Satellite advantages
- Available worldwide
- Allows Internet access to remote, rural areas
Satellite disadvantages
-Very expensive for a fast connection
-Slow compared to fibre or 5G
Mobile communications advantages
- No cables needed
- Fast connection
Mobile communications disadvantages
-Not all devices can use 5G
-5G doesn’t travel as far, so more mobile towers are needed (which is expensive)
Social impacts of autonomous vehicles
- Loss of jobs to bus/lorry/taxi drivers
- Less accidents on the road and lives are saved
- the driver is able to complete other tasks
- Car sales will go down and the need for car salesmen and mechanics will reduce leading to a loss of employment.
Economic impacts on autonomous vehicles
-Haulage companies saving money as they won’t have to pay drivers.
-Less cars on the road and less accidents will mean more efficient journey
-More jobs created for programmers and people developing the technology.
Legal impacts on autonomous vehicles
