Transmit Diversity Add-On System Assembly and Operation Manual Document No. 913004500 Rev. 0.0 vi Celletra Proprietary System Measurement and Testing Warnings WARNING When testing the units in the lab or during field installation, always practice RF radiation safety rules. It is not recommended for service or lab personnel to work closer than two meters from the radiating antenna surfaces when the TDA system operates. CAUTIONS • Disconnect the AC or DC power to the TDA Unit before any cable is connected or disconnected from the unit. • Always use a DC block device connected to the measuring equipment input or output ports (spectrum analyzer, power meter, or RF signal source), when measuring is performed. • Do not connect or disconnect the coaxial connectors while power is applied to the TDA system. • Do not apply more than 0dBm of RF input power to any RF port of the TDA system, or irreversible damage may occur. • When measuring high power outputs, always verify that the equipment input port is capable of handling the expected output power. • During lab or field tests, with AC or DC voltage applied to the TDA Unit, do not use any mobile transmitters in a range of less than 10 meters from the unit. An unexpectedly high RF power might appear at the output ports, which might in turn damage the measuring equipment connected to that port.

1.1 About Celletra’s 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. 1.2 TDA System Description 1.2.1 Block Diagram Figure 1-1 describes the TDA system. 1.2.2 General Description The Celletra TDA system consists of the TDA Unit and Coupler: The TDA Unit interfaces transparently to the BTS at RF low-power levels. The TDA Unit generates the Transmit Diversity (TD) signals and power-amplifies the TD signals to be transmitted through the Tx-Diversity antenna.

In response to the TCB/CCB review, we need A.S.A.P. the following information: 1. Confirm that the device only operates on the single 881MHz CDMA channel. [David Cahana] The device is specified to operate in the Cellular B-Block, 880-890 MHz. 2. State the nominal bandwidth of the product. [David Cahana] The nominal bandwidth is 10 MHz, but at any given time it will amplify just one CDMA carrier of 1.25 MHz bandwidth 3. Levels of DC voltage and current applied to the RF final amplifying device at rated power (Section 2.1033 (c) (8) of Part 2). [David Cahana] The final amplifying device draws 6 A from +27 Vdc 4. Information concerning tune-up procedure over the power range, or at specific operating power levels (Section 2.1033 (c) (9) of Part 2). [David Cahana] The tune up procedure amounts to an adjustment of the amplifier gain to equate the output power with that of another power amplifier path. The gain adjustment is achieved by digitally controlling a RF variable attenuator. 5. Parts List. See Attached.
