Math Response

The max speed of cable internet is 2Gbps, which is about 2000Mbps. How much slower, by PERCENTAGE is DSL? (you are going to take the max speed of DSL and divide it into the max speed of cable)

Features of DSL

• Features:

  • Typical speed is up to 30 Mbps (rarely up to 100 Mbps).

  • Latency is 20 ms up to 50 ms.

  • Most residential DSL is asymmetric (ADSL). That means downloading is faster than uploading. 

  • Businesses and freelance professionals who work with large files usually prefer symmetric DSL (SDSL), so downloading and uploading are equally fast.

  • DSL internet speeds depend on:

    • The quality of the wiring

    • How far you are from your local phone company’s exchange or hub

Multiple Choice

A fiber cable uses WHAT to transmit data.

• light signals
• magnetic fields
• radio waves
• electrical signals

Fiber features

• Fiber optic cable (uses light to carry information); it’s made up of several components:

• A core 

  • Usually made of ultra-pure glass or plastic

  • Transmits the information

  • Signals can travel at up to 70% of the speed of light 

• Cladding

  • Reflects light back into the core 

  • Keeps the signals within the core

• Buffer coating 

  • Protects the core and cladding from damage

  • Adds mechanical strength

• Strengthening fibers 

  • Protect the cable from pulling, bending, and crushing

• Cable jacket

  • Color-coded for identification

  • Protects against environmental factors

    • Moisture, abrasion, and chemicals

• Non-standardized connectors

  • No single connector type used across all applications

  • Commonly used ones are:

    • Subscriber connector (SC)

    • Local connector (LC), push-pull design

    • Small form pluggable (SFC)

Multiple Select

A fiber cable is made up of these components:

• copper

• core

• cladding

• buffer coating

Multiple Choice

What is FTTC?

• Fiber to the Curb(FTTC) is a broadband technology that combines fiber optic and copper cables.

• Fiber to the Node (FTTN) is a type of satellite internet.
• Fiber to the Core (FTTC) is a wireless technology.
• Fiber to the Home (FTTH) uses only copper cables.

Wireless (cellular) features

• Features:

  • Sends signals over cellular radio waves.

Which type of ISP would you recommend
for her and why? 

Satellite features

• Features:

  • Data is transmitted to and from a satellite orbiting earth.

• Speed tends to be on the low side:

  • Download speeds up to 250 Mbps

  • Upload speeds usually 3 Mbps

• Latency is usually more than 100 ms.

• Relies on a satellite dish. The satellite company can help you find the best location for your dish.

• Data caps may limit how much data you can use.

• Bad weather can affect your signal.

Multiple Choice

For satellite, why is the upload speed so low and the latency so high?

• The upload speed is high due to advanced technology and the latency is low because of short distances.
• The upload speed is low because of outdated equipment and latency is high due to interference from weather conditions.
• Upload speed is high because satellites are close to Earth and latency is minimal due to direct connections.
• The upload speed is low due to limited bandwidth and the latency is high because of the long distance signals must travel to and from the satellite.

Multiple Choice

When would satellite internet be the best option?

• When users live in urban areas with strong Wi-Fi signals.
• When satellite dishes are too expensive to install.
• When traditional broadband options are unavailable, especially in rural or remote areas.
• When high-speed fiber optic connections are available.

Fixed wireless features

• Features:

  • Data is transmitted via radio waves.

• Speed tends to be on the low side:

  • Download speeds up to 30 Mbps

  • Upload speeds usually 1 Mbps

• Latency is up to 60 ms.

• Relies on an antenna. A cable runs from the antenna to the router.

• The antenna works in all weather (storms, snow, etc.)

• The antenna must be within 10 miles of a cell tower with nothing blocking the line of sight.

  • No buildings, trees, etc.

• The cost tends to be higher than other broadbands.
