Google's quest to reach the billion or so people in the world who still can't connect to the Internet has produced several novel wireless technologies to make up for slow or poor networks.
One big idea coming later this year will allow Google Maps to work offline, according to a Google executive in remarks made Thursday. Once a map is downloaded over a slower wireless connection, it can be stored and still function in many of the ways it would with a network connection -- a user would still be able to find locations on the stored map, including reviews of stores and their opening hours.
"Google is committed to making our products work well for the next billion" people wanting Internet connections, said Jen Fitzpatrick, vice president of product management for Google Maps during the Google I/O keynote on Thursday. She didn't offer many details on Google Maps running offline, but described the idea at a high level.
Google engineers have recently been able to make turn-by-turn Google Map directions work offline as well, she said. "We're working hard to make Google apps work offline so they won't suck down expensive data or don't have to have super-reliable connectivity every time you want to be somewhere," Fitzpatrick added.
She demonstrated using Google Maps in Mexico City offline in airplane mode on an Android smartphone, finding a restaurant on a city map by name and then producing some of the reviews.
Other techniques Google is trying out include a streamlined version of the Chrome browser that is 10 times smaller than typical Chrome versions. In Indonesia, Google found that it typically took 20 seconds over an older 2G wireless connection to load 1MB of data. But by optimizing connections, users could load a page four times faster.
Also, Google is working with faster and lighter memory requirements for cheaper phones, even those with just 512 MB of RAM. "You can save any page you visit...for later offline access," Fitzgerald said.
While Youtube is extremely popular, even in developing countries, it relies on video that puts a heavy load on bandwidth, Fitzgerald noted. She said users in some countries where Google is at work have been able to view Youtube videos offline with new Google technology -- even where there is no Internet connection.
"Access to good information can change people's lives, but connectivity is often a real challenge or data is too expensive to it make practical to use in large quantities or data transmissions are slow, taking minutes for the loading of a map," Fitzgerald said.
Google is also providing Android One smartphones to users in India, using three manufacturing partners there, Fitzgerald said. She called them "high quality smartphones at a great value."
