Wireless Interface

 IEEE Standard: IEEE 802.15.4g
 Operating Frequency:
– NA923: 923MHz (920.8~924.4), BW:400KHz
– EU868: 868MHz (865.2~868.8), BW:400KHz
 Data Rate: 625bps / 2.5k bps / 5k bps / 50k bps
 Antenna Gain
– 902~928MHz: 1.48 dBi
– 863~870MHz: 2.02 dBi
 Transmit Power: This module is up to +12dBm, but real applications need to fol-
low local regulations (e.g. FCC, 0 dBm at 625 /2.5K /5K bps; 10 dBm at 50Kbps)
 Tx
– 115 dBm at 625bps(Long-Rang Mode)
– 100 dBm at 50Kbps
 Topology: Star
 Network Capacity: Up to 64 end nodes (WISE-221X)
