Definitions

  • the present invention relates to wireless communications More particularly it relates to a system and method for both formation and configuration of a wireless network which may be portable and which is easily installed in a short time frame
  • the system yields major bandwidth improvement for permanent cellular communications installations and is highly portable.
  • it is also especially well suited for temporary installations such as disasters or emergencies where the cellular and radio systems for first responders are no longer functional
  • cellular wireless systems operated by telephone and wireless phone companies employ large towers or buildmg-mstalled cellular transceivers.
  • Such transceivers with the appropriate antennas are each permanently installed at specific points in the cellular system. These points are chosen carefully to maximize coverage in a small area of the cellular grid so as to maximize communications between phones and devices in that portion of the grid, and the transceiver in the tower
  • Each such tower operates on the FCC assigned wireless frequencies for telephones and mobile communications devices using transceivers to communicate between each tower mounted transceiver and the cellphones and radios and computers on the ground.
  • each cell tower in the grid is hard-wired to the land-based telephone and telecommunications system in its geographic area.
  • communications from users in the individual cells in the grid, to a respective cell tower, are communicated then to the hard-wired telecommunications system thereafter.

  • the system and method allow for the construction of a wireless communications grid in a matter of hours This far surpasses conventional cellular style grids which conventionally take weeks, or years to complete. As a consequence, initial deployment of a grid to provide cellular communications with users in a geographic area is less expensive even when employing the system with permanant towers for long term installations.
  • the system employing a plurality of individual towers in the grid, and only requiring one tower to have external land or satellite based communications connections, is also rendered highly adaptive If a hole in the grid becomes apparent, a new tower can simply be transported to fill the hole If a natural disaster or emergency occurs wiping out local communications systems, the system herein may be rapidly deployed by simply transporting one or a plurality of towers to the geographic point of the emergency, and turning the system on It may also be transported to locales where in emergency situations communications between emergency personnel are taxed due to fixed bandwidth of the installed local system or a broken local system.

  • a center interface tower may also be employed to insure the fewest hops of each communication, between towers, and on to the outside network
  • the backhaul channel may also be maintained in any frequency the antenna elements and transceivers will broadcast and receive, and in a plurality of individual transmission frequencies between the individual towers as needed

This determination will yield the shortest path through one or a plurality of individual towers in the grid, over the internal communications or back haul system of the network, to an interface tower, and transmit the communication in that fashion. Communications from the land-based or exterior systems, through the interface towers, to a user in a footprint of one tower will be handled in the opposite fashion.
  • the backhaul communications between the towers is constantly maximized for throughput to and from the interface towers by the system software constantly ascertaining the fastest path through the backhaul system for the communication to take to and from an interface tower.
  • the number of backhaul channels available may be adjusted by adding and subtracting transceivers and antenna elements to match need

Abstract

L’invention porte sur un dispositif et un procédé permettant de former et de faire fonctionner un réseau de communications sans fil à l'aide d'antennes montées sur une pluralité de pylônes pour former une grille de communications. Le réseau comporte un système de liaison sans fil entre les pylônes pour communiquer avec un pylône unique relié à un réseau, tel que le réseau Internet, ce qui évite d’avoir à relier par câble chaque pylône à un réseau. Les antennes de chaque pylône fonctionnent dans un certain mode de polarisation pour les communications des utilisateurs, et dans un second mode de polarisation sur des canaux individuels formant le système de liaison. Il est possible d'augmenter ou de diminuer le nombre d'antennes individuelles sur la liaison pour former un nombre plus ou moins grand de canaux pour les communications sur le système de liaison afin d’augmenter ou de diminuer l’aptitude à gérer le trafic de communications entre utilisateurs et avec les communications de réseau extérieur en fonction des besoins et en temps réel.
