Cut-Rate Batteries has entered on-line two-way radio battery market with launch of its new site, www.cutratebatteries.com. Our website provides consumers with a better alternative to original battery manufacturers of two-way radio equipment such as Motorola and Kenwood on both price and quality. Business consumers have shown enthusiasm for new site as an easy way to stock up on battery inventories.

Cut-Rate Batteries, an international distributor of batteries for two-way radio and barcode scanning equipment announced launch of its online store, last week, at . Targeting business consumer markets for two-way radio and barcode scanner batteries, Cut-Rate Batteries is hitting some of biggest players in industry where they are least able to compete: Price.

Network security is one of major concerns for any business or organization transporting sensitive and confidential information over network. Such network security concerns involve lowest network layer, typically referred to as physical layer (layer one), as well as higher software layers of networking protocols. Most of interception activity by outside intruders occurs within higher protocol software layers. Password protection or data encryption are examples of counter measures to protect network from outside and unwanted tampering. Intrusion of physical layer itself can be another concern for network operators, although it is a far less likely target for unauthorized access to networking data. This can be a threat if information is transported over a copperbased infrastructure that can be easily intercepted, but optical wireless transmissions are among most secure connectivity solutions, regarding network interception of actual physical layer. LightPointe’s optical wireless networking equipment is based on physical layer transport. This white paper discusses security aspects involving physical layer.

Optical Wireless Systems and Network Security

With its cost-effective and high-bandwidth qualities, optical wireless products operating in near infrared wavelength range are an alternative transport technology to interconnect highcapacity networking segments. These optical wireless products, based on free-space optics (FSO) technology, are license-free worldwide. Optical wireless system installations are very simple, and equipment requires very little maintenance. These features make optical wireless solutions appealing to end-users and service providers globally. As a result, number of optical wireless system installations to for enterprise, cellular, and metropolitan area network traffic demands has increased significantly—even during recent telecommunications sector slowdown.

Because optical wireless systems send and receive data through air between remote networking locations, network operators and administrators are naturally concerned about security aspects. One of main reasons for this concern is based on fact that wireless networking solutions is a category in which security and interference problems are very common in radio frequency (RF) or microwave-based communication systems. Such concerns are not valid for optical wireless systems.
