This paper addresses the comparison of characteristics between the prospective allocated bands for MBS by the International Telecommunications Union, 40 and 60 GHz, and its consequences in the optimization criteria for the cellular design. The key difference between the two bands is the oxygen absorption attenuation which is negligible at 40 GHz, but presents high values at 60 GHz, larger than 10 dB for the typical reuse distance. At 60 GHz the carrier-to-interference ratio is larger, and depends on the coverage distance, while at 40 GHz this dependence does not exist. At 60 GHz lower values for the co-channel reuse factor are obtained and, as a consequence, a larger system capacity is achieved.
