If an Android device (phone or tablet) has ever logged on to a particular Wi-Fi network, then Google probably knows the Wi-Fi password. Considering how many Android devices there are, it is likely that Google can access most Wi-Fi passwords worldwide.
Recently IDC reported that 187 million Android phones were shipped in the second quarter of this year. That multiplies out to 748 million phones in 2013, a figure that does not include Android tablets.
Many (probably most) of these Android phones and tablets are phoning home to Google, backing up Wi-Fi passwords along with other assorted settings. And, although they have never said so directly, it is obvious that Google can read the passwords.
Sounds like a James Bond movie.
Android devices have defaulted to coughing up Wi-Fi passwords since version 2.2. And, since the feature is presented as a good thing, most people wouldn’t change it. I suspect that many Android users have never even seen the configuration option controlling this. After all, there are dozens and dozens of system settings to configure.
And, anyone who does run across the setting can not hope to understand the privacy implication. I certainly did not.
In Android 2.3.4, go to Settings, then Privacy. On an HTC device, the option that gives Google your Wi-Fi password is “Back up my settings”. On a Samsung device, the option is called “Back up my data”. The only description is “Back up current settings and application data”. No mention is made of Wi-Fi passwords.
In Android 4.2, go to Settings, then “Backup and reset”. The option is called “Back up my data”. The description says “Back up application data, Wi-Fi passwords, and other settings to Google servers”.
Needless to say “settings” and “application data” are vague terms. A longer explanation of this backup feature in Android 2.3.4 can be found in the Users Guide on page 374:

Inlfight internet service Gogo announced today that it plans to bring new technology to partner airlines in the US that will provide more than 60 Mbps starting with Virgin America flights in the second half of next year. Dubbed “Gogo GTO” or “Ground to Orbit,” the new service offers a 20-fold increase in speeds up from the peak 9.8Mbps delivered through Gogo’s current network.
“Because we are a Silicon Valley-based airline, Virgin America guests expect a fully connected in–flight experience that enables them to remain productive even at 35,000 feet,” said President and CEO of Virgin America David Cush. “We were proud to be the first to offer Gogo’s ATG-4 product last year and we are pleased to be the launch partner for GTO, which will be another leap forward in terms of speed and performance of in–flight Wi-Fi for our guests.”
Gogo will first have to get FAA approval before rolling out next year. But when it does, this is how it will work:
Gogo will be utilizing a Ku antenna developed specifically for receive only functionality. The advantages of using satellite for reception only and Gogo’s ATG Network for the return link are unprecedented. Existing two-way satellite antennas in the commercial aviation market have limited power for transmissions so they don’t interfere with other satellites. This dynamic makes the connection from the aircraft to the ground using two-way satellite an inefficient and expensive return link compared to Gogo’s ATG Network. Gogo’s receive only antenna will be two times more spectrally efficient and half the height of other antennas in the commercial aviation market. The low profile of the antenna will result in much less drag and therefore fuel burn on the aircraft and, ultimately, greater operational efficiencies for airlines.
Technologies being developed to aid in communications between cars may be affected by the Federal Communications Commission’s plan to increase Wi-Fi spectrum.
Bands reserved since 1999 for car-to-car communication may become collateral damage in the FCC’s search for more wireless spectrum, and potentially puts the future of self-driving vehicles at risk.
A letter from automotive trade associations has been sent to FCC Chairman Julius Genachowski in protest of the plans, reports Bloomberg. Parallels were drawn with the LightSquared wireless broadband network proposal, which was at first approved by the FCC, before it was discovered that the signals affected GPS equipment. By opening nearby spectrum to other devices, the possibility of crosstalk or interference with the allocated-to-automotive bands could effectively cause an accident to occur.
The systems currently being developed allows cars at short range to communicate automatically, with data such as speeds, changes in direction, and other important details being transferred between the cars, with the ultimate goal of reducing collisions and vehicular accidents. Currently undergoing testing in Ann Arbor Michigan inside 3,000 vehicles, the technology is said by automakers to cost as little as $100 per vehicle to install, both from new and as an after-market option.
The FCC will be voting on the Wi-Fi proposal on February 20th.
The LifeBot 5 Telemedicine Tool Allows Doctors to Read Data and Send Instructions to Remote Medics in Real-Time
While people such as emergency medical technicians and army medics are true lifesavers, there are times when they could benefit from the resources or expertise of a hospital-based physician. That’s where all-in-one portable telemedicine units like the LifeBot 5 come into play.
Although the device isn’t the only one of its kind, the LifeBot company claims that it is “the world’s smallest, lightest, most advanced portable mobile telemedicine system.”
Weighing in at 15 pounds (6.8 kg), it is able to monitor a patient’s heart rate, blood pressure and body temperature, plus it is capable of performing electrocardiography and ultrasound. It can also transmit video and audio. Future versions may additionally include a defibrillator.
Data is sent securely via 4G, 3G, LTE, WiMax, cellular, Wi-Fi, satellite, and/or data radio connections – the machine automatically selects whatever system(s) work best for the given situation. Remotely-located doctors are then able to view a patient’s vital signs and other data with a delay of only a few seconds, and offer real-time guidance to the on-site medical personnel. Multiple LifeBot units can also communicate with one another, allowing for collaborative efforts on difficult procedures.
The original version of the device was developed using Department of Defense grants of US$14 million from the Telemedicine and Technology Research Center and U.S. Army Medical Research and Materiel Command.
Prices for the LifeBot 5 begin at under $20,000.
