ZXSDR R8860 Technical Manual
The distributed BTS solution of ZTE CDMA2000 BBU+RRU has the following advantages:
•Low labor and engineering expenses.
Its small size and lightness facilitates transportation and engineering installation.
•Low room rent and quick network establishment.
It is applicable to various scenarios. It can be installed on a tower, a building top or a wall. The flexible adaptability facilitates quick network deployment and saves room rents and network operation expenses, taking advantage of Time-To-Market.
•Convenient upgrading and expansion.
It supports multiple carrier sectors. The number of cabinets varies with the actual situation.
•Decrease in the total number of sites.
The RRU can be installed as close to the antenna as possible, which saves feeder expenses, reduces feeder loss, improves RRU on-top output power and increases the coverage.
•Low power consumption.
Compared with traditional BTSs, the distributed BBU+RRU BTS has lower power consumption, which reduces power investment, saves electrical expenses and network operation cost.
•Distributed networking mode.
It supports star and chain networking between BBUs and RRUs, effectively making full use of network resources.
•Advanced universal BTS platform.
The BBU uses a B3G and 4G oriented platform that implements various standards so that a single BTS can support multiple standards. This helps operators integrate multiple BTSs into a multi-mode BTS, simplifying the management of BTSs so that operators can flexibly choose network evolution directions and users can enjoy the transparence and smooth evolution of networks.
1.2Position in the Network
ZXSDR R8860 is an outdoor remote Radio Frequency (RF) unit of ZTE CDMA2000 series. ZXSDR R8860, together with the BBU, constitutes an integrated Base Transceiver Station (BTS). ZXSDR R8860 implements wireless transmission in its coverage area. Figure 1-2 shows the position of ZXSDR R8860 (RRU) in the CDMA network.

1.5 Features
The features of the ZXSDR R8860 are as follows:
•Small Size
The ZXSDR R8860 occupies a small area, saving room rent expenses.
àDimension of a single ZXSDR R8860 cabinet without handle (H x W x D): 500 mm × 320 mm × 172 mm. When installed indoors, it requires a small installation area.
àZXSDR R8860 can also be installed outdoors, supporting pole-mount, wall-mount, and Gantry mount installations. Except for the Gantry mount installation, which occupies minimum floor space, the other cases almost does not occupy any floor space.
•Light Weight
A single ZXSDR R8860 cabinet weighs 22 kg so it is easy to transport and install, requiring low manpower and engineering costs.
•Optical fiber Support
ZXSDR R8860 supports optical fiber installation on a tower. ZXSDR R8860 and the BBU can be connected via fibers. One pair of fibers can support a large number of sectors which greatly lowers antenna feeder cost and engineering expenses
•Low Power Consumption
Lower power consumption imposes lower power supply requirements, saving power construction costs and daily power charges.
àPower consumption: (<350W, -48 V DC)
àLess RF power loss because the installation of ZXSDR R8860 on the tower close to antennas requires a shorter feeder cable.

SJ-20100722143906-001|08/30/2010 |
ZTE Proprietary and Confidential |
ZXSDR R8860 Technical Manual
àHigher power amplification efficiency ( >30%, -48 V DC).
•Natural Dissipation
No heat exchanger is needed when the cabinet is installed outdoors.
•At most 8 carriers x 80 W RF power.
supports various application scenarios including dense urban coverage and wide rural area coverage. It provides diversity reception function and supports transmission diversity and 4-antenna reception by means of cabinet combination.
•Complex Network Application
supports baseband-RF star and chain networks, delivering flexible solutions to complicated network environments.
1.6External Interfaces
The external interfaces supported by the ZXSDR R8860 are located at the bottom of the cabinet.
