Abstract
Addition of devices of different form factors to the network has resulted to high demand for broadband access. To improve the network capacity, Frequency spectrum regulators have recommended fifth generation (5G) network for deployment on one of the high frequency bands due to their huge contiguous bandwidth. Since such bands have already been allocated to satellite networks by the regulatory bodies, 5G must coexistence with the satellite systems. As a result, feasibility study for coexistence of 5G with the incumbent satellite systems is needed. This paper studied coexistence feasibility of a 5G terrestrial Base Station (BS) with Fixed Satellite Service (FSS) terminal at 28 GHz considering only interference from the satellite terminal into the 5G terrestrial BS. The study used signal to interference plus noise ratio (SINR) available at sectors of a 3-sector cell 5G terrestrial BS as a protection parameter. The available SINR on each sector was used in estimating the impact of the FSS terminal transmit power on the deployment parameters of the 5G system. Moreover, the study was conducted using a more realistic path loss model and 5G antenna pattern recently rd released by 3 generation partnership project (3 GPP). The results show that the transmission power and elevation angle of the FSS terminal affect deployment parameters of the 5G terrestrial BS. Finally, the results suggested that coexistence of the two systems is feasible in residential areas with only one FSS terminal if the deployment parameters of the 5G BS are carefully selected.
