Study Notes

Internet Connection Options

Most common internet connection options for homes and small businesses include cable, DSL, fiber, satellite, cellular and Wireless Internet Service Providers (WISPs).
Download speed is how fast data is retrieved, upload speed is how fast data is sent.
Download speed in megabytes per second (MB/s) is calculated by dividing the internet speed in megabits per second (Mbps) by 8.

Cable Internet

Uses existing coaxial cable infrastructure.
Speeds vary greatly depending on the area.
Offers high download speeds but slower upload speeds.
Bandwidth is shared by users in the area, leading to potential slowdown during peak hours.

Digital Subscriber Line (DSL)

Uses existing phone lines to provide high-speed internet.
Uses multiplexing technique to create two channels: one for phone communications and one for DSL communication.
Requires special DSL filters to block DSL signal from phone line.
Asymmetric DSL (ADSL) provides fast download speeds but slow upload speeds.
Symmetric DSL (SDSL) provides equal upload and download speeds but is more expensive.
Speeds typically max out at 100 Mbps and are affected by distance from the main hub.
DSL is not shared with other users in the area.

Fiber Internet

Uses fiber optic cables to transfer data using light.
Offers symmetrical upload and download speeds.
Results in lower latency and improved performance for media streaming, gaming and file downloads.
Requires new infrastructure, not available in many areas.

Satellite Internet

Connects to the internet via orbiting satellites.
Requires a clear line of sight to the sky, making it ideal for remote locations.
Provides reasonably fast download speeds but slow upload speeds.
Experiences high latency due to the distance involved in data transmission.
Not ideal for time-sensitive applications like gaming, voice data or video calls.
Usually has a monthly data cap.

Cellular Internet

Uses existing cellular infrastructure.
Can be accessed via adapters like USB adapters or mobile hotspots.
Offers good download speeds but slow upload speeds.
Latency and environmental interference are potential issues.
Provides mobility as it is accessible in areas with phone service.

Wireless Internet Service Provider (WISP)

Provides wireless connectivity, often used in rural areas where wired internet is not readily available.
Uses a wireless mesh network operating on open radio bands.
Uses a fiber backbone in a central location to connect to a large antenna.
Smaller antennas are installed to extend coverage.
Users receive a satellite or antenna connected to their buildings.
Speeds are typically lower than wired connections, ranging from 25 to 100 Mbps.

Summary

This lesson covered various residential and small business internet connection options.
Cable internet, DSL and Fiber internet are wired connection choices.
Satellite internet, cellular internet and WISP cater to areas without wired connections.
Wired internet offers faster speeds while wireless options have latency issues and require specific equipment.
