Why is there no signal even when the shop is located in the busy area of the city?
Businesses can't get phone calls, consumer complaints, and store business is worse!
But Lintratek can cover a full cell signal in just 4 simple steps:
① Details of Project
|
The store signal coverage in Sichuan , China |
|
| Project Location | Chengdu Sichuan , China |
| Coverage Lengths | 150 square meters |
| Project Type | Commercial Use |
| Project Brief | The signal is blocked by the tall building,there is a signal outside the front,but the signal inside the shop is very weak. |
| Customer Demand | Enhanced triple Netcom function |
② Design scheme
The store is located in Chengdu, Sichuan Province, an old commercial street, surrounded by tall buildings, the store is located in the ground floor of the building group. The owner divided the shop into two floors, with the lower floor being used for business and the upper floor as a resting area.
The shopkeeper said: there is a signal outside the facade, but the signal inside the shop is very weak, and there is no service in the attic, and sometimes I miss a lot of important calls when I rest in the attic.
First of all, we must know that the mobile phone signal is actually an electromagnetic wave, which is emitted by the base station, and all electromagnetic waves can only propagate in a straight line, but when encountering obstacles or uneven media, diffraction or refraction will occur. In this case, the signal has been blocked by the surrounding tall buildings, and the transmission into the shop is already weak, and then into the attic is almost absent.
③ Product scheme
The shopkeeper wants to enhance the call function of the triple network (that is, the 2G signal), and wants to be more cost-effective. According to the needs of customers, the Lintratek signal coverage team recommended the KW17L-CD host, with a complete coverage scheme such as logarithmic antenna and ceiling antenna.
This KW17L-CD host supports mobile, telecommunications, Unicom 2G-4G network, aluminum alloy body casting, can accelerate heat dissipation, radiation partition, weathering and dust in one, and there are intelligent AGC chip, mobile phone signal is more stable, suitable for small and medium-sized self-built houses, shops, basements and other coverage scenarios.

④ How to install？
1．Install the receiving antenna:
The logarithmic antenna is installed in the outdoor area with a good signal source, and can be installed in the higher area at the door;
2．Install the covering antenna：
Because the ceiling antenna signal is downward divergence, so installed in the attic ceiling.
3．Connect the repeater：
Connect the feeders of the indoor and outdoor antennas to the host, and then power on.
4．Signal detection：
After installation, the "CellularZ" software is used again to detect the signal value, the RSRP value before coverage is -124dBm, after coverage is -83dBm, the coverage effect is very obvious!
(RSRP is the standard value for measuring whether the signal is smooth, generally speaking, it is very smooth above -80dBm, and there is basically no network below -110dBm)
