AFAIK
beda penggunaan frekuensi aja bro..
untuk masalah kecepatan UL/DL itu tergantung Bandwidth yang digunakan..
misal ne kalo pake modulasi sinyal yang sama trus BW sama maka kecepatan UL/DL di tempat yang sama akan identik..
misal BW masing2 pada frek kerja 450, 900, 1800 adalah 5 MHz --> 450 (445-450), 900 (900-905), dan 1800 (1795-1800)..
nah, makin tinggi frekwensi kerja makin tinggi daya yang digunakan, makin gede gangguan (interferensi) yang dihasilkan...

berarti frekuensi yg rendah disini hitungannya lebih bagus ya bro?
(lebih hemat daya, lebih sedikit interference)

saya mau test EVDO soalnya utk rumah di Semarang.
tapi masih bingung mau pake Smart Jump atau Quick Net.

Re: QUICK net, pemain EVDO yg baru? - 01-12-2009, 08:50

secara teori yang saya tau seperti itu bro..
tapi itu hanya dari bagian transmisi saja.. dan sudah banyak mungkin teknik2 khusus untuk mengatasi hal tersebut..
kalo overall liat juga kapasitas core networknya, trafik yang ada, posisi kita dari infrastruktur (BTS) dan lain-lain...

Frekuensi QUICKnet yg lebih rendah (hanya 450 MHz dibanding yg laen di 800 MHz atau 1900MHz) membuat jangkauan/cakupan tiap BTS-nya lebih luas.
Jadi lebih efisien dari segi biaya infrastruktur operator.

Utk Smart ke depannya perkembangan jaringan kliatannya akan lebih cepat drpd QuickNet & juga ketersediaan peralatan/modemnya lebih banyak (banyak modem yg support dual band 800 MHz & 1900 MHz) shg sementara ini kliatannya lebih OK pilih Smart.
Tetapi kalo pake QUICKnet enaknya pemake masih jarang jadi kalo sinyalnya bagus mustinya speednya juga bagus.

masih kurang yakin sama Sampoerna... temen saya di Salatiga, ada yg pake Ceria modem 1x pake hape paketan dia, sinyalnya bagus tapi browsingnya susah

Lagipula, bukannya Ceria (sampoerna) fokus di pedesaan dan pedalaman? Agak ragu kalo Sampoerna mau manuver nembus ke daerah-daerah perkotaan

berarti kalo yg tinggalnya di perkotaan mending pilihnya smart, sedangkan yang tinggal di daerah-2 pedesaan, pedalaman ampe pelosok-2 lebih enak pake quick net sampoerna gitu yah hehehe...

Makin tinggi frekuensi, memang makin susah menembus halangan (kelembaban, air, tembok, pohon, dsb). Tetapi makin tinggi frekuensi makin banyak data yg bisa dibawa, speed makin tinggi.
UHF + redaman lebih kecil, nya ga harus LOS ...

Kalau 400MHz, termasuk UHF, frekuensi ini juga banyak gangguannya ...
Ultra High Frequency (UHF) (300 MHz to 3 GHz)
70 centimetres (420 - 450 MHz)
33 centimetres (902 - 928 MHz)
23 centimeters (1.24 - 1.3 GHz)
13 centimeters (2.30 - 2.31 GHz and 2.39 - 2.45 GHz)

Di frekuensi ini ada komunikasi dng HT, televisi, wireless mic, dsb ..
