Cheers to the “Power-Obsessed”: Our Mobile IoT Mantra

Polte power savings

In honor of this week’s PolteCasts episode, The Power of Low Power IoT with Sony Semiconductor Israel’s (formerly Altair Semiconductor’s) VP of Product Management and Marketing Dima Feldman, we wanted to spend a bit of time discussing why we are so “power-obsessed.”

You might have heard the news by now – but leveraging 4G & 5G networks, Polte has developed a less expensive and more secure alternative for IoT location, using significantly less battery than other location technologies. What you might not know though, is exactly how Polte has taken its partners’ trackers’ battery life from days to years. 

Here’s how we avoid the battery blues.

How We Do It

Less Baggage

Built by the same global standards group that brought us 4G LTE and the 3G technologies that power today’s smartphones, 3GPP’s Cellular IoT standards are the precursor to 5G Massive IoT. These include NB-IoT and CAT-M (aka LTE-M/LTE-M1), which answer the need for IoT cost and power savings that legacy IoT radios could not fulfill. CAT-M, in particular, has a maximum system bandwidth of 1.4 MHz, making Cat-M chipsets notably smaller and less expensive. The key benefit here for IoT is that Cat-M is deployed throughout the world and already compatible with existing LTE networks.

GPS, Wi-Fi, and Bluetooth technologies inherently kill batteries, and a combination is required for indoor and outdoor tracking. Because many IoT projects do need inside and outside positioning, businesses are forced to load up their devices with extra chips, resulting in extra power drain. Polte eliminates the need for additional antennas, chips and power usage by turning a single cellular chipset into a replacement for these competing technologies. 

Quick Scanning (Indoors and Outdoors)

We’re able to perform a location scan in a few seconds – rather than taking up to several minutes like power-hungry GPS solutions. Limiting this action “on air” means that Polte is not straining the battery for an extended duration of time while capturing location data. Instead of trying to utilize signals from satellites 12,500 miles away that can not be seen indoors or under cover, Polte acquires data from local cell towers and existing infrastructure to determine location – significantly more quickly, using much less power.

LTE Power Optimization Features

GPS enabled devices may be able to store localized “warm start” data (offering the ability to restart a device without turning the power off), but will fall out of the original satellite constellation’s view. When this happens, it forces the device to “cold start,” which can take up to several minutes. Even if the device stays in view, it will also likely need to cold start if the necessary data isn’t collected in 5 minutes or sooner. In some cases, GPS may not find a signal at all.

Polte allows device battery life to stretch over months and years, enhanced by the ability to quickly reattach to the cellular network as well as “sleep” between necessary attachments. We’ve augmented our solution by taking advantage of LTE power optimization features designed for IoT, such as eDRX and PSM.

Power Save Mode (PSM) is a mode in which the User Equipment (UE) tells the network it is going to go dormant, or “asleep,” for a pre-negotiated amount of time. When the UE host device decides (based on directed logic or a timer) that it is time to transmit, it “wakes up” without requiring a “cold start” or reboot. eDRX (Extended Discontinuous Reception) simply lengthens the time a device is not listening to a network, and can be used in conjunction with PSM to enhance power savings.

Cloud Computing

Polte doesn’t calculate location on the device itself, but rather in the Polte IoT Cloud. This delivers both higher security for the end user, as well as less power consumption on the device. The processing demand is removed from the sensor and shifted to the Polte IoT Cloud, where our patented super resolution algorithms do the legwork to position your device.

Why it Matters

In short, Polte is disrupting the world of IoT location through equipping connected devices with considerably longer battery life.

This, in turn, delivers:

Polte unlocks an infinite number of new use cases that in the past were not possible due to the size, power and cost constraints of yesterday’s technologies. 

Incorporating Polte’s Cloud Location over Cellular (C-LoC) technology, enterprises now have visibility to track even the smallest assets power and cost effectively
