How to Make IoT Batteries Last Longer

Make IoT Batteries Last Longer: IEEE Wake-Up Radio InfographicAnalyst firm Gartner predicts that there will be 8.4 billion connected “things” in 2017, which will then expand to 20.4 billion Internet of Things (IOT) devices by 2020. That number is staggering. And it is reasonable to expect that a great many of these devices will run on batteries. Yet battery life can be limited. How do we make IoT batteries last longer?

Consider the use cases:

  • Wearable medical devices that cannot be hard wired
  • Logistics sensors on vehicles, moving from place to place
  • Agricultural IoT devices in the middle of fields
  • Smart home consumer devices that are easier to install without hardwiring, increasing market adoption

…and these are just a few instances of the many IoT use cases that will require battery operated devices. Given the sheer number of devices, it is essential that IoT manufacturers create devices that have a long battery life while maintaining optimal performance. We must make IoT batteries last longer.

This is why the IEEE 802.11ba standards working group is developing the IEEE Wake-Up Radio standard. This technology has the potential to increase battery life in IoT devices from months to years. When you consider the cost of replacing 20.4 billion batteries (both the batteries themselves, as well as the time involved), this will have significant economic impact.

How it Works

IoT devices have an embedded radio that has to “wake up” in order for data to be transmitted. The longer the device is awake, the more power it consumes, but the higher the performance. To solve the power issue, a 2nd, low-power, duty-cycled Wake-Up Radio is added to the device that waits for transmissions. This Wake-Up Radio only wakes up the main device when it is needs to, allowing a longer device sleep state without compromising performance. Ensuring that the Wake-Up Radio uses duty cycling increases the battery life even more.

The result is a high-performance IoT device that last for years rather than months on a single battery.

The impact is clear. IoT devices that will run on IEEE 802.11 (Wi-Fi®) connections need IEEE Wake-Up Radio. Device manufacturers need this information now, in order to build this into their IoT devices of tomorrow.

IEEE Technology Report on Wake-Up Radio

To help IoT device manufacturers prepare for IEEE Wake-Up Radio even before the standard is released, IEEE is offering a technology report that outlines the technology, use cases, and more. The report will be released on 2 November, 2017, and is available for pre-sale now. Device manufacturers that begin planning for IEEE Wake-Up Radio now will have a competitive advantage, especially in consumer categories where IEEE 802.11 (Wi-Fi®) connections are ubiquitous. They will be able to make IoT batteries last longer in their devices.

Increasing battery life in IoT devices is essential. When it comes to devices that run on IEEE 802.11 (Wi-Fi®) connections, IEEE Wake-Up Radio is the solution. Pre-order the IEEE Technology Report on Wake-Up Radio now, and prepare your organization for a competitive advantage in the future.

Low-Power, Low-Latency IoT Devices Will Transform the Logistics Industry

Low-power, low-latency logistics industry

We often hear about the Internet of Things (IoT) in consumer devices, but the IoT is transforming industry as well. From smart warehouses to smart agriculture to retail to environment, there seem to be as many use cases as their are devices and sensors. And all of these devices need power as they collect and share data. To conserve power and efficiency with the wide breadth and sheer magnitude of the IoT, it will be crucial to utilize low-power, low-latency IoT devices. This is especially true for businesses in supply chain management, as these devices will particularly transform the logistics industry.

Delivery and fulfillment companies generally use third-party logistics (3PL) in their operations, which involves a business transporting products and resources through outsourced services. According to Meola (2016), the IoT will impact the following aspects of this process:

  • Asset Tracking in Supply Chain Management: Whereas freight and shipping companies have previously tracked and managed inventory using barcode scanners, IoT solutions (such as RFID tags) are beginning to offer more valuable data and make these scanners obsolete.
  • Inventory and Warehouse Management: In addition to RFID tags, logistics companies are using more internet-connected and satellite trackers to track specific items as they travel to their destination. Bluetooth tags and beacons allow tracking in smaller areas; retailers tend to use them for monitoring customer traffic and customizing marketing messages.
  • Fleet Management: IoT solutions using GPS and other tracking technologies provide real-time data on where vehicles are located and how they are operating. These solutions carry the potential to impact physical asset movement and delivery, consumer transportation, and field-service vehicles.

Combining the capability of IoT devices with low-power, low-latency attributes means longer-lasting devices as well as more reliable and more efficient analytics. More efficient analytics means more powerful customer support services and greater revenue. Wake-Up Radio from IEEE 802.11ba standards task group provides a low-power, low-latency solution that may be critical to IoT devices and sensors developed for the logistics industry.
