They are ideal for connecting locations that cannot be networked via wired DSL. Furthermore, the models equipped with 3G/4G systems and ADSL/VDSL modems offer the very highest operational reliability thanks to the redundancy they offer - so you get twice the safeguarding with cellular VPN routers from LANCOM. Cellular routers with WLAN provide flexible Internet access via LTE/4G or external modems.
