Why is the Internet slower in Vanuatu?
Internet Infrastructure• Fibreoptic networks use light pulses to
transmit data (literally at the speed of light)• Cost• Geographical location
• Vanuatu relies on satellite connections for all communications
• Satellite signals have to travel a great distance above the earth and then back again causing a delay in data transmission
