Atheros has expertise in wifi, Bluetooth, GPS, Ethernet, power saving and peer to peer connectivity

US chip giant Qualcomm on Wednesday agreed to snap up Atheros Communications, a wired and wireless networking technology vendor, for a total of $3.1bn in cash.

The Big Q said it will use the acquisition to expand its own stable of technologies and platforms beyond the cellular market and into the consumer electronics and enterprise spaces. Atheros has expertise in wifi, Bluetooth, GPS, Ethernet, power saving and peer to peer connectivity.

“It is Qualcomm’s strategy to continually integrate additional technologies into mobile devices to make them the primary way that people communicate, compute and access content.  This acquisition is a natural extension of that strategy into other types of devices,” said Paul Jacobs, chairman and CEO of Qualcomm.  “The combination of Qualcomm and Atheros is intended to accelerate this opportunity by utilising best-in-class products for communications, computing and consumer electronics to broaden existing customer relationships and expand access to new partners and distribution channels.”

Atheros president and CEO, Craig Barratt, is expected to join Qualcomm as president of Qualcomm Networking & Connectivity, when the transaction closes in the first half of this year.

Video over power lines closer to reality

The HomeGrid Forum, a newly established trade group tasked with driving the ITU’s home networking specification, said this week that the standard is now stable enough to be adopted by silicon manufacturers.

HomeGrid focuses on the development of a standard that will allow home networking over coax, power lines and phone lines – an ambitious project that has been decades in the making.

With connectivity seemingly moving in a wireless direction these days, it all sounds a bit retro – HomeGrid isn’t even talking about in-building networking over next generation fixed technologies like fibre, it’s talking about decades old, cloth covered power cables in crumbling British Victorian houses.

Yet HomeGrid spokesman David Thorne, who is also chief broadband and access strategist for BT, is surprisingly candid about the technology. “We’re not out to replace wifi,” he said at a meeting at BT’s central London headquarters this week. “This is a complementary technology to wireless. Wifi does a good enough job for connecting computers to the internet, but a hybrid system of fixed and wireless will be needed for higher bandwidth applications.

“If you’re not planning on moving video around the home, then you don’t need to consider this,” he said. “But if you are, then you can send it over any old wires.”

At the recent ITU conference in Geneva, the HomeGrid Forum announced the ratification of key components of the G.hn specification for networking over power lines. Although the technology has been in development for many years, it has been hindered by technical immaturity and fragmentation, resulting in a number of proprietary technologies being pushed by various vendors.

Fortunately, an accord was reached at the ITU event which allows coexistence between the G.hn specification and other wireline networking standards, resulting in a unified global standard for networking of content to devices over any wire – coax cable, phone line, and power line.

According to Thorne, this standard is now stable enough to allow silicon manufacturers to bring products to market. The BT strategist expects the technology to be built into consumer electronics such as set top boxes, multimedia systems and home security systems, and will allow content to be piped around the house to other devices plugged into the mains.

And in an age when consumers are faced with a plethora of new home networking technologies, such as femtocells, media centres and FMC, Thorne expects networking over power lines to be an easy sell. “It’s simple to market to the consumer,” he said, explaining that a user would plug one G.hn-enabled device into the mains in one room, and another into the mains in another room and they would communicate with each other.

In related news, another forum, the Wi-Fi Alliance on Wednesday announced a new specification that will allow wireless-enabled devices to communicate with each other in a similar fashion to the way Bluetooth already allows.

The specification, code named ‘Wi-Fi peer-to-peer,’ can be implemented in any wifi device, from mobile phones, cameras, printers, and notebook computers, to keyboards and headphones, and will allow said devices to more effectively connect in order to print, share and display.

Certified devices, which are expected to appear from 2010, will be branded Wi-Fi Direct, the alliance said.
