2 The WIMAN Command Line Level 1 Introduction to WIMAN technology The WIMAN product series provides a powerful new technology for the design of flexible data networks. Integrating a multitude of innovative and optimized methods and communication protocols, we’ve created a wireless network technology, which is available for various applications such as campus networking, high speed access for Internet users, and cellular data networks in conurbation areas, etc.
2 The WIMAN Command Line Level 1.1 Transmission Speeds / Frequency Range At present, wireless data network technology can be divided into two categories: The first category consists of wireless modems with a small transmission bandwidth. These products are used for company networks, cellular networks, CDPD (Cellular Digital Packed Data) or GSM (Global System for Mobile communication) networks.
2 The WIMAN Command Line Level 1.2 Frequency Hopping Procedure All WIMAN radio modems operate with the modern frequency hopping procedure. With this procedure, the RF-channel is changed in very short intervals (all 8 ms). A total of 80 nonoverlapping radio channels are available. WIMAN takes advantage of these 80 channels, each with 1 MHz of bandwidth, by use of spread spectrum technology (frequency hopping).
2 The WIMAN Command Line Level 1.4 Basic WIMAN Topologies As previously mentioned, the WIMAN technology is not limited to point-to-point connections. Different network topologies can be structured. The following chapter introduces some simple network configurations using the WIMAN units to illustrate some of the features of each configuration. 1.4.
2 The WIMAN Command Line Level 1.4.2 Cellular Networks using WIMAN STAR and WIMAN ACCESS One of the outstanding features of the WIMAN series is its ability to support point-to-multi-point networks with technically matured distribution of load between the individual ACCESS devices (load balancing). Figure 2 shows a typical network environment.
2 The WIMAN Command Line Level 1.5 Transmission Protocols 1.5.1 Frame Relay The WIMAN system supports the Frame Relay protocol widely used at many Telephony companies. It operates smoothly in Frame Relay networks and enables the application of commercial Frame Relay compatible Router as switches on the STAR- and the ACCESS side. Except for the supply of an Internet access, it is additionally possible to use the WIMAN Frame Relay system for telephony uses.
2 The WIMAN Command Line Level 2 The WIMAN Command Line Level The operating system of the WIMAN radio modem has an integrated command line interpreter ("Shell") for configuration of the WIMAN. Input and output is visible on the input or outputwindow of a PC terminal program (e.g. TELIX, ZOC). So that communication between the terminal program and the WIMAN can take place, the communication parameters of the terminal program and the WIMAN must correspond.
2 The WIMAN Command Line Level 2.2 Passwords Passwords serve to protect the WIMAN from unauthorized access to the command line level in the different authorization levels. All passwords must have a length from four to eight characters. For the passwords the following characters may be used: " a... z ", " A... z ", " 0... 9 ", " - ", " @ ", "?", " \ ", " [ ", " ] ", " < ", " > ". NOTE: The WIMAN DOES acknowledge case sensitivity characters for passwords.
2 The WIMAN Command Line Level 2.3 Operation Modes On the command line level, the following operating modes are differentiated with respect to each authorization level: • Command mode and • Configuration mode. In command mode you can view the accepted parameters of the present configuration (current config) as well as give the accepted commands for this mode and authorization level (see Chapter 2.6.1 on page 25).
2 The WIMAN Command Line Level 2.4 Configuration Data The configuration data (values of the adjustable parameters) is classified into the following three types: • New configuration (new config), • Present configuration (current config) and • Non-volatile configuration (boot config). Figure 5 shows the connections of the three different types of configuration data.
2 The WIMAN Command Line Level 2.5 Configuration Parameters The WIMAN radio modems are delivered with a factoryinstalled standard setup. To adjust the WIMAN to your specific requirements you can modify different parameters (depending on the authorization level). The configurable Parameters are classified into the following groups: • Parameter for the wireless interface, • Parameter for the serial interface, • Parameter for the network, • Other parameters.
2 The WIMAN Command Line Level FTabMode LoopData LoopMode The user-defined hopping pattern must be switched on with FtabMode set to USER. Authorization Level: 2 Preset value: System Scope: System, User The parameter LoopData sets the hexadecimal value to be sent in a LoopTest. Authorization Level: 2 Preset value: FFFFFFFF Scope: 00000000 … FFFFFFFF The parameter LoopMode determines, which bit pattern and frame lengths are to be used with the independent back loop test (see loop test below).
2 The WIMAN Command Line Level LoopTest MaxRetry NetId The parameter LoopTest yields a back loop test. If loop test is set to True, the WIMAN begins to transmit test data in back loop operation. Therefore, it is possible to check procedure statistics during the test. This parameter is not available on STAR devices. Authorization Level: 2 Preset value: False Scope: True, False The parameter MaxRetry determines the maximum number of a repeated package dispatching.
2 The WIMAN Command Line Level would function perfectly and all other devices with the same NetId and NodeId would be ignored. RadioPower Antenna Region Authorization Level: 1 Preset value: 0 (WIMAN Star) Scope: 0 ... 250 The parameter RadioPower activates the normal operation or switches into a low power mode (around 0 dBm, regardless of the Region or Antenna setting).
