Estimates suggest that only 10% of the world’s surface has terrestrial connectivity. To establish a truly connected planet with ubiquitous coverage for massive Internet of Things (IoT) deployments, we need to complement terrestrial networks with satellite connectivity, expanding coverage for demanding verticals. The LoRa Alliance® recently upgraded its guidelines to include Long Range Frequency Hopping Spread Spectrum (LR-FHSS) data rates for the LoRaWAN® standard. The LR-FHSS features significantly increase network capacity and reduce interference, facilitating new deployment opportunities across the globe.
Location is a vital component of the Internet of Things (IoT), encompassing the ability of things to sense and communicate their geographic position. Location data helps organize, track and account for the billions of Internet-connected devices based on sensors and other location-centric elements within them. The ability to capture location data forms the basis of location-based services and starts with the physical radio frequency (RF) technologies that interact with the world around them.
Several technologies, such as GPS, LoRa® and others, can provide outdoor location information. However, these existing technologies are not optimized for IoT asset tracking use cases due to their increased power requirements which require access to frequent charging as well as inability to work indoors. Reducing power consumption on devices fundamentally requires a reduction of compute on device, with IoT this can be accomplished by partitioning the workload between the device and harnessing the power of the Cloud. For precise indoor location, where GPS has no tangible reach, and to enable continuous location detection or tracking, indoor positioning systems (IPS) technologies such as Wi-Fi come into play.
The LoRaWAN® standard has been officially approved as a standard for low power wide area networking (LPWAN) by the International Telecommunication Union (ITU), the United Nations specialized agency for information and communication technologies.
In the coming years, data center traffic will continue to see immense growth. Cloud services, Internet of Things (IoT) and ever-increasing broadband demand are driving a massive push by hyperscale data centers and wireless operators towards 200G and 400G. Optical modules, key building blocks for connecting data center equipment, must also evolve to meet these bandwidth demands with greater density, lower power consumption and lower latency.
We are pleased to introduce our newest line of sensors, PerSe™, for the personal connected consumer market. Derived from the term, Person Sensing, the PerSe product line of sensors features three core product families – PerSe Connect, PerSe Connect Pro and PerSe Control. The sensors intelligently sense human presence near a mobile device and enable advanced Radio Frequency (RF) control when a user is in close proximity - delivering high quality connectivity and throughput, in smartphones, laptops and wearables while providing compliance with global safety standards
Often, there is no warning of a natural disaster, and the consequences can be costly. After an event like a hurricane, tornado, earthquake, flood, or wildfire, communities need help to cover the costs for debris removal, life-saving emergency protective measures, and restoring public infrastructure. The recently passed American Rescue Plan Act of 2021 is helping communities do that, allotting $50 billion for the Federal Emergency Management Agency’s (FEMA) Disaster Relief Fund to help state and local governments respond to and recover from these major disasters or emergencies.
IotaComm, TEKTELIC and Semtech recently announced a product development and licensing agreement to develop a gateway based on the LoRaWAN® standard and Semtech’s LoRa® chipset.
Semtech’s Tri-Edge™ GN2255 is the industry’s first analog IC solution enabling ultra-low latency, less than 1.5W module power, and performance for up to 10km reach for 50Gbps PAM4 SFP56 optical modules. Based on the proven Tri-Edge CDR platform qualified in data center applications, the new solution delivers the cost effectiveness, small footprint, low power, ultra-low latency, and performance demanded by 5G front haul applications. The new Tri-Edge GN2255 enables 50Gbps PAM4 links that will double the bandwidth of currently deployed 25Gbps NRZ front haul links. Semtech’s introduction of the Tri-Edge 5G wireless IC will help support new 5G applications, including edge computing, enhanced mobile broadband and device streaming, and fixed wireless access (i.e., home Internet). Learn more about the product announcement here.
Earlier this year, Evaluation Engineering (EE) spoke with Raza Khan, senior marketing manager in Semtech’s Signal Integrity Products Group to discuss industry trends and the new Tri-Edge 5G wireless product.
The number of Internet of Things (IoT) devices deployed across the globe is expected to triple over the next decade. As a result of this growth, there’s a need for more low power connectivity to process the small amounts of data these devices produce quickly and securely. Moreover, with 2G and 3G networks sunsetting, enterprises are in need of a low power wide area (LPWA) network that is cost-effective and reliable in order to provide the connectivity needed to power IoT applications across a variety of industries.
The LoRa Alliance®, an open, non-profit global association that develops, maintains and promotes the LoRaWAN® protocol for low power wide area networks (LPWANs), has expanded its guidelines to include Long Range - Frequency Hopping Spread Spectrum (LR-FHSS) data rates. The LR-FHSS rates significantly increases network capacity and robustness to interference – opening the door to new deployment opportunities across the globe.
