E400 Series
5G SA, SD-WAN, and security appliance for hybrid WAN enterprise sites
The Ericsson Cradlepoint E400 is a powerful 5G SA routing and security appliance built for hybrid WAN enterprise sites. It combines embedded 5G NR Rel-17 connectivity, Wi-Fi 7, SD-WAN, and advanced zero-trust security in a single device — delivering reliable, high-speed performance with network slicing, failover resilience, and easy LAN extension via switches and APs.
The Ericsson Cradlepoint E400 routing and security appliance is designed to connect fixed locations using the latest standards of Stand Alone 5G cellular, Wi-Fi 7, satellite, and wired links. The all-in-one form factor makes it easy to connect offices, branches, store, clinics and pop-up temporary locations to the internet and critical applications without the need for extra hardware or complicated configurations. The embedded 5G or LTE modem means that connectivity is always available from day one without waiting for a wired connection while the dual-SIM ensures continuous uptime for connectivity.
Ideal for Wireless WAN
For organizations moving to a wireless WAN, the E400 offers the ability to pair 5G or LTE with a wired link and use a cellular link as a failover connection, hybrid WAN or a primary connection. For an all-wireless WAN, the E400 offers 5G or LTE performance, which can support the throughput needs of a small- or medium-sized office with the ability to add a second cellular connection to increase available bandwidth and reliability. The cellular modem offers advanced 5G technology to operate with 5G Stand Alone networks, which permit Network Slicing, or the ability to lock into a logical overlay performance–optimized for a specific use case with dedicated bandwidth, and quality of service. The embedded eSIMs provides deployment flexibility, expanded carrier profile options, and allows carrier switching without changing physical SIMs. An Ericsson provided minimal data plan on the eSIM allows for zero touch Provisioning and activation of the E400 in the field without additional connectivity requirements.
SD-WAN, Security Integration, LAN Extension Options, and Private Cellular
The E400 router offers SD-WAN to make cellular, wired and satellite connections optimized so that critical applications are assigned priority and run as expected even in challenging situations. Ericsson SASE zero trust security enhances the organization’s security posture by minimizing the attack surface, limiting the blast radius, and preventing lateral movement. A single policy engine integrates policies for Secure Connect, SD-WAN, and Zero Trust Network Access for a truly unified visibility and management experience, providing simplicity and scalability.
If the LAN and Wi-Fi capacity of the E400 isn’t sufficient for the location needs, expand the available ports and Wi-Fi clients with LAN Switches and Wi-Fi Access Points to add more users, more IoT devices and more applications – without adding complexity. This full stack solution, including the SD-WAN and SASE, is easily managed by NetCloud.
Additionally, the E400 router can serve as the user equipment router for private cellular networks that provide reliable local area network connectivity where wireless LAN fails to meet the network needs due to large areas or excessive congestion.
