Design method for full coverage of digital trunking wireless intercom signals

Abstract

The invention discloses a design method for full coverage of digital trunking type wireless intercom signals, which comprises the following steps: determining the initial position and number of antennas according to the outline and area of ​​the target area; The intersection position of the antenna and the penetration loss of the obstacle that the antenna reaches the intersection position, obtain the indoor space field strength of the antenna reaching the intersection position; compare the indoor space field strength with the preset indoor space field strength and obtain the comparison result; according to the comparison Results Adjust the initial position of the antenna until the indoor space field strength is less than the preset indoor space field strength, and take the adjusted antenna position as the target position; if the outline of the target area is not covered by the signal of the antenna, increase the number of antennas , and determine the initial position of the antenna according to the contour and area of ​​the target area again. Solve the blind area formed by the shielding and absorption of the building itself in the large complex, and ensure the signal coverage of the entire indoor area.

Description

technical field [0001] The invention relates to the technical field of wireless intercom, in particular to a design method for full coverage of digital trunking wireless intercom signals. Background technique [0002] The role of information technology in people's production and life has become increasingly prominent. As an important way of information exchange, the wireless walkie-talkie coverage system has become an indispensable part of the management department as a wireless mobile communication tool in daily operation scheduling and security assurance. , With the development of the enterprise, it has also been continuously improved and upgraded to a more efficient, more comprehensive and more secure communication platform. [0003] The digital trunking wireless intercom signal coverage system is a new generation of communication platform, which makes the system upgrade and expansion more flexible, the voice is clearer, the signal coverage inside the building is more eve...

AI Technical Summary

Problems solved by technology

[0004] In recent years, due to construction reasons, especially large-scale complex buildings, the building structure is complex, and the reinforced concrete structure is more shielded, especially some underground buildings. The internal structure of the building is complex, and the blocking and blocking are different in different directions of the antenna, which will cause signal coverage. blind spot
