Access Unit Installation Guide General Installation GuidelinesBreezeCOM 5• Ethernet cable (straight)3. General Installation GuidelinesFollow these guidelines when selecting the locations for the indoor unit and theoutdoor units:• Select an appropriate location for the Outdoor unit and the antenna (notsupplied by BreezeCOM). The antenna should be mounted on a pole andshould be installed where a direct line of sight with the Access Unit/BaseStation antenna can be established.• The Outdoor unit can be pole- or wall-mounted. Its location should beselected to allow easy access to the unit for installation and testing. Theantenna and Outdoor unit should be installed near each other.• The Outdoor unit is designed for operation under outdoors environmentalconditions. However, it is recommended to try to install it in a place whereits exposure to direct sunlight will be minimal.• The unit is designed to withstand rain and humidity. However, it is notdesigned to withstand immersion in water and it should not be installed in aplace where large quantities of water can accumulate.• The maximum length of the Baseband cable, between the Indoor and theOutdoor unit, should not exceed 30 meters.• Select an appropriate location for the Indoor unit. The Indoor unit should beinstalled in a place that is as close as possible to the exit point of the cableconnecting it to the Outdoor unit. The selection of location of the Indoor unitshould also take into account the need to connect it to a power outlet and tothe network.3.1 Antenna DiversityIn applications where no multipath propagation is expected, a single antenna issufficient to ensure good performance levels. However, in cases where multipathpropagation exists, BreezeCOM recommends that two antennas be used. Thistakes advantage of space diversity capabilities. By using two antennas per unit, the
General Installation Guidelines Access Unit Installation Guide6BreezeCOMsystem can select the best antenna on a per-packet basis (every severalmilliseconds).Multipath propagation is to be expected when there are potential reflectors betweenthe main and remote sites. These reflectors may be buildings or moving objectssuch as airplanes and motor vehicles. If this is the case, the radio signal does nottravel in a straight line, but is reflected or deflected off of the object, creatingmultiple propagation paths.When installing a single antenna, modify the transmit diversity option to eitherantenna 1 or antenna 2, according to the antenna being used (refer to page 17).3.2 Installation OverviewNote: It is highly recommended to complete configuration of the systemparameters in a lab prior to the installation. Refer to page 14 forinstructions on those settings.The typical installation scheme is depicted in Figure 2. The installation processshould follow these general steps:1. Mount the Outdoor unit. Mount an external antenna. Connect the Outdoor unitto the antenna. Connect the Baseband and ground cables to the Outdoor unit.2. Mount the Indoor unit. Connect the Baseband cable (from the Outdoor unit).Connect the Indoor unit to the AC mains via the power cable.3. Connect an ASCII terminal to the MON port of the Outdoor unit via thetechnician cable and configure basic system parameters.4. Verify correct operation of the Outdoor unit.5. Connect the Indoor unit Ethernet connector to the network using a straightEthernet Cable.Note: The Indoor unit should be connected to the power source only after theOutdoor unit have been connected to it.
