post ni yg i dok cari sejak petang tadi .. i dah nampak ari tu tapi time bz .. camne bleh tak nampak tadi pun tatau ..
EMW ka ?
EMW memang very mathematics ..
tapi actually nak ikut senang je (assuming u buat B.Sc lah .. )
basically kena tau main ngan maxwell equation pas tu kena reti fix boundry limit
(camne nak cakap dlm english pun i tatau .. ) kat boundry tu kena maintain continuity current/voltage (tu hukum physics lah) .. then propagation equation ..
pas tu jgn sesat dlm berjuta juta equation yg nak kena develop dah laa .. dan of course jgn silap dlm develop benda tu .. lain jadinya ..
i rasa tu lah yg paling penting.. i pun dah dekat 5+ thn tak bermain ngan EMW nih ..
unless EMW II tu dah masuk guna material anisotrop (camne nak eja dlm english i maleh nak cari) ..then memang leceh laa .. kena guna tensor dll .. |

akum..apepon tq banyak2 ape2 tips yg SR bagi tuh..hmm insya allah
try la sedaya mgkn ape yg bley time kasih ma..
actually next month start sem baru so harap2 nih la kali terkahir aku repeat paper nih hehehe..doakan la ye hehehe tapi rase kali nih takde masalah lagi ma
aku dah insaf tobat dah lepas nih tetiap kali kuliah aku nak dok first row
tunjuk muka skema + budak baik serta lain2 lagi yg bley bodek kasi cair skit hati lecturer tuh hehehehe,,ini saje lah senjata terakhir terpaksa hamba lancar kan

adeh lebai mail ...
Wireless ni vast laa .. nak cakap pasal R&D dia lagi laa vast ..
ikut gak level mana ... part mana ...
antara target utama = increase capacity .. reduce power .. cut cost ..
ikut doktrin cheaper faster better smaller longer simpler ..
semuanya berkait ..
utk research yg directly concern korang dan product yg korang familiar : handphone
ada research estetik .. macam kaler screen makin cantk (lagi screen cantik/besar, lagi consume power .. lagi cepat bateri abis, lagi banyak memory yg perlu .. nak effect display . lagi complicate program dlm hp, lagi banyak memory lagi mahal cost.. bla bla bla), research supaya boleh tukar skin (bukannye mudah nak buat tu at the begining .. nak kena redesign semua supaya hp tu tak mudah sangat rosak biler org ganaz nak cuba tukar skin, secure dari sebarang masalah elektrik, kiranya kena ade minimum protection biler handphone tu "bogel" masa tukar kulit .. kalau senang rosak hp tu tak laku plak .. dll)
ada research security/reliability .. contohnya handphone jatuh dari meja tak pecah .. masuk dlm air tak meletup and better hp tak rosak ..
ada research look and feel/ergonomic .. u pegang hp tu rasa best (rasa best bergantung pada harga actually walauipun kos dia hampir sama) .. so ade research pasal material dan cat dia .. ada research allergic kat material/cat baru .. even ade research utk tengok samada cat/plastk handphone tu tak lusuh sbb tangan berpeluh .. ataupun dlm environment pelik macam berpasir, bergaram, dll ..
even bunyi flip/slide hp tu pun kekadang ade research supaya dengar macam mahal/murah (fisiologi/psikologi research.. ).. software tu simple abis .. utk high end kekadang sengaja dicomplicatekan sket supaya org rasa berbaloi dgn harga dia ..
research mekanik lagi .. yakni plastik yg surround handphone tu utk kasi rigidity and at the same time, susah utk org biasa bukak tapi senang utk org maintenance buat repairation (berkait dgn di atas)
tu baru research yg takde kaitan dengan handphone .. utk keluarkan satu handphone baru .. rasanya ade 150++ engineer R&D yg involve in the making model tu (dan variant dia lah .. banyak reuse gak actually).. tu tak kira engineer testing/production dll
so mail .. kalau u nak tahu apa yg hot di r&d kan .. u kena tahu part mana yg u nak tahu .. idak citer selama 1001 malam pun tak abis
salam thethethehhhhehehe:lol
ada doktrin noo..cheaper faster better smaller longer simpler ..
bukan faster better smaller longer simpler, expensive ka?:lol
aku nak tau part increase capacity and faster...
laa ni capacity berapa banyak?
berapa laju?
ni kat partmana nih...receiver? tranceiver?
tq..... |

tender?
laa ni ada project wireless school....nanti aku nak masuk tender aku contact hang...wokeyyy??:lol
sarah, hang ada involved ka dgn wireless school project nih?
kalau ada sure pakai merc mata pepatung punya nihh..:hug: |

oo increase capacity ka ?
lani dok kecoh ngan transmitter space diversity (multiple antenna).. space time, space frequency, space code, space time frequency, space code time, space code frequency space code time frequency .. coupled ngan receiver diversiy..
tu research panas skarang (ade kena mengena ngan research i gak .. ouuppss )
unless capacity yg u maksudkan tu tak sama ngan capacity i .. 
increase capacity, rate increase gak (faster lah)..
yg expensive tu bila jual .. cheaper bila buat .. hehe .. ikut persepsi sapa laa mail .. nak increase profit margin lah senang citer..
umts (3G) targetnya 2Mbps ... (kalau memory i masih elok) ..
4G of course naik lagi ..
kalau u tanya apsal WiFi bleh naik sampai 54Mbps (dan lebih lagi ..) tapi umts baru 2Mbps .. jawapannya range dia lain, environment dia lain, power dia lain dll ... |

hmm..semua berkaitan dgn space...space tuh space nih space nun, space ruang setan jer tak dak...
haaa..research hang tu laa yg aku nak tanya dari dulu lagi...
hang buat device ka atau apa ka?

akum..huauaha rancak nampak abg kakak kat sini citer wireless
heheheh btul cakap hang tuh macma langit ngan bumi tuh...
tapi tunggu haa kite kat sini tetap masih bawah satu perguruan
or jurus2 seni bunga yg sama aku tau aku masih junior so
kpd rakan2 senior perguruan izinkan hamba utk menuntut same jurus2
nih kalu ader tempang sana sinii tulonglah hamba membetulkan langkah yg sumbang tuh hehe..takpo2 tunggu kehadiran aku dlm dunia wireless nih..
i never giveup waluppon dah faile 5x maa..aku masih tak ketemu rentak
tok guru ku masih xhadir aura yg ada pada tok guru ku
tunggu nanti aku dapat serap aura2 nye nanti aku leh
join hagpa semua aku x paham pebende yg hangpa borak an kat atas nun

sarah,
bulhe citer sikit pasai pasai macamana nak convert dari optical signal ke electrical signal.. dari optical ke eletrical... |

pakai PIN utk O2E, LED/Laser utk E2O
ps: sorry zmn bz giler .. june baru settle |
