Questions about this item

Should I choose the CAT 7 version or a different LTE category for this router?

The RX55 is only offered as a CAT 7 model, delivering up to 300 Mbps downlink and 150 Mbps uplink on supported LTE‑A Pro networks.

What does the CAT 7 rating mean for real‑world throughput on this device?

CAT 7 indicates a theoretical peak of 300 Mbps down and 150 Mbps up; actual speeds depend on carrier signal quality, band aggregation and network congestion.

How does the single Gigabit Ethernet WAN port limit the router’s maximum WAN speed?

The 10/100/1000 Mbps WAN port caps wired WAN throughput at 1 Gbps, so the LTE‑A Pro link will never exceed that physical interface limit.
