  • Page 11: Product Description

    1.1 PRODUCT DESCRIPTION This manual presents installation and operating instructions for the MDS entraNET 900 system. It is for use by professional installers who are expected to install, operate, and perform basic maintenance on the system. The MDS entraNET 900 system is an easy-to-install wireless solution that supports long range Serial and Ethernet data transmission at speeds up to 115.2 kbps.

The MDS entraNET 900’s design makes the installation and configura- Transceiver Features tion easy, while allowing for changes in the future.

  • Page 13: Model Offerings

    1.1.1 Model Offerings The MDS entraNET 900 comes in two primary models—an Access Point and a Remote. In addition, two types of Remotes are available— an Ethernet Remote, and a Serial Remote. Table 1-1 summaries the dif- ferent interface abilities for each type.

  • Page 14: Multiple Protocols And/Or Services

    By using a single AP the cost of infrastructure deployment is cut in half, with only one antenna, one feedline, and one lightning protector required. Other cost reductions come from the system as a whole, MDS entraNET 900 System Guide (Preliminary) MDS 05-4055A01, Rev. A...

  • Page 15: Upgrading Older Wireless Network With Serial Interfaces

    MDS entraNET 900 equipment—more flexible serial and Ethernet interfaces, and higher data throughput. MDS entraNET 900 units are well suited to replace leased or dial-up lines, or existing 900 MHz data transceivers by taking advantage of the transceiver’s serial and Ethernet interfaces.

  • Page 16: Network Design Considerations

    1.3.2 Protected Network Operation through Multiple Access Points Although MDS entraNET 900 units have a very robust design and have undergone intensive testing before shipment it is possible for isolated failures to occur. Down time can be further reduced by using some, or all, of the following configurations.

    The Network Name and the association process The Network Name is the foundation for building individual MDS entraNET 900 networks. It is part of a beacon signal broadcast by the Access Point (AP) to any Remote units with the same Network Name.

    An accompanying concern becomes the security of the communication infrastructure and the security of the data itself. The MDS entraNET 900 is capable of dealing with many common secu- rity issues. Table 1-2 profiles security risks and how the MDS entraNET 900 provides a solution for minimizing vulnerability.
