No uplna idyla by bola - ethernetovy kabel, 2 pary - RX a TX, na jednom prijmac a na druhom vysielac. Rychlost - 100 mbit, full duplex. krasa... mozne problemy: timeout na dorazenie packetu v ramci "kabloveho" segmentu na optike, citlivost prijmaca (pracuje sa na vysokej frekvencii) a vysielaca, dosah (bolo by dobre ak by to slo do 10 km (to som ale optimista, co?Smile)
ak by take nieco niekto vedel spachat....

mno ono ani 10 mbit full duplex by nebolo na zahodenie, ale myslim ze dnes uz nie je problem zohnat 100kovu ethernetku a vrazit do routera Smile)
ak by niekto vedel take spachat za 20K (a v principe by to stacilo aj na 10 Mbit FD) a vedelo by to chodit na troska vacsie vzdialenosti (do 9 km mi staci:-)) tak to budem povazovat za velmi dobre riesenie a zoberiem od neho takychto spojov nie male mnozstvo (jasne ze nie naraz ale postupne, ako budu financne zdroje:-))
a tahat ethernet aj z druheho poschodia je v pohode, aj nad parkoviskom je v pohode, problem moze byt ale v tom, ze na to 6te poschodie to pojde asi pod blbym uhlom a bude sa to uz flakat niekomu pred oknom - tomuto to moze vadit Smile)

Wink optika na 9km sa musi asi brutalne dobre nastavovat;))) xe
komercne riesenia nie su ?? bo pred 2 rokmi som listoval a nasiel rychlosti 155-600 mbps... boli rozne modely,, len cenu neslo nikde zistit;)))

panelak a tahanie kabliku ze parkovisko: no s tym mavanim kabla,, mas pravdu,,, a vietor si tadial statne fuka; este ja mam takych super rodicov,, ked som im povedal ze spravim 1 dieru pod okno,,, na drzia,, ma skoro dorazili;)

mno komercne riesenia mozno su, ale otazne je za kolko penazi ? ak by som mal tych penazi vela, tak sa nebudem kaslat v neakom verejnom 2.4 GHz pasme ale si kupim licencovane pasmo a zariadenia nan (hlavne tie zariadenia su svinsky drahe, lebo nie su vyrabane v takych seriach) a nemusim mat problemy s ftakmi prelietajucimi cez opticky luc, alebo si rovno necham zahrabat opticku trasu do zeme Smile) Takze otazka znie, ci je nieco pouzitelne na dlhe vzdialenosti sa rozumne ceny (9 km, cena radove max 20 - 40 tis.)
a kabel je lepsie tahat zo strechy ako z okna, ani anteny naokne nie su bohvie co (najma ked ti v nich v zime huci vietor Smile) a ked ich tam budes mat viac a cele okno obrastene ze ani von nedovidis Smile

komercne riesenia su, ale radovo od 500.000, pricom za rovnake peniaze urobite aj wireless trasu nad 10gb na platenom pasme, takze je to jedno.

Preco sa zatial neda urobit 100MB optopojitko do 20K? 100MB ma uz taku hustotu signalikov, ze laicky povedane ledka uz ma problemy zhasat a zapinat sa, je preto nutne pouzit specialne s rychlonabehom, ale tie nestoja 5 korun. tiez je problem s nastavenim optiky, a to uz na 1km nieto na 10 km.

laser je rychlejsi, ma vsak vacsie problemy v dazdi a hmle.

Sam som si optopojitko na baze ronje doma robil, takze som rad, ze to chodi na 500m a po upravach bude chodit na 1km a ked sa to da na plosak (CRUSAIDER), tak to bude uplna pecka.

To ze sa to zatial neda spravit do 20K je mi jasne, je nutne totis spravit dokopy 4 kusy (na kazdej strane 1 TX,1 RX), co pri snahe o kvalitne prevedenie skratka nejde.

Osobne by som vlastnorucnu ronju (powered by ClOCKRONJA) pod 30K nepredal Smile, ak vobec Smile

pokial by to dalo hoc tych 10mbit/s ale dokazalo by to ist na 9km spolahlivo, tak by mi to stacilo...
