Antenna switching technique for improved data throughput in communication networks

Details

Inventors: Reynolds, Jim;
Assignee: Trimble Navigation Limited (Sunnyvale, CA)
Primary Examiner: Eisenzopf; Reinhard J.
Assistant Examiner: Bhattacharya; Sam
Attorney, Agent or Firm: Tankhilevich; Boris G.

The r.f. power generating apparatus interacting with the communication network is disclosed. The apparatus comprises the dummy load and the computer operated antenna-dummy load switch. The computer operates the antenna-dummy load switch in such a way that the attack and decay phases associated with the data transmission from the r.f. power generating apparatus to the communication network are eliminated. A plurality of the r.f. apparatuses interacting with the same communication network on the same frequency wherein each of the apparatuses includes the antenna-dummy load switch is also disclosed.

DETAILED DESCRIPTION What is claimed is: 1.
An apparatus for improved data throughput in a communication network; said apparatus comprising: an antenna; a dummy load; a radio frequency receiving-transmitting circuit; a modem coupled to said receiving-transmitting circuit; a computer coupled to said modem; a time-determination system coupled to said computer; an antenna-dummy load switch operably coupled to said antenna, operably coupled to said receiving-transmitting system, and operably coupled to said dummy load; and a computer software means; wherein said computer software means determines if a polling message including a reporting schedule has been received by said apparatus from said communication network; and wherein said software means directs said computer to operate said antenna-dummy load switch according to said reporting schedule at times determined by said time-determination system; and wherein when said antenna-dummy load switch is connected to said dummy load said apparatus is disconnected from said communication network, and when said antenna-dummy load switch is connected to said antenna said apparatus is connected to said communication network.
2.
The apparatus of claim 1, wherein said time-determination system is selected from a class of satellite-based time-location determination systems consisting of a Global Positioning System Receiver and a Global Orbiting Navigational Satellite System Receiver.
3.
The apparatus of claim 1, wherein said time-determination system is selected from a class of ground-based time-location determination systems consisting of Loran, Tacan, Decca, Omega, JTIDS Relnav, PLRS, and VOR/DME Receiver.
4.
The apparatus of claim 1, wherein said receiving-transmitting circuit transmits at a frequency, f; and wherein said receiving-transmitting circuit receives at said frequency f.
5.
The apparatus of claim 1, wherein said receiving-transmitting circuit transmits at a frequency f1; and wherein said receiving-transmitting circuit receives at a different frequency f2
