Questions about ZTE MF289F

Unfortunately, there is never any useful information at Digitec, and I've noticed that for years. I always do it like this: copy the manufacturer's article number and name or both, then enter them in the Google search and add the PDF. That way I actually get something useful for everything (the good price at Digitec and the details from the internet, that's how I solve it for myself). Even if I think about how much very good information is available from the manufacturer for a smartphone, for example, I would never buy something with the small description from Digitec, because if you're unlucky you can even find incorrect information. I then found information on the model at ZTE Australia, it is apparently a 4G router that can do a maximum of Cat 20 (2Gbit/s download). https://ztemobiles.com.au/4g-mf289f/ I'm curious to see how much information can be copied here, because I found a lot of additional information on another site: Technical specifications of the GigaCube 4G Z21 (MF289FB) Modem features Modem 4G-Cat20 Download up to 2.0 Gbits Upload up to 150 Mbit/s Modulation upload 2CC, 64QAM Modulation download 4x4 MIMO, 4CC, 5CC, 256QAM SIM card slot 1 x Nano-SIM (4FF) Frequency bands LTE B1 (2100), B3 (1800 +), B7 (2600), B8 (900), B20 (800 DD), B28 (700 APT), B32 (1500 L-band) Frequency bands UMTS B1,B8 LAN port / WLAN WLAN standards 802.11a/b/g/n/ac Frequency bands 2*2 MIMO 2.4 GHz & 5 GHz (Wifi 5) LAN standard 10/100/1000 MBit/s LAN ports 2 x RJ-45, 1x WAN switchable Connections 1 x power connector 2 x Ethernet LAN/WAN 4 x mobile radio connection (SMA) 2 x TS9 antenna connection without function 1 x RJ11 telephone connection without function Mechanical data Size 78 x 191.5 x 132 mm (L x W x H) Weight 475 g Operating voltage 12 volts Maximum operating temperature -0° C to 40° C Scope of delivery CAT 20 router with 4 external antenna connections 4 x 2 x 5 dBi rod antennas for standard operation (optional, if selected) Power supply 220 V to 12 V Data cable
