Outdoor Wireless Bridging (PtP & PtMP): Deployment Architecture
Establishing long-distance point-to-point (PtP) and point-to-multipoint (PtMP) links requires strict adherence to physical radio frequency (RF) physics. Optical line-of-sight (LOS) is necessary but insufficient; engineers must calculate the First Fresnel Zone radius using:
At least 60% of the first Fresnel zone must remain free of topological obstructions, trees, and buildings to prevent destructive multipath phase cancellation.
