  1. thnx 4 the replies i already thought of using RF but the big problem comes when u have to identify more than one buses coming to the station u have to decide whether buses will transmit same frequencies or different ones and abt interfernce b/w signals ::) and if ure having multiple frequencies then receiver has to check all frequencies automatically . also once announced theres no need to announce the same bus again. now these r some of the problems which ive encountered with this project now wht should i do??? ::)
  2. hi, im doing an electronics&comm project as part of my curriculum. im thinking of an announcer system to be placed in bus stations which receives a particular code transmitted from a bus and announces to the passengers about its arrival. Is RF is a good choice 4 transmission ??RF has better coverage than IR doesnt it? also there r 2 ways i thought 4 code tranmission 1)DTMF signals - is simple but only few capabilities (no: of buses) :-\ 2)Digital transmission-of course more complex,also needing a uC but anyway im planning to implement it without a PC by using a uC :-\ so have any of u got anything that could help me out ??? bye!!
