Beyond simple Point-to-Point and Point-to-Multipoint capabilities, Viper can be configured to act as a wireless repeater, a wireless bridge, or as a wireless router. As a repeater, the Viper will accept incoming traffic and retransmit it without change. This effectively extends the range of a wireless network. As a bridge, Viper will perform a similar retransmission function, with the additional capability to accept incoming transmissions using one protocol, and retransmit them using a different protocol. Finally, Viper can act as a highly sophisticated router, in which the retransmission of the incoming signal can be performed selectively to different target destinations, based an a variety of criteria. Among other things, Viper’s router functionality permits the creation of dynamic multi-hop Store and Forward network topologies.
Each one of us benefits from wireless technology every day. Many of these benefits are obviouss: wireless mobile handsets, network television, set-top satellite communications...the list is long and integral to modern society. But each one of us benefits in less obvious ways as well. Wireless technologies that support our modern infrastructure are not immediately evident to the consumer, perhaps, but they are no less important. Backhaul networks, public safety and first responder support, and Machine to Machine (M2M) communications all serve the technologies that directly serve us. And they are undergoing a transformation every bit as radical and aggressive as the wireless smartphone.
As the size and complexity of any wireless network grows, the ability to centrally manage the network becomes paramount. Calamp answers this requirement with Airboss, the industry’s most powerful and sophisticated private network management system. Airboss provides an intuitive, continuous and rich graphical view to the health of any service-affecting network-attached device, including a wide array of customizable alarms, trends and reports. Airboss is founded on the InduSoft Web Studio Software Suite, and can function as a either a stand-alone or web-based NMS, providing highly-detailed monitoring and management services for both wired and wireless devices, and offering both reactive and proactive management capabilities for optimal network tuning and performance. Airboss is based upon open standard architectures and protocols, and provides for maximum interoperability for both existing infrastructure and greenfield installations. Airboss answers the most demanding requirements for intuitive, accurate visualization of network devices and topologies, and provides cost-effective optimization and management capabilities for the enterprise-wide management of thousands of devices.
Two new security standards have recently entered the wireless networking industry: Wi-Fi Protected Access (WPA) and 802.11i. These new options strengthen and/or replace the existing Wired Equivalent Privacy (WEP) specification, and solve some of today’s security issues. But there are still serious security issues that are not addressed by the standards.
It is exceedingly rare that radio frequency (RF) interference can be eliminated or avoided. Left unchecked, RF interference will greatly decrease the effective throughput of wireless communications. This poses a problem, because in addressing the interference challenge, responsible radio manufacturers realize that one must choose a proper balance between speed and robust RF communications. A less-than-responsible approach would maximize user throughput without taking the necessary precautions and implementing the necessary features to provide robust RF communications. Interference mitigation features, by contrast, can reduce the impact of interference in RF communications. Microwave Data Systems, Inc. (MDS) has deployed hundreds of thousands of radios globally with features that assist in mitigating interference.
Modern organizations of all sizes share common requirements for information technology – the efficient, rapid, secure delivery of applications, files, and content to end users. As these organizations expand, network efficiency naturally emerges as a basic requirement for students, employees, customers, suppliers, and partners. Infrastructure must scale easily to meet peak demands, and costs must be contained. Sluggish networks and poor performance can kill productivity and frustrate network users.
In simplest form, the job of a cache – any cache - is to move data closer to the user. ‘Closeness’ in this case is temporal, rather than physical; it is a measure of time, not of distance. Caches seek to reduce the amount of time that elapses been a request and a response.
Caches are everywhere. Your computer has a memory cache. Your browser has a data cache. Your ATM has a cash cache. The list is endless; caches are a common feature of modern society. Warp Solutions has simply applied the caching model to the complex latency problems that are inherent in modern networking technologies.
All data has an inherent life span; the length of this span is generally referred to as the persistenceof the data. By convention, more persistent data is referred to as staticcontent; less persistent data is called dynamic content. In the real world, however, data persistence exists on a continuum; the distinction between ‘static’ or ‘dynamic’ designations, while not entirely arbitrary, is nevertheless flexible, and dependent upon the business, industry – even the specific network in question.
The explosive growth of Peer-to-Peer (P2P) traffic on both public and enterprise networks around the globe has introduced new challenges for network service providers. P2P traffic represents an increasingly dominant percentage of worldwide data network traffic, and traditional methods of network optimization, which are based on HTTP protocols, are not well suited or even applicable to the alternate protocols used for P2P traffic. As networks become increasingly saturated with traffic that cannot be cached, operational expenses increase, and network performance plummets.
As part of ongoing efforts to upgrade and improve the state of North American Directory Assistance technology, varetis is pleased to announce a new generation of Voice Store and Forward (VS&F) technology, available as part of our Automated Directory Inquiry System (ADIS), the world’s most advanced and robust directory automation solution.
