Today, enterprise app developers can tap into a host of location-based apps, mobile location-based services and hyper-local-marketing tools to deliver highly relevant features and content based on where employees or potential customers are. But how do they know which type of location is best for their specific needs?
Depending on your industry and use case, requirements for latency, accuracy, authentication and privacy can dictate the suitability of various location sources.
" Network-based technologies -- where equipment installed in a wireless carrier's network calculates and accesses the location of the phone.
" Handset-based technologies -- where the location information is generated and accessed by a GPS chip installed in the phone.
Many smartphones have a GPS receiver to help them determine location. Handset-based location has the advantage of being easy to deploy. For users, it has the distinct disadvantage of strenuous processing and battery power drain. For developers trying to reach broad audiences, GPS is limited to smart (app-capable) devices with onboard GPS capabilities. This means that handset-based location is available for approximately 100 million devices in the United States. Second, to access handset-based location, the device must have an app installed or preloaded that will obtain a GPS fix using the device's onboard hardware. This limits the reach of applications using this location method.
Because app-based location relies on GPS, it requires a reasonably unobstructed view of the sky to work. Even in ideal conditions, handset-based location can take several minutes to achieve a location fix.
