Neighborhood Small Cells

Neighborhood small cells (NSCs) are deployed densely in residential areas or in small businesses such as coffee shops. Qualcomm Research’s studies show that this new neighborhood small cells network provides huge capacity gains, the extent of which depends on the small cells’ penetration and other factors including the morphology of deployment. With additional spectrum and sufficient density of small cells, it is possible to reach and exceed 1000x of today’s network throughput.1

Due to the ease of deployment and the fact that customer backhaul and site premises can be leveraged, NSC networks offer tremendous economic benefits in reduced CapEx and OpEx. Just as important, this network model uses standardized small cell architecture adopted by the industry, therefore ensuring full compatibility with legacy networks and mobiles.

NSCs can be deployed on the same carrier as existing macrocells or on a dedicated carrier. The latter is recommended to maximize capacity gains.

As the density of NSCs can be very high, it is essential to have UltraSON features to ensure robust operations of the small cells.

 

 

 

 


1 The baseline scenario is a macro-only deployment with 500 m ISD and 10 MHz bandwidth in 2 GHz carrier frequency. For the NSC scenario, small cells with 100 MHz bandwidth are considered. With 144 small cells and 200 active devices in each macro sector, the DL median user throughput can reach 1000x of the baseline value.
