INTRODUCTION

On-the-job training (OJT) is one of the best training methods because it is planned, organized, and conducted at the employee's worksite. OJT will generally be the primary method used for broadening employee skills and increasing productivity. It is particularly appropriate for developing proficiency skills unique to an employee's job - especially jobs that are relatively easy to learn and require locally-owned equipment and facilities. This is one method by which students is given a chance to apply the theories and computations that they have learned from the school. It also helps the students to acquire relevant knowledge and skills by performing in actual work setting. Colleges and universities require their students to undergo such training within a specific number of hours as part of the curriculum.

Smart Communications, Inc., is the Philippines' leading wireless services provider with 47.7 million subscribers on its GSM network. It is a privilege to be part of their OJT program for a student like me to gain knowledge and skills in the field of telecommunications. Being hired as an intern on the company is such a big opportunity to learn a lot of informations about the said field.

First Week, March 30 – April 1, 2015

On the first day of my training, March 30,2015, it was started with a discussion. They discussed things that matters on the field operations. I noted the acronyms that are often used in the field like ATS, MTS, BTS and more. Each students were assigned to an Engineer who will be in charge for training us in the company. I was assigned to Engr. Ryan Carlo A. Asperas. It is important to familiarize the terms and acronyms being used to understand how a cellsite work. Site selfies is also introduced because it is important for getting datas that will be needed for completing database for each cellsite assigned to respective FO’s (Field operation Engineers). It is done with organize steps, and it is noted. After few discussions, we went to a site with my co-OJT students, with the Field Operator Engineer. It was somewhere in Porac with a site name Porac TP. We troubleshooted signals, and have checked the rectifier and the microwave facing the other site named Porac 9. The site was then down during that time. So, we replaced the rectifier and have repaired the microwave. After doing that, the site went back to stable status (up site).

The next day of the training went productive because we were on the field for repairing, testing, and troubleshooting signals for cellsites. I learned what the MTS main function and how it works to a site. Sometimes, not all important details are mentioned during discussions, then it is suggested to ask the engineers to gain knowledge for the questions that is formulated in our minds. There are times I hesitate to ask Engr. Asperas, but I tried to set aside those hesitations for the sake of learning. Since my two colleagues were not around, I was just the OJT student who went out with my FO. We went to Mexico for repairing a down site named Mexico 5. It was located far from the town which is in the middle of the field. The site was down because of outage due to high temperature. Engr. Asperas then tried to cool down the NPU3 instead of replacing it. After doing that, luckily it worked. The site went to a stable status again.

After two days like working, on the third day, I was just assigned to stay in the office for updating and inputting database from the datas that my FO gathered from his previous database. I was just there the whole day doing that.

Second Week, April 6 – April 11, 2015.

On Monday, we had another discussions about field operations, just additional informations to some important terms and acronyms about telecommunications. That was a very long discussion. It started in the morning, and resume after lunchbreak.

On Tuesday, we visited a site located at Mawaque, Mabalacat, a cellsite named MCT804. Datas that will be needed for inputting database were noted and captured by the camera we use for that matter. We checked ACU (Aircon) functions that is important on each container van maintaining the temperature of the equipments to avoid overheating inside the van. Once an ACU has defections, it should be reported immediately for replacement. We went also to Sta. Ana site for checking signal status. And lastly, we’ve been also to PLDT Dau cellsite for troubleshooting.On Wednesday, I was just in the office working for database regarding to the informations we gathered from the sites we visited previously. On Thursday, there was a discussion about GSM network how it functions. I’ve learned the importance of MTS, its role in the  system and how messages and calls is being sent to the subscribers.On Friday, we updated database in the office with my co-OJT students.On Saturday, we drived to SubicTel at  Subic Bay, Olongapo City for delivering some equipments needed by the FO’s working for mobile internet installations for some events. We delivered the needed equipments that will be used in the installation of MEOW, which means Multi Equipments On Ways. Below are just some examples of self selfies we were capturing on each sites:

The tower. It should be taken to determined its type and its height.

Third Week, April 13 – April 18, 2015.

On Monday, I just stayed in the office working for the database. I was given the task to finish Magalang, PLDT Mabalacat, and Angeles1 database. I inputted the datas we have gathered. On Tuesday, another office work was given to me. I completed another two sites for database. The next day, I worked for database again. Lately, I enjoyed working for databases. It enhanced my skills on using Microsoft Excel. On Thursday, Friday, and Saturday, we have finished 12 database sites out of 37 sites. We still have 25 more sites to finish as the due date is nearly approaching us.

Fourth Week, April 20 – April 25, 2015.

On the first day of my fourth week in the training, I am almost literate on using Microsoft Excel. That was another learning aside from working in the field. Another day of just staying in the office working for database. The next day, the field operator engineer who was assigned to me was not around. The other team, with other ojt students ask me to join them in their field work. Engr. Gomez, offered me to go with them on their site. We went to Porac for repairing the down site. The microwave of Porac site is facing another site located in Dila-Dila which are interconnected to each other. The FO didn’t see anything wrong  with the equipments in Porac site but then it was still down. He decided to drive in Dila-Dila for checking the signal status there. It is found out that this site is also down. And the rectifier had something wrong, so it was fixed and repaired. After that, both sites went back to normal operation. Another day of working in the field with another field operator engineer whose Engr. Panlilio because my FO was still not around that day. To gain more knowledge outside I decided to go with the other team, and good thing two of the three members was absent that day, then I go. We visited Engr. Panlilio’s site at Mimosa located inside Clark. They gather datas about the equipments on that site. I help them determining the azimuth angle of the antenna and its tilting. That was another learning and knowledge. After the Mimosa site, we went to Porac site gathering datas. Again, I was assigned to get the azimuth angles of the antennas on the tower. I was taught the proper use of the compass they use for getting it. That was a very long day working under the burning heat of the sun. After that site, we went to the adjacent site of the Porac site that is located at Paralaya, Libutad, Porac. On Friday, I was just at the office working for database. Also, the next day, we were just in the office working for databases while our FO’s were busy doing their office works upstairs in their office.

Fifth Week, April 27 – April 30, 2015.

The week started with a site visit, and doing the PMR (Preventive Maintenance Report). We went to Mabalacat3 site with my FO, Engr. Asperas and my co-OJT student, Mark Den Allare. The site is located at Brgy. Tabun, Duquit, Mabalacat City. We had a site selfie for data gathering purpose. Afterwards, we visited Xevera Mabalacat site. We’ve encountered some troubles while on the site. I have checked and listed deficiencies on the site, and found out that one of rectifier modules is no good, so we had to replaced it for a new one. The next day, I just continue doing and completing database in the office of Smart Communications, Inc., at Dau, Mabalacat, Pampanga. And for the next two days, we had been doing this database for rushing deadlines as Engr. Selom ordered that it should be finish before May 15. Below is the illustration of the database that we were doing for weeks.

The week started with a site visit at Angeles 1, we’ve done doing the Preventive Maintenance Report (PMR), and had a troubleshooting. The site is noted as a down site due to fiber cut.We used OTDR known as Optical Time Domain Reflectometer for checking fiber optics length. I also checked the site’s deficiencies. The next day, it was a staying-day at the Smart Office in Dau to continues doing the database. To make this day productive, I paste the pictures on the Microsoft Excel that is needed for the SID. On Wednesday, the whole day was spent well in the office for the database  assignment. Again, we’ve done pasting those pictures taken in each sites for SID requirements. The pictures were organizely put into their labels that was written on the Microsoft Excel. On Thursday, It seems to be a very long day in our team. We just had 4 site destinations. First, we wewnt to Porac TP site that is located at Cangatba Porac for the link correction facing Porac 5. Then, we drive to Magalang-PAC for checking the signal status beacause it is founfd out that site as unstable. After Magalang-PAC, wwe went to Magalang TP site for the same activity as what we did in Magalang-PAC. Lastly, we went to Magalang14 for site selfies, and deficiency cheking. The next day was another a day well spent in the  office working for the database. The Supervisor Engineer called a meeting to finalized the plan for May. Those final and addition sites to our FO was given then. Our team have finalized the sites which are already completed, and also noted those are not yet finished. On the last day of the week, Saturday, from Dau Mabalacat we went to Talang Candaba for trtoubleshooting signal status of the site. After that we went to Camba Arayat for repairing the down site of the 3G. When everything became okay and done,we drive to Mexico Digitel site for site selfie, checking and listing deficiencies that will be needed for SID.

Seventh Week, May 11 – May 15, 2015.

It is the second to the last week of my training. On Monday, we just worked inside the office and continued compiling the database, and have tried to fix the errors in the database format. On Tuesday, We had site audit at Porac 9 and Porac 3. We’ve done doing a Preventive Maintenance Report in both sites, and we were able to get the antenna orientations of the panel antenna and microwave antenna.

 On Wednesday, We again had a site audit at Mexico Sabanilla. We gathered datas and done updating RSL (Receive Sinal Level). Also, I listed all the deficiencies that can be found on that site. On Thursday, We just stayed in the office, again, working for the database designations. Also, we helped the engineers in the office to their office works to lessen the work. On Friday, We had database update  and input the datas in Mexico Sabanilla site. Then we went to Marque 1 and 2 cellsite to assist  the ericsson contactor and have been able to observe RUS software update there, and added a second E1 on both sites.

Eighth Week, May 18 – May 22, 2015.
