Comparison of wireless communication techniques.

Technique	Frequency; (GHz)	Data rate; (Mbps)	Power; (dBm)	Distance	Inf
Zebee [93]	2.4, 0.865	0.25	−3~10	10 m	high
Bluetooth [94]	2.4	0.72124	<20	10 m	high
UWB	310	0.8520	−41	10 m	high
ICL	0.001~0.4 [15]	0.0001–4 [95]	—	0.5~3 cm	low
Cap-HBC	0.01~0.1	0.002~10	−155	5 cm~2 m	low
Gal-HBC	0.0001~0.01	0.0009~2	−30~−4	5 cm~40 cm	low

Inf: interference; ICL: inductive coupling link; Cap-HBC: capacitive coupling HBC; Gal-HBC: galvanic coupling HBC.
