4G-EQUIPPED CARS NEXT STEP IS EVOLUTION

All new car's and truck's  is the best mobile computer ever invented. With plenty of space for data storage, wireless antennas, and multiple processors and LCD screens, driving a new car is like towing a data center with you to the beach  place. The problem is that all of that connected bliss has been limited to speeds of about 1 MBps or so. While your new phone might get some 4G service as you motor along, most cars themselves can connect only via 3G. 

That is changing, fast. We recently tested two cars—the new Audi A3 and  Cadillac ATS and that use a 4G data feed to connect at speeds of greater than 5 Mbps, creating a roving hotspot not only for the passengers in the vehicle watching The Blacklist on an iPad but also for the driver's smartphone or tablet. You can connect over 4G to the car,such as Pandora and iHeartRadio, and then play apps from your phone that run on the touchscreen  no need for  phone while you drive hands free. 

Driving with 4G means your music stream is less likely to be interrupted by spotty service, but it's about much more than that. A fast connection in the car is ushering in the age of vehicular processing, which will allow passengers to use data-intense apps such as full 3D map visualization, two-way video calling, HD or even 4K video streaming, surround-sound audio, and even multiplayer gaming PlayStation 4 or on the Xbox One , all in the car. A new age of mobile connectivity is coming. 

2015 Cadillac ATS

The Cadillac ATS mid-sized sedan is the smaller cousin to the Cadillac CTS and XTS full-size models. It's a sleek and nimble ride. The OnStar 4G LTE connection is also quite nimble. In our tests using the SpeedSmart iPhone app, we tested speeds of 6 to 10 MBps. To create a Wi-Fi hotspot in the car, you press the OnStar connection button on the rear-view mirror. Our test car was already configured with an SSID network name and password; you can set up one of your liking. Seven people can connect using any wireless device. 

GM says the antenna on the ATS is much stronger than the one that fits inside a smartphone or tablet, and is tweaked to make sure the cellular data connection remains consistent as you drive, jumping onto cell towers quickly. As long as you keep driving, the hotspot never runs out of power. You can also use the accessory mode with the engine turned off to keep the hotspot going for 30 to 60 minutes. 

One cool 4G perk: If you call an OnStar adviser, the agent can run a diagnostic on the car via the data connection, even while you're in motion. Previously, the OnStar agent could connect to speak to you but had to run the diagnostic tests after the call ended and then send the results. Someday soon, auto repair shops will be able to run these same diagnostics on your car. 

GM is slowly rolling out OnStar 4G throughout its entire fleet; about 30 cars will use the faster data connection in the next few months, including most GM cars in the Cadillac, Buick, Chevy, and GMC line-ups. Cadillac offers a three-month trial for every new owner. After that, you'll pay by the month—(that's right, your car has a data plan now). There's also a single day package as well as an annual plan. If you already use AT&T, you can add the ATS for a flat rate of $10 per month and shared data. 

2014 Audi A3

The A3 offers deeper connectivity via 4G. Google Earth and Google Street View both pop up immediately thanks to the faster feed. There are additional in-car apps available, from Twitter and Facebook to one for checking fuel prices and the weather. 

The A3 will provide a hotspot for only about 10 minutes after you put the car in accessory mode; there's no extended mode. As with the Caddy, your 4G speeds depend greatly on where you connect, how many other drivers are around, and the time of day. The Audi and the Cadillac produced similar speeds, and no surprise there—both use the AT&T network. Audi, however, offers its own set of data plans, which cover six months or even 30 months of service. Go above your data allotment, though, and you'll need to sign up for more. 

Audi does include a six-month trial with the A3, however, which is three extra months of free surfing over the Cadillac ATS. You can also add the A3 to your existing AT&T plan. 

More Than Entertainment

A 4G connection in the car means that everyone can connect their phone or tablet to watch movies, web surf, even control the Wi-Fi-connected sprinkler system in your home. It's great for those family road trips, too. Many kids' devices don't have cellular data, but they can stay connected (and occupied) through the connection to your hotspot. And in my tests, having a fast and reliable connection meant streaming over apps like Pandora actually worked reliably, without the typical glitchy behavior on 3G-connected cars. Having about 10Mbps on board means everyone share the bandwidth without hiccups.

Yet the future promised by 4G connectivity in cars is about more than streaming movies. Tim Nixon, the CTO of OnStar, told me the next wave of connectivity will probably focus more on diagnostics. When a GM car can connect reliably over 4G, he says, it will be that much easier for dealerships to connect to your car's systems and diagnose any problems. 

Of course, 4G is just the opening act of the connected car future. Cars will connect to the roadway, other vehicles, and a central car traffic control center over a wireless signal. (This won't be 4G. Current plans call for a more tightly controlled wireless signal called dedicated short-range communications, or DSRC, and it's currently in a testing phase.) When cars start driving on their own using sensors that look for problems on the road and adjust steering, braking, and speed autonomously, having a high-speed and secure connection will be crucial. Imagine an entire car network that adjusts in real-time to traffic flows, accidents, and road obstructions. We might not even need traffic lights, speed limits, or yield signs because the cars will all connect into a central grid. If we can get the network right, that is None of this is coming tomorrow, but it is coming.
