Although the new infrastructure
can be implemented almost anywhere, the system is especially suited for
high-speed, multilane, divided highways in urban, high-traffic environments. By
exploiting a small cell architecture and the 60 GHz frequency spectrum, the new
network technology uses lightweight, low power, mobile units while maximizing
frequency reuse to provide extremely bandwidth-efficient wireless service. Advantages
of cordless and cellular systems are integrated by deploying very small
picocells along high traffic roadways. Although each of the picocells has a
radius on the order of 100 feet, the system can easily facilitate high
bandwidth communications to mobile units traveling at speeds up to and in
excess of 100 miles per hour (mph).
This is accomplished by
interposing moving base stations between mobile units traveling down the
roadway and fixed radio ports uniformly distributed along the median of the
roadway. The moving base stations allow communication links to be established
between the mobile units traveling on the roadway and a fixed communication
network through the fixed ports. The moving base stations adjust their speed and position to allow each moving base station to efficiently provide communication links to a group of mobile units traveling on the roadway. As can be seen in the infrastructure diagram, the number of mobile uni hand-offs in this proposed system is significantly reduced in comparison to conventional small cell systems since the moving cells provided by the moving base stations track the mobile units.
