Figure 17: Power and Resource Management values used during the trial. Power Management values, are represented by the cell size and were defined to balance the cell splitting gain and the reduction in interference (SINR). The coloring scheme was defined to minimize the interference between cells, once power management settings were accounted for..

ABSTRACT As mobile data demand continues to increase exponentially due to existing and emerging devices and applications, mobile networks need to prepare for 1000X traffic growth over the next decade. In addition to utilizing more spectrum, the most powerful technique to address this data demand is through network densification, i.e., deploying more small cells to serve a geographical area and thereby achieving cell splitting gains. In this paper, we present how densification of LTE small cells (about 1000 small cells/km 2) in an unplanned manner can effectively increase the network capacity by a factor of over 40 times compared to traditional deployment (normalized with respect to spectrum and service area). This network was deployed in 2013, where initial testing was conducted during one of the NASCAR Sprint Cup race in November 2013. The present document summarized results from the March 2014 race where testing performed in partnership with Sprint, NASCAR, and Airspan, at the Phoenix International Raceway (PIR) to demonstrate the future of wireless networks. NASCAR PIR garage area was chosen for this trial since it created the most challenging test environment imaginable due to: 1) RF challenges (large trucks and dense user environment with mobility), 2) High data capacity demand, 3) Dynamic environment which makes network planning impossible ahead of the race. Basically if hyper-dense small cell …
