Apple Wants to Map Your Favorite Malls and Airports

In a move that could intensify the battle between Android and iOS,

has reportedly acquired an indoor GPS company to begin mapping malls, airports and other hotspots.

According to

, Apple may have paid as much as $20 million for WiFiSLAM, a two-year-old startup. While the deal has not been announced publicly, there are already signs that the company is under new management. The company's Twitter page,

, has not been updated with a new tweet since January 23. That account links to

by Apple. Founded by Joseph Huang (a former software engineer intern at Google), Jessica Tsoong, Darin Tay and Dave Millman, WiFiSLAM developed technology to pinpoint a smartphone's location within 2.5 meters. The company uses ambient Wi-Fi signals (which are already present in many buildings) to provide this info in real-time. By acquiring WiFiSLAM, Apple will be able to bring indoor maps of malls, airports, convention halls and other indoor complexes to iOS. Apple is not the first company to explore the possibilities of indoor maps, however. Two years ago,

announced that it would bring indoor maps exclusively to its mobile phone platform, Android. IKEA, Mall of America and

, developed most of its mapping technology in-house. While Apple has more individuals on its payroll (

as of October 2012), the company has enlisted in the help of outsiders to build and tweak its various mapping tools. Apple stunned the world when it announced that Google Maps would not be included as the default maps app with iOS 6. The iPhone maker replaced Google Maps with its own application (which was simply titled "Maps"), promising users that it would

a "better way" for users to find their destination. That goal proved to be a greater challenge than Apple anticipated, leading to a legion of complaints and an
