    I'm a beginner in software radio and have two naive questions:

    1. What' is the radio front-ends? In the introduction table, I find USRP daughterboard, radio, and adapter. What' s the relationship among them?

    2. Need I purchase all of them?

    Actually, we intend to utilize Software  radio to build a RFID reader for protocol analysis. Can Sora help us? As we known, somebody has used USRP2 to build such system in MobiCom 2010. I am confused to make a choice between USRP2 and Sora. Could anyone give me some advices?

    1. The radio front ends are either the WARP Radio Board "daughter card" (http://www.mangocomm.com/products/boards/warp-radio-board-v1 ), or any of the USRP "daughterboards" listed in the section called Daughterboards for both USRP1 and USRP2 (http://www.ettus.com/order ). The "Radio" is the SORA hardware itself, called a RCB - radio control board. The adapter is simply what you also need based on if you're using the WARP system or the USRP system - you specify this when you are submitting the Academic Kit forms.


    2. It should be noted that part of the idea behind SORA is that all these daughterboards in some way or another could be used, since they all share an interface and SORA is supposed to be programmable to work in all these varying spectrums (See: differences between WiFi and LTE), but as of right now there is (at lease, last I knew) only firmware for the USRP XCVR 2450 and the WARP Radio 1.4.

    I can't really help more than that, hopefully someone else can.

    Hi Young,

    By design, all the USRP radios are supported by Sora with the USRP adapter. But currently, we have only implemented the firmware for XCVR 2450. A good news is that we are going to release the source code of firmware in USRP adapter next month (November 2010), coming together with Sora SDK v1.1. With the source you can make small modification to build firmware for other USRP radios.

    Young,

    The firmware of the connector board (not RCB itself) will be included in our next release.

    It will not be difficult to modify to support other daughter boards in USRP series.

    Thanks,

    - Kun

    Thanks for you kind reply. 

    I am not sure exactly understand your last advice. You said "as of right now there is only firmware for the USRP XCVR 2450 and the WARP Radio 1.4". Do you mean Soar doesn't support other daughterboads yet? for example, RFX900? 

     

    best,

    That is correct, last I knew SORA's USRP adapter, manufactured by HRHT, only had firmware for the XCVR 2450, which is loaded into the JTAG on the adapter board itself. I think Microsoft might either be working on, or have, other firmwares. Last I talked with HRHT, they suggested as much, and this was several months ago.

    If you're looking for other firmwares, contacting HRHT and Microsoft would be a good start.

    Hi Cory,

    Thanks for your clarification.

    To supplement: On the hardware side, Sora supports all the USRP radios with USRP adapter.

    Jiansong:

    Thanks for clarification. 

    Will you give some samples how to modify the firmware then? I hope it is not difficult to make such modifications.

    Do you have plan to release siuch firmwares for other USRP radios? And when?

    BTW, I prefer to RFX900 front.
