i have to make this project called "city bus information system".
on the display in the bus all the info regarding the next stop,last stop,exp in mins information is to displayed,and same can be done on the bus stop.
for this i need to make a radio link between the bus and the stop...wht link should i use...i want to use a radio link...any suitable frequency.
the bus stop will relay the information to the bus...and the display in the bus will display it.
any help regarding the circuit is also appreciated.
secondly i am planning to connect the bus stop to a central server..and i think a gsm/cdma link between the bus stop and the central relay station will be good.so the central server could be updated with all the info from all bus stops.through sms service.
all calculations done here(relay stn) it can send the required info back to the bus stop which relays to the bus.
the proj is still in nascent stage,so any other suggestions would be helpful.
