- The reported result covers a 100-metre experimental link.
What changed
NTT announced an outdoor experiment carrying roughly 2 terabits per second over 100 metres in sub-terahertz spectrum. Its system combines multiple spatial channels with analog and digital processing, reaching up to 22 simultaneous channels. The company says this arrangement reduces the digital computation required compared with fully digital processing.
Why it matters
For network planners, the result suggests a possible future link where installing fiber is difficult. NTT identifies connections between buildings and mobile network equipment among potential applications. The useful advance is the combination of capacity and distance in an outdoor test.
What remains unproven
NTT still identifies prolonged operation and integration with existing systems as future work. The announcement establishes an experimental link, without demonstrating commercial availability, everyday reliability or the proposed future support for simultaneous connections to multiple locations.
