Introduction 1.1 About Celletras TDA System Celletra Transmit Diversity (TD) technology for CDMA signals enhances the forward link performance by improving the transmit power management, reducing blocking rate, and increasing capacity. The TD technology is available as an add-on to existing (legacy) base stations. In this case, separate components are added to an existing cell site to enhance the performance that can be achieved by the cell site alone on a per-sector basis. This overview of the technology will provide some insights regarding how the TD solution can be applied to a cell site to enhance capacity performance at the site. Add-on Transmit Diversity (TDA) provides for redundant replicas of transmitted signals (from the base station) by transmitting the same information over two or more antennas, providing independently faded channels between the BTS transmit and mobile receive antennas. In order to maintain the total transmitted power (or EIRP), each of the two base station transmit antennas in a TDA system has to transmit a minimum of 50% of the power from a conventional one transmit antenna system. Alternatively, higher power may be transmitted in addition to diversity gain by the two antennas (main and diversity). In this case, the cell footprint in the Down-
link will increase, or (after down-tilting the antennas) the same coverage with higher capacity is obtained. The TDA system reduces the per-link-power required for the mobile station (phone). Moreover, reducing the blocking-rate and access-failures improves the cell forward
(FWD) link capacity. As a result, in FWD link limited sites, sector erlangs increase. The TD process is carried out only at the base station; no modifications are required at the mobile handset. This gives TDA a clear advantage over other transmit diversity schemes such as OTD and STS which require new chipsets to be included in the mobile handset.

Find a calibrated Tx test point to measure the BTS output power (Tx, Down-link). Measure the BTS power and record it including the date and time. If such a calibrated test-point does not exist, refer to 2.5.4. The Traffic load should be taken into account while setting up the TDA system. Allow a suitable power margin for possible load rise. In any case, refer to the measured pilot power as the sector reference level. The pilot power is usually fixed. Add 7.5dB to this level to estimate the maximal Tx power of the sector. Record the above main Pout max. as "Main Path Power Before TDA System" in Appendix C. 2.3 Run Sweep Test Before installing the cables in the system, run a sweep test of all RF cables and record the cable loss (see Table 2-4 for RF cable list). Perform the sweep test using a Time-Domain Reflectometer or a Network Analyzer. Record these parameters for each RF cable:

Document No. 913004500 Rev. 0.0 4-6 Celletra Proprietary Transmit Diversity Add-On System 4.3 Calibration Assembly and Operation Manual This section describes the calibration procedure for the Transmit Diversity (TDA) system. The objective of this procedure is to set the Tx power correctly in the diversity path in respect to the main path, after the TDA system installation. The TDA system calibration refers to the two transmission branches:
Main Tx Diversity Tx The Transmit Diversity mechanisim functions best with equal radiated power from the main and diversity antennas. Moreover, the TDA system enables the overall Tx power transmitted by the two transmission paths (main and diversity) to be higher than that of the legacy BTS Tx power. The overall sector power with the TDA system (including main and diversity) is determined by the operator according to network planning. Once the main path is calibrated by adjusting the BTS output power, the power to the diversity transmit antenna is calibrated by adjusting the digital controllable gain of the TDA Unit via the TSM software. NOTE: All of the steps in the following calibration procedure are on a per sector basis. Repeat all the steps for other sectors with the TDA system, where applicable. 4.3.1 Main Tx See Figure 4-8. Set the BTS output power as follows:
1. Verify that the station is transmitting. 2. Calculate Pout max. as per Section 2.5.4. 3. Record the main Pout max. as "Main Path Power with TDA System" as in Appendix C. NOTE: The calibration procedure involves just gains in Main and Diversity branches. The power is recorded for reference only.

Antenna Power [dBm] = Amplifier Power [dBm] Cable Loss [dB]
Where the cable loss is a positive value in dB. Document No. 913004500 Rev. 0.0 4-8 Celletra Proprietary Transmit Diversity Add-On System Assembly and Operation Manual Figure 4-9 TDA System: Number, Name, and Type 4. Get the main and diversity antennas and the coax cables data from the cable shelf to the antennas. Look for the details belo:
Cable types and lengths RF attenuations at operating frequency [dB]
Antenna types [verify that both sector antennas are isentical]
5. Measure the RF loss for the main and diversity paths according to. Main path loss = W2 + LG1+LG2 A Diversity path loss= W2+Coupler Loss (30dB) + W3 + Att loss (20dB)+
+W5+LG3 B Comments:
1. All losses (W2 W5, LG1 LG3) are positive values in dB 2. If adapter is used instead of W2 the loss is negligible 3. Coupler insertion loss is negligible 6. Calculate the TDA required gain (Downlink Gain [dB]) according to:
Set Gain [dB] = B A 7. Set the Set Gain integer value in the Ststus and Control screen rounding up (B A). 8. Record the above Gain as " TDA Unit Downlink Gain Setting" in Appendix C.

(Check AC or DC input voltage). Check RS-232 cable connection; verify serial comm. port definition on the TSM software. Check communication cable (For connector pin out refer to Appendix B). Check the PC serial port. Low/No RF Power Operate TSM software and check the following parameters:
DC power level in the TDA System setup In/Out RF power If the input seems OK yet the output is faulty, replace the unit and re-
configure the system setup. 1. In the Configuration screen, look for alarms in the unit, where the frame may be colored red or yellow. 2. Drill down to the unit that shows a red or yellow frame. 3. If the PA is OFF, try to turn it ON. 4. If the PA does not go ON, replace the TDA unit.
