... gives an indication of the sensitivity of the performance of the different network layouts for the base station antenna height. Also the signal statistics of the different network layouts are analysed ... the performance of the triangular and square layouts was shown to be at equal level with the clover-leaf layout. Moreover, the performances of these layouts are clear...
