Dear Sunshine, 

thank you very much for your confirmation. If this archer NX200 can really merge 5G and 4G together then I would be a happy customer. 

Sim card that I will be using in the modem has speed limited to 150 Mbps (the limit is somewhat flexible so it can go +15% faster) so combining 5G (N28 gives me around 40-60Mbps) and 4G together (B1+B20 gives me 50-90 Mbps)  would optimaly utilize the sim card´s tariff   

Currently the BTS tower servicing my location has 5G (N28) and 4G in B1, B3 and B20 variant. 

I guess my other question would be : How many frequencies can Archer nx200 combine together ? I found out it has 8 antennas 2x2 mimo (I dont know how many antennas are 5G and how many 4G) so it can combine 4 channels together? 

Archer Nx200 has also externall antenna slots which I would use with external antenna - I also dont know if those externall antenna slots support low frequencies (in my case 700-2100) 

I was testing my expensive Zyxel nr7101 there which I took for testing from another property and it was able to aggregate 3 frequencies: N28 + B1+B20.  B3 signal was propably too weak so the modem choosed B20 instead. 

Thank you for more clarification on this.

I think NX200 utilising Mediatek T750, spec says LTE 5x and 5G 2x

@Sunshine

I am using NX200 in KSA with STC network. Speed varies 10-600mb. No merging of 4G and 5G.

Samsung M23 (Qualcomm 750G) CA on B1,B3,B28 for LTE in 5G/4G/3G mode, I see only B3,B1 on NX200.   Activating only 4G mode I can see B28,B3,B1,B3.
