  • Page 20: Antenna Cables

    Document Number: ZXTxRM-5110m 3.7 Antenna Cables   If you decide to use one of the optional antennas, you will need to select the appropriate cable and connector. It is important to select a cable that matches the radio’s impedance. An impedance mismatch will cause the radio link to become inefficient and could damage the radio.

  • Page 21: Lightening Arrestors

    Document Number: ZXTxRM-5110m Along with the type of cable, you need to select the correct connector. Our product uses an RPSMA Male (plug) connector. Therefore, you will need a cable that has a RPSMA Female (jack) on one end. If you are using one of the optional antennas, you will need an N type Male connector, since these antennas have an N type Female on them.

    Document Number: ZXTxRM-5110m Appendix D – Radio Frequency Basics   Appendix D – Radio Frequency Basics D.1 What is dBm?   Radio Frequency (RF) power is measured in milli-Watts (mW) or, more usefully, in a logarithmic scale of decibels (dB), or decibels referenced to 1 mW of power (dBm). Since RF power attenuates as a logarithmic function, the dBm scale is most useful.

  • Page 160: You Must Consider Rf Noise

    Document Number: ZXTxRM-5110m You can often improve your receive sensitivity, and therefore your range, by reducing data rates over the air. Receive sensitivity is a function of the transmission baud rate so, as baud rate goes down, the receive sensitivity goes up. Many radios give the user the ability to reduce the baud rate to maximize range.

  • Page 161: Remember Your Math

    Document Number: ZXTxRM-5110m Remember Your Math   Contrary to popular opinion, no black art is required to make a reasonable prediction of the range of a given radio signal. Several simple concepts must be understood first, and then we can apply some simple rules of thumb.

  • Page 162: Path Loss Rule Of Thumb

    Document Number: ZXTxRM-5110m Beware leafy greens. While a few saplings mid-path are tolerable, it’s very difficult for RF to penetrate significant woodlands. If you’re crossing a wooded area you must elevate your antennas over the treetops. Industrial installations often include many reflective obstacles leading to numerous paths between the antennas.

  • Page 163: Latency And Packetization

    Document Number: ZXTxRM-5110m While long cable runs to an antenna create signal loss, the benefit of elevating the antenna another 25 feet (7.6 m) can more than compensate for those lost dB. Latency and Packetization D.11   Before you lift a finger towards the perfect wireless installation, think about the impact of wireless communications on your application.
