Study Notes
- Satellite internet connections can have latency from 250ms up to 40ms with Starlink, aiming for 20ms.
- Satellite connections operate in higher frequencies, like two gigahertz, and require line of sight. Rain can disrupt the connection due to rain fade.
- Fiber optic internet connections allow for high-speed communication over long distances but are expensive and require costly repairs.
- Fiber optics can now be extended to homes and businesses for improved bandwidth.
- Cable broadband uses the same cable for cable television to offer video, voice, and data communication.
- DOCSIS is the standard for sending data over cable networks, supporting very high speeds and enabling multiple streams of data.
- DSL uses existing telephone lines for high-speed internet connections, with asymmetric download and upload speeds.
- Cellular networks can provide internet connectivity using tethering or hotspots, with speeds limited by distance to the Central Office and network type.
- Wireless Internet Service Providers (WISPs) offer internet connections using local ground stations, often in rural areas or with limited infrastructure.
- WISPs can offer high-speed connections up to 1,000 megabits per second and may require external antennas for optimal performance.
