sa signal meter ko is FULL BAR ang GPRS.

kaya nag isip ako ng way para tumaas ang signal to WCDMA to HSDPA, lumabas ako ng bahay kasama ang laptop,
napansin ko na nagbago ang signal from GPRS to WCDMA,
kaya 100% sure ako na magiging HSDPA ang signal ko
kung mailalabas ko ang Globe Tattoo modem ko.

Lets Start na po.

Steps by steps procedure

-buksan natin ang Globe tattoo modem
look na lang sa mga attached image

ito na yung RF signal receiver ng globe tattoo.
all we need is to extend xa kasi nga nakadikit sa kit.

try to remove yung screw ng RF receiver.

nag ipit na lang ako ng extension wire sa screw kasi ayaw ko i mount yung wire sa modem kit baka masira dahil nga plastic lang ito.

pag naikabit nyo na yung extension wire, ibalik na natin sa dati ang tattoo kit
kayona bahal maghanap ng butas na lalabasan ng extension wire ha
wag nyo kalimutan ang mga screw na tinanggalnyo ha,
wag iwala dahil mahirap humanap non.

Oras na para masubukan kung uubra na.....

eto po ang picture after malagyan ng extension wire.



although di xa nag FULL BAR sa HSDPA signal,
kasi di ko naitaas ang pinagdikitan ko ng extension wire sa alluminum antenna ng tv,
pansin naman na from GPRS nag boost xa to HSDPA.

hehehehe

feedback na lang po kung umubra sa inyo.

Magandang araw mo mga kaSB ito po ang first major tutorial ko dito sa Symbianize kaya pagpasensyahan niyo na kung may konting flaws anyway open naman po ako sa mga questions and opinion niyo..

Let's start!!!

Malamang katulad ko marami din sa inyo ang namomroblema bout sa 3g signal dito sa ating bansa kaya ang goal ng project na ito eh imaximize yung available 3g signal especially dun sa mga remote areas. BTW taga Pampanga po ako at problema din dito samin yang 3g signal na yan. Tignan niyo na lang yung SS ko nung wala pang antenna yung modem ko.

Hirap kasing makapasok yung 3g signal sa loob ng bahay kaya nga nagresearch ako ng solusyon.
CANTENNA! familiar na siguro kayo dito kasi ginagamit itong signal booster ng WiFi devices kaya naisip if applicable ba sya sa 3g modem and EUREKA! after some researches napagalaman ko na pwede pala siyang gamitin din sa pagboost ng 3g signal. Let's start building the project na.

Ingredients:
Lata - kahit anong lata pwede basta perfectly round and smooth siya mga size ng malaking del monte pineapple juice can)
Coaxial cable - ito yung gamit sa antenna ng TV kayo na bahala kung gano kahaba basta abot hanggang bubong niyo
Steel pole - mas mataas mas maganda

Ito lang yung major na requirements para sa Cantenna sasabihin ko na lang sa inyo yung mga dinagdag ko mamaya. OK.

First of all paano ba naten icoconect yung coaxial cable sa usb modem naten? Salamat na lang sa mga mababait nating masters dito sa SB at sa tutz nila kung paano maglalagay ng wire sa usb modem naten. Bisitahin niyo na lang sila

For modem with crc9 connector http://www.symbianize.com/showthread.php?t=126490 courtesy of Sir_bullydog22
For modems w/o crc9 connector http://www.symbianize.com/showthread.php?t=157497 courtesy of Sir_diegobayo
For zte usb modems http://www.symbianize.com/showthread.php?t=200161 courtesy of Sir_anglelsv

Note: yung gitnang wire lang ng coaxial cable yung gagamitin naten tanggalin niyo na yung nakapalibot na wire

Ganito yung magiging resulta niya


Ngayon gawin na naten yung mismong Cantenna...

Note: importante tong computation kasi dito nagiging effective yung Cantenna kaya hindi pwedeng i-skip to..

Madali lang naman siya may online calculator naman punta kayo sa website na to para sa computations ng antenna may guide picture din siya para hindi kayo malito
http://www.changpuak.ch/electronics/cantenna.php

Gumawa din ako ng SS para mas maexplain ko sa inyo ng maayos

This image has been resized. Click this bar to view the full image. The original image is sized 847x434.

Input niyo lang yung diameter ng lata dun sa first box at yung frequency ng 3g 2100mHz dun sa fifth box tapos yung ibang values dun sa picture gamit na lang kayo ng calculator madali lang naman siya basic algebra lang po yan
Important values:
a.) Length nung wire na nakausli dun sa loob ng lata
b.) Distance nung wire mula sa back portion ng lata

Pag ok na yung values mo pwede na tayong magbutas sa lata. Pwede kahit pako lang ang gamitin basta dapat hindi masyadong mayuyupi yung lata.
Unang butasin yung pagpapasukan na wire as seen on the SS make sure na tamang tama yung distance nung butas mula dun sa base ng lata

Next yung dalawang butas naman dun natin ima-mount yung screws para mailagay natin yung Cantenna sa pole mismo.

Gumamit lang ako ng 2 small nuts and bolts tsaka yung pangpadlock sa pinto as seen on the picture..


Bale ganito yung resulta niya..


Pagkatapos ilalagay na natin yung lata sa pole mismo, paganahin niyo na lang po yung creativity at pagiging maparaan niyo wala naman specific na technique sa paglalagay ng antenna sa pole, pwedeng niyong itali, idikit kahit welding pwede rin basta hindi masisira yung form ng lata.

Ganito yung ginawa ko..


Next ilalagay na natin yung wire sa loob ng lata make sure na yung nakausli lang na wire sa loob ang babalatan natin. Dapat tama rin yung haba ng wire as shown dun sa computations naten kanina..

Dapat perfectly vertical din yung nakausling wire sa loob para effective.


Next idikit yung wire sa pole para hindi nagagalaw yung nakausling wire sa loob ng lata..


AND WE'RE DONE!!!

Last thing is yung pagposition ng antenna sa bubungan natin.
NOTE: INGAT LANG PO SA PAGAKYAT SA BUBONG AT MAGPATULONG KAYO SA MGA NAKATATANDA.
Dapat may alalay ka rin na nakaharap sa computer at nagsasabi kung magangda na yung signal.
Kung alam niyo yung location ng cellsite ng ISP niyo dun mo itutok yung cantenna. Kung hindi naman take your time para iadjust yung position ng Cantenna.



Note: Prevent niyo lang po yung ganitong scenario kasi mawawalan ng silbi yung antenna.

If ever na napapalibutan kayo ng matataas na gusali iadjust niyo na lang yung cantenna vertically at rotationally


And at last yung resulta ng pinaghirapan naten mula sa walang kabuhay-buhay na 3g nagboost yung signal ko sa ganito. Lumakas na yung reception gumanda pa yung quality ng signal also known as your RSSI as seen dun sa diagnostics ng dashboard.

Benefits:
a.) Mas stable yung connection ko kahit peak hours as seen dun sa dinodownload ko na torrent.
b.) Hindi na nagsisignal drop yung modem ko as a result of several interferance sa atmosphere naten.
c.) Sobrang satisfied na rin ako sa browsing hindi tulad date na facebook lang aabutin pa ng 5 mins para lang magload yung homepage.

Alternatives:
Pwede rin yung ganitong setup kung ayaw niyong buksan yung modem niyo.

Same principles lang siya ang mahalaga yung proper placing ng usb modem sa loob ng lata (yung computations na ginawa naten kanina)
Ganito siya nun kung sakali mang usb modem yung nakalagay.

Beta pa lang tong project na to wait niyo na lang yung mga modifications at updates ko..

TAPOS NA PO!!!

Sana nakatulong yung mumunti nating proyekto sa pagpapalakas ng signal niyo.
Feedback na lang po dun sa mga gagawa nito very willing akong sagutin yung mga tanong niyo.
P.S. Tuwing gabi lang po ako OL kasi may pasok ako sa school basta free to post your comments, suggestions, kahit violent reaction tatanggapin ko...
MABUHAY ANG SYMBIANIZE!!!
