4000 meters Tibet Plateau tunnel signal is too poor! Tunnel workers communication is inconvenient, affecting the progress of construction. What can we do? Enhanced call + Internet signals, Lintratek Signal Booster only used two optical fiber signal boosters to solve the problem of weak signal in the tunnel. The effect is far more than expected, and the workers frequently praise .
Project Detail
| Plateau tunnel signal coverage | |
| Project Location | Qamdo City, Xizang Province , China |
| Covering Distance | 1km |
| Project Type | Commercial |
| Project profile | The customer is located at 4000 meters plateau, the nearby sparsely populated, poor mobile phone signal, workers in this construction is very inconvenient. |
| Customer Requirement | Enhance the 2G-4G networks of the two major operators |
The customer is building a tunnel in the Tibetan Plateau, and the construction personnel can not make and receive calls normally because of sparse population and poor mobile phone signal near the tunnel. He hopes to do signal enhancement coverage in the two major tunnel, covering the mobile phone signal within a kilometer distance from the tunnel, and enhancing the 2G-4G network of the two major operators.
Design Scheme
After communication with the customer, the Lintratek Engineer confirmed that the equipment adopts two sets of 5W dual-frequency GD analog optical fiber signal repeater booster, respectively installing the near end of the optical fiber signal boosters at the two holes, installing the remote repeater about 500 meters away from the hole, and installing two large plate antennas from the remote repeater through feeder connections, one along the left and right sides of the transverse hole, and transmitting signals to both sides of the transverse hole.
Android users can download “CellularZ” to detect signal values，”BAND” refers to the mobile phone signal frequency band, involving communication knowledge, you can consult professionals; “RSRP” is the standard value to measure whether the signal is smooth, the unit of the signal is dBm, the range is -50dBm to -130dBm, the smaller the absolute value, the stronger the signal. Pre-installation test data showed that there was almost no signal for both mobile and telecommunications.For iphones, you can contact us to ask how to test.
After the signal detection, it proved that there was almost no local signal.
Product Scheme
This kind of 4g lte network extender is a high-power engineering chassis and supports customization of the following frequency bands. According to the signal detection (need professional help detection), the coverage area CDMA, GSM, DSC band signal is strong, these three bands support the customer needs of the two major operators 2G-4G network, Internet calls are smooth.
Field Installation
1. Remote Signal repeater and Near End Signal Repeater installation:
Installed the near end of the optical fiber repeater at the hole, and install the far end of the optical fiber signal repeater about 500 meters away from the hole.
2. Installation of transmitting antenna:
Two large plate antennas are installed from the remote machine through feeder connections, one along the left and right sides of the transverse hole, and signals are transmitted to both sides of the transverse hole.
3. Start the power supply after the receiving and transmitting antennas are connected to the host; otherwise, the host will be damaged.
4. Signal detection
After installation, you can directly detect the signal online, or you can use the “CellularZ” software to detect the effect.
The customer thought that in the 4000 meters uninhabited plateau, at most enhance the 2G call network, but after the guidance of the Lin Chuang team installation, now the call is no problem, the Internet is also very smooth, thank you very much for the patient guidance of the engineer, from the order to the solution is very fast.
