I don't think that this will "shake up" the amateur world, but it certainly looks like a very worthwhile contribution and it does appear to have a number of uses besides just communication. So I will be quite interested to see what all develops. If it can indeed be made to function as the core of a spectrum analyser then it would have immediate value to quite a few people, both hams and experimentors. BUT please don't compare them to Ardunio. Those ardunio projects always substitute a microcontroller board for a function that could be done with a simple comparator. A shameless promotion of a product line at the expense of understanding actual circuitry.
"Myriad-RF boards use FPRF transceivers to support all the mobile broadband standards – LTE, HSPA+, CDMA, 2G..."
Does this mean that the board can send and receive according, to, e.g. the CDMA PHY standard? Or does it mean that the board can send and receive at the relevant rf frequencies and actually imposing the digital signal on top of that is up to you?
It is interesting to note that the BladeRF is based on the LMS6002D IC from Lime Microsystems because as Nuand states: "this transceiver is capable of handling anything from simple FM audio to the latest 4G LTE standard."
BladeRF does include the FPGA and a USB 3.0 digital connection and bus power.
Take a look at the BladeRF from Nuand:
They have an open source radio platform which uses GNU Radio and provides analysis. I have been rather rash and ordered one already!
