Connectivity Barriers

Built-in connectivity provides a robust solution

Page 12: Tc us and connectivity for automotive telematics

Connectivity Barriers

Brought-in connectivity is low-cost and the call costs are transferred to the user

Connectivity Barriers

Who is doing what? – embedded modem and SIM

Brought-in solution - Bluetooth HFP (data over voice)

Embedded (built-in) solutionCustomer pays for call costs

Connectivity Barriers

There is no single perfect connectivity solution

e.g. 1 e.g. 2

Low cost; user pays ongoing costs

Widely compatible solution

Low data rates are acceptable

Easy for customer to operate

Best communications performance

Conclusions

• Vehicle manufacturers need to make decisions on communications approach and data transfer method before finalising their TCU design.

• Built-in/embedded or brought-in connectivity is key decision.

• Embedded is secure and reliable, but expensive. Brought-in is low cost but less reliable. Each solution has benefits and risks.

• Vehicle manufacturers are taking both strategies.

• There will be no single solution. It will be a mix according to the services, VM and model.
