Significant regional differences on the use of frequency bands deriving from rain
intensity statistics

13. WI#4: V-band interference analysis
• Analysis of interference in dense
deployment of V-Band PP radio at street
level
• Two scenarios are considered:
• BH carried on by means of
traditional FS systems, ETSI compliant
• BH carried on by means of WiGig
systems
• Main target is to evaluate performance
and robustness to interference using ETSI
parameters also in case of WiGig-like
deployment for Backhauling, where
channel bandwidth is much wider (10
times) and no ATPC available

Available Channels
Interference figures with WiGig-like channels
64-QAM - 32 dBi
64-QAM - 38 dBi
Due to the wide WiGig BW and consequent low number of available
channels, an adequate interference figure is very problematic
Narrower channels reduce interference levels
Next step: evaluate interference level when WiGig & FS share the same band
