Direct Connect, Here We Come! Standards Compliance Testing for Wi-Fi Direct

For times when Internet hotspots aren’t available, the Wi-Fi Alliance is now offering certification for a new way to connect: Wi-Fi Direct™. First demonstrated at CES 2010, Wi-Fi Direct enables devices to connect directly without relying on a network access point. Furthermore, Wi-Fi Direct allows users to share data and sync at the same speeds as traditional Wi-Fi networks – as fast as 250Mbps – and at ranges of up to 200 meters. The new certification program is designed to verify interoperability, and certified products will be able to connect with older Wi-Fi products already in use.

The Wi-Fi Alliance’s video, above, shows the many ways devices can take advantage of Wi-Fi Direct.

With several industry leaders – including Intel, Cisco and Apple – backing the technology, Wi-Fi Direct is expected to be adopted across a wide range of products, including cameras, laptops, smart phones, tables, printers and even home applications such as digital picture frames.

Allion is excited to announce our new role as an authorized test lab for Wi-Fi Direct. We have a long history of providing standards compliance testing services for manufacturers working with IEEE 802.11 benchmarks, and we are excited to begin Wi-Fi logo testing for Wi-Fi Direct.

“Allion is capable of verifying all Wi-Fi standards such as Wi-Fi 802.11 a/b/g/n and the latest Wi-Fi Direct,” said James Ou, director of Allion’s engineering service division in a recent press release. “Our goal is make the program simple for our customers and to accelerate time to market.”

Web-Connected TVs Set for Takeoff

Consumers are more connected than ever, with Wi-Fi enabled laptops and cell phones providing virtually seamless Internet access. Now analysts are saying that the next wave of networked-enabled devices will be your televisions.

According to a new report by DisplaySearch, sales of Internet-enabled TVs are expected to grow by more than 200 percent over the next four years. The Quarterly TV Design and Features Report forecasts that more than 118 million Internet-connected TVs will ship in 2014, a significant increase from the 15 million shipped in 2009. The growth of network-enabled TVs is expected to occur in conjunction with 3-D TV adoption.

“It’s an exciting time for the connected TV sector,” said Paul Gray, director of European TV research for DisplaySearch, in the report. “It’s a battleground where TV set makers, Internet video companies, free-to-air broadcasters, pay-TV and the IT industry are all rushing to stake their claims. IPTV [Internet Protocol Television] is moving from being a technology to becoming recognizable service offerings.”

The burgeoning IPTV industry offers plenty of options for designers looking to take advantage of new market opportunities. New service platforms are being developed, with connectivity levels ranging from app-enabled TVs – which allow users limited Internet services – to “Smart TVs” offering full browsing capabilities and sophisticated user interfaces. Meanwhile, broadcasters are launching their own standards and portals such as hbb.TV and YouView.

The demand for connected TVs follows the industry movement we have seen here at Allion. We’ve witnessed products become increasingly connected, with our product validation services enabling us to stay at the forefront of these emerging markets and trends.

Consumers Eager for Wireless Charging, Despite Barriers

Recently we wrote about the growing market opportunity for wireless charging devices. These products will allow customers to charge mobile devices –such as cell phones, laptops, MP3 players and more – simply by having them touching or within proximity of a shared charging station. Such devices would eliminate the plethora of cords required to power today’s digital gadgets. Furthermore, such wireless chargers could be integrated seamlessly into furniture and cars.

Consumers are more than eager for these types of products to enter the market; in fact recent In-Stat research found that consumers are becoming impatient for this technology to mature. With 44 percent of survey respondents calling current charging solutions an “annoyance” and up to 40 percent willing to pay $50 dollars more for a wireless charging device, In-Stat projects that that this market will reach $4.3 billion in total market revenue by 2014.

However, technological barriers are preventing immediate market growth. The variety of digital devices and brands makes interoperability testing a problem. Furthermore, competing technologies could foster incompatibility. Needless to say, consumers will not want to buy multiple wireless chargers for different devices. Without standardization, it could be difficult to achieve widespread adoption of wireless charging technologies.

Despite these obstacles, the wireless charging market has such great potential and natural consumer demand that we expect it to move forward. Manufacturers will not want to miss this opportunity to provide consumers with cutting-edge charging technologies. Allion will continue to provide more information as it becomes available, and we look forward to testing and validating this new wave of devices.

Happy Birthday, Wi-Fi n!

One year ago the Wi-Fi Alliance launched its Wi-Fi CERTIFIED n compliance program, creating a certification process and logo for the IEEE 802.11n standard. Within that time frame, more than 1,100 products – from cellphones to TVs to enterprise-grade infrastructure devices – have been certified, and consumers have drastically changed the way they interact with electronics.

As we celebrate the anniversary of the certification, here are a few of the landmarks Wi-Fi CERTIFIED n has made in the last year:

• 127 phones have passed certification testing, reportedly accounting for 20 percent of handsets certified in the last 12 months.
• 251 consumer electronics products have been certified, including digital audio systems, gaming devices and displays.
• 441 of these certified products are dual-band products – capable of operating in both 2.4GHz and 5GHz frequency bands – and 143 products can support 2.4 GHz and 5GHz operation concurrently.157 enterprise-grade infrastructure devices and 115 enterprise-grade access points have been certified as enterprise networking vendors respond to growing demand for networking solutions.

This increase in connectivity has made a huge impact on the indus

try in short period of time. As a recent In-Stat report stated, Wi-Fi has achieved “ubiquity, a term often used but seldom realized in technology market-speak.” At Allion, we’ve seen this growth take place first hand, with our Wi-Fi Logo Testing Program – which includes 802.11n testing –

allowing us to support the Certified Wi-Fi rollout for both consumer and enterprise devices alike.

“It’s clear that Wi-Fi’s integration into virtually all areas of the consumer electronics spectrum continues to expand,” said Phil Solis, research

director, ABI Research in a recent Wi-Fi Alliance release. “At the heart of this growth is Wi-Fi CERTIFIED n, which will continue to deliver the

advanced performance these devices require, now and well into the future.”

So happy birthday, Wi-Fi CERTIFIED n! We’re excited to see what the next 12 months may bring.

PCIe 3.0 Here at Last: Welcome to the Future of PCI Testing

The long-awaited PCI Express (PCIe) 3.0 specification standard is set to arrive in November, opening the doors for a new wave of products featuring faster interconnect speeds. Consumer products using the PCIe 3.0 are expected to arrive as early as the second half of next year.

The PCI Express 3.0 specification will define

operating speeds of up to 8 gigatransfers per second (GTps), delivering a significant boost from the 5 GTbps defined by PCIe 2.0. It also offers 128- and 130-bit encoding schemes, improving efficiency from the current 8- and 10-bit format and leaving nearly the entire bandwidth free for signal processing. Other new features include Dynamic Feedback Equalization (DFE), a sophisticated technique in electrical signaling designed to maintain signal integrity. The updated specification is expected to aid the growth of faster PCIe switches, 40Gbit Ethernet chips, high-end graphics cards, and solid-state drives (SSDs). PCIe 3.0 is fully backward compatible with previous generations of PCI technology. The chart below shows how the new standard compares to older PCI testing specifications.

PCI-SIG, the industry organization chartered to develop and manage the PCI standard, will issue tools to validate designs and start will launch interoperability testing workshops in mid-2011, with specification testing for PCIe 3.0 expected to be completed late next year. We will keep you posted on developments about this exciting specification update as they become available.

Wireless Charging: A Whole New Market

The average consumer uses a variety of electronic devices daily – cell phones, laptops, MP3 players, headsets, etc. – all of which require different chargers for keeping gadgets at full battery. In a market driven by mobility and convenience, charging solutions have failed to evolve with the rest of the industry. Not surprisingly, consumers have become annoyed with all these different, often proprietary, cords and connectors. According to recent surveys by In-Stat, approximately 44 percent of respondents found that “current mobile charging solutions are an annoyance,” and “up to 40 percent are willing to pay $50 more for a wireless charging solution.”

This is creating a new market opportunity for wireless charging systems. According to a recent study by In-Stat, the market for wireless charging systems will reach $4.3 billion in total revenue by 2010. These products can charge mobile devices, from phones to PCs to handsets, simply by having the devices touching or within the proximity of a charging station. These charging solutions can often be hidden, or at least seamlessly integrated, into furniture or automobiles; more than two thirds of the integrated charging solutions are expected to be in cars.

“Despite the long history of the various technologies, we are really just now beginning to see the true market potential for wireless charging solutions,” says Jim McGregor, In-Stat’s chief technology strategist. “Like many other technology markets, it will start with add-on and third-party solutions. Eventually solutions will be integrated into many mobile electronics as the costs decrease and the demand increases. While still a fraction of the overall mobile device segment, wireless charging is just beginning to hit its stride in the market.”

As with all technologies designed to service a variety of devices from different vendors, interoperability will be a primary challenge for product designers. Wireless products also face the added difficulty of avoiding interference with other wireless devices. Allion Test Labs will continue to track this industry trend and provide insight for manufacturers.
