Zyxel LTE7480 wrong specs in Zyxel website

John Blackrock

Zyxel website (https://www.zyxel.com/products_services/4G-LTE-A-Outdoor-Router-LTE7480-M804/specifications) claims LTE7480-M804 to be Category 12 device but at the same time saying that 2CC with 4x4 MIMO is supported. But 8 streams is not possible with Cat12.

LTE Interface

• Standard compliant: 3GPP UE Category 12
• Support LTE bands : 1/3/5/7/8/20/28/32/38/40/41
• Support DL TM1/2/3/4/7/8/9
• LTE Antennas: 4 embedded directional antennas of up to 7 dBi/element (4x4 MIMO)
• Support DL 2CC, 4x4 MIMO, 4 spatial streams
• Support DL modulation QPSK, 16-QAM, 64-QAM and 256-QAM
• Support UL modulation QPSK, 16-QAM and 64-QAM

Furthermore, overview page also advertising: 
"The Zyxel LTE7480-M804 4G LTE-A Outdoor Router employs 3GPP UE downlink Category 12 – the best-practice LTE technology with downlink data rates of up to 600 Mbps through 4 Spatial Streams on two component carriers."

Either the device can do 4+2 streams with 256QAM or 4+4 streams with 64QAM (unlikely as 256QAM is supported). Btw, quite disappointing if device has no 3CA support with 2x2 MIMO.

Could you please correct your website with correct information as now it is false regarding to the stream support at least in two different pages?
