Conceptual Views of Radio System Usage The AP includes an embedded terminal server that provides access to Remote serial ports using an IP or serial connection at the AP. In this capacity, it acts as a gateway between IP and remote serial devices (thus the name “serial gateway”), or a transparent over-the-air serial-to-serial connection.

On the other hand, TCP services are best suited for applications that do not have a recovery mechanism and must have the guaranteed delivery that TCP provides despite its extra overhead.

  • Page 160: Conducting A Site Survey

    6.1.3 Conducting a Site Survey If you are in doubt about the suitability of the radio sites in your system, it is best to evaluate them before a permanent installation begins. This can be done with an on-the-air test (the preferred method), or indirectly using path-study software.

  • Page 165 For 900 MHz systems with cable runs of less than 20 ft/6m, an inexpensive cable type such as Type RG-8A/U may be acceptable. For longer runs, or for 2400 MHz systems, GE MDS recommends using a low-loss cable type such as Andrew Corp. HELIAX cable.
  • Page 166: How Much Output Power Can Be Used

    6.2 HOW MUCH OUTPUT POWER CAN BE USED? (U.S.A. and Canada, 900 MHz systems) 900 MHz transceivers are normally configured from the factory for +30 dBm (1 W) RF power output. This is the maximum transmitter output power allowed under FCC and Industry Canada rules. The power must be decreased from this level if the antenna system gain exceeds 6 dBi.
  • Page 167: How Much Output Power Can Be Used

    Note that a gain of 6 dB or less entitles you to operate the radio at full power output of 30 dBm (1 W). Table 6-4. Antenna System Gain versus Power Output Setting (U.S.A. and Canada only) Antenna System Gain Maximum Power (Antenna Gain in dBi* Setting...

    2. Subtract the antenna system gain from 27 dBm (the maximum allowable EIRP). The result indicates the maximum transmitter power (in dBm) allowed under the rules. In the example above, this is 19 dBm. 3. If the maximum transmitter power allowed is less than 27 dBm, reduce the transmit power accordingly using the radio menu system ), or introduce Main Menu>Radio Configuration>RF Output Power Setpoint...
  • Page 169: Calculating System Gain

    NOTE: Some EU countries mandate lower power outputs and frequency limitations from those referenced here. For example, in France, the transceiver may only be operated in band C (2.4528-2.4782 GHz) at a power level of 10 dBm. Be sure to check the requirements for your region before placing the transmitter on the air.
  • Page 170: Optimizing Performance

    6.5 OPTIMIZING PERFORMANCE After the basic operation of the radio has been established, you might wish to optimize network performance using some of the suggestions in this section. The effectiveness of these techniques varies with the design of your system and the format of the data being sent. There are two major areas for possible improvement—the radio and the data network.
  • Page 171 • The number of bytes they can fit into a hop, depending on hop time, is: Table 6-1. Number of bytes per hop Hop time (MS) Bytes/hop Included in the byte count is 9 bytes of overhead per packet. So, at 7 ms without FEC, a 1000 byte packet requires 1009 bytes split into 45 bytes/hop, or 23 hops.
  • Page 172: Aiming Directive Antennas For Maximum Rssi

    6.5.2 Aiming Directive Antennas for Maximum RSSI The wireless network integrity depends, in a large part, on stable radio signal levels being received at each end of a data link. In general, signal levels stronger than –90 dBm provide the basis for reliable communication that includes a 15 dB fade margin.

    Upgrade Procedure To upgrade the transceiver firmware file ( ), use the filename.gpk procedure below. 1. Launch a TFTP server on a PC connected either directly or over a LAN to the transceiver Ethernet port ( ). Configure the server to allow downloads from the directory containing the firmware image file.

    same profile. Ultimately, you can upload standardized files into the transceiver to speed up the installation process. You can also upload configuration files into a transceiver to restore the settings of a radio using a previously saved configuration of the radio. This is particularly convenient after finishing a test using some experimental settings.

    The file can then be used as a template to generate modified copies adjusted to match other devices. You can modify the configuration files using a text editor or an automated process (not provided by GE MDS). We recommend that you review and update the following parameters for each individual radio.
