General Chapter 4 . Figure 4-15: Transmission Power and Antenna Parameters The choice of Tx power, antenna gain and cable loss determines the EIRP and is affected by such considerations as radio limitations and regulatory restrictions. Before proceeding to antenna installation details, the following background information should be considered: General Each RADWIN 1000/2000 ODU is made of two radio transceivers (radios).
Single Antennas at Both Sites Chapter 4 For example with a dual antenna RADWIN 1000/2000 can transmit at modulation of 64QAM and FEC of 0.83 and get an air rate of 130 Mbps, compared to 65 Mbps with single antenna. To work in this mode, each antenna port must be connected to an antenna, the RSS level in both receivers should be balanced and a minimal separation between the antennas must be maintained. (For example, by using dual polarization antennas a cross polarization separation is attained).
Considerations for Changing Antenna Parameters Chapter 4 The rates used by RADWIN 1000/2000 are shown in Table 4-5 below: Table 4-8: RADWIN 1000/2000 Transmission rates Radio Modulation FEC Air-Rate [Mbps] Single BPSK 1/2 6.5 Single QPSK 1/2 13 Single QPSK 3/4 19.5 Single 16QAM 1/2 26 Single 16QAM 3/4 39 Single 64QAM 2/3 52 Single 64QAM 3/4 58.
Considerations for Changing Antenna Parameters Chapter 4 maxODUTxPower denote the maximum Tx Power of the ODU, itself depending on the air rate used. Then, the following relationship must be satisfied: maxAllowedTxPower ≤ min(maxRegEIRP – AntennaGain + CableLoss, maxRegTxPower) ... (*) These parameters are controlled as follows: ¾ To set Tx power and configure antennas: 1. Click the Configure buttons in turn to configure the antennas on both sides of the link.
Considerations for Changing Antenna Parameters Chapter 4 3. Set the Antenna Gain and Cable Loss. If do this you will receive a warning message: Figure 4-17: Antenna parameters change warning Note • The Max EIRP level will be automatically set according to the selected band and regulation. • The EIRP level is the sum of the System Tx power and the Antenna Gain minus the Cable Loss.
Installing the Link: Step 5, Services Chapter 4 • Required Tx Power (per radio) will be adjusted down to the lesser of the value entered and maxAllowedTxPower • TxPower (system)is maxAllowedTxPower + 3 (for 2 radios) • Max EIRP is maxRegEIRP. • EIRP is maxAllowedTx Power + Antenna Gain - Cable Loss The table in figure 4-18 only shows rates where the maximum Tx Power is the limitation, rather than regulations. Recall that maxAllowedPower and maxEIRP are regulatory.
Installing the Link: Step 6, Installation Summary and Exit Chapter 4 For version 2.1, Ethernet Only is the only available service. You may choose a specific modulation rate or use Adaptive. ¾ To choose a modulation rate: 1.Choose Adaptive or one of the available rate (see page 1-3 for information about Automatic Adaptive Rate). 2. Click Next to continue.
Installing the Link: Step 6, Installation Summary and Exit Chapter 4 The main window now reflects the installation: Figure 4-21: Main window of the manager after installation ¾ To verify the installation: • Verify that the Radio Signal Strength (RSS) is according to expected results as determined by the Link Budget Calculator.
