Amazon Ventures Into The IoT Field

E-commerce giant Amazon is opting for a more straightforward approach for its IoT connectivity through Sidewalk. Sidewalk is a long-range wireless network for IoT devices to further enhance Alexa, it’s virtual assistant.

Amazon’s has been very active in the IoT marketplace. The launch of Sidewalk, a new low-bandwidth, long-distance wireless protocol to connect simple IoT devices such as trackers, sensors, and lightbulbs. Others should be watching this particular move very closely. For a company that starting as a book selling business, and has had undoubted sucess, becoming a technology mogul could be next.

The low-power, wide-area network (LPWAN) will use unlicensed spectrum in the 900MHz band. The 900MHz band is capable of securely sending data to devices up to a mile away, which supports features such as secure over-the-air (OTA) updates.

Amazon In a League of Their Own

“Bluetooth has limited range. Wi-Fi only goes so far. And 5G cellular is incredibly important when you need reliable, long-distance, guaranteed delivery of data, but it can be complex. That leaves a middle ground for devices that are looking for low-cost, low-power, low bandwidth connection where battery life needs to is years, not days,” said Dave Limp, senior vice president of devices for Amazon.

Amazon expects developers to build consumer-based, low-cost products for the Sidewalk network. Such as garden weather stations, water sensors, connected mailboxes, and dog trackers, Limp said.

A key feature of Sidewalk is that it’s based on mesh networking technology. As more devices that support Sidewalk power up, the stronger the network becomes. Eliminating the need for widespread infrastructure deployment associated with wireless and cellular networks.

Amazon Sidewalk R&D

The e-commerce giant says that after testing the Sidewalk protocol on 700 devices among the company’s employees at its subsidiary Ring, the network covered the Los Angeles Basin within three weeks. “We learned that, with just a few access points, very broad coverage becomes available,” Limp said.

Amazon plans to make a dog tracker called Fetch, which will be available next year. Ring Fetch will use Sidewalk and send an alert to pet owners when pets leave a certain perimeter.

Sidewalk will give Amazon massive amounts of information about behaviors and activities which the company did not have access to previously, according to Forrester analyst Jeff Pollard. “If use cases like home automation or IoT devices make use of this technology, they generate telemetry data. Connected devices – especially in the home – give vast amounts of information about your behaviors and activities, which could also go to Amazon with this connectivity.”

As connected devices communicate back to a management console or a manufacturer for support purposes, the data will become readable by Amazon, according to Pollard. Even further, if Amazon successfully creates city-wide IoT networks through its devices with relatively few access points, then the appeal of Sidewalk to developers eager to attract broad audiences can be far-reaching.

The Wide Web of Amazon

Amazon’s cloud-based voice service, Alexa, is available on more than 100 million devices. Conveniently, all of the companies devices tie into the cloud-based voice service. Connecting networks can happen at much lower cost than traditional wireless cellular-based technologies.

Sidewalk will need to contend with wireless technologies like Bluetooth, cellular, and Wi-Fi. As well as face competition from existing Low Power Wide Area (LPWA) standards Narrowband IoT, LTE-M, LoRa, and Sigfox. All of which already have developer support and are expanding in coverage globally. However, with Amazon’s massive customer-base and continued advancements in wearable, mobile, and home devices, Sidewalk could emerge as a colossal game-changer in the IoT connectivity space in the future.
