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.
