802.11n Wi-Fi imperiled by patent problems?


When last we visited the upcoming 802.11n standard for Wi-Fi, the IEEE was working slowly on the official standard while manufacturers were rushing out and certifying Draft 2 compatible products. Now The Register reports that there’s a spanner in the gears since some outstanding patents actually threaten the IEEE adoptability of the 802.11n standard.

First 802.11n Draft 2.0 products certified


As I mentioned in May, the program for “Wi-Fi CERTIFIED 802.11n Draft 2.0″ products was to get started in June, and last Friday it bore first fruit as the first router and adapter were certified:

802.11n Draft 2 logo program due in June


Even though the 802.11n specification appears to be 2 years from ratification, the Wi-Fi Alliance today announced they are starting a logo program for “pre-n” Wi-Fi networking gear:

Wi-Fi CERTIFIED 802.11n draft 2.0 products sporting an eye-catching new logo will soon reach store shelves, as the Wi-Fi Alliance certification program nears its late June launch. The Alliance today unveiled a re-designed consumer logo for Wi-Fi CERTIFIED 802.11n Draft 2.0 products, and announced the products and reference designs that will comprise its test bed for interoperability certification.

The practicalities of the matter are that while there is a lot of bureaucratic jockeying going on over the details of the final 802.11 n spec, Draft 2.0 is close enough that presumably all logo certified gear will be upgradeable to the final standard with just a firmware upgrade.

Since there are no Draft 2.0 products shipping yet, a natural question is whether any pre-n products currently available will be upgradeable to Draft 2? The answer is “that depends” and to check with the manufacturer, although there is a good chance that any Draft 1 pre-n gear will be firmware upgradeable. The vendors should be very upfront since this kind of thing kills sales dead until the information is forthcoming.

On the other hand, if you prefer to avoid the excitement of a firmware upgrade, hold off on any new Wi-Fi gear until June and look for the following logo for the certified 802.11n Draft 2.0 products:

Airgo chipset to provide Wi-Fi IPTV


Marguerite Reardon at ZDNet:

Airgo Networks, which makes Wi-Fi chips, announced Tuesday that Caton Overseas and STMicroelectronics will use its latest generation of wireless technology to distribute video over Wi-Fi links throughout the home. Caton is a Chinese maker of set-top boxes for satellite and cable TV providers in Asia and Europe, and STMicroelectronics provides chips to set-top box manufacturers such as Siemens and Cisco Systems’ Scientific Atlanta.

Airgo has already been supplying wireless routing companies such as Linksys with high-performing Wi-Fi chips using a technology called MIMO or multiple input, multiple output, which improves Wi-Fi’s range and throughput. MIMO is currently the primary basis for next-generation Wi-Fi standard 802.11n.

Now Airgo says it has tweaked its MIMO technology to improve the throughput, range and reliability of the signal enough to deliver high-quality video. Airgo’s next-generation chips, called True MIMO Gen3, provided transmission speeds up to 240mbps when tested in Airgo’s 6,000-square-foot model home, said Dave Borison, director of marketing for Airgo. This speed is enough to transmit three high-definition TV channels, he said.

The good news is that you don’t have to run wires, but I wonder about interference if everyone has a similar setup. How many folks in your neighborhood use anything but the default channel for their Wi-Fi setups?

Compromise Wi-Fi MIMO standard coming?


You may recall that I have previously mentioned ([1], [2]) the ongoing battle over the next Wi-Fi standard. Now it looks like a compromise has been reached:

An industry group seeking common ground on the emerging IEEE 802.11n high-speed wireless LAN specification has agreed on a compromise proposal that may form the basis of a final standard.

The joint proposal group, which includes backers of all the major factions in the fight over how to boost the speed and range of wireless LANs, late Wednesday [Jan. 11 - ed.] approved a proposal by a unanimous online vote with two abstentions, according to Bill McFarland, chief technology officer at Atheros Communications, a semiconductor vendor that belongs to the group.

The IEEE is expected to formally accept the proposal in a meeting this week, but it likely won’t be formally adopted for about a year. The good news is that won’t slow down the vendors:

But partly because the standards process has taken so long and vendors have gained experience with the new technology, there will probably be pre-standard products on the market in the middle of this year that are mostly interoperable and can be upgraded to the final standard via software or firmware upgrade.

The advantages are 802.11n, or MIMO as it is often called, are greater range and faster speed.

Skype partners roll out the hardware at CES


The International Consumer Electronics Show starts Thursday, but to get ahead of the cloud of press releases some vendors have “launched” early and Skype is no exception. Their big news isn’t with Skype’s base VoIP service, but with the hardware partners they have signed up - Alliances with Creative, D-Link, IPEVO, Kodak, Netgear, Panasonic, and VTech Illustrate Skype Market Leadership.

The emphasis seems to be mostly on integrating Skype with normal phone equipment:

VTech USB7100 Phone – availability of the previously announced VTech USB phone, expandable with up to four handsets and allows users to view their online contacts. It’s dual line for both Skype and regular telephone service and has cordless handsets.

D-Link Skype USB Phone Adapter (DPH-50U) – a Skype phone adapter that enables the use of Skype on a traditional phone.

The D-Link Skype USB phone adapter (DPH-50U) lets users accept both regular telephone and Skype calls from the same phone for added flexibility. When consumers are talking on a traditional telephone line and receive an incoming Skype call, they can easily switch lines to take the Skype call or vice versa, just like a typical call-waiting feature.

Conference calls can also be connected between ordinary telephone lines and Skype. For added convenience, the D-Link Skype USB phone adapter includes a lighted display to indicate whether an incoming call is from a traditional telephone or from a Skype user.

Panasonic – a cordless telephone product that interfaces directly with Skype, allowing users to make and receive Skype calls and traditional calls using the same device

As its initial offering, Panasonic plans to launch a Skype compatible cordless telephone product that will enable select Panasonic cordless telephones to interface directly with Skype. With the new product, consumers will be able to make and receive Skype and traditional calls using the same Panasonic cordless phone.

There are also the more usual Skype phones:

Creative Skype Internet PhonePLUS – a standalone phone that enables anyone to make free Skype calls over the Internet without a PC connection. (That’s all the details so far.)

IPEVO Fly-1 Cordless Handset and Xing Speakerphone – PC and Mac compatible IPEVO Fly-1 cordless Skype USB handset and an IPEVO Xing Skype USB speakerphone.

FLY.1 is a USB cordless handset with a speakerphone that works exclusively with Skype. It is designed to integrate the Skype experience with the operational familiarity of a telephone. The cordless handset offers portability and enables communication using Skype away from the user’s PC or Macintosh through a wireless USB dock.

The Xing USB speakerphone is the first device from IPEVO designed for business teleconferencing using Skype. The cross-shaped device is designed to sit atop a desk or boardroom table allowing for multi-user participation through four separate speakers. The device is not restricted by a phone jack, allowing for increased mobility and user convenience.

And some items that are hard to categorize:

NETGEAR – a new communications device to be unveiled at CES on Wednesday, January 4th and no details have been revealed.

KODAK Photo Voice – a beta version of the first Skype certified online photo sharing service.

Eastman Kodak Company and Skype™, the global Internet communications company, announce the availability of the latest innovation in digital storytelling ― KODAK Photo Voice ― that combines live voice and online photo sharing. The beta version of KODAK Photo Voice, the first Skype certified online photo sharing experience, is now available as a free download at www.kodakgallery.com/photovoice.

“Today’s families and social networks are scattered around the globe. Staying connected through photo sharing remains an important element in maintaining closer personal relationships,” said Sandra Morris, general manager of Consumer Imaging Services at Kodak. “Traditional social gatherings that once took place around the radio, television or telephone are now happening around the computer, mobile phone or camera. KODAK Photo Voice marks the next step in this evolution.”

KODAK Photo Voice is a brand new way to relive memories, empowering two people to simultaneously view a customized slideshow, and to reminisce and react to each picture. Imagine if Grandma could see pictures from her grandson’s first day at school while he narrates every moment of the experience over Skype. Perhaps an old roommate could share detailed photos and recount stories of his new life in London, as his friend back home in California reacts to each picture.

Sorry, but this last one seems like a solution in search of a problem, but it is free.

Update 1/04: They had some trouble with the demo, but Netgear announced a Skype WiFi phone:

The NETGEAR WiFi phone will make mobile Internet telephony a reality for Skype users. Unlike other devices that must connect with a PC, NETGEAR’s Skype WiFi phone will work wherever a consumer is connected to a wireless Internet access point — be that in a home, office, cafe, open public hotspot, or any open municipal wireless access point being deployed worldwide.

The NETGEAR phone is pre-loaded with Skype’s software, ready out-of-the-box to use with a wireless network. All a user needs to do after turning on the phone is enter a Skype username and password. The Skype software pulls up the user’s full contact list, displays the connection status on the phone screen, and allows the consumer to connect to any other Skype user for free. The phone will also allow users to connect to non-Skype users with the SkypeOut™ feature. More information on NETGEAR’s Skype WiFi phone, including pricing and availability, is planned for the first quarter of 2006.

In addition to the Skype Wifi phone, NETGEAR and Skype also announced that the NETGEAR RangeMax Wireless Router (WPN824) with Smart MIMO technology, a 2006 CES Innovations Design and Engineering Award honoree and the industry’s #1 selling MIMO-G product, will be equipped to optimize Skype.

The phone seems similar to the Accton Skype phone and the UTStarcom Vonage phone I’ve mentioned previously.
