Emerging technologies for WLAN
IEEE Communications Magazine, 2015New technologies continue to be introduced for WLAN applications at a robust pace. We review the value proposition for some of the key features of 802.11ac such as larger bandwidth, higher order modulation, and MIMO and MUMIMO transmission modes, explaining how each feature translates to improved user experience.

SPIE Proceedings, 2008
Two different approaches for using a sequence of packets of the IEEE 802.11 (WLAN) protocol as cover for a stenographic communication can be found in literature: in 2003 Krzysztof Szczypiorski introduced a method constructing a hidden channel using deliberately corrupted WLAN packets for communication. In 2006 Kraetzer et al.

IEEE Journal of Solid-State Circuits, 2005
A single-chip IEEE-802.11g-compliant wireless LAN system-on-a-chip (SoC) that implements all RF, analog, digital PHY and MAC functions has been integrated in a 0.18-/spl mu/m CMOS technology. The IC transmits 0-dBm EVM-compliant output power for a 64-QAM OFDM signal. The overall receiver sensitivities are better than -92 and -73 dBm for data rates of 6

User-Centric Offloading to WLAN in WLAN/3G Vehicular Networks
Wireless Personal Communications, 2012In recent years, there has been a growing demand in 3G data services, leading to deteriorating 3G service quality. Noting that Wireless Local Area Networks (WLANs) as well as 3G cellular networks are widely available today, WLANs could be effectively utilized to relieve the overload in the 3G networks.

Just-in-time WLANs: On-demand interference-managed WLAN infrastructures
IEEE INFOCOM 2016 - The 35th Annual IEEE International Conference on Computer Communications, 2016In the past years, the centralized management of dense wireless local area networks has been emerged as a powerful paradigm for improving energy efficiency as well as avoiding severe interference. In this paper, we study the joint optimization on power-operation modes in access points (APs), channel selections and user-AP associations for improving ...

This paper presents a small truncated waveguide fed by a microstrip line through a transverse coupling slot for multi-band WLAN applications. The proposed radiating element allows to obtain a high radiated power, with a very low cross-polar component in the radiated field, with a -10 dB bandwidth that covers the required frequencies for multi-band WLAN

WLAN system trends and the implications for WLAN RFICs
2004 IEE Radio Frequency Integrated Circuits (RFIC) Systems. Digest of Papers, 2004Six trends in WLAN systems are described. For each trend, the implications for WLAN RFICs are described. The six trends include increasing levels of integration, dual band operation, large percentage tuning ranges, very high data rates, long range capability, and PA efficiency enhancements. Potential solutions to these issues are examined.

Proceedings of the 8th workshop on Multimedia and security, 2006
Two different approaches for constructing a steganographic channel in an IEEE 802.11 (WLAN) network are introduced in this paper. First test results on the reliability, undetectability and capacity of a prototypical implementation of both approaches are described and discussed.

Algorithms for WLAN Coverage Planning
2005The impressive market spread of IEEE 802.11 based Wireless Local Area Networks (WLANs) is calling for quantitative approaches in the network planning procedure. It is common belief that such networks have the potentials to replace traditional indoor wired local networks and allow flexible access outdoor, eventually competing with classical cellular ...
