Bluetooth Simple Pairing and Wi-Fi Protected Setup specify mechanisms for exchanging authentication credentials in wireless networks. Both Simple Pairing and Protected Setup support multiple setup mechanisms, which increases security risks and hurts the user experience. To improve the security and usability of these specifications, we suggest defining a common baseline for hardware features and...

Super Wi-Fi is a Wi-Fi-like network built upon TV white spaces (TVWS) exploiting cognitive radio (CR) techniques. Super Wi-Fi is expected to achieve larger coverage than today’s Wi-Fi thanks to its superior propagation characteristics, while suffering from smaller bandwidth compared to Wi-Fi (6–8 MHz versus 20 MHz) which limits its network capacity. Therefore, it has been a common belief that S...

The radio-over-fiber (RoF) technology is a suitable solution to provide high bitrates and to improve the IEEE 802.11 WLAN coverage. Those systems use an optical network to distribute the radio signal from the access point to several remote antennas. Our research project consist in the investigation of the Medium Control Access (MAC) layer performance of those networks. We decided to achieve our...

The new international standard IEEE802.11p (WAVE) defined enhancements to IEEE802.11 (Wi-Fi). A new mobile e-business platform of Wi-Fi and WAVE is described. Based on cognitive radio, the popular wireless network Wi-Fi can collaborate with WAVE in their common unlicensed spectrum band and licensed spectrum band. As a core technology in the cognitive radio field, OFDM is introduced, and a novel...

Internet of Things (IOT) offers a new dimension technology and information where connectivity is available anywhere, anytime, for any purpose. IEEE 802.11 Wireless Local Area Network group standard that developed to answer the needs wireless communication (WI-Fi). Recently, working released 802.11ah or Wi-Fi HaLow as Wi-fi standard. This works on 1 GHz frequency band with broader coverage area,...

Full-duplex Wireless: Design, Implementation and Characterization. by Melissa Duarte One of the fundamental assumptions made in the design of wireless networks is that the wireless devices have to be half-duplex, i.e., they cannot simultaneously transmit and receive in the same frequency band. The key deterrent in implementing a full-duplex wireless device, which can simultaneously transmit and...

Both free and low-priced mobile wireless networks are expanding and its users are more numerous every day. This success is particularly due to the mobility offered to users. These networks have promoted and widespread the success and availability of mobile devices and their access technologies such as Wi-Fi, WiMAX and Bluetooth. Nevertheless, despite of their wide success, the problem is that t...

This paper presents a description of the existing wireless technology Wi-Fi and WiMAX, and try to compare Wi-Fi (IEEE 802.11) and WiMAX (IEEE 802.16), with respect to which technology provides a better solution to build a wireless access infrastructure. Each technology is evaluated based on some key characteristics. This paper concludes with a statement of, which technology will be the best and...
