E

Answer to Question 2

A key driver for m-commerce is location-based services, which are highly personalized mobile services based on a user's location. Location-based services are implemented via the cellular network, Wi-Fi networks, and Global Positioning System (GPS) functionality, now built into most modern cell phones. Location-based services allow the service provider to offer information or services tailored to the consumers' needs, depending on their location. For example, search engines can provide specific information about attractions or restaurants located in the user's vicinity, retail stores can enhance store locators with navigation instructions, or users can receive real-time traffic or public transport information.
