Ideal for on-site use With the integrated ignition detection, the router can switch itself on or off depending on whether the vehicle is switched on. According to a user-defined interval, the HD4 MBX can be switched off automatically when the vehicle is switched off to protect the battery from excessive discharge. The HD4 MBX also supports the optional SIM injector, which enables connection to a further eight mobile phone providers. This mitigates weaknesses in mobile coverage and ensures consistent connectivity. If your deployment crosses country borders, you can also use the SIM injector to load multiple SIM cards, avoiding roaming charges. Suitable for high particulate environments where other fan-based routers would not hold upPower your IP phones, cameras and access points. Same dimensions as the previous HD4 model, so it will fit seamlessly into any of your previous deployments. Out-of-the-box, the router supports Gigabit LTE. For future technologies, it has an interchangeable cellular module. So if you need to upgrade to 5G, you can simply replace your old module with a new one. In addition, the HD4 MBX is able to achieve a throughput of 2.5 Gbit/s, so you have enough bandwidth for Gigabit Ethernet, 5G or future cellular technologies. Speed and reliability through SpeedFusion™ SpeedFusion allows users to combine any number of connections into a point-to-point connection to achieve what others cannot: Combine the bandwidth of multiple mobile connections into one ultra-fast data connection. Accomplish bandwidth-intensive and latency-sensitive tasks without a landline. HOT FAILOVER Hot Failover maintains secure tunnels across all available WAN connections to keep the network up and running if one connection fails. Should a WAN connection fail, SpeedFusion immediately routes traffic to a working tunnel for uninterrupted VoIP sessions. CARRIER Independent SpeedFusion is carrier-independent and the products are certified for multiple carriers. By combining the coverage network of various mobile operators, the likelihood of running into a blind spot or network congestion is minimized. RELAXED With the help of WAN Smoothing, network traffic is assigned to the WAN connection with the lowest latency. Use multiple WAN connections to create a single, jitter-free data stream.
