Symmetrical Up/Down Capabilities
In Full Duplex communication, the upstream and downstream traffic concurrently use the same spectrum , doubling the efficiency of spectrum use. Unlike FDD (Frequency Division Duplexing) where spectrum is split between the upstream and downstream (as in current DOCSIS networks), or TDD (Time Division Duplexing) where spectrum is time shared between upstream and downstream traffic, full duplex communication enables upstream and downstream traffic to efficiently use the same spectrum at the same time.
10x the Upload Speeds Available Today
Before today, maximum upload speeds of up to 1 Gbps were possible. Now, with full duplex technology, we’ve been able to significantly increase upload speed capabilities which will enable very high-capacity symmetrical services for residential and business services. Today, a typical broadband customer’s upstream data consumption is only 10% of their downstream consumption. As new technologies and applications emerge that enable customers and their devices to share interactive high-resolution video, our networks will be prepared to support the speed and latency requirements.
