C-V2X and 5G for Vehicular Connectivity

We have made couple of introductory tutorials on "Connected and Autonomous Vehicles (CAVs)" and another one on "Introduction to Vehicle to Everything (V2X) and Cellular V2X (C-V2X)". These provide you with the basics needed to understand the technology. In addition, we have also collected "3GPP Technical Specifications (TS) and Reports (TR) related to V2X" here . 5G Americas has recently published a white paper titled, “Vehicular Connectivity: C-V2X and 5G,” which covers the impacts of 5G-based cellular vehicle-to-everything (C-V2X) technologies on vehicles, embedded infrastructure, and intelligent transportation networks. You can download the PDF here and this page contains a presentation and a summary video. The paper also details how Multi-access Edge Computing (MEC), previously known as mobile edge computing, can help bring processing power near the vehicle to meet ultra-low-latency requirements, and to reduce network traffic towards a centralized

Helium - Another IoT Kid on the Block

We looked at the number of IoT devices on The 3G4G Blog post yesterday . As you may have already noticed, the number of unlicensed IoT devices are growing as well. The Helium network is a decentralized wireless network that enables devices anywhere in the world to wirelessly connect to the Internet and geolocate themselves without the need for power-hungry satellite location hardware or expensive cellular plans.  Helium uses an open-source LongFi architecture, which combines the LoRaWAN wireless protocol and the Helium blockchain. Hotspots also acts as miners on the Helium blockchain so owners can earn a new cryptocurrency (HNT), for building the network and transferring IoT device data. The Helium whitepaper says: Powering the Helium network is a blockchain with a native protocol token incentivizing a two sided marketplace between coverage providers and coverage consumers. With the introduction of a blockchain, we inject decentralization into an industry currently controlled by mono
