Will Amazon Sidewalk accelerate IoT Adoption?

It has long been a dream of wireless telecom technologists to create a technology where devices can even connect to the network even if there is no direct coverage. In 3G days we used to call it Opportunity Driven Multiple Access ( ODMA ) but it was never standardised. Then we also have similar concept with multihop cellular network ( MCN ). Then you also have generic terms Ad-Hoc networks and Relays . There has been no shortage of repackaging the concept to create a network of networks . So what exactly is Sidewalk? Quoting from this Light Reading article : The Sidewalk network – which relies on Bluetooth Low Energy for short-range communication, 900MHz LoRa or frequency-shift keyring over longer distances – is set to max out at 80 Kbit/s on any Amazon device operating as a Sidewalk "bridge." And Amazon caps Sidewalk's per-customer data usage at 500MB a month. Amazon did notify customers about Sidewalk and it gave them opt-out instructions. But the shared network servic

5G Time Sensitive Networking (TSN) for Industrial Communications

One of the main requirements for 5G to be usable in Industry 4.0 scenarios is that it must be able to replicate the deterministic and low-latency nature of communication that would be expected as in case of wired networking. Last year, Devaki Chandramouli, Work Item Rapporteur at 3GPP, wrote an article titled, '5G for Industry 4.0'. Quoting from the article: In order to be able to deploy 5G for new and diverse use cases, including industry 4.0 and factory automation, the 5G system must work in harmony with the communications technologies used in such industries. For this purpose, 3GPP has now made significant progress towards the integration of the 5G system with IEEE 802.1 working group specifications covering Time Sensitive Networking (TSN). The ‘Vertical_LAN’ work item, in 3GPP Release-16, introduces the following three new and distinct 5G enablers for Industry 4.0; Support for Time Sensitive Communications by seamlessly integrating the 5G system as a bridge to IEEE TSN. Sup

Is 4G the new 2G in IoT?

With the 5G and NB-IoT hype in full swing, people can be forgiven when they think that NB-IoT is the dominant technology for the Internet of Things. More shocking for some people is the fact that there are no 50 billion IoT devices yet , even when non-cellular IoT technologies are included. At the recently concluded 5G Techritory conference, Jans Jelinskis, Technical Director, 1NCE highlighted the fact that finally, customers are coming round to the idea that there will be no 2G network in the future, so the future of cellular IoT will be 4G. While many of the existing IoT requirements are still getting satisfied by the 2G simplicity, plan B also includes other non-cellular LPWA IoT technologies like LoRaWAN & Sigfox. Time will tell which of these will succeed and which of them will disappear into oblivion. Here is the video of the talk Related Posts :  The 3G4G Blog: Are there 50 Billion IoT Devices yet?

Rethinking LiFi for Low-Power and Long Range RF Backscatter

Interest in zero-energy/low-energy IoT is gaining ground as the industry tries to introduce more of these with minimal impact to the environment. A research team of IMDEA Networks Institute has introduced Internet of Things (IoT) devices that communicate without any batteries and harvest energy and receive data through visible light. A news article reported: This represents a new step towards making battery-free devices a reality, through the convergence of two emerging technologies: LiFi and radio frequency (RF) backscatter. Potential applications include smart homes, smart cities, and smart agriculture. It is expected that more than 64 billion IoT devices will be deployed by 2025, and they will work with batteries. The chemical components of these batteries threaten to have a huge environmental impact on the Earth. There is a pressing need to find a solution for removing the batteries without affecting communication performance and IoT services. IMDEA researchers propose that IoT de

NTT Docomo and Airbus Demonstrate Zephyr HAPS Wireless Broadband Connectivity

NTT Docomo and Airbus have demonstrated the ability to use Airbus's solar-powered Zephyr High Altitude Platform Station (HAPS) to deliver future wireless broadband connectivity. The trial took place in the United States in August, when the Zephyr S aircraft undertook approx. 18-day stratospheric flights to test various capabilities. We have covered many of the topics here, see related blog posts link at the bottom. A press release said: Carrying an onboard radio transmitter, the Zephyr S provided an agile datalink during a stratospheric flight to simulate future direct-to-device connectivity. Test data was captured at different altitudes and at different times of day and night, focusing on assessing how connectivity is affected in the stratosphere by factors including weather conditions, different elevation angles and aircraft flight patterns. Tests included various bandwidths to simulate direct-to-device service from the HAPS to end users using low, nominal and high throughput. T

Industrial 5G – for the industry of tomorrow

According to Siemens , Industrie 4.0, the smart factory, the Industrial Internet of Things (IIoT) – these are the future of industrial manufacturing. Designing production plants and intralogistics to be more flexible, autonomous, and efficient requires the right communication framework and comprehensive connectivity. The new 5G communication standard opens up important new prospects. We have covered quite a few tutorials on Industrial IoT, Industry 4.0 and Private Networks. If you do not have a background on these topics, please see the related posts at the end of this post before proceeding further. At the 5G-Industry Summit back in September, Sander Rotmensen, Director Industrial Wireless Communication, Siemens AG spoke about how Industrial 5G will enable the industry of tomorrow. The abstract states: Industrial 5G opens the door to comprehensive wireless networking of production, maintenance and logistics.
