An Overview of How WiGig Technology Works

The rise of high-definition TVs and other digital multimedia devices brings both excitement and challenges. While consumers now have an abundance of entertainment options, these innovations come with a growing demand for faster data transfers. For instance, HDTV requires speeds of about 3Gbps (gigabits per second), which typically necessitates a high-speed wired connection.

Why rely on wires? Although wireless LAN technologies are sufficient for tasks like web browsing, WiFi can't handle the demands of activities such as HDTV viewing or video streaming. As a result, many homeowners and businesses turn to wired networks, leading to a clutter of costly cables.

In May 2009, a new collective known as the Wireless Gigabit Alliance revealed its mission to develop a high-speed wireless standard called WiGig. This cutting-edge technology is still in its early stages, with its official specifications expected by the end of 2009.

While the full details are yet to be revealed, we already know enough to imagine some exciting possibilities. WiGig will primarily serve within a single room, providing fast wireless connectivity for home entertainment devices. It promises ultra-fast data transfers and smooth streaming, along with wireless connections for laptops, cameras, and more.

How fast is fast? WiGig is anticipated to be nearly 10 times faster than current WiFi speeds, potentially enabling the transfer of a 25GB Blu-ray disc in under a minute. With this lightning speed, a full DVD could be transferred in just 15 seconds. Say goodbye to buffering video clips and painfully slow data transfers.

Exploring WiGig's Bright Future

Though WiGig's final specifications are still pending, we already have a strong understanding of how it will operate. Manufacturers are also planning how to incorporate WiGig into their upcoming products.

WiGig has the potential to connect a wide array of computing, entertainment, and communication devices, such as stereos, PCs, PDAs, and more. It could simplify video-on-demand and the delivery of archived content across TVs, computers, and other devices. WiGig may also be the ideal solution for gaming on HDTVs or transferring videos from a wireless camcorder to a TV or computer.

WiGig-enabled devices will operate on a 60GHz frequency, an unlicensed spectrum that is largely unused by current technologies. This frequency was chosen for its availability and its ability to achieve ultra-fast data transfer rates. Additionally, WiGig's low latency ensures minimal delay, preventing lag or interruptions in HD video or online gaming experiences.

Signals within this frequency band don't travel far. Oxygen easily absorbs 60GHz signals, causing them to dissipate quickly within a short range. Walls further hinder 60GHz signals, which significantly limits WiGig's effective range. This means WiGig’s coverage will be restricted to approximately 30 feet (about 9.1 meters), with performance dropping substantially beyond 15 feet (4.6 meters). This limitation is actually advantageous for WiGig-powered devices, as it prevents interference with neighboring networks or other WiGig setups in your home.

It’s common for new technology standards to be introduced, only to fail due to lack of industry support. However, WiGig is well-positioned for success with significant backing from its Alliance partners, including prominent companies like Microsoft, Panasonic, Dell, Nokia, and others.

Exploring More WiGig Applications and Competitors

As mentioned earlier, WiGig signals aren't designed for long-range travel. They work best within a single room, where they can bounce off walls to reach their destination. Some home layouts may allow the signal to extend into nearby rooms, but in most cases, WiGig will have a one-room range.

WiGig devices will deliver data transfer speeds of at least 1Gbps at 10 meters (32.8 feet), with theoretical maximum speeds reaching up to 6Gbps. Speed performance will vary by device: handheld, battery-powered devices will operate closer to the 1Gbps mark, while devices plugged into electrical outlets will reach closer to the 6Gbps ceiling.

The final WiGig specifications are expected to be ready by sometime in 2009. Mark Grodzinsky, chairman of the marketing working group for the WiGig Alliance, stated, "When we launched the organization, we messaged that the specification would be completed by the end of the year, and we are still tracking well to that goal."

Once the WiGig specifications are finalized, manufacturers can start producing WiGig products. If everything goes as planned, these manufacturers may begin creating and selling products in 2010, although some experts believe this timeline might be overly optimistic.

Meanwhile, WiGig proponents will closely monitor competing technologies that could overlap with or challenge their developing standard. They will pay particular attention to WirelessHD, WiMax, WHDi (Wireless Home Digital Interface), and WiFi standards such as 802.11AD and 802.11n.

WirelessHD is another 60GHz technology, specifically designed to facilitate video transfer between TV set-top boxes and Blu-ray players, with a maximum speed of about 4Gbps. Although WirelessHD products are available now, they are not heavily promoted by the largest tech companies.

WiMax, based on the 802.16 standard, has long promised to deliver city-wide internet access for both stationary and mobile users. Despite the technology's age, it is only now being deployed in certain cities. WiMax's key advantage is its broad coverage area, with an ideal range of up to 30 miles (48.3 kilometers). It offers speeds of about 70Mbps, which, while fast, still falls short of WiGig’s capabilities for demanding multimedia tasks.

WHDI is a 5GHz specification designed for similar purposes but utilizes technology akin to WiFi, with a maximum speed of around 3Gbps. Supporters of WHDi believe its whole-house range could seamlessly complement WiGig's shorter range and high bandwidth. Similarly, WiFi standards like 802.11 might end up working in conjunction with WiGig. Instead of being direct competitors, future devices may feature both WiFi for extended range and WiGig for faster data transfer when users are near an access point.

Will WiGig become the next groundbreaking advancement in wireless networking? It's too soon to say, but homeowners and businesses reliant on high-speed connections are hoping WiGig will help them escape the tangle of wires and bring their multimedia aspirations to life.
