Tesla taps AT&T to bring cellular connection to its cars

The connected cars will be able to share performance data for remote maintenance, as well as provide Internet access in the vehicle itself.

Tesla will be able to tout one more feature in its advanced electric cars: a cellular connection.

The upstart automaker has partnered with AT&T to bring a 3G or HSPA+ (what AT&T calls 4G) connection to its electric cars. With a modem and SIM card, the cars will be able to share performance data, allowing for better remote diagnostic and maintenance, while passengers have the option to browse the Internet, watch videos, or get real-time traffic info via the connection.

The connection also will allow Tesla engineers to look at driving data from the car and better analyze performance trends, system enhancements, and driver preferences.

Ericsson Aims to Bring Cell Signal Everywhere, One Dot at a Time

Ericsson Dot System – CNET

Ericsson introduces the Radio Dot System, which is designed to bring cell phone signal to hard-to-reach places, such as the inside of a big building. Called the Radio Dot System, this system consists of multiple disc-shaped radio broadcasters called Dots. Each Dot can “provide high-quality access to mobile broadband and voice services” for the surrounding area, and multiple Dots can be used together to broaden the coverage indoors. To be clear, this system is designed to bring real cellular signal to where it can’t reach before, not use broadband network as a substitute, like AT&T’s MicroCell femtocell. It’s expected that the Ericsson Radio Dot System will be available to customers by the second part of 2014.
