# Kumu Networks

> Kumu Networks, Inc. is a Sunnyvale, California semiconductor and RF technology company founded in 2011 to commercialize Stanford University research into full-duplex wireless and self-interference cancellation (SIC). It sells RF integrated circuits, cancellers (including the K8 canceller prototype) and self-interference-cancelling smart repeaters to wireless infrastructure, satellite, defense and aerospace manufacturers. Kumu Networks is a hardware/IP company, not an API platform: it publishes no developer portal, no API documentation, and no machine-readable API contract.

## Status

- No public API. As of 2026-08-04 no OpenAPI, Swagger, GraphQL, AsyncAPI, MCP server or A2A agent card could be found on any Kumu Networks host.
- The company web presence at https://kumunetworks.com/ returns HTTP 404 for every path from its WP Engine origin, and presents a wildcard `*.wpengine.com` certificate that does not match the host. The last successful Internet Archive capture of the homepage is 2024-08-10.
- Mail (Google Workspace MX) and an SPF record are still published for the domain; there is no DMARC record, no CAA record and no DNSSEC.

## Technology

- Self-interference cancellation (SIC / SLIC) allowing simultaneous transmit and receive on the same or an adjacent channel, roughly 200 MHz to 60 GHz.
- Applications: 4G/5G/6G network infrastructure, smart repeaters, Wi-Fi, IoT, satellite communications, and defense programs including US Army demonstrations and Department of Defense dynamic spectrum-sharing work.

## Artifacts in this profile

- [Domain security posture](security/kumu-networks-domain-security.yml): probed TLS, HSTS, DNSSEC, CAA, SPF and DMARC.
- [Well-known probe results](well-known/kumu-networks-well-known.yml): every `/.well-known/` and spec path probed, with observed HTTP status.
