The BL1000HW will be used to provision KDDI's au Hikari ("light") home 10 Giga and 5 Giga services. The draft 802.11ax gateway is built on Qualcomm's IPQ8072 chipset and supports 4 streams in 5 GHz and 4 in 2.4 GHz. 1024 QAM modulation is supported on both bands, which yields maximum link rates of 1000 Mbps in 2.4 GHz and 2165 Mbps in 5 GHz.
The IPQ8074 announced in February 2017, has an 8 stream 5 GHz and 4 stream 2.4 GHz radios. Both SoCs share the same compute core, which has four A53 64 bit cores clocked at 2.2 GHz. Both IPQs also have many microcoded accelerations that helps keep up with a 10 Gbps WAN connection.
The LAN side has one 10 Gbps /5 Gbps /2.5 Gbps / 1 Gbps / 100 Mbps port and three standard gigabit Ethernet ports. There is a version of the BL1000HW described here that has a 10/5/2.5/1/0.1 G port in addition to the version that has a fiber port.
Other features include support for the latest WPA3 wireless security standard and 8x8 MU-MIMO sounding. 8 stream sounding is an 802.11ax option that is intended to simultaneously support up to four 2x2 MU-MIMO devices in 8 stream designs vs. only two 2x2 devices using 4 stream sounding.
Although the KDDI router supports only four streams, it can understand MU-MIMO sounding from devices supporting 8x8 sounding and choose the best four of the eight.
Even though the current installed base of MU-MIMO devices will work with this new router, they won't support 8 stream sounding. However, Qualcomm says it is adding this capability to all its new 802.11ac devices shipping this year.
Of course, taking advantage of draft 802.11ax' full feature set requires draft 802.11ax devices. Qualcomm has a chip for that in the form of its WCN3998, announced at this year's Mobile World Congress in February. The chip is a 2x2 draft 11ax device supporting 8 stream receive sounding and WPA3 security. It is supposed to start sampling next quarter, with first devices starting to appear early in 2019.
Aside from draft 11ax bragging rights, the practical value in using Qualcomm's IPQ407x platform comes from its compute power that can cost-effectively support 10Gbps service and its implementation of WPA3.
