Before revision:  In particular , we show that smaller antenna beamwidths and, unlike bi-dimensional mmWave cellular networks, smaller BS densities do not necessarily have a disruptive impact on improving the SINR outage probability , and consequently the rate coverage probability .
After revision:  In considered highway scenarios , we show that smaller antenna beamwidths and, unlike bi-dimensional mmWave cellular networks, smaller BS densities do not necessarily have a disruptive impact on improving the SINR outage probability , and consequently the rate coverage probability .
