d) at the conclusion of a WiFi communication period, sending a Clear-to-Send (“CTS”) to WiFi devices on the WiFi network and configuring the shared network bridge resources for WiFi communications;
wherein the shared network bridge resources comprise at least one of a baseband processor, memory, the transceiver, a power amplifier and a low noise amplifier.
2. The network bridge of claim 1 , wherein checking the MAP to determine whether the MoCA NC has scheduled MoCA communications in an upcoming MAP cycle comprises parsing the MAP to determine a time period for scheduled MoCA communications.

b) in instances where the MAP indicates that the MoCA NC has scheduled MoCA communications in an upcoming MAP cycle, configuring the shared network bridge resources for MoCA communications;
c) in instances where the MAP indicates that the MoCA NC has not scheduled any MoCA communications in an upcoming MAP cycle, configuring the shared network bridge resources for WiFi communications; and
d) at the conclusion of a WiFi communication period, sending a Clear-to-Send (“CTS”) to WiFi devices on the WiFi network and configuring the shared network bridge resources for WiFi communications;

wherein the shared network bridge resources comprise at least one of a baseband processor, memory, a power amplifier and a low noise amplifier; and
wherein the shared network bridge resources are assigned to only the MoCA network or to only the WiFi network at any one time.
8. The method of claim 7 , wherein checking the MAP to determine whether the MoCA NC has scheduled MoCA communications in an upcoming MAP cycle comprises parsing the MAP to determine a time period for scheduled MoCA communications.
9. The method of claim 7 , further comprising, upon configuration of the shared network bridge resources for WiFi communications checking for the occurrence of WiFi communications and, if WiFi communications do not occur within a predetermined time period, sending a second CTS to the WiFi devices on the WiFi network and configuring the shared network bridge resources for WiFi communications.
10. The method of claim 9 , wherein the predetermined time period is chosen such that if WiFi communications are commenced, they can be completed before the next scheduled MAP.
11. The method of claim 7 , further comprising, when the shared network bridge resources are configured for WiFi communications, sending a CTS before each MAP and a selected RR to cease WiFi communications, and reconfiguring the shared network bridge resources for MoCA communications to allow communication of the MAPs and selected RRs among MoCA devices.
12. The method of claim 7 , further comprising, communicating with a second network bridge to coordinate WiFi communications by the bridges to avoid overlapping WiFi communications by the bridges.
13. A communication system, comprising:
