The invention relates to opportunistic wireless mesh networks which operate under random networking conditions. Such random network conditions typically limit the effectiveness of prior art wireless mesh networks, and more particularly to those supporting low power devices within the wireless network. Random network conditions include: random power supply, random node distribution, random node mobility, high mobility of nodes, random wireless link fluctuations, and random application traffic. The opportunistic wireless mesh network utilizes a two-layer architecture Embedded Wireless Interconnect (EWI) framework, which is adopted as the architecture reference model. A mesh network according to the invention supports opportunistically determining both mesh interconnections and network transmission routes by providing nodes with broadcast modules and unicast modules. The methods provide novel low power opportunistic wireless mesh networks that support interconnection with existing network infrastructures such as Open System Interconnect (OSI) based wired or wireless networks. Network embodiments provide protocol translation at network borders to allow micro- and macro-mobility management for wireless devices and their associated users. Additionally embodiments of the opportunistic wireless mesh networks address reduction in power consumption.

A method for determining the location of partition walls within a building uses a wirelessly interconnected network of nodes to determine relative spatial positions of selected nodes using (i) received signal strength indication (RSSI) values and time of flight (ToF) values, both indicative of a distance of separation between two communicating nodes. A first map of the network topology is derived from the RSSI values and a second map of the network topology is derived from the ToF values. The RSSI values are affected by building partition walls whereas the ToF values are relatively unaffected by partition walls. A comparison of the first and second maps is used to determine the location of partition walls within the building.

Periodic near field directors (PNFD) are coupled to a transmitter and a receiver for a short-range millimeter wave wireless (M2W2) interconnect for transmitting and receiving radio frequency (RF) signals at millimeter-wave frequencies for short-range communication with high data rate capability between the transmitter and receiver. Each of the periodic near field directors is comprised of one or more periodic coupling structures (PSCs), wherein the periodic coupling structures are comprised of metallic strips positioned such that their lengthwise dimension is substantially perpendicular to a propagation direction of the radio frequency signals between the transmitter and receiver. Each of the periodic coupling structures is positioned parallel to adjacent periodic coupling structures with a separation distance between each periodic coupling structure being within one wavelength of the radio frequency signal. The periodic near field directors may include first and second periodic near field directors that are coupled to each other for transmitting and receiving the radio frequency signals between the first and second periodic near field directors, wherein there is an air gap between the first and second periodic near field directors.
