What is Satellite?
Signal bounces off an orbiting satellite to a dish at your location
What is the speed and latency of the Satellite?
Speed = download 250 Mbps; upload 3 Mbps
Latency = High (250-350ms+) due to long distance
What is satellite best used for?
Remote or rural areas with no cable or DSL.
GPS, television, and radio.
What is point-to-multipoint in the context of satellite?
One satellite can provide a signal to a number of receivers simultaneously
What are the drawbacks of satellite?
Weather interference, data caps, high latency
How does Fibre (fibre-optic) work?
Transmits data as light pulses through glass/plastic cables
What speed and latency does Fibre have?
Speed = Up to 2 Gbps
Latency = very low
What is Fibre best used for?
High-bandwidth users: streaming, gaming, remote work, businesses
What are the drawbacks of Fibre?
Limited availability and high cost
How does Cable work?
Uses coaxial TV cable infrastructure
What speed and latency does cable have?
Speed = Download 100-1000 Mbps; upload typically lower
Latency = low to moderate
Where is cable best used?
Residential broadband in suburban and urban areas
What is the drawback of cable?
Speeds degrade during peak hours; shared bandwidth
What is DSL and how does it work?
Travels over existing copper telephone lines
What speed and latency does DSL have?
Speed = download 70 Mbps; upload 2O Mbps
Latency = moderate
What is DSL best used for?
Areas with phone lines but no cable or fibre
What is the key drawback of DSL?
Distance from the phone company affects speed and latency
How does cellular work?
Uses cellular network towers (4G LTE / 5G)
What is the speed and latency of cellular?
Speed: Up to 100 Mbps with 5G LTE; over 1 Gbps with mmWave
What is cellular best used for?
Mobile devices and areas lacking fixed broadband
what are the drawbacks of cellular?
Data caps, signal depends of tower proximity
What is WISP and how does it work?
Wireless Internet Service Provider
Fixed wireless - radio waves signal from tower to a fixed receiver (small dish or antenna)
What is the speed and latency of WISP?
Speed = 6 Mbps to 50 Mbps
Latency = Low to moderate
What WISP best used for?
Rural areas where cable and fibre are not available
