BS Antenna Patten: 4T8R means 4 branch antenna transmitting and 8 branch antenna receiving.
4T8R can solve the UL limitation problems. The major problem in both mobile and fixed scenarios is UL traffic limitation.
Compare to 4T4R, 4T8R has at least 2.8dB gain, which means 15-25% enhancement in coverage area or 15-25% reduce in BS number.
4T8R which exploits the diversity gain and capacity improvement brought by MIMO & MRC, will provide much better performance. (MRC Maximum Ratio Combining)
2TxMIMO+4Tx CDD + 8Rx MRC is recommended for BERCA
