Handover Mechanism in 5G mmwave Band

5G networks are the next generation of mobile internet connectivity. Mobile data traffic may reach 30 Exabyte's per month. Microwave bands may reach saturation state to deliver the increment of data rate. Millimeter(mmwave) band is a promising band between 30 to 300 GHz. The main advantages of mmwave band are its small antenna radius and high attenuation. Handover in 5G mmwave is challenging because of its short cell radius where user equipment may perform a greater number of handovers meanwhile increasing handover delay. This paper presents the work of modification of ×2 handover mechanism in 5G mmwave network. It mainly deals with reducing handover delay in 5G mmwave network considering different trajectories such as Horizontal trajectory and combination of horizontal and vertical.
