Are We Getting Any Closer To The Wireless Holy Grail?

from the keep-searching dept

For years and years we've been hearing about how software-defined radio was the holy grail of wireless technologies. The idea is that the wireless radio is software-based, rather than hardware-based, and therefore can change on the fly. Thus, a single device can, in theory, do a lot more. For example, it could automatically find the best network and switch you to that network, even if it involves a totally different type of network. That's cool in theory, but it's very, very difficult and can lead to a lot of complications. There was a lot of hype about the technology a few years ago, but it's been pretty quiet for a while. That may be changing as Vanu Bose's company is starting to get some new press coverage long after his SDR company first got attention (in part, because he's the son of the founder of Bose, the speaker company). Of course, reading through the NY Times article on Vanu, it doesn't sound like we're really getting anywhere near the big vision of SDR that people talked about half a decade ago. Instead, it's still being used for very basic things. That's not to say it's not a promising, and potentially revolutionary, technology. It's just to note that we're still a very long way from it living up to its potential, even if the press is suddenly writing about it again.

    NO on SDR

    I agree with wirelessman #16,
    SDR is a buzzword, and Vanu is vaporware.
    There are 2 issues
    Digital Radio by its nature can be implemented in SW. if enough mips are there.
    DSP/FPGA/ASIC/Custom HW are all manipulating bits.
    on mobile handsets ASICS are logical choice.
    on Basestation FPGA+DSP(and even GPP(general purpose processor)
    are logical choice

    (2)RF frontends will be different, because of some fundamentals....
    Bands are different. Each require different antenna, different filters different power amplifiers etc

    Now Vanus approach is nothing revolutionary.
    Yes 20 years ago what was done with custom hw can be done in sw today.
    Big deal.
    The question remains is it worth it?

    PS Its clear that the company is in trouble.
    They raised money when it was available expanded headcount and have shrunk
