In-vehicle connected services ride the LTE wave

Keywords:in-vehicle  LTE  2G  3G 

For example, LTE technology is evolving to LTE Advanced to deliver even faster speeds. The industry is also still figuring out the best way to handle traditional voice and SMS text services over LTE networks.

What all this connectivity means is that you can't build a solution designed specifically for LTE networks as they exist (or as you think they will exist) in 2014. You need to build in flexibility to adapt the solution as LTE technology evolves.

Hints and tips
Clearly, some challenges remain before we see the full-scale vision of the LTE-connected car realised in every driveway. But the promise and momentum of LTE are too great to ignore. As system designers evaluate LTE devices and vendors in the coming months, here are some important factors to keep in mind:

 • Choose cellular vendors with proven expertise building LTE, 3G, and 2G devices that operate successfully in real-world multi-mode environments.
 • Look for wireless providers with expertise in the often-overlooked field of antenna design and testing, and that have proven successes delivering different types of devices (USB modems, hotspots, networking devices, etc.) in many parts of the world.
 • Seek out programmable wireless solutions with operating system-like capabilities, if not actual lightweight operating systems. You will need this headroom to keep pace with evolving LTE technologies.
 • Choose partners who have close relationships with operators in markets around the world and experience certifying solutions for multiple networks. This expertise will be extremely important as you shepherd your system through the sometimes-difficult certification process.

There can be little doubt: LTE is the future of in-vehicle connected services. By making smart choices now, system designers can be confident that their solutions will fulfil the full promise of the connected car—in 2014 and beyond.
