CC2652R: Inquiry about Data Communication for use in an Implantable Device (under the Skin Surface of Human Body)

Part Number: CC2652R

Hi Team,

Hope you are doing good. I am reaching you in order to inquire about the availability of any component that can perform wireless data communication from an implantable device (inside a human body) to an external communicating device about 5-10 meters away (Tx-Rx gap). The protocol should be BLE and frequency should be 2.4 GHz. 

Other requirements are:

1. Can support location finding or direction finding 

2. Small enough to be used inside an implantable device

Currently, we have found CC2652R to be suitable for our application. This inquiry is to confirm whether CC2652R is able to fulfill our requirements. I would highly appreciate if you can comment or give suggestions because we are about to buy few components and development kits for it. 

Thanks

    Hi,

    CC2652R should manage to fulfill your requirements. If you go for CC2652RSIP with a chip antenna, you should manage to get a very compact design.
    CC2652R and CC2652RSIP are definitely capable to send Bluetooth 5.1 compliant localization packets.

    RF attenuation of the human body, especially in the 2.4 GHz band, can be pretty significant. Depending on the placement of the device, you may have fairly different attenuation numbers, so it might make sense to run tests to check this. You can also refer to the literature on this topic.

    I hope this will help,

    Best regards,

    Hi,

    Thank you for you response and detailed information. I really appreciate it. 

    I will consider your suggestions. Another thing I would like to ask is, whether CC2652R can be used for Beamforming applications? If yes, how many antennas will it require? For example, if I prepare a setup on a table with Tx system using CC2652R and another setup on another table couple of meters away (Rx system) using CC2652R. If I move the RX system at some angles to the Tx system, will the Tx system able to steer the beam of antennas towards the new location of Rx using CC2652R? 
    For beam forming, how many antennas can this Chip support?

    Thanks in advance for your suggestions

    Regards, 

    Ahson

    Hi Ashon,

    For Beamforming applications (also called AoA), you need a single antenna at the target, and several antenna at the locator.

    The CC2652R and CC2652RSIP can be used both as target and locator.

    I hope this will help.
