graduation project

No Brain No Gainhi my name is alaa i study communication engineering im looking for help in my graduation project.my project about tracking device using bluetooth,my idea is to use too devices one on the person that we want to track and the other with me,i dont know where to start,i wana circuits for this informations.thanx.

your idea is to track the person..is it so?

yes,but we also can track childs animals.

You will first need to determine some objectives before hand, such as:

1. What is the range of detection
2. Maximum size of tracking device placed on object

A method of detection include triangulation. This will probably be the easiest method, but would only be effective if coupled with GPS.

Bluetooth might not be a good option to use because of its high frequency selection. Signal strength will easily fade, and there might be a lot of interference from existing 2.4 GHz WLAN deployment areas.

May I suggest the used of lower frequencies? Maybe under 100 MHz.. or pick a frequency that aligns with RFID ones, such as 13.56 MHz.

first thanx for your help,second i chose bluetooth because in my country we cant use GPS,and as you know its a graduation project so the range will not be big it will be like 50 meter,can you please explain the triangular method to me and about the other frequencies how can i use them??if you have any site that contain informayions or circuits that would be kind of you.
