3. 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 Corporation 3

4. 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’s AN/WSC-54 (V) XN Interior Shipboard Wireless LAN System, developed by Metric Systems Corporation.  1992-2005 Metric Systems Corporation 4

5. 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  1992-2005 Metric Systems Corporation 5 The functionality of each node can be easily changed to meet network requirements.

6. 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 Corporation 6

7. 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. ** (For details, see http://rtg.ietf.org/wg/manet/rfclisthttp://rtg.ietf.org/wg/manet/rfclist  1992-2005 Metric Systems Corporation 7

8. G H A B C D F E Loss of Hub Example  1992-2005 Metric Systems Corporation 8 Maintenance faults as well as natural and man-made disasters can wreak havoc on broadband communications networks. The SAFARI’s powerful routing algorithms allow you to plan, design and provide robust communications disaster 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.

9. G H A B C D F E Loss of Links Example  1992-2005 Metric Systems Corporation 9 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 from Sites C, D, E and F are now quickly routed through Sites A, B, D, E, F and H.

10. G H A B C D F E I New Node Example  1992-2005 Metric Systems Corporation 10 Creating a network from the ground up, replacing a damaged node, or simply adding a new node is designed to be quick and easy. SAFARI’s SAFARI View configuration tool makes it straightforward. Validate RF paths, erect antennas and set SAFARI to auto-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.
