New Features New Features • The main features of ZXG10 B8018 is shown below: • DTRU technology; • DPCT-dual power combining Transmission; • DDT-delay diversity transmission • 4-way diversity reception; • IRC-Interference Rejection Combining; • intelligent power on/off; • IP Abis-interface.
New Features New Features • The DTRU is very flexible and can be used for several purposes . Its two TRXs, for instance, can be used separately (the same with ever)or both,both refers to by DPCT to improve the downlink and by four-way diversity to improve the uplink, they can be configured to create a super TRX.
New Features New Features One DTRU can easily be used to extend coverage
New Features New Features • DPCT---- Dual Power Combining Transmission: • When seeking greater cell range it is crucial to have a strong signal from the BTS to the handset. This is often referred to as downlink capability. This is what a handset presents as signal strength in the display. In configurations intended for maximum coverage, Dual Power Combining Transmission (DPCT) feature doubles the output power from the BTS cabinet, resulting in a significantly larger coverage area.
