Low cost, short range (9m), low speed (300bps) wireless

Specification of the wireless communication:

• Range: Very short, 9m max.

• Can support 2 differences channels minimum (prefer 4+ channels). The purpose of more than 2 channels is for 2 set of transmitters and receivers can operate next to each others.

• Speed: Digital data rate is 300bps minimum, prefer 100bps.

• Power supply: 12V, [url removed, login to view], 3V (batteries powered).

What I need are:

• Schematics for a discrete or IC solution, one for transmitter, one for receiver.

• BOM with vendor sources.

• Total BOM cost for 5,000 quantities should be around $1 for both transmitter and receiver.

• Review my PCB for this design.

What I will do for this project:

• I will purchase the components. Components will be purchase worldwide, just give me the part number and names of the vendor.

• PCB layout: I will take care for the PCB layout (you will need to review my PCB layout).

What do you have to do if you want your bid to be considered?

• Estimate total BOM cost of your solution.

• If you want, you can tell me the total of discrete components and their value (R, C, L), and I can estimate.

• Winner bidder will be the one with lowest BOM cost.

• I will not consider any solution without estimate BOM cost.
