Summary In this paper, we address mainly 2 important issues, namely, characterizing co‐channel interference and enforcing a minimum distance between femtocell base stations (FCBSs) for reusing resources in FCBSs deployed 3‐dimentional multi‐floor building. Each floor is modeled as group of square‐grid apartments, with one FCBS per apartment. We propose simple yet reasonable analytical model by using planar‐Wyner intra‐floor linear‐Wyner inter‐floor modeling 3‐dimensional building to derive...

After its launch in 2012, OF@TEIN project has faced several changes both resource configuration and usage procedure for infrastructure. In order to maintain and verify the functionality of this open/shared virtual playground, there were many difficulties managing multi-national distributed infrastructure as a collaborative community effort. paper, we discuss past on-going experience on collaborative operation enhancements. Based experience on OF@TEIN virtual playground, could build our...

Abstract In this paper, a multi-band enabled femtocell base station (FCBS) and user equipment (UE) architecture is proposed in multi-tier network that consists of small cells, including femtocells picocells deployed over the coverage macrocell for splitting uplink downlink (UL/DL) as well control-plane user-plane (C-/U-plane) 5G mobile networks. Since performed at same FCBS, we define based split (SBSA). For multiple bands, consider co-channel (CC) microwave different frequency (DF) 60 GHz...

Bangkok is notorious for its chronic traffic congestion due to the rapid urbanization and haphazard city plan. The Sathorn Road network area stands be one of most critical areas where gridlocks are a normal occurrence during rush hours. This stems from high volume demand imposed by dense geographical placement 3 big educational institutions insufficient link capacity with strict routes. Current solutions place heavy reliance on human control expertises prevent disentangle consecutively...
