Meet PoLTE, a Dallas-based startup that wants to make location-tracking more efficient. Thanks to PoLTE’s software solution, logistics and shipment companies can much more easily track packages and goods. The startup is participating in TechCrunch’s Startup Battlefield at Disrupt SF.

If you want to use a connected device to track a package, you currently need a couple of things — a way to determine the location of the package, and a way to transmit this information over the air. The most straightforward way of doing it is by using a GPS chipset combined with a cellular chipset.

Systems-on-chip have made this easier as they usually integrate multiple modules. You can get a GPS signal and wireless capabilities in the same chip. While GPS is insanely accurate, it also requires a ton of battery just to position a device on a map. That’s why devices often triangulate your position using Wi-Fi combined with a database of Wi-Fi networks and their positions.

And yet, using GPS or Wi-Fi as well as an LTE modem doesn’t work if you want to track a container over multiple weeks or months. At some point, your device will run out of battery. Or you’ll have to spend a small fortune to buy a ton of trackers with big batteries.

PoLTE has developed a software solution that lets you turn data from the cell modem into location information. It works with existing modems and only requires a software update. The company has been working with Riot Micro for instance.

Behind the scene PoLTE’s magic happens on their servers. IoT devices don’t need to do any of the computing. They just need to send a tiny sample of LTE signals and PoLTE can figure out the location from their servers. Customers can then get this data using an API.

It only takes 300 bytes of data to get location information with precision of less than a few meters. You don’t need a powerful CPU, Wi-Fi, GPS or Bluetooth.

“We offer 80 percent cost reduction on IoT devices together with longer battery life,” CEO Ed Chao told me.

On the business side, PoLTE is using a software-as-a-service model. You can get started for free if you don’t need a lot of API calls. You then start paying depending on the size of your fleet of devices and the number of location requests.

It doesn’t really matter if the company finds a good business opportunity. PoLTE is a low-level technology company at heart. Its solution is interesting by itself and could help bigger companies that are looking for an efficient location-tracking solution.
