What is LoRa?

LoRa (short for long range) is a spread spectrum modulation technique derived from chirp spread spectrum (CSS) technology. Semtech’s LoRa devices and wireless radio frequency technology is a long range, low power wireless platform that has become the de facto technology for Internet of Things (IoT) networks worldwide. LoRa devices and the open LoRaWAN® protocol enable smart IoT applications that solve some of the biggest challenges facing our planet: energy management, natural resource reduction, pollution control, infrastructure efficiency, disaster prevention, and more. Semtech’s LoRa devices and the LoRaWAN protocol have amassed several hundred known uses cases for smart cities, smart homes and buildings, smart agriculture, smart metering, smart supply chain and logistics, and more. With well over 100 million devices connected to networks in 100 countries and growing, LoRa devices are the DNA of IoT, creating a Smarter Planet.

LoRa Wireless RF Technology

A Semtech innovation, LoRa devices offer compelling features for IoT applications including long range, low power consumption and secure data transmission. The technology can be utilized by public, private or hybrid networks and provides greater range than Cellular networks. LoRa Technology can easily plug into existing infrastructure and enables low-cost battery-operated IoT applications. Semtech builds LoRa Technology into its chipsets which are incorporated into devices manufactured by a large ecosystem of IoT solution providers, and connected to LoRaWAN-based networks around the globe. Simply stated, LoRa connects devices (or all things) to the Cloud.

Thanks to LoRa and our other innovations, YoLink is redefining "Smart Home"

"Smart home?" Think bigger! Take your wireless devices where you never thought possible before: to the backyard, to separate garages, to sheds, barns, mailboxes and beyond. Our products are used in high-rise buildings, thanks in part to 900MHz band Chirp Spread Spectrum technology that allows transmission through multiple storeys of reinforced concrete. 

What is Control-D2D?

Control-D2D is a wireless device-to-device protocol that adds the ability to pair one wireless device to one or more (up to 128!) other wireless devices, to establish a link or relationship between the devices, that will remain and will carry out the desired action when required, even if WiFi, internet and AC power are no longer present. These feature is not commonly found in smart wireless devices and is for the most part unique to YoLink in the smart home industry. The process is incredibly easy and takes no more than a minute to set up. 

Control-D2D pairing is perfect for critical applications, such as security/intrusion detection and for water leak detection and automatic water shut-off (and it is a big part of our Water Leak Protection System, a complete water leak detection and automatic shut-off solution protecting customers against the loss and expense that often comes with water leaks (learn more here).

What can I do with Control-D2D?

• You can pair a smart siren to activate upon any alarm (motion sensor, vibration sensor, water leak sensor, etc.).
• You can pair your leak sensors to a smart motorized valve or wireless valve controller.
  
• You can pair a smart plug or light switch to a motion sensor or door sensor.
  
• You can pair a smart fob to a garage door operator.
