Navigation

3- High Earth orbit Satalite A geosynchronous orbit is a high Earth orbit that allows satellites to match the Earth's rotation. Situated 22,236 miles (35,786 kilometers) above the Earth's equator, this position is a prime location for weather, communication and surveillance.

NETWORK:-

A network consists of two or more computers that are linked in order to share resources (such as 

printers and CDs), exchange files, or allow electronic communications. The computers on a network may be linked through cables, telephone lines, radio waves, satellites, or infrared light beams.

Two very common types of networks include.

1-Local Area Network (LAN):-A local area network (LAN) is a network that is limited to a relatively small area. It is usually limited to a geographic area such as a writing laboratory, school, or building.

2-Wide Area Network (WAN):-Wide area networks (WANs) connect networks in large geographic areas such as Florida, the United States, or the world. Dedicated transoceanic cabling or satellite uplink can be used to connect this type of global network.

Simply, "g" means "origin". While connected to the Internet, the connection speed depends on the signal strength that is shown on any mobile device in short form like 2G, 3G, 4G, 5G etc. Each generation of wireless broadband is defined as a set of telephone network standards that describe the technical implementation of the system.

The purpose of wireless communication is to provide high quality, reliable communication like wired communication and each new generation represents a big leap in that direction. Mobile communication has become more popular in the last few years due to rapid improvement in mobile technology.

GPS:-

Global Position System Launched -19-19-1980 (US) Air Force Launches Satellite Navigation Objective

People launched for the first time in 1995, fully in 2000.

2005-2015 (US) Airforce launched 50 GPS satellites.

How to work:-

GPS satellites are not destroyed in nuclear clock supplements for millions of years.

GPS satellite sent signal speed 50 bytes / minute

Your actual position is under 3 GPS satellites connected to you.

4 GPS satellites indicate connected sea level.

VPN:-Virtual Private Network

VOLTE:-Voice over lte

NFC:-Near field Communication.

4-5 Cm. easy use device pairing and mobile payment  

LiFi:-Light-fidelity. Starting Professor Harald Haas 2011 help of light communication achieve.

lifi:- based VLC concept
