1Gbit/s internet od UPC do jedneho roka


Recommended Posts

DOCSIS 3.0 24x8, to uz nejaky cas dava v Nemecku Unitymedia.. Intel Puma 7 odpad, ale to je odvaha nasadit 1 Gbit na DOCSIS 3.0 a obsadit 24 kanalov (to si nemecka Unitymedia nedovoli, tam je najvyssi program 400 Mbit a aj s nim su celkom problemy v spicke vo vytazenych oblastiach), upload je samozrejme rovnaky ako po starom (tym sa zjavne nechvalia, predpokladam, ze 30-50 Mbit). UPC PL asi uplne vypla analogove programy v kabli, kedze na 24 kanalov treba 192 MHz siroke pasmo (nemusi byt kontinualne), ktore zaberie jeden uzivatel sosajuci 1 Gbit (teda ak to vobec siet da a nebude to iba marketing).. a dychavicny Atom CPU v tom krame ma velke problemy pri vytazeni modemu 16 kanalov a viac.. uzivatelia sa maju na co tesit!

Edit: V specifikaciach ma sice ready to DOCSIS 3.1 (with firmware update), ale vieme, ako to chodi.. v kazdom pripade by bol DOCSIS 3.1 iba downlink (OFDM), upload je stale DOCSIS 3.0 (tak funguje sucasne nasadenie DOCSIS 3.1 u velkych US operatorov ako Comcast.. a ti po pruseroch s Intel Pumagate nasadzuju DOCSIS 3.1 modemy s Broadcom chipsetom).

Kolko tych kramov (connect boxy Intel Puma) musela Liberty Global nakupit, to sa s nimi budeme drb*kat este dalsich x rokov.. DOCSIS 3.1 tak skoro nebude (realne).

pozor 1gbit download ale len 40mbit upload, ziaden docsis 3.1, 1gbit je mozne objednat len vo Varsave v Polsku, avsak cena mi vysla viac nez dobra 99,99zl tj. 23eur je vyborna cena bez porovnania konkurencie v PL.

Otazka na UPC da sa poskytovat 1gbit pre siroku verejnost bez nutnosti technologie docsis 3.1?

Uz som to pisal.. da sa - ale musis mat siroke volne pasmo v kabli, co u nas (pokial sa nezrusi analogove vysielanie) nehrozi.. a jeden gigabitovy sosac vytazi cely uzol (24 kanalov.. tolko u nas ani nemame, UPC SK pouziva v sucasnosti 16 kanalov). Predpokladam, ze Poliaci maju DOCSIS 3.0.

Uplny DOCSIS 3.1 (vratane uploadu) nie je nasadeny komercne nikde na svete (napriek nadhernym powerpoint prezentaciam o full duplex ci 10 Gbit down/1 Gbit up.. v powerpointe vzdy vsetko funguje :-)))).. cize zatial je stale limit uploadu ako doteraz.

Comcast ide testovat OFDM upload (DOCSIS 3.1) teraz na jesen na obmedzenom mnozstve zakaznikov.. a to je iny operator ako nejaky UPC PL a s inym pristupom vyrobcov CMTS a koncovych zariadeni/modemov! V sucasnosti je kazda instalacia DOCSIS 3.1 hybridna - 3.1 down, 3.0 up.. a este to chvilu potrva, certifikacie CMTS a celej siete nie su za par tyzdnov..
