Study Notes
Satellite Communication
- Common forms of satellite communication include Geostationary, Low Earth Orbit (LEO), and Mid-Earth Orbit (MEO) satellites.
- Infrared satellites are not a typical type used for satellite communication.
Communications Satellites
- The primary function is to act as relay stations, receiving signals from one Earth station and rebroadcasting them to another.
- They can also broadcast TV signals, monitor weather patterns, and provide GPS services.
Wireless Communication Standards
- GSM (Global System for Mobile Communications) is the best-known standard for 2G wireless communication.
- Long Term Evolution (LTE) is associated with 4G wireless communication.
5G Wireless Communications
- Expected to have higher data transmission rates, reduced power consumption, and increased reliability.
- 5G is anticipated to expand coverage compared to 4G, not limit it.
Modems and Network Devices
- A modem converts digital data into an analog signal for transmission over regular analog lines.
- Routers forward data packets across multiple networks, while gateways serve as entry points to other networks like the Internet.
- Front-end processors manage communication to and from computer systems for numerous users.
Software-Defined Networking (SDN)
- SDN is an emerging networking approach allowing programmable central control via a controller rather than relying solely on physical devices.
Business Analytics and Intelligence
