Location infrastructure & services are the capabilities and location technologies that allow marketers to trigger location based campains, collect customer location data, message customers in particular locations, and build location-based audiences with relevant (contextual) data.
It's important to recognize what tools will collect the most relevant data. For example, using POI licensing from apps like Yelp and Google vs using a martech vendor like Radar to trigger a notification or take some action based on events sent to Radar and your CDP.
Sometimes there will be confusion about which type of service is required and who can provide that service. When it comes to selecting Location Infrastructure & Service providers, it's important to review the providers through an objective and technical standpoint so you can find the right fit.
