O Series Data Radio – User Manual Part D – System Planning and Design Part E – System Planning and Design Obstructed Radio Path Understanding RF Path Requirements This path has an obstruction that will seriously degrade the signal arriving at the field site. A radio modem needs a minimum amount of received RF signal to operate reliably and provide adequate data throughput.
O Series Data Radio – User Manual Effect of Earth Curvature on Long Paths This path requires greater mast height to offset the earth curvature experienced at such a distance (73km). Part D – System Planning and Design Selecting Antennas Antennas There are basically two types of antennas – omni-directional and directional. Omnidirectional antennas are designed to radiate signal in a 360 degrees segment around the antenna.
O Series Data Radio – User Manual Part D – System Planning and Design Antenna Placement RF Feeders and Protection When mounting the antenna, it is necessary to consider the following criteria: The antenna is connected to the radio modem by way of an RF feeder. In choosing the feeder type, one must compromise between the loss caused by the feeder, and the cost, flexibility, and bulk of lower loss feeders.
O Series Data Radio – User Manual Part D – System Planning and Design Power Supply and Environmental Considerations Power Supply The power supply should provide a clean, filtered DC source. The radio modem is designed and calibrated to operate from a 3.3VDC and 5VDC regulated supply. The power supply must be able to supply sufficient current to provide clean filtered DC under the full current conditions of the radio modem (i.e. when transmitting full RF power).
O Series Data Radio – User Manual Part E – Getting Started- O Series Part F – Mounting and LED Indicators Mounting The O Series radio module is designed to be mounted onto a pcb. Note: In high power or high temperature applications, it is desirable to mount the module such that maximum conducted heat ventilation for the heat sink.
