Verizon is upgrading the capabilities of its in-home network equipment, adding new custom-built routers made by Actiontec and Westell that will boost in-home speeds over coaxial cable to up to 175 Mbps from the current 75 Mbps, and allow operation of multiple simultaneous in-home Wi-Fi networks.

Some immediately will note that there is no need for that much speed when the access connection doesn't run that fast. True, but there will be more of a need to create in-home sub-networks, creating four 43 Mbps virtual wireless LANs in the house. That might be useful for walling off networks used by children in the house. It might be just as important as a way of creating secured home office networks and content sharing networks as well.

One way of ensuring quality operation of real-time networks is to create separate virtual LANs that do not have to contend with traffic generated by all other devices on the network, such as printers and PCs, for example. A voice or communications VLAN ensures better quality by giving the real-time traffic its own dedicated network.
