Abstract: In this paper, we consider frequency channel assignment (CA) in the scope of non line-of-sight fixed wireless networks. First we introduce a new, highly accurate, method to characterize CA schemes based on the changes of the sector antenna orientation in co-channel cells along cell rows and columns in the network. With the new characterization scheme as a basis, we propose new CA schemes, such as rotated-interleaved CA (RICA) and rotated-rotated CA (RRCA) and compare them with traditional schemes, such as ICA. Results show that RICA outperforms the other CA schemes, for re-use factors FR=1, 2 both without considering polarization assignment (PA) and when considering cell-by-cell alternative PA.
