Wi-Fi HaLow™: Wi-Fi® for IoT applications (2020)
Wi-Fi HaLow offers a single, open, industry standard that can address many IoT applications in multiple industries. It combines the reach, robustness, scalability, and energy efficiency required by IoT systems, with the added benefits and capabilities of Wi-Fi. Operating in sub-1 GHz radio frequency spectrum and using narrower channels enables Wi-Fi HaLow to provide up to 100 times longer range than other IoT technology options. It can penetrate through building materials, ensuring successful home and building automation installations without costly meshes or repeaters, and connect devices approximately one kilometer or more from the AP while other IoT technologies were designed to only reach 10 meters. Wi-Fi HaLow uses several methods to achieve higher energy efficiency than most existing low power WANs and wireless PAN technologies. Using new MAC improvements and sleep modes, Wi-Fi HaLow supports devices powered by coin cell batteries; it can effectively handle sensor networks in varied environments, with increased capacity to support up to 8,191 devices per SSID.
IEEE 802.11be: Wi-Fi 7 Strikes Back
Abstract
As hordes of data-hungry devices challenge its current capabilities, Wi-Fi strikes back with 802.11be, alias Wi-Fi 7. This brand-new amendment promises a (r)evolution of unlicensed wireless connectivity as we know it. With its standardisation process being consolidated, we provide an updated digest of 802.11be essential features, vouching for multi-AP coordination as a must-have for critical and latency-sensitive applications. We then get down to the nitty-gritty of one of its most enticing implementations—coordinated beamforming—, for which our standard-compliant simulations confirm near-tenfold reductions in worst-case delays.

Are you ready for Wi-Fi 6E/7 testing? We are! (North America/Europe) - by Rohde & Schwarz.
Summary
The demands for faster wireless access and lower latency are continuously increasing. To meet these demands and to drive new use cases, regulatory bodies around the world open up spectrum in the 6 GHz band for unlicensed use. This new spectrum allows the Wi-Fi 6 standard, IEEE 802.11ax, to unfold its full power. It will also pave the way for the successful deployment of the next evolutionary step: Wi-Fi 7. In this webinar we will elaborate on the technology and regulatory status of Wi-Fi 6E. We will discuss related test challenges and demonstrate new test solutions which perfectly fit for Wi-Fi 6E and Wi-Fi 7 testing. Additionally, the webinar will provide you with an early overview on the upcoming Wi-Fi 7 standard, IEEE 802.11be.
In this webinar, you will learn about: (1) Wi-Fi 6E technology features and regulatory updates;(2) Wi-Fi 7 technology outlook; and (3) test solutions for Wi-Fi 6E, Wi-Fi 7 and more.
Webinar: Realizing extreme high throughput with Wi-Fi 7
By Staff | Rohde & Schwarz |
Summary
Wi-Fi 6/6E is just entering the market, promising more efficient operation and making use of additional 1.2 GHz of spectrum. However, the demand for much higher data speed and lower latency is unabated. The industry is already working on the next generation of Wi-Fi: IEEE 802.11be or Wi-Fi 7. Wi-Fi 7 is expected to provide data rates as high as 40 Gbps, essentially enabled by use of wide channels, higher modulation schemes and multilink operation. This webinar will give a comprehensive introduction to the new IEEE 802.11be standard, explain the related test challenges and how to solve them. In this webinar, you will learn more about: (1) key features of the IEEE 802.11be standard; (2) upcoming test challenges; and (3) Wi-Fi 7 testing solutions for access points and stations.

Instalação, configuração e teste
Micropython ESP32 é uma linguagem de programação compacta, porém eficiente, derivada de Python 3. Ela inclui diversas subfunções da biblioteca padrão do Python e é otimizada para rodar em microcontroladores e ambientes com restrições. Diferentemente da IDE do Arduino, cuja linguagem de programação utilizada é a C/C++ e Wiring, iremos utilizar o ambiente de programação uPyCraft . Ela é uma IDE com um design simples e de fácil utilização.

IEEE 802-11 - IEEE 802.11 TM WIRELESS LOCAL AREA NETWORKS is the Working Group for WLAN Standards
Wi-Fi Alliance® - The Wi-Fi Alliance® is the worldwide network of companies that brings you Wi-Fi®, one of the world’s most valued communications technologies. Our vision is to connect everyone and everything, everywhere. Wi-Fi Alliance drives global Wi-Fi adoption and evolution through thought leadership, spectrum advocacy, and industry-wide collaboration. The alliance´s work includes the development of innovative technologies, requirements, and test programs that help ensure Wi-Fi provides users the interoperability, security, and reliability they have come to expect.
TIP - The Telecom Infra Project (TIP) is a global community of companies and organizations that are driving infrastructure solutions to advance global connectivity. Half of the world’s population is still not connected to the internet, and for those who are, connectivity is often insufficient. This limits access to the multitude of consumer and commercial benefits provided by the internet, thereby impacting GDP growth globally. However, a lack of flexibility in the current solutions – exacerbated by a limited choice in technology providers – makes it challenging for operators to efficiently build and upgrade networks.
The goal of the Open AFC Software Group is to develop a reference open source implementation of an Automated Frequency Coordination (AFC) system that enables unlicensed devices in the newly available 6 GHz band to operate outdoors and increase their range indoors while ensuring existing services are protected.
WIA - The Wireless Infrastructure Association (WIA) represents the businesses that build, develop, own, and operate the nation’s wireless infrastructure. WIA advocates for the widespread, responsible deployment of wireless infrastructure to enable connectivity everywhere. The Wireless Infrastructure Association (WIA) is the USA National Sponsor of the registered apprenticeship program known as TIRAP. Since 2017, WIA has administered National Standards of Apprenticeship along with the United States Department of Labor approved, apprenticeable occupations associated with the program. Graduates of the program receive a national, industry-recognized credential that certifies occupation proficiency and provides opportunities for career advancement. WIA’s approach, working with participating employers and industry advisors, promotes a consistency and uniformity in training across occupations.
