Google's Powerline Play

Google (Nasdaq: GOOG) may rely on broadband over power line (BPL) technology to augment its Mountain View, Calif., WiFi network in the face of alleged interference problems, one analyst says.

Google outfitted Mountain View with free WiFi last year (See Mountain View Gets Free Access and Google Takes WiFi Plan to the 'Hood.) But interference with other WiFi networks is creating "security and containability issues," Global Equities Research analyst Trip Chowdhry writes in a report issued earlier this month.

So, apparently, it's BPL to the rescue.

"Contacts feel Google WiFi network interference can be solved when Google rolls out DS2-based, 200 Mbit/s powerline home networking technology," Chowdhry writes.

The company Chowdhry refers to -- Design of Systems on Silicon (DS2) , of Spain -- sells BPL gear, including dongles (the adapters that plug into the wall), based on Universal Powerline Association high speed powerline networking standards. (See Pirelli Uses DS2 for Powerline.)

So when might Google make a decision on the technology? "Probably within next 12 to 18 months," Chowdhry tells Light Reading.

Another source tells Light Reading that Google is in the "talking and exploring" phase with powerline home networking.

Google spokesman Brian O'Shaughnessy called any engagement with DS2 "rumor" and declined further comment.

In fact, Google isn't even admitting to the interference problem, despite several reports to the contrary from Mountain View users. (See WiFi Outlook Cloudy in Mountain View.) "You stated that users were having interference problems in their homes; I would take issue with that," O'Shaunessy says. "We haven't seen any evidence of that.”

Google has shown an interest in BPL in the past. The company invested in the BPL vendor Current Communications Group LLC in July 2005. But Current doesn't make home networking gear; its technology is focused on helping electric utilities deliver broadband service over the public power grid. (See Current Comms Raises $130M.)

Google has a foot in home networking as well. In November 2006, it invested in the startup Meraki, which makes in-home wireless mesh routers intended to extend muni WiFi signal into apartment buildings and homes. (See Google Invests in Indoor Mesh.)

Chowdhry believes Google has spent between $1.2 million and $1.5 million on WiFi equipment for Mountain View. The city covers about 12 square miles and is home to around 72,000 people.

re: Google's Powerline Play

BPL does not work ... ask the many, many, many utilities that tried pilots ... it does not work.

Current Link still advertises that BPL is their main stay but the truth is they have converted themselves due to sunken costs to monitoring the power grid and reading meters remotely. They are making lemonaid out of lemons (BPL). Current Link is building out gobs of fiber to overlay the power grid -- if the power grid could support BPL they would not be building out the fiber!!!!!!!!!!

GOOGLE which does nothing but evil deserves BPL ... go get it GOOGLE!

Trip Chowdhry is a clear example of why people in his profession are called anal-ysts. He clearly has no contacts inside google and is talking out of the wrong orifice.

re: Google's Powerline Play
Google would be foolish to put any money into BPL technology given the well documented radio frequency interference problems.

re: Google's Powerline Play
Well everyone ignores the wireless issues and pushes forward in these "mesh" projects. I see no reason why they should not waste time/money on BPL as well.

When your marketing dept has more say than engineers in network design, you get what you deserve!

Broadband speeds are ramping up across Europe as the continent, at its own pace, follows North America towards a gigabit society. But there are many steps to take on the road to gigabit broadband availability and a number of technology options that can meet the various requirements of Europe’s high-speed fixed broadband network operators. During this radio show we will look at some of the catalysts for broadband network investments and examine the menu of technology options on offer, including vectoring and for copper plant evolution and the various deployment possibilities for FTTH/B.
