Polte raises $12.5 million to track devices using LTE signal

Published October 11, 2019

Polte has raised another $12.5 million. The company is building a service that leverages 4G (and potentially 5G) signal to track things for commercial and industrial use cases. The main advantage is that using cellular signal uses a lot less battery than acquiring GPS location and transmitting it over cellular.

Today’s funding round is an extension of the company’s Series A round. In 2017, Polte raised $6 million — and the company is raising another $12.5 million this year. Polte isn’t disclosing the list of investors. The startup participated in TechCrunch’s Startup Battlefield.

There are many potential use cases for Polte, but most of them involve tracking stuff on the move with as little battery as possible. You could use it for your supply chain, if you’re running a logistics or transportation company, in the energy or automotive industry, etc.

If you want to use an IoT device to track a package over multiple weeks, it can be a costly effort as you need to determine the location of the package using GPS and transmit the location of the package over the air. While GPS is insanely accurate, it also requires a ton of battery just to position a device on a map.

That’s why some devices rely on Wi-Fi signal to triangulate a position with a database of Wi-Fi access points. But that’s not as accurate, especially in the countryside.

Polte turns data from the cell modem into location information. It works with existing modems; Polte is a software solution. None of the computing is done on the device itself. Polte-enabled devices transmit 300 bytes of data back to Polte’s servers so the company can determine the location a few seconds later.

This way, you can use cheaper IoT devices to track packages. And if you’re running a company that wants to track thousands or millions of items, that could help you save a ton of money over the long run.

PoLTE lets you track devices using LTE signal

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.
