<p>Video is an important factor of the load in cellular<br>
networks due to the growing popularity of streaming and<br>
linear services. In unicast transmission mode, the same data is<br>
transmitted as many times as the number of receivers demanding<br>
the same video content. Conversely, in broadcast transmissions<br>
using the Single Frequency Network (SFN) technique, a set of<br>
base stations perform synchronized transmission of the same<br>
waveform to a potentially infinite number of users. The objective<br>
of this study is to compare the performance of unicast and<br>
broadcast. More precisely, we determine the minimum number<br>
of users downloading the same data from which a broadcast<br>
transmission is more efficient than multiple unicast transmissions.<br>
In this paper, a model to calculate the Signal-to-Interference-plusNoise Ratio (SINR) in unicast and broadcast modes is presented,<br>
considering Poisson distributed base stations, path loss, fading,<br>
shadowing, trisectored antennas, SFN with a different number<br>
of base stations and beamforming in unicast mode. Results show<br>
that even when an SFN is formed by just 2 base stations and<br>
unicast transmissions are performed using beamforming with 8<br>
antennas per sector, broadcast outperforms unicast when there<br>
are at least 8 users per cell demanding the same content.</p>
