Could broadband someday become ubiquitous in cars? New technology is blowing the doors wide open on making broadband the next hot auto accessory.

Take Autonet Mobile, for instance. Customers can buy Autonet’s in-car Wi-Fi routers via Amazon or select GM dealers, and create a hotspot within 150 feet of their vehicles. Passengers (not drivers!) can surf the web, connect to social networks, watch online videos, listen to Internet radio, instant message and play games, and take advantage of Internet-based navigation systems. Along similar lines, Autonode offers a range of wireless solutions targeted to everyone from mainstream consumers to the military. And for larger vehicles such as trucks and RVs, Ground Control features a mobile satellite Internet system that claims to connect the user to high-speed Internet wherever they can see the sky.

Still, some tech-savvy consumers have decided to take matters into their own hands. A recent New York Times article highlighted how consumers are installing computers in their cars to connect navigation, music and video playback systems. And car companies are now tuning into this demand and even working with customers to make modifications to their tech amenities. For example, when Ford Motor realized customers were modifying Sync, its voice-activated music and navigation system, the company asked university students to propose new features for the system.

So just when you thought you were already wired, the next frontier emerges. Soon, you too, may decide broadband is the best way to sync the entertainment and information systems you need on the road. And, with in-car Internet technology still evolving, this option will likely become even more attractive over time.
