Coordinated antenna array and multinode synchronization for integer cycle and impulse modulation systems
An improved antenna arrangement and synchronization system for use when multiple radio base stations, using a deterministic over the air MAC layer, are located within overlapping coverage areas is disclosed and more specifically the method described here discloses an improved antenna and coordination arrangement for use at the base station which will eliminate over the air collisions while doubling the effective data rate of each base station. The result being large area networks which all share exactly the same radio spectrum without mutual interference and with little effort required to expand a single base station system into a grid of cooperative base stations forming a coverage area of ubiquitous coverage and multiplied data capacity.
1 . A coordinated antenna array and multi-node synchronization system for radio frequency transmission and reception comprising;
an antenna array having four antennas with each of said antennas having a radiation pattern of 90 degrees and horizontally aligned in a circular pattern such that said antenna array is capable of constantly transmitting or receiving in a full 360 degree horizontal pattern; and,
a base station radio operating four independent radio signals over the same frequency spectrum having four antenna outlets with one of each of said antenna outlets electrically connected to one of each of said antennas and with each of said antenna outlets time coordinated such that each antenna of said antenna array is receiving and transmitting one of the four independent radio frequency signals over the same radio frequencies at the same time.
2 . The coordinated antenna array and multi-node synchronization system for radio frequency transmission and reception further comprising;
said base station radio operating four independent radio signals over the same frequency spectrum having four antenna outlets with one of each of said antenna outlets electrically connected to one of each of said antennas and with each of said antenna outlets time coordinated such that each antenna of said antenna array is receiving and transmitting one of four independent radio frequency signals over the same radio frequencies at the same time but also only transmitting and receiving fifty percent of the total available transmit or receive time;
said base station having a medium access control system with a superframe structure containing timing marks to control timeslots of radio frequency receptions and transmissions; and,
one or more additional antenna arrays having similar antenna and base station configurations to said antenna array and wherein each additional antenna array upon power up detects the radio frequency transmission of said antenna array or one of said additional antenna arrays that is transmitting to identify said superframe containing said timing marks and selects the opposite fifty percent of the total available transmit or receive time not being used by the already transmitting antenna array to transmit or receive.
