Today i got bsnl wireless broadband (my friend had bsnl wired broadband and he was very unhappy with it so he got this wireless broadband and recomended it to me too )in which they put a small cpe on you roof and connect a wire into that cpe and then into your router. I have opted for 750rs plan that 6mbps unlimited no fup though i can change it to 10mbps upto 100gb then 2mbps unlimited for 745rs. Now i am curious that how does this wireless cpe technology works. How is it different from mobile internet or evdo or bsnl winmax and is it safe for home use. Like this cpe in your house near people or water storange tank on roof (as in my case they have tied it with piper connecting to my "pani ki tanki" so dosent this cpe emit harmfull waves.
