• Excessive cable length
• A powered signal amplifier on the network that restricts the passage of frequencies in the MoCA
spectrum
Ultimately, any condition that increases line attenuation will decrease the reach and performance of
MoCA.
7.7.6 About multiple MoCA versions on a single network
MoCA 2.0 provides backwards compatibility with MoCA 1.1, such that a MoCA 2.0-compliant node can
operate at MoCA 1.1. Furthermore, if a network has both 2.0-compliant and 1.1-compliant nodes, the
2.0-compliant nodes can use 2.0 to communicate with each other, while using 1.1 for the other nodes.
The following notes are applicable to this supported scenario:
• Because of the time-division nature of MoCA transmissions, only a single node transmits at any given
time. Therefore, at any given instant, only a single MoCA protocol is actively in use, which facilitates
the use of multiple versions on a single network.
• If a 2.0 node is transmitting to a another 2.0 node, it uses the 2.0 channel bandwidth of 100 MHz,
along with any other 2.0 characteristics. Otherwise, the 1.1 bandwidth of 50 MHz is used.
• The NC must be a 2.0 node to allow any 2.0 communications. Otherwise, all nodes must use 1.1 at
all times.
