Abstract
The invention discloses a method for fast detection scan of NB-IoT signals in networks. The object of the invention to provide a scanning procedure which is reliable and very fast in order to reduce the search time and hence the power consumption will be solved by a method for fast detection scan of NB-IoT signals in a network by applying a higher sampling rate than 240 kHz and observing a received signal at a receive bandwidth around a magnitude wider than the NB-IoT signal bandwidth of 180 kHz, wherein a set of 2M+1 NB-IoT signals each having a different E-UTRA absolute radio frequency channel number (EARFCN) can be observed simultaneously, whereas M is a natural number and 2M+1 indicates the number of concurrently observed channels.
