  • Page 13: Product Overview And Applications

    1.2 Product Description The GE MDS iNET 900 transceiver (Figure 1-1) provides an easy-to-install wireless local area network (WLAN) service with long range and secure operation. It supports both Ethernet and serial data interface options at over-the-air data speeds of up to 1 Mbps (iNET-II) and 512 kbps (iNET).

  • Page 14: Secure Operation

    Secure Operation Data network security is a vital issue in today's wireless world. MDS iNET Series radios provide multiple tools to help you build a network that minimizes the risk of eavesdropping and unauthorized access. Some are inherent in the radio’s operation, such as the use of 900 MHz spread-spectrum transmissions; others include data encryption, enabling/disabling remote access channels, and password protection.

  • Page 15: Model Offerings

    The MDS iNET and MDS iNET-II transceivers are not over-the-air compatible. NOTE: The radio does not support the simultaneous use of Fragmentation and Encryption. If encryption is enabled (other than RADIUS), the fragmentation option will not be available. 05-2806A01, Rev. L MDS iNET Series Reference Manual...

  • Page 16: Mds P21 Protected Network (Redundant) Configuration

    1.2.4 MDS P21 Protected Network (Redundant) Configuration For mission-critical applications, GE MDS also offers the Protected Network Station. This radio incorpo- rates two iNET Series transceivers, two power supplies, and a switchover logic board that automatically selects between Transceiver A and Transceiver B as the active radio. Figure 1-2 shows a view of the pro- tected chassis.

    TransNET and others. In the case of radios using a single port for data and diagnostics, the capabilities are doubled. The data streams are delivered to an IP socket in an application, or in serial format using the Access Point. See Figure 1-5 on Page 6. 05-2806A01, Rev. L MDS iNET Series Reference Manual...

  • Page 18: Multiple Protocols And/Or Services

    Other cost reductions come from the system as a whole, such as reduced management requirements. And above all, the radio offers potential for future applications that run over Ethernet and IP, such as video for remote surveillance. MDS iNET Series Reference Manual 05-2806A01, Rev. L...

  • Page 19: Wireless Lan With Mixed Services

    Millions of wireless data products have been sold in the last two decades for licensed and license-free oper- ation, many of them manufactured by GE MDS. There are several ways that these systems can benefit from incorporating iNET equipment. The chief advantages are interface flexibility (serial and Ethernet in one unit), and higher data throughput.

    1.4.2 Protected Network Operation using Multiple Access Points Although GE MDS transceivers have a very robust design and have undergone intensive testing before being shipped, it is possible for isolated failures to occur. In mission-critical applications, down time can be virtually eliminated by using some, or all, of the following configurations: 05-2806A01, Rev.
