My knowledge in electronics is limited. In general, the television remote use IR for sending signals. I would like to know if the same signals can be transmitted using bluetooth. If so are there any disadvantages in using bluetooth technology in television remote?

AFAIK yes. The TV remote signals do not require much bandwidth, so bluetooth might be overkill and not cost-effective if it's more expensive.

IR emitted by remote controls are too weak to have any harmful effect.but as i have read bluetooth makes use of weak radio waves,and its often thought that it may be harmful.many experiments have been conducted to determine its effects on animals.so i would say remote control which uses infrared is better.HOWEVER,bluetooth doesnt require a line of sight as infrared.

valid points!

 

I have a couple of doubts on blue tooth tech.

 

 

1. what would be the signal range that can be reached by various bluetooth versions (V2.0, V2.1, V3.0, V4.0)?

2. The signal range of my Bluetooth transceiver (class 1) is 100 m and of my device (say smartphone) is 10 m. Now with this transceiver, can my device send signals/ data which is more than 10 m away from transceiver?

 

If possible please provide me some links for the above queries

 

and Thnx for the reply guys

The PlayStation 3 DVD remote is a Bluetooth device. My biggest concern is the battery consumption. Traditional ir remotes are very efficient in comparison.
