What is DDT?What is DDT?

What is Four Way Diversity ??What is Four Way Diversity ??

Reducing CAPEXPowerful coverage capability

The big power output helps improve and extend the coverage area of the base station as well as keep the number of sites to the minimum, saving the costs for main equipment and supplementary resources.

Net Speed technology to increase coverage and data qualities

DDT can increase network coverage without increasing power output; improve Mobile Station (MS) receiving sensitivity and network capacity; and reduce the costs of network optimization.

4-way receive diversity can be used to achieve additional uplink gain, and reduce MS transmit power while boosting battery life. Dual Power Combining Transmission (DPCT) is another technique to decrease CAPEX. In the initial network construction period, DPCT can provide about 3dB transmit gain to extend the coverage area; the dual-density TRX can be used as two TRX units to solve the capacity problem as traffic grows.

Summary - Summary -

Powerful Abis interface transmission technologies to save transport resources

Dynamic Abis means that time slots are dynamically mapped between the radio channel and E1 channel at the Abis interface instead of being defined by Operation & Maintenance Center-Radio (OMC-R), thus enabling more efficient use of Abis time slots when packet-based services continue to grow.

Abis compression technology can achieve an industrial leading 15:1 compression ratio, which means one E1 supports 15 TRXs transfers in the Abis interface. (*ring)

Abis over IP enables operators to use IP networks to connect the BSC and BTSs, thereby saving on transport facility and reducing CAPEX. This technique also supports capacity expansion as IP networks offer high bandwidth.

If 4-way receive diversity is performed in conjunction with either the DPCT or DDT technique, a BTS can provide ultra-far coverage area.

Summary – Continued Summary – Continued

Reducing OPEX Lower power consumption and OPEX

For operators, power consumption reduction in base stations is an increasingly important consideration as it means lowered cost, smaller heat dissipation and improved reliability. With no air conditioning necessary and lower power consumption, the ZXG10 8000 series BTSs can decrease site OPEX to new levels.

Small size and light weight, allowing easy installation

Intelligent BTS shutdown

Under low traffic conditions, some TRX units can be shut down to save on power consumption costs. The BTS will detect the power supply, and some TRX units will be closed to extend battery service run time when the remaining battery power is lower than the preset value.

Universal TRX module and control board

DTRU, main control and channel processing modules can be used in both indoor and outdoor BTSs. These universal modules help lower the expenses for spare parts, as well as the maintenance and networking costs.

Output power-ZXG10 8018 supports 40W power for 8PSK and 60W for GMSK

Static sensitivity-the static receiving sensitivity of ZXG10 8018 reaches up to -112 dbm. The high sensitivity guarantees the uplink channel performance and is one of the prerequisites for a wide coverage

RF Indices

Working Modes Work Mode Description

Dual carrier mode No Four-way diversity configuration, no DPCT setting configuration. DTRU can configure both the left and the right sub boards.

Odd carrier modes Odd carrier with 4-way diversity reception

Only configure Four-way diversity. DTRU only configures the left sub board, and the right sub board has no data configuration.

Odd carrier with 4-way diversity reception and DPCT

Four-way diversity plus DPCT. DTRU only configures the left sub boards, and the right sub board has no data configuration.

Odd carrier No Four-way diversity, no DPCT setting. DTRU only configures the left sub board, and the right sub board has no data configuration.

IRC

IRC User can check or uncheck IRC check box depending on actual configuration.
