Going Wireless

Today, Ethernet connectivity and Internet networking are the standards of business and industrial communications.

Broadband wireless networking technology, with its inherent flexibility, affordability and ease of installation, is increasingly displacing wire and fiber for in-plant and critical wide-area commercial and industrial communications infrastructure applications.

Intelligent blending of wireless and wired transport facilities provide a superior solution, balancing cost, performance, reliability and security.

Increasing Productivity, Decreasing Costs

1992-2005 Metric Systems Corporation3

Introducing the SAFARI Wireless Networking System

For terrestrial private wireless network applications to gain acceptance, next generation equipment and systems must provide the following:

Service and reliability levels equal to or better than wire and fiber

Accommodation of the licensed and unlicensed spectrum requirements

An ability to economically meet increasing demand for bandwidth and reliability

Low cost integration path to network legacy components and systems

The SAFARI was developed to provide highly reliable broadband communications in high-stress situations*.

* The SAFARI Srx-54 is the commercialized version of the US Navy’sAN/WSC-54 (V) XN Interior Shipboard Wireless LAN System,developed by Metric Systems Corporation.

The SAFARI Family of Wireless Networking Products

The SAFARI multi-radio solution enables a tailored approach to building industrial ad hoc mesh networks. Our product line includes four basic channel configurations available in any mix of 900 MHz, 2.4 GHz, 4.9 GHz and/or 5.8 GHz.

The three-radio SAFARI Srx-54 hub / relay / access point

The SAFARI dual-radio hub / relay / access point model

The SAFARI single-radio access point / client model

These configurations can be mixed to create highly reliable, broadband redundant networks.

Typical configurations

The functionality of each node can be easily changed to meet network requirements.

SAFARI Technology Core

SAFARI moves beyond consumer-based IEEE 802.11 a/b/g systems by integrating the technologies required to optimize industrial wireless network performance by providing:

Minimum one-way and round-trip latency for time-critical applications

Sustained high-bandwidth for remote programming and streaming video applications

Optimized latency for quality voice networks

Redundancy options for critical high-value applications

Support for non-IP equipment to Net-Centric operation

Robust suite of wireless security capabilities and features

1992-2005 Metric Systems Corporation6

Introducing the SAFARI Wireless Networking System

SAFARI creates true constant bandwidth ad hoc mesh* networks by using a proactive MANET** routing core. The SAFARI MANET routing algorithm allows you to continue operating after multiple levels of link and site failure. Click below for examples of SAFARI’s alternate routing capabilities.

*In a true wireless ad hoc mesh network, there are at least two different pathways to every other node. In a fully mesh network,every node can connect to every other node. This connection can be a direct wire, a single radio link, or multiple links (hops)through multiple routers. The Internet is an example of a fully mesh network.

Loss of Hub Example

Maintenance faults as well as natural and man-made disasters can wreak havocon broadband communications networks. The SAFARI’s powerful routingalgorithms allow you to plan, design and provide robust communicationsdisaster recovery scenarios to sustain operations.

The example above illustrates the loss of Site H and how communications traffic is redirected through Sites A and G.

Loss of Links Example

1992-2005 Metric Systems Corporation9

Although a well designed wireless system can be as reliable as wire and fiber, equipment failure and severe interference can cause a decline or loss in service. The SAFARI’s full bandwidth ad hoc mesh networking capability detects link loss and degradation and automatically reroutes traffic, maintaining operation.

In this example, wireless links between Sites C and D and Sites C and G are out of service. Traffic destined for Site G fromSites C, D, E and F are now quickly routed through Sites A, B, D, E, F and H.

New Node Example

1992-2005 Metric Systems Corporation10

Creating a network from the ground up, replacing a damaged node, or simply addinga new node is designed to be quick and easy. SAFARI’s SAFARI View configuration toolmakes it straightforward. Validate RF paths, erect antennas and set SAFARI toauto-configure and SAFARI will automatically search out paths and establish network-wide connectivity.

In the example above, new Site I actively searches for adjacent or designated nodes to establish connectivity with the total network.
