whitepaper The T-Mobile HotSpot@Home UMA Service on a University or Enterprise WLAN2009-02-07 Aruba Networks
  Off late the features of dual-mode devices (cellular voice and data clients with additional Wi-Fi radios) have grown increasingly sophisticated. The burgeoning capabilities of these devices have attracted the attention of IT staff at enterprises and universities with campus environments because of potential synergies with already installed wireless LANs. More specifically, the potential exists for a user to carry a single device that leverages Wi-Fi coverage where cellular reception is poor, thereby lowering telecom expenses and improving the user browsing experience because of Wi-Fi's higher data rates.

whitepaper A Vertical Media-Independent Handover Decision Algorithm Across Wi-Fi and WiMAX Networks2009-02-05 Institute of Electrical and Electronics Engineers
  The hybrid networks of Wi-Fi and WiMAX networks can provide high data rate and enhanced multimedia services, but it is challenging to obtain optimized handover decision based dynamic QOS information. Users can improve their perceived QOS by using the terminal-controlled handover decision in a single device equipped with multiple radio interfaces. The IEEE 802.21 aims at providing a framework that defines Media Independent Handover (MIH) mechanism that supports seamless handover across heterogeneous networks. This paper proposes a handover decision algorithm using MIH services in Wi-Fi and WiMAX networks with QOS provision. The simulation results show that the proposed algorithm provides smaller handover times and lower dropping rate than the basic vertical handover method.

whitepaper Finding the Best Fit - Wi-Fi Versus WiMAX2009-02-01
  Wi-Fi and WiMAX are two different technologies that often compete in fixed and nomadic deployments. This paper discusses which technology provides the best fit for different applications. The discussion reviews aspects such as the affect of frequency licensing on the technology in terms of interference, bandwidth and power. The cost of the technology is also reviewed on the operator side and the cost of clients. The discussion highlights the strengths and weaknesses of each technology. Wavion spatially adaptive, beamforming Wi-Fi technology is specifically designed for metro deployments. This enables Wavion's WBS-2400 base station to successfully deal with most of the traditional disadvantages Wi-Fi technologies. With Wavion's Wi-Fi solution, operators are able to deploy high quality, cost effective wireless infrastructures.

whitepaper Simulation Vs. Emulation: Evaluating Mobile Ad Hoc Network Routing Protocols2009-01-01 Carleton University
  In order for simulation studies to be useful, it is very important that the simulation results match as closely as possible with the testbed results. This paper compares emulated testbed results with simulation results from NS2 and GloMoSim. OLSR was used as a routing protocol and NRL Mobile Network Emulator (MNE) for dynamic topology control and manipulation. Five Linux based laptops, equipped with IEEE 802.11b wireless network cards were used for testbed implementation. At low traffic rates, testbed results matched closely with the simulation results, at higher traffic rates, testbed results not only differed from the simulation results both qualitatively and quantitatively but the simulation results from both the simulators were barely comparable in some scenarios.

whitepaper Lessons Learned Constructing a Wireless Ad Hoc Network Test Bed2009-01-01 University of Colorado
  This paper describes lessons learned constructing a wireless mobile ad hoc network test bed at the University of Colorado at Boulder. The test bed described in this paper is designed to facilitate experiments based on wireless ad hoc networks including radios mounted at fixed sites, on ground vehicles, and in small Unmanned Aerial Vehicles (UAVs). Laptop computers, PDAs, and special-purpose ad hoc radios running the Dynamic Source Routing (DSR) protocol over IEEE 802.11b serve as nodes in this test bed. The paper discusses various components of the test bed and also makes a note of issues faced during experimentation and lessons learned in this process.

whitepaper Wi-Fi Client Device Security and Compliance With PCI DSS2009-01-01 Summit Data Communications
  Wi-Fi Client Device Security and Compliance With PCI DSS is every retailer's nightmare: An attacker exploits weak network security at a retail store to steal information from customers' payment cards (credit cards and debit cards). The theft affects everyone in the retail supply chain, including the retailer, its customers, banks, and payment card companies. The retailer, however, is the one hammered by bad publicity. In addition to costing the retailer business, the bad publicity sullies the retailer's reputation, forever linking its name to the theft. This white paper focuses on client devices that connect to a network using wireless LAN, or Wi-Fi, technology. A robust, standards-based approach to Wi-Fi client security aids in PCI DSS compliance by protecting the data that clients transmit and receive and the networks to which they connect.

whitepaper Motorola M2M Wireless Modules: W24 Wi-Fi Module Product Features2009-01-01 Motorola
  Motorola's W24 Wi-Fi module is designed to be the ultimate communication solution for multiple M2M devices. With easy Wi-Fi (802.11b/g) access to internet and data connections for cost effective and secure broadband connectivity, the W24 meets the needs of M2M applications like AMR, AVL, ePOS, Home Automation, Security and Telemedicine. The W24 includes built-in connectivity to the G24-GSM and C24-CDMA modules for Wi-Fi to cellular data routing (connectivity to the H24- HSPA module is currently being developed). The W24 stack leverages a single design, and is therefore a perfect solution for M2M applications requiring both communication types, like fleet management, security or AMR devices.
