Balance said: Not bad on paper. I expected a 1201 Mb/s link-rate (2x2 MIMO, 80MHz, 1024 QAM), but we got a 1430 Mb/s link rate. This mean 2x2 MIMO, 160MHz (!) but only 64-QAM. Click to expand...

Samsung claims the following specs for the Wi-Fi in the S10 phones which are supposedly using the BCM4375:Who knows what Broadcom used to come up with their 1.429 Gbps PHY rate claim . Possibly some unmentioned non-standard feature enables it. My (complete) guess is that it comes from the Real Simultaneous Dual-Band (RSDB) feature which likely allows the chip to operate a single spatial stream of 802.11ax at 2.4GHz and 5GHz simultaneously.2.4GHz 1x1:1 802.11ax (HE40,256-QAM) ~ 229 Mbps5GHz 1x1:1 802.11ax (HE160,1024-QAM) ~ 1200 MbpsAdding these two PHY rates together gives 1429 Mbps. Few, if any, clients would be able to connect to both bands simultaneously so this speed claim is misleading but that is not uncommon in this industry.This would require that the BCM4375 support 160 MHz channels which Broadcom has not yet claimed. Samsung is only claiming 80 MHz channels, for now, but that may be because they have not obtained/pursued DFS certification for some S10 devices. The FCC documents that I've looked at for some of the S10 devices make no mention of 160MHz bandwidth even if DFS is supported.
