Audi recently announced a new model A8 - one of its top models - which will be connected to the Internet at 100 megabits / sec Obviously, the car will not be followed by an optical fiber but the LTE (Long Term Evolution) will be used. LTE is the standard that should be - over time - deployed for the 4th generation networks and flows should reach at least 100 megabits per second download.
Car requires, the system is mixed: the car itself is connected to the Internet and its LTE onboard computer - which incorporates the services of Google - can take advantage, while the passages will access the Internet via Wi-Fi: the car will incorporate an access point Wi-Fi capable of sharing the connection LTE.
This technique is already used on some models in conjunction with a 3G modem, but the rates are much lower: a maximum of 14.4 Mbps at Audi. Remains a (small) problem: if the car is capable of connecting to LTE, the LTE networks are still very rare and coverage of highways - even now - is not optimal with the simple 3G ...
