... two ways of partitioning links in the Crawford Hill Building. (a) LOS links and all NLOS links. (b) LOS links and three categories of NLOS links, based on number of intervening walls. For each ... 4228 NLOS links can be further partitioned into links with one or two intervening walls (type 1); links with three or four intervening walls (type 2); and links with more than four intervening wal...
