 ## Localized Corrections
 
 The u-blox PointPerfect Localized correction service via MQTT (IP) offers quick delivery of high precision accuracy by providing your device only the SPARTN corrections applicable to your location. This feature offers several advantages over the traditional continental streams, including significantly reduced bandwidth requirements and seamless transition between regions.

 PointPerfect Localized works by dividing the coverage area into a grid of tiles. Each tile contains a set of nodes that are relevant to a user located within that tile. Unlike the continental level approach where a device subscribes to the continental level topic, in the localized approach a device subscribes to the localized node topic based on its location. This ensures that the device receives only the correction data that is relevant to its location, greatly reducing the required bandwidth.

 PointPerfect keys are valid for a maximum of 56 days. During that time, the RTK device can operate normally without the need to update keys. However, when the keys are set to expire in 28 days or less, the RTK device will attempt to log in to WiFi at each power on. If WiFi is not available, it will continue normal operation.
