how to Boosting cell phone signal in the sales office building Underground park and lift

Background of the project: 
The requirement of Party A this time is to improve signal coverage in the office building display area. Signal coverage of the exhibition area: the first floor model house floor of unit 4 in plot 01, the marketing center on the semi-basement floor, and the parking lot on the basement floor (see the drawing for details).
These include but are not limited to:
1: Four sets of model houses on the first floor, elevator hall, office, VIP room, bathroom, viewing channel, etc.;
2: Semi-basement office, bathroom, live broadcast room, audio-visual room, elevator hall, etc.;
3: The parking lot and elevator hall on the first floor of the basement;
4: Four marketing elevators (four elevators stop at the basement floor, the semi-basement floor, and the first floor).

    mobile signal Coverage solutions:
The main device selected for this coverage is a 5W high-power tri-band host, which supports the FDD frequency band triple-network 2.3.4.5G network. This mobile signal coverage is divided into four parts sharing three sets of coverage equipment. The host device can be placed near the machine room of the weak electric well or the elevator well for easy wiring.

The first point: one floor + four marketing elevators and one host. A total of 20 points are distributed on the first floor area using mushroom head antennas to transmit signals. Elevator coverage Install a logarithmic antenna inside the elevator shaft. (Each elevator is equipped with a logarithmic transmitting antenna) In this way, the car can have a signal. The received signal is received by a large logarithmic antenna.

An installation example is shown in the figure below:

The second point: allocate a host in the semi-basement. A total of 12 points are distributed in the area using mushroom head antennas to transmit signals. The received signal is received by a large logarithmic antenna. An installation example is shown in the figure below:



The third point: a set of hosts is assigned to the parking lot and the elevator hall on the first floor of the basement. This area is relatively open and belongs to the channel-shaped area. Logarithmic transmission is used to cover signals, and there are 11 points in total. An installation example is shown in the figure below:
