When evaluating routers for B2B procurement, prioritize Wi-Fi 6 (802.11ax) or Wi-Fi 7 standards to ensure high-speed data transmission and lower latency. Key metrics include Concurrent User Capacity (look for devices supporting 100+ connections for office environments), Dual-band or Tri-band support (2.4GHz, 5GHz, and 6GHz), and Gigabit Ethernet ports (WAN/LAN). For industrial applications, ensure the device has a ruggedized metal casing and supports a wide operating temperature range from -40°C to 75°C.
