Apple has acquired a Wi-Fi start-up company as they look to bolster mapping and location abilities, following its split with Google.
Monday, Apple confirmed it bought "Wi-Fi Slam," a start-up that has been developing a way to use Wi-Fi hot spots to help smart phones navigate large indoor spaces like airports and conference centers.
Traditional methods of locating cell phones include GPS and sensing of nearby cell towers. Neither approach works well indoors.
The Wall Street Journal reports that Apple paid $20 million for the company.
