Study Notes
- Satellite networking provides internet connectivity by transmitting geneema01to a satellite in space and back to Earth
- Historically, satellite networking had high latency, with up to 500 milliseconds round trip, but new technologies aim to lower it to 20-40 milliseconds
- Satellite networking requires expensive equipment and can provide relatively good bandwidths, such as 50 Mbps download and 3 Mbps upload
- Starlink is a newer satellite networking service that is promising to increase speeds and make satellite networking more common
- Satellite networking is useful for remote sites or areas without other internet connectivity options
- Communication to satellites uses high frequencies, such as 2 GHz, but can be affected by rain showers, causing potential connectivity losses
- Copper connections, such as DSL or cable modem, are common for local and wide area internet connectivity, offering speeds ranging from 20 Mbps to 1 Gbps
- Copper connections have limitations in terms of distance and bandwidth, with DSL having about a 10,000 foot limitation and asymmetric speeds
- Cable modem uses coax connections and can provide high-speed internet, but depends on DOCSIS version for speed range
- Fiber optic connectivity offers high-speed, long-distance internet, but is more expensive and difficult to repair compared to copper networks
- Metro Ethernet is a high-speed connectivity option within a small geographic area, allowing for easy connection of multiple locations using Ethernet.
- Providers use wavelength-division multiplexing or SONET rings in their network to provide high-speed connectivity, but customers see a simple Ethernet connection.
Test your knowledge about satellite and copper networking, including technologies, speeds, and limitations. Learn about the use of satellite networking in remote areas and the characteristics of different copper connections like DSL, cable modem, and fiber optics.
