A smartcard for authentication in WLANs
Proceedings of the 2003 IFIP/ACM Latin America conference on Towards a Latin American agenda for network research, 2003Wireless LANs based on the IEEE 802.11b standard have spread very quickly over the past few years. Nevertheless a lot of security issues remain and stop its deployment in corporations. One of the most important issues is the authentication of a terminal to an Access Point. We propose an interface to integrate the Extensible Authentication Protocol into

Opportunistic Retransmission in WLANs
IEEE Transactions on Mobile Computing, 2012This paper presents an efficient opportunistic retransmission protocol (PRO, Protocol for Retransmitting Opportunistically) to improve the performance of IEEE 802.11 WLANs. PRO is a link-layer protocol that allows overhearing nodes to function as relays that retransmit on behalf of a source after they learn about a failed transmission.

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.

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 ...

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.

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
