Who we serve

Dokodemo Denwa is a small company focused on private 4G and 5G networks for operators outside the large national carriers, and for the enterprises that rely on them.

Internet service providers
ISPs adding fixed wireless or mobile service on private 4G and 5G, with voice and SMS on their own core.
Competitive local exchange carriers
CLECs building their own wireless layer alongside fiber, and offering voice and messaging over it.
Enterprises
Companies that need a private LTE or 5G network integrated with their fiber network and IT systems.

Our IMS is radio-agnostic and integrates with any RAN vendor, so it fits the equipment these operators already run.

Fiber and private LTE together

Many sites already have fiber but need wireless coverage across a campus, a yard or open country. We integrate private LTE and 5G with your fiber network: fiber backhaul to radio sites, core functions hosted on your own fiber infrastructure, routing into your LAN and IT systems, and voice that works across fixed and wireless lines.

Construction and implementation

Alongside our software, we offer construction services such as tower construction, macrocell and shelter installation and permitting, plus installation and support for core network platforms. See our services

Our mission

We build IMS software for private networks that combines the strengths of cellular technology with openness, performance, security and flexibility. Our solutions follow global standards such as the 3GPP specifications for LTE and 5G, so they interoperate today and stay ready for what comes next.

Virtualized and open
A fully virtualized IMS architecture that supports NFV and cloud-native deployment.
Performance
Low-latency communication with support for URLLC on 5G networks.
Easy to run
Straightforward management and integration through clear dashboards and APIs.
IT integration
Direct connection to enterprise IT, including SDN and orchestration tools.
Native voice
Built-in VoLTE, ViLTE and VoNR for high-definition voice and video.

Our IMS scales from small tactical networks to large enterprise deployments, supporting millions of devices while keeping carrier-grade reliability.

Built on field experience

Our founders have deployed IMS in demanding settings such as disaster response, industrial IoT and smart cities, delivering high-quality voice and video over open spectrum including CBRS. Our software is built on that experience.

Built for use around the world, the software supports a wide range of industries and use cases, integrates with existing infrastructure, and complies with international wireless standards.
