Note: G. Fettweis has focus on radio technology, not on applications and "costs" for usage. In the application area, NFC is a replacement of contactless cards for payment, using the same security mechanisms. With respect to "sensor networks" and low energy consumption, the limitations to UWB+ will not fulfil those needs.
