Leveraging S-CDMA for cost efficient upstream capacity

Synchronous Code Division Multiple Access, or S-CDMA, is a technology that was added to the DOCSIS 2.0 specification, but up until now, it has not been critically needed or significantly deployed.

However, an explosion in home generated content, growth in business services and an extremely competitive environment is putting tremendous pressure on the cable upstream pipe.

These and other events and conditions are coming together that will create a Perfect Storm for needed upstream capacity ... and S-CDMA may just be the best near-term answer.

This paper discusses how S-CDMA provides an efficient means to increase HFC upstream capacity.

We start with a brief look at factors driving demand for upstream bandwidth and some bandwidth models to estimate how much upstream bandwidth we are going to need over the next 5-7 years.
