White Space Networking With Wi-Fi Like Connectivity | 2009-08-21 | Association for Computing Machinery |
| Networking over UHF white spaces is fundamentally different from conventional Wi-Fi along three axes: spatial variation, temporal variation, and fragmentation of the UHF spectrum. Each of these differences gives rise to new challenges for implementing a wireless network in this band. The paper presents the design and implementation of WhiteFi, the first Wi-Fi like system constructed on top of UHF white spaces. WhiteFi incorporates a new adaptive spectrum assignment algorithm to handle spectrum variation and fragmentation, and proposes a low overhead protocol to handle temporal variation. WhiteFi builds on a simple technique, called SIFT, that reduces the time to detect transmissions in variable channel width systems by analyzing raw signals in the time domain.

How a Spanning Tree Works | 2009-06-23 | Global Knowledge |
| The way a switch learns Ethernet (MAC) addresses is by inspecting the Ethernet frame and recording the source MAC address in a dynamic table. The switch will also associate a learned MAC address with a port. It can then make intelligent forwarding decisions based on the destination MAC address. This white paper illustrates the process. This white paper focuses on Spanning Tree Protocol (STP), IEEE Standard 802.11, and addresses the functions of an Ethernet LAN switch.

Case Study: D-Link Brings Affordable, Single Network Wi-Fi Solution to Redeemer University College for Enhanced Internet Access and Reliability | 2009-06-18 | D-Link |
| Redeemer University College is an undergraduate Christian liberal arts and science university committed to academic excellence. Redeemer University College was being hindered by its spotty, unreliable Wi-Fi network that was patched together with random access points and lacked central communication. Faced with tight budget requirements, the school set out to deploy a universal wireless solution that would blanket the 90-acre campus - including academic buildings, student dorms, the auditorium, gymnasium and several outlying structures - under a single network integration. Vanderkolk and his network associate installed one D-Link DWS-3026 control switch and 48 D-Link DWL-3500AP access points during the summer, calling the process "A piece of cake." The total wireless solution offers many benefits to Redeemer both from a student and administrative standpoint.

Lowering 3G Bills and Increasing Availability With Wi-Fi: Why Hotspots Make Sense for Smartphone Users | 2009-05-04 | iPass |
| Smartphones and other Web-friendly mobile devices are taking enterprise IT departments by storm, and are often brought into the workplace as employees' personal devices. While analyst firms IDC and Strategic Analytics both confirm that sales of cellular handsets dropped sharply during the first quarter of 2009 as part of the global economic recession, the smartphone market is still going strong. In fact, Apple's iPhone unit increased sales by 123 percent in the first quarter of 2009. As smartphones grow in popularity, IT staff must face the realities of supporting them, addressing the increased complexity, security and cost issues that these new devices place on the organization. iPass has a proven track record for simplifying complexity, increasing security and managing costs for supporting mobile laptop users.

Wireless Technologies in Industrial Markets: An Examination of Mesh Technologies in Mining | 2009-03-01 | Motorola |
| Motorola's Wireless Broadband Mesh product portfolio has been designed to offer maximum flexibility, offering both 802.11-based solutions and solutions with Motorola's industrial strength MEA (Mobility Enabled Access) technology for critical applications and harsh environments. When paired with Motorola's advanced MeshConnex routing algorithm, either access technology can provide a robust connectivity solution for a city, an agency or a business. This paper is the first in a series of solutions papers on how 802.11 and MEA technologies can be used in the most demanding RF environments in the world. This paper examines real world applications for mining, and the unique strengths and capabilities of each of the wireless technologies.
