The best way to utilize 5G for primary or secondary WAN connectivity is through a cellular router, or mobile router, that has a 5G and/or 4G LTE modem built into the device. Enterprise routers that have hybrid WAN capabilities can support wired and cellular connection links and also provide Wi-Fi for wireless LAN access. These enterprise routers are useful for the flexibility they provide, especially in branch sites such as stores, restaurants, and offices. In areas where 5G is not yet fully usable, a enterprise router can use 4G LTE with great success, albeit less speed and bandwidth.
