Internet Connection Through Bsnl Wll

My friend has a BSNL WLL(wireless land line) telephone connection in his home, now he wish to take net connection either Dial-uo or Dataone BB. Is it possible to provide internet connection through WLL ?? On query to BSNL people, they said OK it is possible. But I have some doubt. Will any one clarify ??
