I live in a suburb of Tirupathi (Not Tirumala Hills but Tirupathi city).In my suburb, a local company provides what they say 256 kbps unlimited for Rs.400. I contacted users of the service to find that even though speed does not match dataone's, it is twice faster than reliance rconnect and slightly slower than dataone!But they (the ISP) are not using any wires. They are also not using wifi because reach is large. They are also not using satellite because it is costly. They are also not using cordect because I contacted midas communications, the company behind cordect, and they said they have not heard of any such company!I am confused what technology they are using. I heard the representative say that the equipment that local ISP is placing costs more than Rs.10,000.Do you have any idea of what technology they are using?Are they using some fixed wireless technology used by sify?I dont know anything about fixed wireless technology of sify other than what I read in sify website that says that they use fixed wireless technology.they tell that equipment costs more than Rs.10,000.But security deposit is Just Rs.2500 and activation charge is Rs.1000.they connect through usb and they will have a rectangle/square shaped antennae in roof top.Please help1)Tell me more about sify's fixed wireless technology2)tell me what technology is that isp using
