Patent ID: 8588184

Claim:
A broadband data communications network comprising: a plurality of mobile wireless communications devices; a plurality of base stations configured for broadband data communications with said mobile wireless communications devices; a master access gateway configured to control broadband data communications between said base stations and said mobile wireless communications devices using a full data set; and a back-up gateway coupled to a given one of said base stations and configured to communicate with said master access gateway to generate a data subset from the full data set for said given base station and associated mobile wireless communications devices when communications between said given base station and said master access gateway is available, with the data subset being less than the full data set and comprising data for authenticating the associated mobile wireless communications devices as valid devices for broadband data communications with said given base station, and control broadband data communications between said given base station and the associated mobile wireless communications devices using the data subset when communications between said given base station and said master access gateway is unavailable based on measured signal qualities of the communications received from said master access gateway, with the control comprising authenticating the associated mobile wireless communications devices as valid devices based on the data subset for broadband data communications with said given base station.
