CelModem

CelModem is a family of cellular modems intended to deliver wireless data connectivity over cellular networks to embedded devices, routers, and PCs. The design focuses on versatility, reliable operation in remote environments, and ease of integration. CelModem devices typically support multiple cellular technologies and bands, enabling operation across regions and network generations.

Key features:

- Multi-band 2G/3G/4G/5G support with optional eSIM or removable SIM

- Standard interfaces such as USB, Ethernet, and serial connections for broad compatibility

- AT command or API-based configuration for integration with hosts and software stacks

- Power management options including low-power modes and automatic reconnect

Security and reliability: Modems include encryption for data channels, firmware signing and secure updates, and options for VPN passthrough or IPsec. They can operate as standalone cellular gateways or as WAN failover in multi-WAN setups.

Applications: remote IoT and telemetry, point-of-sale terminals, fleet and asset tracking, remote offices, disaster recovery networking, and maritime or vehicle-based installations.

Development and ecosystem: CelModem modules are designed for easy integration with common operating systems, development boards, and software toolchains. They aim to meet regulator requirements across major markets and can be provisioned via cloud-enabled or SIM-based workflows.
