Short-range wireless communication device (SRD): Short Range Device, a short-range wireless communication device usually refers to a device with an operating frequency between 25MHz and 1000MHz and a transmission power within 500MW (27dbm). SRD devices often work in free frequency bands. Due to the shortage of existing frequency band resources, congestion and mutual interference often occur. Many ISM (Industrial, Scientific and Medical) frequency bands used in different services also coincide with short-range wireless communication devices (SRD).
