===== Overview=====
<poem>
[[nblocks:n-ble|n-PRO-WuRx]] is based on AS3933. It is capable of generating a wake-up signal upon detection of a data signal, ranging between 15-150 KHz carrier frequency. The programmable features of AS3933 allows the user to retain consistent wake-up generation for longer distances. It can operate using one, two, or three active channels. Each channel supports a programmable data rate and Manchester decoding.

Some of the targeted applications are listed below:
  * Active RFID tags
  * Real-time location systems
  * Operator identification
  * Passive keyless entry (PKE)
  * Wireless sensors.
