How satellite Communications work. Satellite communication systems work through a series of steps involving the transmission of signals between ground-based stations and satellites in orbit. Here’s a simplified explanation: The entire process enables communication over long distances, providing a global reach without the need for a physical infrastructure connecting the communicating parties. It’s important to …
Satellite System Use. Satellite communication systems are used in various applications where traditional land-based communication infrastructure may be impractical or unavailable. Here are some key areas where satellite communication systems are commonly employed: In essence, satellite communication systems are versatile and serve as a critical infrastructure component in situations where other forms of communication may …
Satellite communications involve a complex architecture that allows for the transmission of data, voice, and video signals between ground-based stations and satellites in orbit. Here’s a simplified breakdown: Satellite Communications architecture allows for global communication coverage, making it possible for users to communicate over long distances without the need for a physical connection between them.
WiMAX, short for Worldwide Interoperability for Microwave Access, is a wireless communication standard that provides high-speed broadband connectivity over long distances. It is based on the IEEE 802.16 family of standards and is designed to deliver wireless metropolitan area network (MAN) and wide-area network (WAN) connectivity. Here are key features and aspects of the standard: …
What is WIFI Wi-Fi, short for Wireless Fidelity, is a technology that enables wireless local area networking (WLAN) based on the IEEE 802.11 family of standards. Wi-Fi allows devices such as computers, smartphones, tablets, and other wireless-enabled devices to connect to the internet and communicate with one another within a local network without the need …
Cellular networks, including GSM (Global System for Mobile Communications) and UMTS (Universal Mobile Telecommunications System), are mobile communication technologies that enable wireless communication between mobile devices and provide voice and data services. 1. GSM (Global System for Mobile Communications): 2. UMTS (Universal Mobile Telecommunications System): Key Features Common to Both GSM and UMTS: UMTS, being …
CSMA/CA stands for Carrier Sense Multiple Access with Collision Avoidance. It is a network protocol used in wireless communication to avoid collisions in the transmission of data. Here’s a breakdown of how CSMA/CA works: In CSMA/CA, a device wishing to transmit data follows a procedure: This process helps in avoiding collisions by ensuring that the …
Code Division Multiple Access (CDMA) is a digital cellular technology that allows multiple users to share the same frequency band simultaneously. Unlike Time Division Multiple Access (TDMA) or Frequency Division Multiple Access (FDMA), which divide the frequency band into time slots or channels, CDMA uses a spread spectrum technique. In CDMA, each user is assigned …
Quadrature Phase Shift Keying (QPSK) is a digital modulation scheme that represents two bits of data per symbol. In QPSK, four different phase shifts of the carrier signal are used to encode the binary data. Each phase shift corresponds to a specific combination of two bits (00, 01, 10, and 11). The term “quadrature” refers …
Quadrature Amplitude Modulation (QAM) is a modulation scheme used in digital communication to transmit data by varying both the amplitude and phase of a carrier signal. QAM allows for the transmission of multiple bits of information per symbol, making it a more bandwidth-efficient modulation scheme. In QAM, the amplitude and phase of the carrier signal …
