mmWave site design: ISD, street-level vs rooftop, pole-mount

Inter-Site Distance for mmWave

mmWave deployments require significantly denser site spacing than sub-6 GHz networks. Typical inter-site distances range from one hundred to two hundred meters in urban environments compared to five hundred meters to two kilometers for mid-band. This dense spacing ensures overlapping coverage that maintains connectivity as subscribers move between cells or when line-of-sight is temporarily blocked. Site density directly impacts deployment cost, requiring careful balance between coverage reliability and economic feasibility. Dense urban canyons with tall buildings may need even closer spacing…
