Socioeconomic Inequality and Student Outcomes in Finnish Schools

Abstract

The different types of drones can be differentiated in terms of the type (fixed-wing, multirotor, etc.), the degree of autonomy, the size and weight, and the power source. These specifications are important, for example for the drone’s cruising range, the maximum flight duration, and the loading capacity. Aside from the drone itself (i.e., the ‘platform’) various types of payloads can be dis- tinguished, including freight (e.g., mail parcels, medicines, fire extinguishing material, flyers, etc.) and different types of sensors (e.g., cameras, sniffers, mete- orological sensors, etc.). Applications of different payloads will be described. In order to perform a flight, drones have a need for (a certain amount of) wireless communications with a pilot on the ground. In addition, in most cases there is a need for communication with a payload, like a camera or a sensor. To allow this communication to take place frequency spectrum is required. The requirements for frequency spectrum depend on the type of drone, the flight characteristics, and the payload. Since frequency spectrum does not end at national borders, interna- tional coordination on the use of frequency spectrum is required. Legal
