Humanitarian Aid agencies want to understand when their beneficiaries arrive at camps or where the majority of them travel. With this information, they make their capacity planning and thus the provision of aid more effective. However, they now arrive at this understanding by manual enumeration, which binds aid workers for hours and is slow. Seita, together with PNGK and IOM, the UN migration agency, is developing the Aileen box, which helps to automate this task by analysing Wifi signals. Aileen includes a cloud dashboard which can make it a very valuable data service for humanitarian aid NGOs of various kinds.
