April/May 2015 organizations prefer to deploy private wire- less networks so they can maintain control over network access, traffic, security and capacity while achieving high levels of capacity, redundancy, speed and agility for their mission-critical applications. Network strengths and weaknesses should be carefully evaluated based on connectivity requirements as well as the ap- plications that will need to run effectively on top of the network, both today and as part of future growth. Below are a few of the common types of network options that could be considered in industrial and municipal environments in which mobility must be addressed. Cellular Networks Cellular networks use fixed-location transceivers to create "cells" of wireless coverage over land areas and relay data via handovers to neighboring cells as users travel into new cell geographies. LTE (Long-Term Evolution) LTE (Long-Term Evolution) technology enables wireless communication of high-speed data and was built to increase the capacity and speed of wireless data networks by leveraging new digital signal processing (DSP) techniques and modulations. Satellite Satellite is most often used to provide broadband access in areas with little or no existing network infrastructure. Traditional Mesh Networking Traditional mesh networking creates large-sale, resilient wireless local networks capable of multiple concurrent connections. Each mesh "node'' has redundant links to other nodes, which creates inherent redundancy. Rajant Kinetic Mesh Networks differ from traditional mesh in that they provide extremely scalable, fully mobile-enabled, wide-range, and reliable connectivity, allowing all nodes and clients to be in motion all the time. When need- ed, the network instantaneously redirects data packets over more available frequencies to avoid in- terference or obstructions while as- suring the fastest possible delivery. Rajant Kinetic Mesh enables full network motion and flexibility with no mas- ter or controller node to create a point of failure. Instead, it employs multiple frequen- cies and any-node to any-node capabilities to continuously and instantaneously route data via the best available traffic path and frequency, all with extremely low overhead. A Closer Look at Rajant Kinetic Mesh Technology Unlike any other offering on the market today, Rajant Kinetic Mesh technology pro- vides fully mobile wireless broadband con- nectivity, allowing all nodes to be in motion at any time. While this unique functionality makes it a natural fit for operations with de- manding mobility requirements, it brings an array of other equally compelling techno- logical features for any organization seeking to intelligently connect diverse assets across large-scale environments. These environ- ments may be highly remote and span hundreds of square miles, where existing cellular, 3G or Wi-Fi infrastructure may not yet be established. In those cases, Kinetic Mesh networks can be readily deployed using any number of Rajant BreadCrumb wireless network nodes. Easy-to-install BreadCrumbs rapidly self-configure to route communications peer-to-peer or through any satellite, point-to-point wireless or wired links. In addition to remote locations, Kinetic Mesh performs in high density environ- ments. Many traditional mesh networks become unusable once they reach a set node capacity, which can be as little as 50. However, Kinetic Mesh networks can oper- ate in full form in networks supporting hun- dreds of thousands of nodes. In fact, these networks actually grow stronger as density increases, since new nodes provide additional paths for data routing. In remote or high-density environments, network traffic is orchestrated by Rajant InstaMesh technology. InstaMesh is a patented protocol that dynamically evaluates and determines the best pathways between any References "Gartner Identifies the Top 10 Strategic Technology Trends for 2014", Gartner, 2013 "High Performance in IT: Defined by Digital", Accenture, 2013 "Ericsson Mobility Report", Ericsson, 2014 "Wireless Mesh Networks for Internet of Things Latency", Enterprise Networking Planet, 2014 "Prevent Your Machines Taking Sick Days", Alstom MSc, 2014 "Strategic Opportunity Analysis of the Global Smart City Market", Frost & Sullivan, 2013 (continued from page 1) Network Innovation On the Move Bringing the Private Wireless Network to Life With Kinetic Mesh Technology Kinetic Mesh in Mining Mining operations must monitor and manage large fleets of vehicles, equipment and personnel, all remotely dispersed across rugged terrain- and all of which require constant, reliable high-bandwidth connections while on the move. Continuous production and safety mandates unwavering availability, with 24x7x365 uptime in all areas of the mine. Rajant Kinetic Mesh networks can be easily implemented to reliably cover people and assets across all remote mining operations, even in landscapes where no existing cellular, 3G or Wi-Fi infrastructure is available. Assure IP traffic uptime with virtually no manual intervention, even in extreme conditions. Rajant Kinetic Mesh networks rapidly adapt to changes in network topology, whether nodes are moved, disabled or added. If an obstruction is encountered or interference occurs at one node across the mine, InstaMesh provides smart self-healing functionality by redirecting packets to alternative links in real time. and pumps. Rajant Kinetic Mesh technology helps mine operators reduce downtime by bringing them the data needed to proactively identify maintenance issues and remotely manage equipment health. Rajant Kinetic Mesh technology autonomously optimizes to assure that mining personnel have seamless communications and instant access to critical data and applications, whenever and wherever they need them.
