CC2530: Frequency division multiplexing

Part Number: CC2530
Other Parts Discussed in Thread: Z-STACK

Hi, everyone

I have 15 CC2530 EM, i use one of them as a base station and the others as nodes to collect some data and send them to base station.

I don't use Z-stack, I would to use frequency division multiplexing to send data from the nodes to the base station in different channels ( frequencies )

so how i can do  frequency division multiplexing??

    Hi,

    If you have one Base Station (One Receiver), why do you want to use FDMA?
    If you have Multiple Transmitters and Receivers operating at the same time then you can use FDMA.
    If you want to identify the Node then allocate the Address to that Node and include that Address Field in the Data packet.
    You can use LBT/CSMA technic for your network with a single channel

    Thanks,

    yes, I will use Leach protocol there are 14 nodes will be divided to two cluster heades every head collect data from its nodes and then the two cluster head send these data to the base station.

    I want from each cluster head to receive data packet from its nodes at the same time by using( FDMA ), and then the two cluster head send its data packet to the base station at the same time also.

    Hi,

    Yes, it seems feasible to use FDMA.
    You can use different frequency/channel for each cluster and the base station has to switch in between the 2 channels (in TDMA) to receive the data from the Cluster head.
