Abstract

An improvement in the design and deployment of collocated radio transceivers for high-speed wireless Internet access accomplished by increased isolation brought about by wrapping each transceiver in a shield of mild steel, enclosing collocated transceivers and associated equipment in non-reflective enclosures, use of low loss RF coaxial cables, and use of high isolation parabolic horn antennas.

Claims

1. An improvement in the design and deployment of collocated radio transceivers and associated equipment for high-speed wireless Internet access comprising;

shield wraps;

said shield wraps individually enclosing each of at least two radio transceivers;

said shield wraps being stackable one on top another such that said enclosed and stacked radio transceivers become collocated radio transceivers;

a non-reflective enclosure;

said non-reflective enclosure surrounding said collocated radio transceivers and associated equipment;

low loss RF coaxial cables;

said low loss RF coaxial cables being used to electrically connect said collocated radio transceivers to a source of information such that information can be transferred from said source to said collocated radio transceivers and from said collocated radio transceivers to said source;

high isolation parabolic horn antennas;

said high isolation parabolic horn antennas being generally cone shaped;

said high isolation parabolic horn antennas being solid reflector on all sides except the front;

said high isolation parabolic horn antennas having radiation patterns wider in the horizontal angle than in the vertical angle;

said high isolation parabolic horn antennas having rear reflecting portions in the shape of a true parabola with probes located at the focal point of the parabola; and

,

said high isolation parabolic horn antennas being electrically connected by said low loss RF cables to said collocated radio transceivers such that information transferred from said collocated radio transceivers can be transmitted from said high isolation parabolic horn antennas and information captured by said high isolation parabolic horn antennas can be transferred to said collocated radio transceivers.

2. The improvement in the design and deployment of collocated radio transceivers and equipment for high-speed wireless Internet access of claim 1 further comprising:

said shield wrap being constructed of mild steel.

3. The improvement in the design and deployment of collocated radio transceivers and equipment for high-speed wireless Internet access of claim 1 further comprising:

said non-reflecting enclosure being made of fiberglass.

4. The improvement in the design and deployment of collocated radio transceivers and equipment for high-speed wireless Internet access of claim 1 further comprising:

said high isolation parabolic horn antennas being constructed of mild steel.

5. The improvement in the design and deployment of collocated radio transceivers and equipment for high-speed wireless Internet access of claim 1 further comprising:

said high isolation parabolic horn antennas having adjustable vertical sides allowing for adjustment of horizontal beam width.
