WiGig, Wi-Fi Join Forces

WiGig, Wi-Fi Join ForcesWireless Week is reporting that the Wireless Gigabit Alliance (WiGig) and the Wi-Fi Alliance have joined forces. According to the article, the Wi-Fi Alliance and WiGig Alliance have collaborated for over two years on the WiGig Alliance’s work to develop an interoperability certification for 60GHz products.

Wi-Fi Alliance logoWi-Fi Alliance President and CEO Edgar Figueroa said in a statement that the 60GHz technology has been an important highlight in the Wi-Fi Alliance’s certification roadmap for some time. “Combining the expertise of Wi-Fi Alliance and WiGig Alliance will deliver a terrific user experience with 60 GHz solutions, and will help ensure that a full range of interoperable WiGig solutions reach the market as quickly as possible,” Mr. Figueroa said in a statement.

WiGig operates in the unlicensed 60 MHz band and offers short-range multi-gigabit connections with speeds up to 7 Gbps. FierceBroadbandWireless reports that early applications will include ultrabooks and peripherals. WiGig offers short-range multi-gigabit connections for applications ranging from high-definition WiGig Display Extensions (WDE) to peripheral connectivity and I/O cable replacement such as WiGig Serial Extension (WSE), WiGig Bus Extension (WBE), and WiGig SDIO Extension (WDS). Tablets will then include the technology, primarily for media streaming, and smartphones will drive more widespread WiGig adoption from 2015 on according to ABI Research.

Its major limitation is the extremely high 60 GHz frequencies it uses, which limits its connections to near-line-of-sight within a single room. Signals in the 57–64 GHz region are subject to a resonance of the oxygen molecule and are severely attenuated.

WiGig logoEarly 60 GHz implementations based on the WiGig specifications are entering the market now, and ABI Research forecasts that by 2016, annual shipments of devices with both Wi-Fi and WiGig technology will reach 1.8 billion units.

Multi-Gigabit Wireless by 2012

Multi-Gigabit Wireless by 2012A January 26, 2009, ScienceDaily article describes a new CMOS chip capable of transmitting 60 GHz digital RF signals. The new chip enables rapid wireless transfer of a high-definition movie from a PC to a cell phone. It was developed at the Georgia Institute of Technology‘s Georgia Electronic Design Center (GEDC).

There are many potential 60 GHz applications. Some applications are virtually wireless desktop computers, data centers, and wireless home DVD systems. The 60 GHz application would allow in-store kiosks that transfer movies to handheld devices in seconds. It also has the potential to move gigabytes of photos or video from a camera to a PC almost instantly.

Experts believe that this technology could yield high-speed, short-range wireless applications by 2012. According to Joy Laskar, director of the GEDC, “Consumers could see products capable of ultra-fast short-range data transfer within two or three years.” Ann Revell-Pechar, chair of the MIT Enterprise Forum of Atlanta Chapter says “Multi-gigabit wireless technology is widely perceived to bring important new wireless applications to both consumer and IT markets.” Darko Kirovski, senior researcher at Microsoft Research says “Multi-gigabit technology definitely has major promise for new consumer and IT applications.”

Unprecedented short-range wireless speeds

Researchers have already achieved very high data transfer rates that promise unprecedented short-range wireless speeds-15 Gbps at a distance of 1 meter, 10 Gbps at 2 meters, and 5 Gbps at 5 meters.

The GEDC-developed chip is the first 60GHz embedded chip for multimedia multi-gigabit wireless use. According to Ms. Laskar, this new technology “represents the highest level of integration for 60GHz wireless single-chip solutions. It offers the lowest energy per bit transmitted wirelessly at multi-gigabit data rates reported to date.”

Industry group Ecma International recently announced a worldwide standard for radio frequency (RF) technology that makes 60 GHz “multi-gigabit” data transfer possible. The specifications for this technology are expected to be published as an ISO standard in 2009.

Gigabit Wi-Fi

Gigabit Wi-FiDespite the fact that IEEE 802.11n 100Mbps wireless LAN standard has not been approved yet, the IEEE Very High Throughput (VHT) Study Group is about to launch a new project, gigabit Wi-Fi.

The study group is looking at gigabit Wi-Fi in two frequency bands, high-frequency 60GHz for relatively short ranges and under-6GHz for ranges similar to that of today’s WLANs in the 5GHz band, 802.11a and 11n. The IEEE proposal suggests a completion target date of 2013 for the standard. Big wireless players such as Atheros, Broadcom, Intel, Marvell, Motorola, and Nortel are reported to be active in the study group.

In a Network World article, IEEE readies launch of gigabit Wi-Fi project “The basic idea right now, and that’s subject to change, is that the ‘maximum mandatory mode’ on a single link would be [at least] 500Mbps,” says Tushar Moorti, director of systems architecture for chipmaker Broadcom‘s (AVGO) WLAN Business Unit. “But the further requirement is that [an access point] device that supports VHT would be able to sustain multiple links, so the aggregate would be over 1Gbps.”

“It’s the next-generation technology for wireless LAN, in the same sense that 11n was the follow-on to 11a/b/g,” says Broadcom’s Moorti.

According to the proposal, VHT “will allow a corporate or home user to roam from high-throughput dense cells to wider area networks in a seamless manner, while maintaining full support for the installed base security, management, diagnostics, and backbone infrastructure.” VHT will also be backward compatible with the full range of existing and emerging 802.11 standards, such as 11i for security, and 11s for mesh networking.
