Civil Work
The site installation process consists of the following five steps:
- foundation
- outdoor
- indoor
- grounding
- Activation
1- Foundation: At first TSSR is received. Thereafter a first observation is made according to the TSSR provided. Only then we can finalize the spot. After finalizing the spot the available map is implemented on the desired place. After a final observation the desired spot is completely flattened.The next step consists of excavating the site basement. After the excavation step the container and tower molding is performed and consequently concrete molding of the tower and container is done.After performing concrete molding, the excavation of the ground well and ground ring is preformed for grounding purposes. We could now install the container in the desired spot.In this stage the tower for later outdoor tasks is installed.
2- Outdoor: The first task after tower installation should be the installation of the antenna structure according to desired antenna heights and also installation of the antennas which is provided by the FSR. Once the structure is accomplished antennas could be installed on it. The next step is feeder cabling. Feeders are vertically fixed in place with feeder clamps all the way from the antennas to the tower basement. As the feeders reach the feeder ladder they are appropriately bent to fit into the feeder window. There is a ground busbar just 50cm above the ladder which could be attached to the tower. At this time feeders are connected to the ground busbar by the ground kit.After the accomplishment of all the above, tower grounding must be pursued. Tower grounding is aimed to connect the entire tower to the ground.
3- Indoor: After the foundation phase, tower installation and outdoor tasks there comes the time to be in charge of BTS installation works. Indoor may convey any sort of closed environment such as a container, room ,…. First of all BTS rack is put in place based on the preplan provided. Rectifier racks as well as batteries and DC/AC panels are also placed appropriately. After all necessary components are placed ladders should be installed according to the feeder window position in the room.N.B. Ladders must be placed far enough from the feeder window.Feeders as well as other cables will then lie on the ladders all the way to the BTS or any other component i.e. DC/AC panels.
4- Grounding: Grounding starts with excavation of the ground well. The second to be done is the digging of the ground ring which could be preceded by the insertion of a flat metal sheet deep into the well vertically placed to be in better contact with surroundings. A copper wire is the placed on the ring and the other end goes into the well to be welded to the metal sheet. For ground kits, a busbar to busbar cable is used. IGB, EGB and container basement are crossed together and the tower is also connected to ground. After making all necessary connections,, salt and powder are poured onto the metal sheet and all other wires which could then be buried in the ground. Finally the well is filled up with earth.
5- Activation: First to be done in this phase is to connect the HDSL modems. Two modems are used in this regard. One at the site place and the other is a remote one in the telecom toll office. These two modems should be synchronized together. They are connected via a 2Mb paired wire. The final step in site activation is called site offline.This phase consists of software manipulation of the BTS that depends on the TRX configuration. Different configurations are set via a computer and an appropriate link.
