Rivvor used OCP 2026 to publicly demo its Valen Edge Series Contactless Modular Compute System, a cable-free edge compute rack where server blades connect to each other over engineered mmWave wireless corridors rather than copper or optical cabling. The company framed the live demo as its first public demonstration of a wire-free rack using this approach for AI inference.
In the configuration shown, Valen ran as a three-blade system built with three AMD Ryzen blades, each with 128 GB of RAM. Blade-to-blade interconnect is handled by mmWave “wireless corridors,” with Rivvor listing 15 Gbps per link, seven links per blade, and 300+ Gbps of aggregate rack bandwidth. Rivvor also stated 250 ns of latency measured “application memory to application memory,” and said there are no cables or connectors between blades.
Rivvor tied the design to a straightforward data center packaging problem: inside dense AI systems, interconnect, power, and cooling all compete for space, and serviceability gets worse as cable counts rise. A wireless intra-rack fabric doesn’t remove the need for structured cabling elsewhere in a facility, but it could change how much physical routing volume an operator burns inside a chassis or rack, and how tightly network topology is coupled to the mechanical layout.
Rivvor said the system went from concept to working hardware in 11 months. The company also described latency work between earlier testing and the OCP demo, stating latency dropped from 1,600 ns round trip in an enclosed rack in June to 250 ns “application memory to application memory” at OCP, attributing the change to its low-latency baseband.
Beyond mmWave, Rivvor said it plans to move to sub-THz Bounded Electromagnetic Corridors (BEC) in the 100 to 500 GHz range on its own ASIC, targeting 400+ Gbps per link in higher-density systems. Rivvor also presented a poster titled “Cable-Free: Bounded Electromagnetic Corridors for Rack-Scale AI Systems” at the OCP Future Technologies Symposium.
“Cables were never built for how AI needs to scale,” said Nazym Paltachev, CEO and Co-Founder of Rivvor. “Eleven months from idea to a live wireless system. Now we take it into the field.”
