Over the past decade, the demand for indoor positioning and Location-Based Service (LBS) has become increasingly urgent. Although various indoor positioning technologies are flourishing, there is currently no single technology comparable with GNSS which can perfectly solve the problem of outdoor positioning. While the traditional positioning technology are constantly improving and continues to mature, new ideas for indoor localization are emerging with the development of 5G, Internet of Things, big data and artificial intelligence (AI), etc.

Since the first edition of the international conference on Indoor Positioning and Indoor Navigation (IPIN) was launched in 2010 in Zurich, Switzerland, IPIN has become a global platform dedicated to indoor localization technical discussion and competition. Each year, IPIN attracts hundreds of researchers, students and enterprises from countries and regions all over the world. In 2022, the 12th IPIN Conference and the 9th IPIN Competition will come to China for the first time to be held in Beijing, an ancient capital with a history of thousands of years.
