SMALL CELL SOLUTION

Multiband Capacity utilization Compact design Small cell picks up for 5G

Mobile users expect app availability everywhere, at any time, on all smart devices. This demand drives mobile network operators to start planning for dense heterogeneous networks (HetNets). It is predicted that new deployments of small cells will increase by 50% in the 2018-2020 period, with a second sharp rise in 2023-2024 for 5G densification.

Market shows that residential small cell dominate new deployments, but non-residential small cell 40% deployments are growing at CAGR of 36%, operators expect to deploy between 100 to 350 and deployments will be 22 times higher by small cells per km² in the areas they plan to 2025. densify by 2020.

Deploy the right Operators see small cells as the key to offer improved depth of coverage and boost traffic and voice services in solution to maximize densely-populated urban areas. To maximize return on ROI and enhance user investment, small cell site locations must be determined based experience on actual, localized data traffic demand.

Considering the right small cell for network deployment with the following important points

power level of small cell regional band allocation coverage area the number of users serviced

The above findings are extracted from Small Cell Forum surveys of 1. Deployment plans and business drivers for a dense HetNet: SCF operator (SCF194.10.01), December 2017 2. Small cells market status report December 2017 (SCF050.10.01) Small cell solution for home, enterprise and public facilities
