whitepaper Understanding Spectrum Intelligence2008-06-01 Cisco Systems
  While many bands of the Radio Frequency (RF) spectrum have a dedicated purpose, Wi-Fi operates in an unlicensed band of RF spectrum carved out by the Federal Communications Commission (FCC), with few rules other than limiting the amount of transmit power, and encouraging the use of spread-spectrum technology. On the positive side, the freedom of the unlicensed band has enabled a tremendous level of wireless innovation. These innovations include devices using standardized protocols such as Wi-Fi, Bluetooth, and Zigbee, as well as devices using proprietary protocols such as cordless phones, wireless cameras, wireless bridges, game devices, and so on. As evidenced by the unprecedented variety and number of wireless devices and applications being sold, one thing is clear: people want mobility.

whitepaper The Case for an Untethered Enterprise2008-06-01 Motorola
  While once considered a luxury, Wi-Fi connectivity is now an integral part of the modern enterprise. To that end, most corporate IT administrators are expected to deploy wireless LANs. Until recently, most enterprises have chosen to deploy Wi-Fi in addition to a wired network. But with the introduction of 802.11n, which will typically require a costly upgrade to the wired network as well, enterprises can save significant capital and feel confident in the decision to go completely wireless. Wireless technologies now match or exceed the performance of wired networks - at a significantly lower cost and a significantly higher ease of installation.

whitepaper Discover the Next Stage in Mobility Network Architecture2008-05-28 Cisco Systems
  The attendee of this webcast will learn about an innovative new network architecture from Cisco that will change the landscape of mobility forever. Delivering wireless access any time, anywhere is no longer enough. Mobile employees need secure access to the right applications at the right time to do their jobs effectively. IT managers also need to extend visibility beyond the corporate wireless LAN to disparate cellular and Wi-Fi networks, while simplifying management and security for a growing number of mobile devices with different operating systems.

whitepaper Cyberoam: An Ideal Solution in Educational Environment2008-05-20 Elitecore Technologies
  Al Wahada Private School (AWPS) situated in Sharjah, UAE is committed to quality educational principles aimed at building up students' academic interests, moral values, creativity, behavior and health. The IT Manager at AWPS, Ms. Samah Assaf outlined the basic requirements saying, they have a Wi-Fi network in which their students can access internet from anywhere in the school campus. AWPS wanted all round Internet security in one box to reduce the Total Ownership Cost and maximize returns. AWPS approached Muazzam Qazi, the Product Manager at Haris Al Afaq, a Cyberoam distributor in UAE. From his previous experience in the Education Vertical, Muazzam unhesitatingly suggested Cyberoam. AWPS overcame its initial skepticism of Unified Threat Management solutions and decided to test Cyberoam UTM CR 250i. They deployed Cyberoam in the same scenario gateway mode.

whitepaper Ten Factors to Consider Before Deploying WLAN 802.11n2008-05-06 Nortel Networks
  The introduction of WLAN 802.11n represents an exciting event for customers due to its greatly enhanced capabilities over the existing 802.11 a/b/g standards in terms of capacity, range and reliability. However, before installing any new technology, particularly one based on a draft standard, it is crucial to first consider all of the implications and create an approach that meets the needs and business goals of the organization. Deploying 802.11n involves much more than just an exchange of hardware and software. A wide range of issues need to be carefully considered. This white paper provides a 'Top ten' list of factors that will help one develop a successful strategy for how and when to migrate to this breakthrough next-generation technology.

whitepaper Modeling of Two-Flow Interactions Under SINR Model in Multi-Hop Wireless Networks2008-04-29 State University of New York
  Carrier Sense Multiple Access (CSMA) protocols in Multi-hop Wireless Networks (MHWN) are known to suffer from different forms of the hidden and exposed terminal problems, leading to inefficiency and unfairness. Recent studies have formally characterized the fundamental interactions in the IEEE 802.11 protocol by classifying and quantifying the possible interactions that arise between two interfering single hop links. However, existing studies use a simple disc based propagation models, which do not model the effect of interference accurately in the presence of capture. The paper advances this line of study by developing the analysis and performance models for the two-flow interference problem using a Signal-to-Interference-Noise (SINR) based propagation model with large scale fading.

whitepaper Keells Super Uses Motorola for Real-Time Inventory of Goods2008-04-09 Motorola
  Keells Super is one of the largest super market chains in Sri Lanka. It is a subsidiary of John Keells Holdings PLC, a Sri Lankan blue chip conglomerate. In a single Keells Super store, there are between 12,000 - 15,000 individual items for sale. The IT team wanted to improve both the efficiency and accuracy of the stock taking process. Keells Super wanted to take advantage of mobile computing combined with Wi-Fi technology. Keells Super developed a real-time solution with Crosspoint based on Motorola MC3000 mobile computers, and the new mobile stock verification system was deployed across the Keells Super chain. It is a wireless stock take and verification system linked to SAP (ERP) which is the backend.

whitepaper WPA2 Security: Choosing the Right WLAN Authentication Method for Homes and Enterprises2008-04-09 Global Knowledge
  Ask a hundred CIOs what three things about WLANs (wireless LANs) strike fear into their hearts, and the answers are likely to be similar: Security, Security, Security. Sure, you want good coverage. Sure, you want to minimize drops. But the only way an executive is likely to lose their job over a wireless network is if they end up like the folks at The TJX Companies, who saw millions of credit card numbers stolen from an attack that started with a breach of the WLAN.

This paper will explore the authentication methods available with WPA2 (Wi-Fi Protected Access 2) and identify several important best practices to consider when deploying a wireless network at home or in the enterprise.

whitepaper ZigZag Decoding: Combating Hidden Terminals in Wireless Networks2008-04-08 Massachusetts Institute of Technology
  This paper presents ZigZag, an 802.11 receiver that combats hidden terminals. ZigZag exploits 802.11 retransmissions which, in the case of hidden terminals, cause successive collisions. Due to asynchrony, these collisions have different interference-free stretches at their start, which ZigZag uses to bootstrap its decoding. ZigZag makes no changes to the 802.11 MAC and introduces no overhead when there are no collisions. But, when senders collide, ZigZag attains the same throughput as if the colliding packets were a priori scheduled in separate time slots. The paper builds a prototype of ZigZag in GNU Radio. In a testbed of 14 USRP nodes, ZigZag reduces the average packet loss rate at hidden terminals from 82.3% to about 0.7%.
