Two-tier wireless broadband access network

A method of providing wireless communication between a backbone communication network and a plurality of subscriber locations, the method comprising:

• establishing a first tier of a two-tier broadband wireless access network, the first tier including a first neighborhood access point configured to provide public access wireless communication and private access wireless communication within a first nanocell coverage area, wherein the public access wireless communication is provided when available throughput needs of subscribers having access to the private access wireless communication are met, and wherein the first nanocell coverage area has a radius less than or equal to one thousand feet;
• establishing a second tier of the two-tier broadband wireless access network, the second tier including a plurality of network concatenation devices, wherein each network concatenation device is configured to form an indoor network serving a communication device at a location associated with a corresponding subscriber;
• maintaining synchronization via a particular communication channel between the first neighborhood access point and a second neighborhood access point to enable shared use by the first neighborhood access point and the second neighborhood access point of a second communication channel, wherein the first nanocell coverage area is adjacent to a second nanocell coverage area associated with the second neighborhood access point;
• and
• providing private access wireless communication via the first neighborhood access point to a portable communication device associated with a particular network concatenation device when the portable communication device is within the nanocell coverage area and outside of an area serviced by the indoor network associated with the particular network concatenation device.
