Hi,
I have a pretty ambitious project in mind, and 13 years of Electronics Repair experience to assist. Unfortunately, I have no design experience
I want to be able to produce a large number of transmitters, each with a small range (say 5 metres radius), and a number of receivers (up to 100).
The transmitters are fixed at least 10 metres apart, thus not interfering with each other (Yes I know they will anyway, but I hope to randomise their transmission intervals so that the crosstalk will be minimal), and transmit a unique signal. The frequency should be common, though the data transmitted should not.
The receivers are carried around the area, and pass through the areas transmitted in.
So, the receiver should know the ID of the last transmitter it passed by.
On top of this, the receiving station needs to transmit a small amount of data back to a central point that collects all of the information. The range of this transmission is around 100 - 200 metres. The information transmitted will be ID, Location, and Status.
The required end result is a mapped out area, where on a PC screen you know the last location of each node as it moves around the sensor area.
The nodes will move at a maximum rate of 5 metres per second, but only in short bursts of up to 30 seconds.
All I have at this stage is the concept, and the idea that it will involve PIC's and some Holtek https://www.commlinx.com.au/Holtek_chips.htm and tx/rx chips similar to https://www.commlinx.com.au/RLP433A.htm
Is it feasible? I think so.
Any assistance in this regard is most welcome.
PS, I live in Australia, so the frequencies available from the above URL's are my best bet.
