• Question 49:

  The following is the correct statement about the requirements for confirming the on-site environmental information during the WLAN site survey process?

  A. Confirm whether the site is completely consistent with the architectural drawings, and highlight the inconsistent areas, try to take photo records, and mark them in the drawings.Room number on site
  B. Take photos of the scene as thoroughly as possible in the room, especially the installation location of the equipment, the overall coverage area, the internal building structure, and new obstacles.Focus on the outdoor coverage, only need to focus on the obstacles between the AP and the coverage area.
  C. In the indoor survey, the obstacle type is distinguished from the drawings, and the actual position and material of each type of obstacle are marked. Different obstacles are used differently.Color marking and testing its 2.4G and 5G attenuation values
  D. During indoor survey, pay attention to other obstacles that are not drawn but affect the covering effect, such as load-bearing columns and artificially added partitions during decoration.Large objects such as broken and suspended ceilings
  E. Outdoors need to pay attention to the height and shielding range of obstacles on the site. For irregular obstacles (such as trees), try to take photo records.

• Question 50:

  What is wrong with the WoC scheme in the following options?

  A. The WLAN and CATV signals are mixed by the signal combiner and input to the existing CATV cable, and transmitted to the CATV coaxial shielded cable. In the room, finally separate the signals through the splitter panel to achieve indoor wireless network coverage and TV signal transmission.
  B. The overall construction of WoC does not need to be changed too much, the construction impact is negligible, and the wireless coverage is better. It is excellent in wireless system transformation projects Obvious
  C. Signal combiner and WoC panel, need to be customized separately from the partner
  D. At present, the cable commonly used by CATV is SY(W) V75-5 coaxial cable, which is specially produced for cable TV. The transmission frequency of 2.4G is very small, so the distance from AP to terminal panel can be longer, but it is recommended not to exceed 500 meters
