External antennas that let you improve the signal
The RUT951 has two SMA connectors for LTE and two RP-SMA connectors. Having connectors means the antennas can be swapped, or a cabled external antenna can be fitted when the router sits in a cabinet or in a spot with weak reception. Where 4G is unavailable, the router can fall back to 3G or 2G networks. RutOS is based on OpenWrt, a system that network professionals know well.
