Organizational Technology Adoption Framework: Wireless LAN 802.11x

Wireless LAN (WLAN) is a recent technology that has not been extensively studied in IS research discipline. The only available literature is mostly vendor reports that glorify the success story of WLAN implementation. The current study attempts to fill this gap by undertaking a qualitative case study approach to investigate important WLAN adoption factors. Based on technology adoption constructs from previous studies, we propose a research model in an attempt to tailor technology adoption theories to the context of WLAN deployment. In order to assess the research model, we interviewed four WLAN equipped organizations. They belong to the four industry sectors that have a high WLAN rate (Cisco, 2003). The results show both similarity and disparity to findings from previous IT/IS adoption literature. In particular, there is a salient adoption difference between non-profit organizations and commercial organizations. In the last two sections, we discuss the implications of the current study to both IS researchers and practitioners and make suggestions for promising avenues of future WLAN research

Wireless LAN 802.11x in U.S. Educational Institutions: Technology Adoption and Digital Divide Perspective

The current study of wireless local area networks (WLAN) adoption in educational institutions is motivated by three reasons. First, most students are exposed to information technology when they are at K-12 schools. Indeed, educational institutions represent the largest segment in the WLAN market in the United States in terms of the number of adopters. Second, WLAN requires a substantial financial investment before it can enable an anytime, anywhere learning environment, and may thereby aggravate the digital divide between rich and poor schools. Third, although WLAN is infrastructure technology, it has different characteristics compared to other infrastructure information technologies; traditional infrastructure information technologies are mostly located such that they are transparent to the users, whereas WLAN is close to end users, so that they directly experience benefits related to mobility and convenience, which eventually impacts organization boundary and business processes. Recognizing the importance of WLAN and its difference from traditional infrastructure information technologies, this dissertation examines how WLAN adoption (i.e., whether or not to adopt WLAN) and deployment (i.e., the extent to which WLAN is used) are influenced by technological, environmental, organizational factors, socio-economic, and policy-related factors. It is based on an online survey of principals of 435 K-12 elementary, middle, and high schools in Missouri, including 190 adopters of WLAN and 245 schools that have not adopted WLAN. The results indicate that perceived benefit is not a significant predictor of WLAN adoption. Unlike previous research, satisfaction with current wired system positively affects WLAN adoption. Some of socio-economic variables also affect adoption of WLAN. Schools near urbanized areas are more likely to adopt WLAN than the schools near rural areas. Furthermore, the government and state subsidy E-rate positively affect WLAN adoption. When examining the determinants of WLAN deployment, perceived benefits of using WLAN significantly affect WLAN usage. Moreover, perceived benefits and barriers strongly affect satisfaction with WLAN, which in turn affects WLAN usage. Satisfaction from using WLAN significantly mediates the effect of various antecedent factors on WLAN usage. Implications of the results for IS researchers, practitioners, marketers, and policy makers are discussed and future avenues of the study are examined

Millimeter-wave Wireless LAN and its Extension toward 5G Heterogeneous Networks

Millimeter-wave (mmw) frequency bands, especially 60 GHz unlicensed band, are considered as a promising solution for gigabit short range wireless communication systems. IEEE standard 802.11ad, also known as WiGig, is standardized for the usage of the 60 GHz unlicensed band for wireless local area networks (WLANs). By using this mmw WLAN, multi-Gbps rate can be achieved to support bandwidth-intensive multimedia applications. Exhaustive search along with beamforming (BF) is usually used to overcome 60 GHz channel propagation loss and accomplish data transmissions in such mmw WLANs. Because of its short range transmission with a high susceptibility to path blocking, multiple number of mmw access points (APs) should be used to fully cover a typical target environment for future high capacity multi-Gbps WLANs. Therefore, coordination among mmw APs is highly needed to overcome packet collisions resulting from un-coordinated exhaustive search BF and to increase the total capacity of mmw WLANs. In this paper, we firstly give the current status of mmw WLANs with our developed WiGig AP prototype. Then, we highlight the great need for coordinated transmissions among mmw APs as a key enabler for future high capacity mmw WLANs. Two different types of coordinated mmw WLAN architecture are introduced. One is the distributed antenna type architecture to realize centralized coordination, while the other is an autonomous coordination with the assistance of legacy Wi-Fi signaling. Moreover, two heterogeneous network (HetNet) architectures are also introduced to efficiently extend the coordinated mmw WLANs to be used for future 5th Generation (5G) cellular networks.Comment: 18 pages, 24 figures, accepted, invited paper

A Review of Hybrid Indoor Positioning Systems Employing WLAN Fingerprinting and Image Processing

Location-based services (LBS) are a significant permissive technology. One of the main components in indoor LBS is the indoor positioning system (IPS). IPS utilizes many existing technologies such as radio frequency, images, acoustic signals, as well as magnetic sensors, thermal sensors, optical sensors, and other sensors that are usually installed in a mobile device. The radio frequency technologies used in IPS are WLAN, Bluetooth, Zig Bee, RFID, frequency modulation, and ultra-wideband. This paper explores studies that have combined WLAN fingerprinting and image processing to build an IPS. The studies on combined WLAN fingerprinting and image processing techniques are divided based on the methods used. The first part explains the studies that have used WLAN fingerprinting to support image positioning. The second part examines works that have used image processing to support WLAN fingerprinting positioning. Then, image processing and WLAN fingerprinting are used in combination to build IPS in the third part. A new concept is proposed at the end for the future development of indoor positioning models based on WLAN fingerprinting and supported by image processing to solve the effect of people presence around users and the user orientation problem
