University of Georgia's Center for Continuing Education Replaces Wired Network With Smart Wi-Fi From Ruckus 2008-03-31 Ruckus Wireless

Located on the campus of the University of Georgia (UGA), the Georgia Center for Continuing Education Conference Center and Hotel is considered the world's largest and most comprehensive university-based conference center. UGA's Continuing Education IT staff wanted to provide ubiquitous, free Wi-Fi to hotel guests and visitors for years. But rewiring or adding more wires wasn't an option and finding a Wi-Fi system that could cost-effectively replace the hotel's wired cable network while delivering stable and long-range connections just wasn't available. To cover the entire Georgia Center housing facility, One Media Wireless configured and installed nine Ruckus ZoneFlex 2942 802.11g Wi-Fi access points, 16 Ruckus 2925 Lite Mesh Gateways and one Ruckus ZoneDirector 1025 controller for under $14,000.

Marketing Services Firm Develops Clear Access to Remote LOB Applications 2008-03-12 Microsoft

National Marketing Resources is a 450-employee firm based in Kearney, Missouri, that provides sales and consulting services for entrepreneurs and small businesses in real estate investment and e-commerce. They needed to train new associates in the process of logging in to a new desktop and helping them understand the difference between their own desktop computer and the terminal server also needed to move hosted applications, helpdesk calls elevated. Midwest Technology Connection deployed the upgrade on Intel-based Dell servers, whose multi-core processors will enable future virtualization and server consolidation. Depending on the server role (application, database, or file and print server), TS RemoteApp, Terminal Services Gateway (TS Gateway), Terminal Services Licensing, and Terminal Services Web Access were installed as appropriate.

On Multi-Gateway Association in Wireless Mesh Networks 2008-01-01 Georgia Institute of Technology

Most traditional models of wireless mesh networks involve a mobile device connecting to the backbone through one of the available gateways in a wireless mesh network. This paper presents an alternate model, in which mobile devices are allowed to connect through more than one of the available gateways. It is called as the model Multi-Gateway Association (MGA). The paper present arguments for why such a model can result in better capacity, fairness, diversity and security when compared to the default single-association model. It also identifies the primary challenges that need to be addressed when using multiple-gateway associations, and propose solutions to handle these challenges.

Full System Energy Estimation for Sensor Network Gateways 2008-01-01 Association for Computing Machinery

This paper presents a new energy estimation model for sensor network intermediate gateway nodes (i.e. Crossbow Stargates). Such devices are battery powered and resource constrained and commonly employed as communication, processing, and gateway elements within sensor networks. Understanding and accurately estimating the energy behavior of such devices is the key to conserving the battery life of the system. This approach considers the system as a whole and couples techniques that estimate energy consumption for a wide range of program activity, including computation, communication, and persistent storage access. This model is constructed using empirical data that is collected via hardware performance monitors in the device and novel software performance monitors in the Linux operating system.

Scalable Real-Time Gateway Assignment in Mobile Mesh Networks 2007-12-13 Association for Computing Machinery

The perception of future Wireless Mesh Network (WMN) deployment and usage is rapidly evolving. WMNs are now being envisaged to provide citywide "last-mile" access for numerous mobile devices running media-rich applications with stringent Quality of Service (QoS) requirements. Consequently, some current-day conceptions underlying application support in WMNs need to be revisited. In particular, in a large WMN, the dynamic assignment of users to Internet gateways will become a complex traffic engineering problem that will need to consider load peaks, user mobility, and handoff penalties. The paper proposes QMesh, a framework for user-gateway assignment that runs inside the WMN, and is oblivious to underlying routing protocols. It solves the handoff management problem in a scalable distributed manner.

Completing the 4G Vision: Gateways for Mobile WiMAX 2007-09-01 Farpoint Group

WiMAX is a set of specifications created by the WiMAX Forum and based on standards developed by the IEEE 802.16 Working Group (WG). There are two standards of note here. The first is IEEE 802.16-2004, sometimes called 802.16d, which specifies a common air interface for fixed (both ends stationary) microwave equipment. But since the high-growth market opportunity for wireless of any form today is in mobile systems, the 802.16 WG subsequently issued 802.16e-2005, which specifies a mobile broadband technology.

Optimizing the Internet Gateway Deployment in a Wireless Mesh Network 2007-08-10 Institute of Electrical and Electronics Engineers

In a Wireless Mesh Network (WMN), Mesh Routers (MRs) are interconnected by wireless links and form a wireless backbone to provide ubiquitous high-speed Internet connectivity for mobile clients. The wireless backbone is tightly integrated with the Internet by nodes called as Internet GateWays (IGWs). This paper addresses the IGW deployment problem which is shown to be NP-hard. First it is formulate as a Linear Program (LP) issue, and then develop two heuristic algorithms for the purpose of cost-efficient IGW deployment. The paper further compares these algorithms with a leading approach by extensive simulations. This analysis shows the effectiveness of the proposed algorithms.

UMTS Femtocell as Wireless Residential Gateway 2007-06-01 Aricent

Mobile operators today are trying hard to overcome the challenges posed by intense competition in the wireless communication space. There is an ever-increasing demand from operators to increase ARPU while decreasing cost. New competitors entering the market are posing a big threat to existing players apart from the alternative technologies such as Voice over WiFi. Vendors are under intense pressure to come up with innovative solutions for providing better quality and coverage to mobile subscribers at lower cost. The discussion about UMTS based Femtocell (also called 3G Access Point') that is doing rounds for quite sometime to counter the challenge posed by unlicensed access technologies like WiFi and WiMAX.
