Isolation between V and H Polarizations (XPD)

Sufficient isolation (XPD) observed (no deterioration in the video signal).

Multiplex transmission using dual polarization is an effective way to increase user capacity.

Conclusion

60-GHz video transmission link in the dome has achieved

• 220-m transmission

• Constant characteristics

• Sufficient XPD

This link will play an important role as an entrance link for WPAN in the dome and other places
