Webinar 18 nov. 2020
Al Global Summit Logistics & Supply Chain, webinar tenuto da Paola Visentin lungo queste le distintive dei sistemi RFID (tag, controller, antenne e periferiche) e Bluetooth LE (Beacon, EchoBeacon e Gateway), evidenziando, tra le ultime novit, il sistema Beacon Wake-up & Activator per la rilevazione precisa della presenza di item/persona, capace di acquisire il dato con accuratezza e di trasmetterlo a lunga distanza, e il sistema BluEye per la sicurezza in funzione anti-Covid19 (allarme di prossimit, allarme assembramento e contact tracing).
This document discusses various Internet of Things (IoT) protocols. It defines IoT as interconnected devices that can transmit and receive data over a network. It then covers common network topologies and constraints of IoT devices. Several wireless protocols are described in detail, including their typical range, power usage, data rates, and costs. Popular protocols for messaging (MQTT) and REST-like interfaces (CoAP) are also summarized. The document aims to provide an overview of the IoT protocol landscape to help people get started with IoT development.
The Role of the Communication Protocols in the IoT: Pitfalls and AdvantagesFabio Gatti
油
IoT solutions should rely on solid basis in order to provide a step for the future. One of the foundation of building IoT solutions is identifying the appropriate communication protocol to use. Choosing among the different communication protocols may be a challenging task due to the fact that some protocols may be the right fit for one scenario but not necessarily for all.
In this session, we will examine the communication protocols including their pitfalls an advantages and how to choose the right one for your solution.
This document provides a high-level overview of protocols for the Internet of Things (IoT). It discusses some of the key challenges for IoT including scalability, configurability, interoperability, discovery, and security. It then reviews several common IoT protocols, including HTTP, WebSockets, MQTT, CoAP, and mentions others like AMQP and XMPP. For each protocol, it summarizes their purpose, model (e.g. publish-subscribe vs client-server), efficiency considerations, and role in the protocol stack. It emphasizes that existing protocols like MQTT and CoAP are preferable to reinventing the wheel for IoT.
Standards are driving the growth of the Internet of Things by enabling new business models, rapid development, and global markets. Key standardization activities include work by the IETF on networking protocols like IPv6, CoAP, and security, as well as work by OMA, IPSO Alliance, and OneM2M on lightweight M2M, web objects, and a common M2M system standard. Building a Web of Things involves using standards like CoAP, 6LoWPAN, and IPSO web objects to connect M2M devices to backend systems over various network types.
Zach Shelby, Chief Nerd and co-founder of Sensinode, gives a high-level tutorial of the new OMA Lightweight M2M standard for Device Management, Network Mangement and Application Data for the Internet of Things. This new CoAP and DTLS based standard provides a complete system interface solution for M2M devices and services.
This document summarizes several wireless networking standards and protocols used in IoT applications. It discusses protocols for different layers including transport, discovery, data, and device management. Specific standards covered include 6LoWPAN, EPC, WiFi, Bluetooth, ZigBee, and different versions of WiFi (802.11b, 802.11g, 802.11a, 802.11n). Key differences between the standards are highlighted such as operating frequency bands, maximum data rates, and effective transmission ranges. The document provides an overview of the organizational layers in which various IoT protocols operate and the rapid development of new protocols to meet diverse IoT requirements.
