Ali sa strane korisnika oprema je dosta skuplja, ADSL modem je mnogo jeftiniji i praktičniji od antena i ostale skalamerije koju treba negdje kačiti. Ali ko uopšte razmišlja o korisnicima. Plus to je ipak wireless pa makar bio i Wimax, tek kada se u praksi pokaže da to funkcioniše bez problema može se smatrati pouzdanim. Baš da vidim da će to funkcionisati bez optičke vidljivosti na 50 km. Znači Teol će imati 70 Mbit pakete, pa prešišaće Kosovo i Sloveniju po brzini. Mada piše da je na 10 km propusna moć realno 10 Mbit.
Možete zamisliti objašnjavanje sa tehničkom podrškom Teola ako nešto ne bude funcionisalo? Ja ne mogu. Za to će trebati debeli živci.
I dalje ne vidim neke značajnije prednosti ovog sistema u odnosu na ADSL, valjda ti iz Teola znaju šta rade.
Možda je ovo odgovor, mada se odnosi na zemlje koje nemaju dovoljno razvijenu žičanu infrastrukturu. Ako je potrebno mnogo ulaganja u telefonsku mrežu, onda ima smisla.
Citiraj:
Although the cost per user/point of WiMAX in a remote application will be higher, it is not limited to such applications, and may be an answer to reducing the cost of T1/E1 backhaul as well. Given the limited wired infrastructure in some developing countries, the costs to install a WiMAX station in conjunction with an existing cellular tower or even as a solitary hub are likely to be small in comparison to developing a wired solution. Areas of low population density and flat terrain are particularly suited to WiMAX and its range. For countries that have skipped wired infrastructure as a result of prohibitive costs and unsympathetic geography, WiMAX can enhance wireless infrastructure in an inexpensive, decentralized, deployment-friendly and effective manner.
Znači ipak nije savršena tehnologija:

Like most wireless systems, available bandwidth is shared between users in a given radio sector, so performance could deteriorate in the case of many active users in a single sector, especially if proper capacity planning has not been undertaken. In practice, many users will have a range of 2-, 4-, 6-, 8-, 10- or 12 Mbit/s services and additional radio cards will be added to the base station to increase the capacity as required.

Myth #14: 802.16 has range of "31 miles"
Reality:
-Q: What is the range of an 802.16 base station?
-A: What range do you want to service? And what spectrum do you have?
-Cells supporting mobile broadband in a metro area will be limited in practice, in most cases, to around a mile.
Toliko o tome da će pokriti cijeli grad sa dve bazne stanice.
