Day 17(Tuesday, 27 April)

So as I mentioned before, today NPID from HQ will make a visits here for meeting...there were about 20 high ranked staff(technical manager, senior technical etc.) from HQ...while staff from Eastern Region involved were RNO Head, Hj. Nizam, Head of Department, En. Mohd Ridzal and all Head of Unit including my supervisor, En Wan Norhisham...so today nothing much I can do plus En Zul went outstation(for 2 days) to Kuala Lipis for new site survey with En. Syed...

Day 18(Wednesday, 28 April)

again today nothing much I can do except updating this blog...

Day 19(Thursday, 29 April)

as I arrived at the office this morning I saw En. Zul had already back from outstation but since there were no more site in Kuantan or any near site so I think today no more site visit...so I guess today I just updating this blog and self read and research in the internet...actually its already 2 weeks I didn't submit my logbook to my supervisor since that 2 weeks almost everyday I went to sites so I have a lot of things to convert from physical experience into words...so today I went to see my supervisor and he asked a lot of questions and there were some things that I didn't notice when I was at sites and that make him a little disappointed but he said its okay but the one that loss was me so he gives me some advice and learn from the mistake...so after that I quickly search the internet for the things that I didn't know...along with that En. Zul came to see me so I asked him everything that I have been asked by En Wan Norhisham that I didn't know...he also shows me the site master...site master is the equipment to test the Distance to Fault(DTF) and Voltage Standing Wave Ratio(VSWR)...

 Anritsu S331D Site Master Cable and Antenna Analyzer

Day 20(Friday, 30 April)

next week I will be under Transmission unit...En Wan Norhisham was not the Head of Unit of Transmission anymore and the the new Head of Unit was En. Zaidi Ab Razab...before, he was the senior technical officer...so En Wan Norhisham asked me to change the Reporting to Head of Unit column in my industrial training schedule for Transmission unit and told me next week I must report to En. Zaidi...

Week 3(Mobile Access)

Day 11(Monday, 19 April)

NPID meeting...meeting agenda were as following...1)Status update on April target on air sites...2)Site Aquired(SAQ)...3)Plan on air for May target...4)CME Purchase Requisition(PR) status...the meeting start about 10.30am...all HOU were involved and other technical officer too...so the meeting room quite crowded...in the morning session they were focusing on CME PR status...there were 25 own build sites...7 on tower...6 on lampole...6 on building and 6 on monopole...they also discuss on site aquired on SBC(company assigned by MCMC) sites...the meeting continue in the afternoon and this time they were discussing about the status update for April on air target and planned for May on air sites...according to KPI for May there were 25 sites 3G sites all in Terengganu supposed to be on air but as told by the logistic, there were limited equipment(node B) which was only for 10 sites(9 indoor, 1 outdoor)...so from 25 sites they discussed which sites were ready for installation..

Day 12(Tuesday, 20 April)

I didn't notified by En. Zul that today we are going for site visits so I dressed formal, suddenly that morning  he asked me to follow him to KIA Bukit Ubi and Dungun for commissioning...in the morning we(En. Zul and I) went to KIA Bukit Ubi because last week there were no rectifier as requested but on the weekend they sent the rectifier but with no battery so today the battery was delivered...at the site, the modem, node B and DDF was already patch but the PCM and alarm wiring from node B to DDF was untidy so En. Zul told the contractor to fix it...

        SAFT Rectifier without battery                        Huawei RTN620 modem                         DDF(above), DF for alarm(below)

arround 11am we went for commissioning 2G site(site ID: Risdam)...location Terengganu(Dungun) around 110km from Kuantan...

                  Tower Structure                                                     Outside                                      BOC,DB,cable ladder(behind)

Before commissioning, we have to make a loop at the modem and contact switching technical officer in Semambu to make sure that the site was connected/linked to the switch/RNC...then we rearrange the cards(TRE(trans receive equipment), ANC(antenna network combiner), SUMA(station unit module advanced)) of the RBS(Alcatel Evolium A9100) according to sector(1,2,3) for easy maintenance and upgrading and make the wiring/connection look tidy...then connect the network interface Port 1(75 ohm) to modem(120 ohm)...this connection must be interconnected by Balun...then connect ABIS port 1 to the laptop(serial port) to access into the RBS system and setting the Q mark address so that switching in Semambu can remotely access to the RBS because all the settings will be uploaded from there into RBS(on site just connect and put address)...

            Rearrange the BTS cards according to sector                                        Huawei RTN620 Modem

           View inside of BOC                                         Commissioning in progress                        Generator set(GENSET)

on site, we just have to wait for switching finished upload all the data into RBS...here we can see the RBS LED indicator whether the uploading is complete...after uploading complete, we have to connect the alarm wiring(main failure, rectifier failure and door open) and test whether the alarm functioning or not...thats all for commissioning 2G, next we make a drive test for signal coverage and test call...

Day 13(Wednesday, 21 April)

yesterday En. Zul said that today we will go to site in Temerloh so I didn't bring my laptop suddenly En. Zul told me that its not today...I didn't know what to do in the morning...I just read over and over the Microwave Survey Report(MSR), Cell Design Data(CDD), and SDP...all the document was dated 2007...therefore today I went lunch a little bit early and bring my laptop in the afternoon...in the afternoon, En. Zul asked me to follow him to Celcom Semambu(RNC and mobile switching centre,MSC) to search for antenna bracket for Kg. Jembal sites because logistic didn't send any bracket to the site so currently the antenna is attach to the boom using cable tie...there I can see how they monitor the connection between the MSC and all the RBS in the Eastern Region...they can monitor how many people were using the line for each sector and alarm from any RBS if occured...

Day 14(Thursday,22 April)

so today the activity was 3G commissioning at KIA Bukit Ubi...as arrived there Alcatel contractor(Abg Khalid and Abg Zarul) was already there and try to ping from the site to RNC in Indera Mahkota but failed...FYI for 3G commissioning, the contractor from vendor(Alcatel) will do the commissioning different compare to 2G which Celcom technician can done it plus all the settings were given by the vendor and the settings/data have to be upload on site...for 3G the connection between node B and RNC is using IP Address...3G configuration used at this site is 8E1(8 x 2Mbps = 16Mbps) of data rate transfer...but for commissioning purpose they only connect 1E1 from node B to DDF...

                         Pinging to RNC(Indera Mahkota) in progress                               Modem already patched to DDF

since they cannot ping from here to RNC so there must be an interconnection problems...as usual first thing in troubleshooting was to check the physical interconnection...but then still cannot ping...so maybe the interconnection between node B and RNC...so they called staff in RNC to reset IMA(interconnection from transmission link/MW and RNC/switching) in Indera Mahkota...but still failed to ping...in the afternoon they still cannot ping to RNC...after resetting the IMA for second time, they succesfully ping to RNC...commissioning complete...they connect all 8E1 from node B to DDF and node B LED indicator signal green(ok)...

                          Me on site                                       Node B physical connection troubleshoot

Day 15(Friday,23 April)

In the morning today, there was a meeting to list down issues and action plan due to NPID HQ will be visiting NPID Eastern Region on 27 April and also meeting on status update for April on air target...1)KIA Bukit Ubi Port 8E1 failed...2)Kg. Teluk(3G) in Kelantan Port 7E1 failed...3)Indera Sempurna no problem(8E1 commissioned)...so in the afternoon, I joined En. Zul went to KIA Bukit Ubi for troubleshooting but first we make a drive test for coverage signal and speed test at Indera Sempurna...all the residential area of Indera Sempurna was covered with 3G...next is KIA Bukit Ubi...there will be also Alcatel contractor(Abg. Zarul)...we disconnect all 8 connection from node B at DDF and connect only port 8 but still failed(node B LED indicator-red)...so En. Zul contact technician at Bukit Pelindung to make a loop(just connect KIA Bukit Ubi and Bukit Pelindung)...the node B indicator was green...so thats mean between this site to Bukit Pelindung has no problem...therefore there must be a connection problem between Bukit Pelindung to RNC in Indera Mahkota...so we just connect back all 8 connection from node B at DDF...

Week 2(Mobile Access)

Day 6(Monday, 12 April)

Since every Monday morning there will be a morning talk and tazkirah so I decided to go to the office early...so this morning I didn't sleep after solat Subuh and get ready around 8am and didn't take any breakfast because there will always be a breakfast at the office for Monday morning...I drove my car about 8.10 without rushing but still manage to arrived at 8.20...at 8.30 I went downstairs to listen to the tazkirah and morning talk...but after that they said breakfast was not prepared yet so everybody went back to their places...just wait for about 15 minutes one of the staff said"jom mkn"...went downstairs again and found out the breakfast was nasi minyak...huhu quite hungry though...what a "rezeki"...I ate at Kak Lin's(Hj. Nizam Secretary) desk and have a  chit chat a little bit...bla..bla..bla...After breakfast I went back upstairs and I thought I want to continue blogging but after a few minutes Kak Fazrina (NPID secretary) came in along with projector and laptop so I asked there is a meeting? Meeting about what?...meeting about the progress of last week April Target for on air sites…as planned last week there will be 2 sites in Kuantan that I will go accompanied by En. Zul and a few site that pending for delivery equipment before, already approved for delivery but still got sites that still pending approval from MCMC and shared site with Maxis still pending approval from Maxis…so right now is about 2.30pm, there will be a meeting with Alcatel-Lucent(contractor) planned at 3 pm but mmm I don’t know, just wait and see…mmm the meeting will be about 3G(node B) equipment…also tomorrow will be a meeting with supplier, Huawei, I don’t know when maybe tomorrow morning and it will be about transmission link(microwave)…yeah it’s 10 am tomorrow morning(Kak Fazrina said)…it’s 5pm right now…just went back to the office after having a drink(after the meeting) with the Alcatel-Lucent contractor(diorg belanja), my supervisor and En Fauzan…just listen to their chit chat almost all about work so yeah surely I’m blurrrred…let's go back to the meeting…the agenda of the meeting was SSV status…SDP submission…equipment delivery and installation…TP submission…3G on air sites for April(5 sites),May(25 sites),June(35 sites),July(30 sites)…before went home I have to certified my logbook for the last week activities first...huhu easily done I thought he would complaint but he just said to separate the activities to morning and afternoon that's all...end of the day...

Day 7(Tuesday, 13 April)

same as yesterday I arrived at the office 8.20am...I think I have to keep my attendance this way or even more earlier...this morning I guess I just have to wait for the meeting with Huawei at 10am so for about 1 and half hour I will just googled and wiki for the technical term and anything necessary...sharp at 10am 2 Chinese guy from Huawei walk into the meeting room so does Kak Fazrina, En. Fauzan, En Zaidi. and my supervisor, En Wan Norhisham..this time the as I said yesterday the meeting was all about transmission link(microwave)...its an update for delivery and installation of microwave and modem for the on air site target for April plus other sites also...the meeting was up to lunch(about 1pm) but sharp at 1pm I went home for lunch and solat Zohor...when I'm back to the office around 2.10pm Huawei guy already packed their laptop and have a chit chat outside the meeting room with Celcom transmission technical officer(En Syed and En Asde) so I just walk bypass them into the meeting room...Kak Fazrina's and En Fauzan's laptop were still there but no one there...after some time both of them continue discussion about summary SIF approval from last week meeting...3G overall for Eastern Region as of 28 February 2010...suddenly they found that the overall record from HQ and their record were mismatch (HQ overall 407 sites but Region 405 sites)...so they give me a task to find any mistake or error in their record which suppose to be 404(done) + 3(WIP)...it took me about half and hour to find the error since I have to compare 400++ sites...finished the task, I went for solat Asar and sharp 5.30 I went home(earliest so far)...

Day 8(Wednesday, 14 April)

yesterday, En Zul told me that tomorrow(today) he will bring me to 2 3G sites(Indera Sempurna-lampole and KIA Bukit Ubi-Rooftop)...so today I wear T-shirt(tug in) with slack pants instead of formal dressing...around 10am we went to Indera Sempurna first...

 

                      Lamp pole                                                 Skylift                                          BTS outdoor cabin(BOC)

skylift and contractor already there but equipment not yet delivered as planned plus Maxis link(microwave) was attach to Celcom's antenna boom since there was only one boom for microwave(MW) at the very top of the lampole which also marked for Celcom...so En. Syed had to call Maxis to send their contractor to relocate their microwave...

 

                           En. Syed, En. Zul(On the phone),contractor           En. Zul(Mobile), Abg Asde(Tx), En. Syed(Tx)

Maxis MW on Celcom's antenna boom

a few minutes later Huawei contractor arrived with link equipments(2 feet microwave,Huawei RTN620 modem)...so to not wasting time Huawei contractor assemble the modem in the BTS outdoor cabin(BOC) and attach the MW to the boom on lampole...since there was no boom for Maxis MW, Celcom's contractor fix a new boom to the lampole...

                   Transmission link(MW) installation in progress        Contractor connecting modem to grounding board

                View from the back of BOC         Modem installation in progress            Modem complete installation

in the afternoon Maxis relocate their MW onto the new boom but got problem doing alignment...so En. Syed and Maxis contractor discuss to solve the problem and the solution was to swap the MW, Celcom's MW attach to new boom while Maxis on the exisitng one...

Maxis contractor detach their microwave from Celcom's antenna boom

around 4pm the equipments(Node B,antenna,jumper cable,feeder cable etc.) arrived from KL but found that some equipments were not delivered(PCM cable,node B power cable) and wrong jumper to feeder connector...

Kathrein Antenna: X Pol, 1710-2200MHz, 18dBi, 65 degree beam width, 2 degree elec. tilt

                                      Mismatch(wrong) jumper-connector                              Antenna bracket

 
so the contractor just do what they can which were connecting the jumper cable(7/16 inch) to antenna and wrap the connection with insulation tape(weatherproofed the connection),lift the node B(200++ kg) into BOC and stored the equipment on site since they can't attach the antenna to the boom because transmission's contractor was using the skylift...

lifting the node B into BOC

 

next stop was KIA Bukit Ubi, its around 7pm already so they decide just to stored the equipments there and continue assembled tomorrow...we already request for trolley in the Material Request(MR) Form to lift the node B(200++ kg) because KIA Bukit Ubi site was on building(2 storey shoplot) but there was no trolley therefore they(the logistic transporter) need extra man power(pay to the contractor to lift equipments)...9.30pm went home...

Day 9(Thursday, 15 April)

Since yesterday equipment still not assemble so today one more time visit to Indera Sempurna site...from what I was informed, Maxis and Celcom's transmission MW was completely attached and aligned at 11pm yesterday...and today as we arrived, the antenna already attach to the boom on the lamp pole but the jumper cable still not connected to the feeder cable since the connector was wrongly delivered...

so today they(the contractor) brought their own connector (extra connector from previous sites)...I watched and learned how they fix the connector to the feeder cable(7/8 inch) and here was the result...

in the afternoon, they already connected jumper cable from antenna to the feeder cable and fix the feeder cable onto cable ladder...

 Cable ladder attached to BOC

while they were fix the feeder cable, Huawei contractor was aligning and commissioning transmission link...one person at the MW while the other at the modem(in BOC)...the modem was connected to the laptop and all the reading and status of the transmission can be seen...this MW is transmitting(L.O.S.) to Sg. Soi tower(about 4.19 km) so it must be synchronized(the frequency range(15GHz) from low to high or high to low, the output power gain etc.)...at the MW the contractor used voltmeter(voltage) to match(tuning) the power gain  in dB(shown in the laptop) as set by provider

Day 10(Friday, 16 April)

Today make a summary from the site visit but actually didn't know what to write from morning till about afternoon...it's about time to went home already suddenly En. Wan Norhisham came in and asked me what did I do today and I said study the new term and equipments that I learned from the site visit...so he asked me to put this on the logbook...first about mobile - antenna type, feeder cable, connection on node B, Distance to fault (DTF) calculation, Voltage Standing Wave Ratio(VSWR), total gain...second is about transmission - Microwave survey report(MSR), the installation, testing and commissioning...for mobile he said to asked En. Zul while transmission En. Syed...so finally I have an idea what to write...
