Google 's Mission to Protect Hotspot Users

Google will now be masking "hotspot" locations of owners of Wi-Fi. The locations according to Google are used to provide nearby attractions, shops or mapping routes. In order to help protect users, and to respect their privacy, Google has included an "opt-out" service which will allow an access point owner to opt out from having Google locate their device. The service is set to be released globally later in the fall. Consumers will be glad to know that their locations will be tracked by services such as Google, and that their browsing habits will not be transferred to other advertising outlets. Although this service would be available to Wi-Fi owners, would it also be available to general users? Would it just be effective while using a smartphone or also on other devices such as laptops, etc?
