Wi-Fi to Dominate HD Video Home Networks

Digital home networks will be optimized to distribute video. Standards based 802.11n Wi-Fi technology will dominate the wireless High Definition (HD) video market, at least for the next several years, according to the latest study by In-Stat.

Three other connectivity technologies are competing in this space -- Wireless Home Digital Interface (WHDI), WirelessHD, and Ultrawideband (UWB). However, the ubiquity of Wi-Fi technology is proving unstoppable.

"802.11n is the next generation of the immensely popular Wi-Fi family. It promises data rates above 100Mbps and is backwards compatible," says Brian O'Rourke, In-Stat analyst.

The installed base of Wi-Fi is immense, and effectively includes all mobile PCs, many mobile phones and a wide variety of CE devices. The primary drawback to 802.11n is expense, since it requires codec technology on both ends to transmit HD video. Neither of its primary competitors, WHDI and WirelessHD, requires codecs.

In-Stat's market study found the following:

- UWB will not be a major factor in the consumer electronics market. Many chip companies are leaving the market in late 2008 and 2009.

- Nearly 24 million digital TVs will ship with some type of Wireless HD video technology in 2013.

- WHDI and WirelessHD are being promoted by startups, but they are new, expensive, and power-hungry, which is generally not a recipe for quick market success.

Business technology investment no longer follows a predictable path to growth. The global venture capital (VC) investment in artificial intelligence (AI) was close to its peak in 2021 reaching $22.3 billion, according to the latest worldwide market study by ABI Research. This is just $400 million shy of the historical high of $22.7 billion recorded in 2019. Compared to the $15 billion recorded in 2020, the market made a remarkable recovery, with a 48.5 percent year-on-year growth. Will the future AI marketplace return to stable growth, or will it remain volatile?

How a Digital-First CEO Leads Transformation

Some leaders reject the notion that "wait and see" is the best response to disruptive change. Savvy senior executives are already driving digital business transformation throughout their organization in an effort to gain a bold strategic advantage. According to the latest market study by International Data Corp (IDC), Digital-First CEOs plan to drive at least half of their income from digital business products, services, and experiences by 2027 -- that's ahead of the market average of 39 percent. Driven by their response to the COVID-19 pandemic, these business leaders have changed how they think about the relationship between business and technology, and how they approach the next digital transformation era -- from scaling digital technology to guiding a viable digital business. Digital Business Market Development IDC defines digital business as value creation based on technology, which entails: 1) Automated customer-facing processes and internal operations; 2) Provision

Digital Solutions for Industrial & Manufacturing Firms

Executive leaders of fast-moving consumer goods (FMCG) are seeking guidance on how to apply new business technology in their manufacturing operations. CIOs and CTOs are tasked with gaining insight into the best solutions for digital transformation. ABI Research evaluated the impact politics, regulation, the economy, supply chain, ESG, and technology are having on FMCG, pharma, producers of steel, chemicals, pulp and paper -- as well as the mining and oil & gas sectors. Digital Transformation Market Development "Our assessment found that the FMCG sector is under pressure from all sides," says Michael Larner, industrial & manufacturing research director at ABI Research . Securing raw materials is challenging considering lockdowns in China and limited grain supplies from Ukraine. Supply shocks are raising input costs, and operating costs are rising with higher energy costs coupled with the pressure to pay higher wages and work sustainably. "We all hoped that with th
