Secure HD Video & Wireless Home Networks

Wireless communication within the home, whether for computer data, audio, or telephony, is becoming an established fact in much of the industrialized world.

The next logical step is to stream video. But the exponentially greater amount of data involved -- particularly for high-definition TV -- introduces a higher order of difficulty, and questions remain about whether wireless video will ever become more than a niche market.

"How popular will wireless home video distribution become?" asks ABI Research principal analyst Steve Wilson. "It's the very early days for this market, so it's hard to tell for sure. What is clear is that among the connectivity technologies competing in this space, Wi-Fi (802.11n) and wireless HDMI (UWB) are closest to offering practical solutions."

Consumers might want a wireless video distribution solution, but most will not pay a premium for it. So initial interest will come from two groups -- tech-savvy early adopters at the high end of the home theater market, and those using the services of custom audiovisual installers.

Paradoxically, building a large custom home entertainment system wirelessly could reduce installation costs by eliminating the need to run cables through and within walls. While Wi-Fi formats suffice for compressed video, the HDMI link between consumer electronics devices and the TV carries relatively uncompressed data.

In another paradox, the Hollywood studios consider wireless uncompressed HD video more secure: the vast amounts of data make storage difficult and the shorter range of HDMI radio signals makes snarfing -- the theft of content from a nearby network -- much more difficult compared to compressed data transmissions.

The challenge is to create equipment that can handle these huge amounts of information at a reasonable price.

"The cost must be reduced," says Wilson, "Vendors are hard at work developing products that will provide better quality at less expense. Especially for HD, today's approaches may not be economically viable, but there are novel design approaches in the pipeline that may spark market growth."

Mobility-as-a-Service Creates Disruptive Travel Options

Building on significant advances in big data, analytics, and the Internet of Things (IoT), more innovative transit service offerings aim to increase public transport ridership and reduce emissions or congestion within metropolitan areas. By providing these services through smartphone apps, the transit services also significantly increase user convenience, providing information on different human mobility offerings -- including public transport, ridesharing, and autonomous vehicles. Mobility-as-a-Service Market Development According to the latest market study by Juniper Research, Mobility-as-a-Service (MaaS) subscribers will generate $53 billion in revenue for MaaS platform providers by 2027 -- that's rising from $5.3 billion in 2021. Let's start with a basic definition. MaaS is the provision of multi-modal end-to-end travel services through single platforms, by which users can determine an optimal route and price. The study identified a monthly subscription model as key to incr

Hybrid Work: How to Enhance Employee Productivity

When you hire qualified talent for a key role and trust them to perform, you'll likely achieve the best outcome. Skilled and experienced people will deliver results, regardless of the challenges. That's a key lesson learned from the pandemic experience as most knowledge workers were asked to work from their homes. However, some resist returning to an open-plan office. It's unacceptable. Meanwhile, forward-thinking leaders decided a "return to normal" is undesirable, and in hindsight, everyone should aspire to be more accomodating than before. Therefore, location flexibility is okay. Hybrid Workforce Market Development How will people adapt to these changes? They'll apply the modern IT tools at their disposal. They'll learn new skills and thrive. Nearly 80 percent of employees are now successfully using online collaboration tools for work in 2021 -- that's up from just over half of workers in 2019, according to the latest market study by Gartner. This g

Robocall Mitigation Solutions to Halt Criminal Threats

If you answer the phone and hear a recorded message instead of a live person, it's likely a robocall. A robocall is a phone call that uses a computerized autodialer to deliver a pre-recorded message. In 2020, the U.S. Federal Trade Commission (FTC) received 2.8 million consumer complaints about robocalls. Offering solutions to robocalling and associated fraudulent business practices, computerized mitigation platforms are an integral part of the solution. Platforms that are focused on actionable systems to disrupt unsolicited and potentially criminal phone calls help telecom service providers and industry regulators. Issues of whether one-size-fits-all developments are sufficient to be effective across the spectrum need to be addressed, and whether a single telecom network operator working unilaterally with a third-party platform could compromise desired or mandatory industry-wide standards.
