MULTI-GIGABIT COMPRESSION - LIGHTPOINTE AIREFORCE

SECURITY AND ENCRYPTION WITH THE LIGHTPOINTE AIREFORCE This document highlights the Security and Encryption (EtherCRYPT) features of the LightPointe AireForce System. ETHERPACK - ETHERNET LOSSLESS PACKET COMPRESSION This whitepaper explains EtherPACK - Ethernet Lossless Packet Compression. The LightPointe AireForce system has adapted this lossless packet compression technology for networking applications, targeting in-flight data, to better enable next generation network concepts of cloud computing and data center virtualization. The LightPointe AireForce platform optimizes network performance and secures network traffic via its unique ability to compress (EtherPACK), and encrypt (EtherCRYPT) any traffic type on multiple ports. The flexible optimization engine ensures extremely low latency, dropped packet immunity and rich statistics/SLA monitoring.

OPTICAL WIRELESS - FREE SPACE OPTICS

AN INTRODUCTION TO FREE SPACE OPTICS This short white paper is intended to provide valuable background and resource information on FSO technology. Whether you're a student, an engineer, account manager, partner, or customer, this paper provides the FSO insight you may require. And for providing high-speed connections, across Enterprises and between cell-site towers, it is one of the best technologies available. THE PHYSICS OF FREE SPACE OPTIC TECHNOLOGY The goal of this paper is to explain some of the design issues surrounding FSO systems and provide sufficient information to allow potential users to evaluate the suitability of a specific FSO system for a particular application. In addition, this document will attempt to define the realistic performance limitations of FSO based upon existing technology, as well as set reasonable expectations with regard to atmospheric conditions. FREE SPACE OPTICS - SYSTEM DESIGN This paper addresses some of the issues that are most important in the design of an overall carrier system architecture. Briefly described are the basic physics of transmission at various short and long infrared wavelengths and their overall impact on the system design. OPTICAL WIRELESS SECURITY Network security is one of the major concerns for any business or organization transporting sensitive and confidential information over its network. This white paper discusses security aspects involving the physical layer. POWER OVER ETHERNET TECHNOLOGY Power over Ethernet (PoE) technology allows LAN equipment such as IP telephones, wireless LAN Access Points, and now—optical wireless link heads—to be powered over existing LAN cabling without modification to the existing Ethernet infrastructure. PoE technology offers the first truly international standard for power distribution.

MILLIMETER WAVE WIRELESS

MILLIMETER WAVE TECHNOLOGY In 2003 the North American Federal Communications Commission (FCC) opened several high frequency millimeter-wave (MMW) bands, namely in the 70, 80, and 90 gigahertz (GHz) ranges, for commercial and public use. Due to the vast amount of spectrum (roughly 13 GHz) available in these bands, millimeter-wave radios have quickly become the fastest point-to-point (pt-to-pt) radio solution on the market. MILLIMETER WAVE - ROI FOR THE ENTERPRISE Commercial MMW radio systems are priced at such levels that they can be implemented at a fraction of the cost associated with trenching fiber. The payback period compared to leasing higher capacity fiber connection is typically far less than 12 months. This extremely short return-on-investment (ROI) period makes the economics of gigabit connectivity very attractive. MILLIMETER WAVE - LIGHT LICENSING Radio systems in these millimeter-wave bands are characterized by their highly directional “pencil beam” transmissions. These characteristics allow for excellent frequency reuse since systems can be engineered to operate in close proximity to one another without causing interference. For this reason, the FCC adopted an innovative licensing approach specifically for these bands. Rather than mandating a traditional, cumbersome, and time consuming coordination and licensing approach, as widely used for lower frequency microwave links via the standard ULS database, the FCC defined a unique online link registration process through a shared industry database. THE ECONOMICS OF MILLIMETER WAVE Commercial millimeter-wave systems are priced at such levels that payback against trenching fiber is a few months, and against leasing fiber capacity is much less than one year. This pricing makes the economics of gigabit connectivity very attractive. This paper explores the economics of E-Band wireless in more detail, outlining the costs for wireless and alternative systems to provide Gigabit per second connectivity.
