Semtech Corp. has partnered with Amazon.com Inc. on its new wireless network, Amazon Sidewalk, launching later this year. The Camarillo semiconductor and Internet-of-Things products supplier will make available to the Seattle e-commerce retailer its long-range, low-power LoRa platform for the Amazon Sidewalk network. Amazon Sidewalk is a free network for Amazon customers that allows them to simplify new device setup, extend the low-bandwidth working range of devices and help devices stay online and up-to-date even if they are outside the range of home Wi-Fi. The LoRa platform extends the range of a customer’s home network to connect outdoor with low-bandwidth smart home products, including smart lights, pet trackers, sensors for asset tracking, smart irrigation and a multitude of additional low-cost devices for residential use, the company said. Chief Executive Mohan Maheswaran said LoRa meets Amazon Sidewalk’s goal of providing the network support needed to connect a range of low-power home devices or sensors. “The collaboration with Amazon solidifies that LoRa is the de facto platform for (Internet-of-Things low-power wide-area network) applications and expands LoRa to new consumer applications,” Maheswaran said in a statement. Shares of Semtech (SMTC) closed down 96 cents, or more than 1.8 percent, to $51.17 on the Nasdaq, on a day when that market closed down less than a percent.
