Basic Functions
The ZXSDR R8862 supports the following functions:
Supports DD, 900 MHz, 1800 MHz, and 2100 MHz frequency bands.
Supports a UMTS channel spacing of 5 MHz, 4.8 MHz, 4.6 MHz, 4.4 MHz, and 4.2 MHz.
Supports scalable LTE bandwidth configurations such as 1.4 MHz, 3 MHz, 5 MHz, 10 MHz, 15 MHz, and 20 MHz defined in 3GPP.
Supports two-way transmitting and two-way receiving.
Supports 256QAM modulation in LTE downlink and 64QAM in uplink.
Supports RTWP report interval at 100 ms and 2 ms.
Supports transmit power reporting function for every carrier.
Supports the overload protection function for the power amplifier.
Supports the measurement, compensation and adjustment functions for channel delay.
Supports dynamic PA voltage adjustment to achieve the best efficiency in different system loads.
Supports the transmit channel switching on/off function.
Prevents connected RRUs and the running BBU from being affected in case of an R8862 software failure.
Supports the built-in lightning protection function for the DC power supply.
