Wireless quantum communication is characteristic of huge information quantity

transmission instantaneity and good security.On the basis of studying the quantum propagation characteristics in free space

this paper summarizes the entangledstate distribution mechanism of wireless quantum transceivers

and presents a wireless quantum hierarchical network structure suitable for wireless Wide Area Networks（WAN）.Furthermore

for performing channel coding

making its performance close to the system tolerance and converting quantum channel coding into classical coding

it proposes adopting the 3-qubit channel coding

and gives an irregular coding/decoding scheme and analyzes its performances using the EXIT chart.The results indicate that this system architecture is suitable for the future applications of wireless quantum communications.
