Mole: A scalable, user-generated WiFi positioning engine
Jonathan Ledlie,Jun-geun Park,Dorothy Curtis,Andre Mendes Cavalcante,Leonardo Camara,Afonso Costa,Robson D. Vieira +6 more
TL;DR: Mole is described, a mobile organic localization engine that employs several new techniques, including a new statistical positioning algorithm to differentiate between neighboring places, a motion detector to reduce update lag, and a scalable “cloud”-based fingerprint distribution system.

Null subframe indication for coexistence between different network types
Taejoon Kim,Klaus Doppler,Sayantan Choudhury,Zhong-Yi Jin,Robson Domingos,Erik Portel Lope De Almeida,Fabiano Chaves,Andre Mendes Cavalcante,Rafael C. D. Paiva,Fuad Mousse Abinader,Felipe M. Costa +10 more
TL;DR: In this article, the authors proposed a method to detect the presence of a second radio access technology in the same areas of the radio frequency spectrum as a first radio access system by indicating information about a null power subframe.
Patent
Interference avoidance and power savings for coexistence among different radio access technologies
Fuad Junior,Erika Portela Lopes de Almeida,Robson Domingos,Rafael C. D. Paiva,Fabiano Chaves,Andre Mendes Cavalcante,Felipe M. Costa,Sayantan Choudhury +7 more
TL;DR: In this article, the authors propose to detect within a predefined interval, of a resource allocation of the coexisting 2 nd RAT whether the resource allocation (e.g., one subframe) is occupied or vacant.
Proceedings ArticleDOI
Performance Evaluation of IEEE 802.11n WLAN in Dense Deployment Scenarios
Fuad Mousse Abinader,Erika Portela Lopes de Almeida,Sayantan Choudhury,Vicente A. de Sousa,Andre Mendes Cavalcante,Fabiano Chaves,Esa Tuomaala,Robson D. Vieira,Klaus Doppler +8 more
TL;DR: This paper compares DCF with an existing Wi-Fi mechanisms, Power-Save Multi-Poll (PSMP) and Hybrid Coordination Function (HCF) Controlled Channel Access (HCCA), and shows that, although standard scheduled access techniques enhance WiFi throughput, they also suffer a decrease on performance in dense deployments.

Performing measurements in wireless network
Fuad Mousse Abinader,Fabiano Chaves,Erika Portela Lopes de Almeida,Andre Mendes Cavalcante,Robson Domingos,Sayantan Choudhury,Klaus Doppler,Mika Kasslin +7 more
TL;DR: In this paper, the measurement groups in a wireless network are assigned by broadcast messages transmitted in the wireless network and the measurement group may be announced by measurement group information comprised in a broadcast message.
