...Compared to pre-WIMAX Line-of-Sight (LOS) systems, [6] and WIMAX NLOS systems, [4], [5], which can operate with tight frequency re-use, for nomadic and indoor systems the re-use factor should be more relaxed, similar to that of mobile systems....

...Recently, there has been significant interest in RotatedInterleaved Channel Assignment (RICA), as the most efficient scheme for fixed access, [4]-[6], and in Interleaved Channel assignment (equivalent of MICA, [4]), [7], [8]....
[...]
...According to [4], the most efficient Rotated-Interleaved Channel Assignment is selected for the all-outdoor deployment, while the Monotonous-Interleaved Channel Assignment (also referred as Interleaved Channel Assignment, [7]-[8]) is selected as the best scheme for all-indoor deployment....

...For different types of networks, several schemes have been proposed in the literature, [4]-[8], where it can be seen that a differentiated performance should be expected when the terminal antenna is directional or omnidirectional, as in fixed or mobile access respectively....
[...]
...According to [4], even a re-use factor of FR = 1 can be applied (a channel is re-used in every cell) in fixed systems and achieve sufficient performance, provided that a careful network planning is adopted....

...Compared to the study in [ 3 ] the trade-off for A-TDD operation is significantly improved due to the concept of sector and terminal directional antennas and RICA in F-BWA, avoiding the cost for complex antenna arrays systems at the base station....

...Interference effects will be quite strong at the base and terminal receivers that use limited directionality antennas (typical 60–90◦ beam-width, [1]) to receive enough indirect paths inside the main lobe and be able to reconstruct the signal in the absence of a line-of-sight (LOS) path....
