Wireless walkie-talkie signal coverage system

This design is designed according to the full range of indoor and outdoor coverage of the building. Specifically, it includes: the upper floors of the building, the air defense layer, the outdoor park and the beach area; covering public areas, guest room floors, elevator halls, stairwells, machine rooms, etc. If necessary , our company will organize personnel to carry instruments to carry out field tests of this project to ensure that there are no blind spots in the coverage area.

Combined with the digital intercom communication system, a new generation of digital intelligent patrol dispatching management system is tailored for property security users. The new generation of patrol system combines wireless communication technology with the traditional patrol system to realize digital intercom and patrol Great combination of two into one. wifi jammer, The patrol information is sent back to the patrol dispatching station in real time through the short data transmission function of the digital intercom system, so as to truly realize the real-time online monitoring of the patrol personnel. At the same time, the digital voice provides users with more Clear sound quality more effectively guarantees dispatching and commanding.

(1) Adopt the digital wireless intercom system base station inter-frequency transfer technology to expand the communication range of the intercom

When the communication between the walkie-talkies cannot be realized due to the long distance or the obstruction of buildings, the base station can transfer the signals of the walkie-talkies in different frequencies, and then send the signals through the distribution system, thereby expanding the communication distance between the walkie-talkies;

(2) The underground parking garage of the building is equipped with a distribution system to solve the problem of signal shielding in the basement. The distribution system consists of an indoor omnidirectional antenna, a flat-panel directional antenna, a coupling distributor, a power distributor, a trunk amplifier, a connector, a low-loss radio frequency cable, and a leakage cable. gsm jammer, Combined with national electromagnetic radiation standards and building structure, antennas are distributed in every corner of the basement, and then connected to the center of the base station through cables, so that wireless signals can be received or transmitted through the antenna, so as to reach the entire basement area of the building The wireless signal coverage; the outdoor area of the building adopts a low-power outdoor omnidirectional antenna, and the output power is adjusted through calculation to ensure that the entire outdoor area of the building is covered, and at the same time there will be no signal leakage out of the peripheral area of the building.

(3) Shared system to increase communication capacity

The shared system is composed of a combiner, a splitter and a signal tandem controller, which can integrate up to eight digital base station signals into the same distribution system for reception or transmission, saving materials, repeated wiring, debugging and other unnecessary investment, thereby reducing costs;

(5) Wireless intercom patrol system

Under this system, real-time patrol management can be realized by adding patrol dispatch management center, patrol software, information button, and patrol walkie-talkie.

Combined with the actual communication application requirements of the building, a variety of wireless communication coverage schemes in the building have been formulated. The following principles are adopted for the construction of the scheme:

1. Sex principle:

The system as a whole must have a certain level from resource allocation (including hardware equipment, technical means) to functional use.

2. Reliability principle:

The reliability of various resources of the system, including hardware equipment, etc. must have a certain high standard, work stably, and be easy to maintain; in the event of a hardware failure, there must be a reliable backup means.

3. The principle of technological maturity:

The system should adopt mature technology as far as possible, so that it can be put into practical use after completion and achieve the designed use effect.

4. Scalability principle:

The overall structure of the system is reasonable, the design capacity is moderate, and it must be scalable. On the premise of protecting the original investment, resource expansion can be increased, including the increase of communication coverage and distance.
