Hurricanes are not so uncommon nowadays in the USA. Many a times the terrestrial infrastructure gets severely damaged or destroyed. In that situation, one of the easiest way is to use satellite backhaul along with COWs (Cell On Wheels). During Hurricane Ida, Verizon Response Team set-up a COW with satellite backhaul to ensure LTE and Wi-Fi connectivity for the First responders in Louisiana. One video is embedded below: Frankly, it's not just in USA where satellite connectivity helps. SpaceX's Starlink came to rescue of German communities impacted by disastrous floods last year.  Starlink satellite broadband connecting German communities ravaged by floods, including phone and internet outages. "We have never seen such a disaster. It's really devastating," said the Rhineland-Palatinate state governor, Malu Dreyer. @Tesmanian_com https://t.co/3EpvFOGkm5 pic.twitter.com/lnEutCAN6W — Gary Lerude (@MWJGary) July 27, 2021 Of course when the infrastructure gets damag...

In previous posts we looked at how OneWeb is trying to implement 5G in their satellite networks from the start. In a recent talk at 5G Forum Korea, Massimiliano Ladovaz, CTO of OneWeb presented their Vision for LEO Satellites and 6G connectivity Any issues OneWeb was facing, are past problems , and in the last year they have not only sorted that out but also managed to make good progress with their launches.  Mission Success! We are thrilled to have ended the year with another successful launch, with contact received from all 36 satellites. We have now launched over 60% of our constellation! Thanks to all our team and distribution partners for a great year! https://t.co/jn9YhCSlJe pic.twitter.com/vue4UBQW4I — OneWeb (@OneWeb) December 27, 2021 Back in December , OneWeb successfully launched 36 satellites, bringing total in-orbit constellation to 394 satellites. They have now launched over 60 percent of their LEO satellite fleet that has been promised to deliver high-speed, l...

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...

CW ( Cambridge Wireless ) is the leading international community for companies involved in the research, development and application of wireless and mobile, internet, semiconductor and software technologies. The Connected Devices Special Interest Group (SIG) within CW, focuses on applications, systems and underlying technologies of wireless communication where the end device is a machine or other device that’s not a handset. The group's scope encompasses the concepts of Machine to Machine (M2M) communication and the Internet of Things from the perspectives of key applications, systems design and technology. This includes wide-area networking (WAN), standard cellular communications, satellite systems and broadband, and where required local-area networking (LAN), Bluetooth, Near-Field Communications (NFC), Ultra Wide-Band (UWB), Wi-Fi, Zigbee, and other less well-known standards. Proprietary radio systems are also considered along with the data centre and back-office systems require...
