2.5G
=> Banyak negara yang guna
=> Lebih laju darii 2G tapi tak selaju dan tak secanggih 3G.
=> Contoh dia GPRS.

3G ...


tambahan .. EDGE yg digi guna termasuk dalam 2.5G.. sekian

2G
=> Tak boleh transfer data. Just boleh gunakan untuk hantar suara.
=> SMS pun termasuk dalam 2G.
=> Contoh lain, CDMA (Malaysia penah guna tech ni tapi kureng la).


Penerangan yang tak betul......salah ni

kalau dibuat bentuk lakaran, mungkin senang sikit nak paham kot. Andaikan permulaan ayat tu lingkaran paling luar berbanding ayat yang seterusnya...begitulah sampai ke lingkaran paling dalam (core network) menerusi ayat terakhir.

setahu kitelah yg jahil ni, ngn ni secara prinsipnya masih kabur lagi, kalau tanye pada ericsson, cisco atau ape je...masing-masing punya perspective yg berbeza tetapi asasnya sama...iaitu packet b ...


actually..ngn dan 3G tu berbeza.

heheh apa yang zexus nak cakap adalah actually macam sekarang untuk membawa sesatu service pada pengunna..( i.e data, voice,voice over ip,multimedia,broadcast, internet etc) memerlukan transport (transmission etc) yang berbeza...transport dependent. Kalau dlm Network Communication Protocol...actuall services sekarang memerlukan transport layer yang berbeza. Tapi dgn migrate ke NGN...transport layer akan sama...telco hanya main dekat service layer...semuanyo enable via gatekeeper. Data, voice,voice over ip,multimedia,broadcast, internet etc akan di pump ker gatekeeper terus ke pengunna. Sebab apa boleh camtu? sebab moving to NGN mean moving toward packet-based network.

contoh

Kalau Live telecast i.e TV...sekarang memerlukan 34mbs capacity utk di bawak dari KL ker Langkawi (ccontoh)..tapi dgn NGN..hanya perlu pump kan service tu ke NGN node.

betul lah tu ..

ngn kat core network .. user tak perlu tahu pun ade ngn ke ultraman ke kat isp/telco .. dia guna je apa yg dia nak ... and dia takleh nak cakap kat telco (TM contohnya),, wei TM, aku nak guna NGN .. boleh ke ?

3g plak is access network .. kalau user nak guna 3G .. boleh saja .. gi beli handheld yg 3G enabled ... peh tu .. gi tempat yang ada coverage 3G (celcom contohnye ... ) .. dan buat lah call atau surf lah internet atau tgk la TV kat handheld tu ... silap hari bulan.. semua data lalu ikut NGN TM masa kat core network .. ahaks ... .. eh TM ade ke NGN ?

tambah sket...

EDGE = 2.75G = 184kbps jeee (aku penah guna as a dial-up)

3G = up to 384kbps... kadang2 lebih... ni tgh guna ni... CELCOM 3G Unlimited...cmmg laju... sering dpt 50kBps utk download...
apapun teknologi nie masih baru dah mahal di malaysia... cth... Line Celcom 3G Unlimited yg aku guna skrg... rm150 sebulan... lanyak laa cukup2... jadi mangsa hp... pasal dijadikan dial-up modem

EDGE almost 3G.. sikit aje lagi. macam body perdana enjin waja.. heheheh atau advence GPRS
EDGE application operates dalm GPRS.. a lowcost 3G. mcm air asia instead of MAS yang sah ada kekurangan dlm satu dua perkara yang agak lag oleh sebab lower bandwidth. keupayaan 3G boleh dicapai tapi.. kureng dari segi kualiti dan totally different setup
