MDS entraNET Transceiver Models MDS entraNET transceivers use an advanced Media Access Controller Robust Radio Operation (MAC) to ensure network access for stations with data to send. The MAC permits data to be sent from endpoint devices on an on-demand basis, preventing over-the-air data collisions and ensuring that data gets through as intended.

Conceptual Views of Radio System Usage The AP includes an embedded terminal server that provides access to Remote serial ports via 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.

    Most polled protocols are best served by UDP services, as the protocol itself has built-in recovery mechanisms (error correction). UDP pro- vides the needed multidrop operation by means of multicast addressing, where multiple remote devices receive and process the same poll message.

  • Page 154: 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 is begun. This can be done with an on-the-air test (the preferred method); or indirectly, using path-study software.

Antennas are available from a number of manufacturers.
  • Page 159 For 900 MHz systems with cable runs of less than 20 ft./6m, an inexpen- sive cable type such as Type RG-8A/U may be acceptable. For longer runs, or for 2400 MHz systems, we recommend using a low-loss cable type such as Andrew Corp. HELIAX cable.

  • Page 160: 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 supplied from the factory set for +30 dBm (1 Watt) 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 161: How Much Output Power Can Be Used

    gain of 6 dB or less entitles you to operate the radio at full power output 30 dBm (1 Watt). 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 EIRP minus Feedline Loss in dB†)

  • Page 162: How Much Output Power Can Be Used? (Etsi 2400 Mhz Systems)

    1. Determine the antenna system gain by subtracting the feedline loss (in dB) from the antenna gain (in dBi). For example, if the antenna gain is 10 dBi, and the feedline loss is 2 dB, the antenna system gain is 8 dB. 2.

  • Page 163: 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 164: Optimizing Performance

    6.5 OPTIMIZING PERFORMANCE After the basic operation of the radio has been established, you may wish to optimize network performance using some of the suggestions in this section. The effectiveness of these techniques vary 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.

Number of bytes per hop Hop time (MS) Bytes/hop Included in the byte count is 9 bytes of overhead per packet. So, at 7MS without FEC, a 1000 byte packet requires 1009 bytes split into 45 bytes/hop, or 23 hops.

    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 provides the basis for reliable communi- cation that includes a 15 dB fade margin.

This is particularly convenient after finishing a test using some experi- mental settings.

    TERMS AND ABBREVIATIONS 9 Chapter Counter Reset Paragraph 10 Chapter Counter Reset Paragraph If you are new to wireless IP or Ethernet systems, some of the terms used in this guide may be unfamiliar. The following glossary explains many of these terms and is helpful in understanding the operation of the trans- ceiver system.
  • Page 200 DCE—Data Communications Equipment. In data communications ter- minology, this is the “modem” side of a computer-to-modem connec- tion. The transceiver ports are set as DCE. COM1 COM2 Decibel (dB)—A measure of the ratio between two signal levels. Fre- quently used to express the gain (or loss) of a system. DES—Data Encryption Standard.
  • Page 201 FHSS—Frequency Hopping Spread Spectrum. A common transmission technique used by license-free transceivers. Frame—A segment of data that adheres to a specific data protocol and contains definite start and end points. It provides a method of synchro- nizing transmissions. Frequency Hopping—The spread spectrum technique used by the transceivers, where two or more associated radios change their oper- ating frequencies several times per second using a set pattern.
  • Page 202 Latency—The delay (usually expressed in milliseconds) between when data is applied at the transmit port at one radio, until it appears at the receive port at the other radio. MAS—Multiple Address System. A radio system where a central master station communicates with several remote stations for the pur- pose of gathering telemetry data.
  • Page 203 Poll—A request for data issued from the host computer (or master PLC) to a Remote radio. Portability—Refers to the ability of a transceiver to connect to an AP from multiple locations without the need to reconfigure the network set- tings. For example, a transceiver located in one place and connected to an AP can be turned off, moved to another place, turned back on;...
  • Page 204 SWR—Standing-Wave Ratio. A parameter related to the ratio between forward transmitter power and the reflected power from the antenna system. As a general guideline, reflected power should not exceed 10% of the forward power (≈ 2:1 SWR). TCP—Transmission Control Protocol. A “guaranteed delivery” pro- tocol used to set up a connection between two devices with acknowl- edgements (ACK/NACK), and retries if the data is not received properly.
