A network administrator needs to establish a dedicated outdoor point-to-point (PtP) wireless connection between two office buildings located 300 meters apart across an open campus. Which of the following implementation steps and equipment choices are appropriate for this specific wireless link? (Select TWO.)
- Mount directional antennas (such as parabolic dish or Yagi antennas) at both endpoints pointed directly at each otherAnswer
- Ensure an unobstructed physical line of sight and clear Fresnel zone between the two antenna positionsAnswer
- CUse standard omnidirectional antennas at both endpoints to broadcast signal equally in all 360-degree directions
- DConfigure the wireless bridge radios to operate on overlapping 2.4 GHz channels 2 and 3 simultaneously for bonded bandwidth
- EPlace unshielded indoor access points directly on the building exterior walls to lower installation costs
Answer
The two correct choices are to mount directional antennas aimed directly at each other and to ensure an unobstructed line of sight with a clear Fresnel zone between the two sites.
For a dedicated point-to-point outdoor connection between two fixed locations, directional antennas focus RF energy along a focused beam to maximize signal range and quality. Furthermore, keeping the Fresnel zone free of obstructions prevents signal diffraction and loss.
