IEEE 802.11ac: Enhancements for very high throughput WLANs
TL;DR: This paper introduces the key mandatory and optional PHY features, as well as the MAC enhancements of 802.11ac over the existing802.11n standard in the evolution towards higher data rates, and demonstrates that hybrid A-MSDU/A-MPDU aggregation yields the best performance for both 802.

System performance of LTE and IEEE 802.11 coexisting on a shared frequency band
Timo Nihtila,Vitaliy Tykhomyrov,Olli Alanen,Mikko A. Uusitalo,Antti Sorri,Martti Moisio,Sassan Iraji,Rapeepat Ratasuk,Nitin Mangalvedhe +8 more
TL;DR: The system performance analysis of 3GPP Long-Term Evolution (LTE) and IEEE 802.11 Wireless Local Area Networks (WLAN) in a situation where LTE downlink has been expanded over to unlicensed frequency band usually used by WLAN is presented.
Proceedings ArticleDOI
Performance Analysis of IEEE 802.11ac DCF with Hidden Nodes
Zheng Chang,Olli Alanen,Toni Huovinen,Timo Nihtila,Eng Hwee Ong,Jarkko Kneckt,Tapani Ristaniemi +6 more
TL;DR: The results indicate that the traditional RTS/CTS handshake mechanism faces shortcomings and needs to be modified in order to support the newly defined 802.11ac amendment.
Journal ArticleDOI
Fairness vs. Performance in Rel-13 LTE Licensed Assisted Access.pdf
Michal Cierny,Timo Nihtila,Toni Huovinen,Markku Kuusela,Fedor Chernogorov,Kari Hooli,Antti Toskala +6 more
TL;DR: Investigations show that in common scenarios LAA is a fair neighbor to WiFi as is, and even in an extreme scenario only small adjustments to the channel access mechanism are needed to achieve the same outcome.
Proceedings ArticleDOI
Capacity improvement by employing femto cells in a macro cell HSDPA network
TL;DR: The results showed that co-channel femto cells offer considerable gains from both user and network perspective with all receivers even if the Femto cell users are not concentrated near the femto base stations.
