Claim 0:
1. An entry device for communicating external network signals between an in-home network and an external network, for communicating in-home network signals within the in-home network, and for preventing the in-home network signals from being communicated from the in-home network to the external network, the entry device comprising:
an entry port configured to communicate the external network signals with the external network;
a first network port configured to be coupled to a first interface of the in-home network;
a plurality of second network ports each configured to be coupled to a second interface of the in-home network;
a first splitter electrically connected to the entry port having a first leg and a second leg, wherein the first network port is electrically connected to the first leg;
an in-home network signal blocking device, wherein the in-home network signal blocking device is configured to permit the external network signals to pass therethrough depending on the external network signals being in a first frequency band, and to block the in-home network signals from passing therethrough depending on the in-home network signals being in a second frequency band that is different from the first frequency band;
a second splitter electrically connected to the second leg of the first splitter, and having a plurality of output legs each being electrically connected to respective second network ports of the plurality of second network ports, wherein the second splitter is configured to provide bidirectional communication of the in-home network signals among the plurality of second network ports;
a signal attenuation and communication device, wherein the signal attenuation and communication device is configured to:
permit the external network signals to communicate between the entry port and the first network port, and between the entry port and the second network ports, at least partially depending on the external network signals being in the first frequency band; and
block and permit communication of the in-home network signals between the first network port, the second network port, and the entry port at least partially depending on a direction in which the in-home network signals are travelling and at least partially depending on the in-home network signals being in the second frequency band and not in the first frequency band, such that the signal attenuation and communication device is configured to block at least some of the in-home network signals from reaching the entry port, and permit the in-home network signals to communicate between the first and second network ports; and
wherein the first frequency band is 5-1002 MHz, and wherein the second frequency band is 1125-1675 MHz.
