Vyyo Increasing Cable Capacity

Vyyo is offering products that increase the amount of spectrum that cable companies can use in the coaxial cable portion of their Hybrid Fiber Coax (HFC) networks by 860 MHz. I recently had interviews with the CEO and the CTO of Vyyo to understand the impact of its technology on cable networks competing with the new Telco IPTV networks.

Vyyo stated that if the new spectrum that it makes available is used for IP based services such as IPTV, video on demand, and DOCSIS 3.0 cable modem services, that cable companies can support four TVs simultaneously watching HD on demand content as well as support VoIP and DOCSIS 3.0 100 Mbps data services for groups of 50 to 100 homes.

The cable companies introduced HFC to groups of about 500 homes and several of them are decreasing the size of these groups down to about 100 homes. The Vyyo system does not require a significant decrease in the size of these groups to provide services that should be competitive with ATT's U-verse and Verizon's FiOS services in the U.S. It appears that Vyyo's products go further in making the cable companies competitive with Telco IPTV services than other technologies such as switched digital and coarse wave division multiplexing.
