Specifications
 When configured with an LMPT:BBU3900: 18 cells
(2T2R/4T4R, 5/10/15/20 MHz) or 12 cells (8T8R, 10/15/20
MHz)
 When configured with a UMPTa/UMPTb:36 cells (2T2R/4T4R,
5/10/15/20 MHz) or 18 cells (8T8R, 10/15/20 MHz)
 When configured with a UMPTe:72 cells (2T2R/4T4R,
5/10/15/20 MHz or 8T8R, 10/15/20 MHz)
 Downlink data rate at the Media Access Control (MAC) layer:
284 Mbit/s (SA2, DL 4x4 MIMO base on TM3 or TM4,
UBBPd/UBBPe，DL 256QAM)

Uplink data rate at the MAC layer:
40 Mbit/s (SA1, UL 2x8 MU-MIMO, UBBPd)
27 Mbit/s (SA1, UL 2x8 MU-MIMO, LBBPd)
 When the UMPTe2 is used, sum of uplink and downlink data
rates at the MAC layer is 10 Gbit/s.
