Cost Effective Wireless Solution

Compare a traditional X.25 wired solution to an MDS TransIt™ wireless network alternative. Cost savings and efficiencies are obvious once you understand how the system works.

GE MDS is a world leader in wireless data networking solutions with applications in the SCADA, telemetry, telecommunications, and on-line transaction processing markets.

The topologies for these systems involve links between several remote PCs. In a typical access configuration to an X.25 network, one dedicated line is required for each remote point, as well as one port. The X.25 operator charges for each port at the node, and customers additionally pay for communication links required to access the node (private lines). TransIt has the ability to distribute several circuits (permanent or switched) from a single X.25 node to several remote stations, as shown in the TransIt configuration. The connection with the service provider is through a single port at the access node. TransIt replaces all private lines required to access the service node, offering ongoing savings. Also, the tariffs paid, based on the number of ports used at the access node, are reduced. The NM-100 Master Station performs all the functions of the X.25 switch, thus eliminating the need for this equipment.

Additionally, MDS TransIt provides a Network Management System (NMS) to effectively control and monitor each component on the TransIt network. It provides a complete profile of the system, fault management, system configuration, performance management, and system security.

TransIt Wireless Network Advantages:

• Reduced cost-of-ownership, no ongoing private line cost
• Business-rated reliability, ISO 9001-certified
• TransIt's architecture supports redundancy
• Ease of integration -TransIt is compatible with standard protocols and offers the most comprehensive suite of protocols
• Rapid deployment -enhances revenue potential
• Excellent flexibility to incorporate both licensed and license-free (spread spectrum) radios in one integrated system
• Efficiency - TransIt operates on a single frequency, allowing you to double the number of networks running on existing frequency pairs, or cut in half the expense to acquire frequency pairs
• TransIt offers a complete family of radio platforms (licensed, 200 MHz - 900 MHz and license-free, 900 MHz)
• Eliminates the need for equipment to support X.28/X.3 PAD and end-to-end modems
• Low-cost "last mile" implementation to provide customer service
• TransIt offers excellent flexibility to migrate from one protocol to another (change from x.25 to IP) without incurring hardware cost
