A software radio is a wireless communications device that performs all
of its signal processing in portable, application level software. By
simply running a different program, a software radio can become a cell
phone, wireless LAN, cordless phones, garage door opener or
walkie-talkie. The flexibility enabled by software radio allows for
faster technology tracking, since standards upgrade are simple software
downloads. Software radio is a multi-disciplinary systems effort,
bringing together research in digital signal processing, communications,
operating systems, software engineering and algorithms.
WindyCitySDR MIMO is a daughtercardless 2x2
full duplex SDR transceiver complete with RF and DAQ subsystems on a
In radio, Multiple-Input and Multiple-Output, or MIMO
(commonly pronounced my-moh or me-moh), is the use of multiple antennas
at both the transmitter and receiver to improve communication
performance. It is one of several forms of smart antenna technology.
Its architecture is designed for a true MIMO System. It
meets the unique architecture required for MIMO systems which are not
part of traditional MIMO hardware using common clock for RF subsystems
where a continuous RF phase tracking is required. Coupled with these
benefits, it hosts onboard RF transceiver subsystems capable of tuning
frequencies from 400MHz to 4.4GHz. & will be distributed / manufactured out of Chicago,
Supports: Windows / Linux 8MHz Realtime-IQ Streaming to PC 50MHz RF Bandwidth
WindyCitySDR received this device in October of 2012 and in November
2012 swapped the 64Mhz Clock for a 52Mhz Clock and has been
demonstrating it successfully at different Chicago Tech events ever since.

AndroidSDRv1001 is a LiveDVD/USB image to support this SDR device without configuration nightmares and when connected to appropriate SDR hardware, allows for
the creation of "Software Defined Radio GSM Mobile Phone Networks", for example.
This includes Android Studio 0.1.1 Build 130.687321 Environment, as well as contains:
You should be able to boot off the LiveDVD / USB image and create an SDR GSM Network in under 10 minutes cleanly.
***UHD Driver needs to be implemented to get the GNU Radio versions 3.4.2 through 3.7 applications to function****
If you are within the USA , Part 15 of the FCC Rules & Regulations allows for utilizing SDR devices as Test Equipment. Ettus Research, PerVices, & other Software Defined Radio
providers sell their products under the following (Generally Speaking):
"The USRP is sold as test equipment. If
you choose to use your USRP and daughterboards to transmit using an
antenna, it is your responsibility to make sure that you are in
compliance with all laws for the country, frequency, and power levels in
which the device is used. Additionally, some countries regulate
reception in certain frequency bands. Again, it is the responsibility of
the user to maintain compliance with all local laws and regulations.http://www.ettus.com/legal/licensing "
Chicago started both the United States and then the world's Mobile Phone Industry in the early 1980's from Soldiers Field:
"It was 25 years ago today, October 13, 1983, that the very first
commercial cell phone call was made. Bob Barnett, president of Ameritech
Mobile communications, called Alexander Graham Bell's nephew from
Chicago's Soldier Field using a Motorola DynaTAC handset, referred to as
the "Brick" because of its hefty size."
In Chicago's past, everyone was employed at Motorola, and everyone either had, or wanted badly, a Motorola Mobile Phone. Yet today, not a single Mobile Phone is manufactured within the USA, though that's about to change:
Motorola to make new smartphone in Fort Worth, add 2,000 jobs
But Fort Worth, Texas isn't Chicago, Illinois so Chicago won't see those employment gains as a result of Motorola moving back its manufacturing to the USA.
And like Motorola, other Hardware Radio manufacturers aren't producing devices that enables the user the ability to access a wide range of Radio Frequencies that can be processed directly from a General Purpose Processor, Intel / AMD, Computer.
We as human beings utilizes under 0% of the known Electromagnetic Spectrum that exists in the Universe and as such, why pay the most amount of money to interact with it?:
Today in the Chicagoland area, there isn't "Advanced Manufacturing" as represented by Chicago's past:
"In 1980, Christine J. Walley’s world was turned upside down when the
steel mill in Southeast Chicago where her father worked abruptly closed.
In the ensuing years, ninety thousand other area residents would also
lose their jobs in the mills—just one example of the vast scale of
deindustrialization occurring across the United States."
During WGNTV's interview with Christine J. Walley she states,
" when these industries leave a community, it becomes a limited class community capped by unemployment "
WindyCitySDR intends on distributing & manufacturing Wideband Software Defined Radio Transceiver(s), in the Chicagoland area, that does a majority of the Radio Frequencies of Motorola Mobility, Motorola Solutions, Motorola Ventures Portfolio Companies, + Google's recently filed Special Temporary Authority with the FCC regarding Radio Frequencies 2500Mhz - 2600Mhz, all in a single device:
Every different color you see in the verticle scrolling graph becomes an opportunity for employment, computer programmers / DSP programmers, to create those "waveforms" in software to be run on, for example, a laptop computer as pictured below:
Because Software Defined Radio can become the "NEW Physical Layer in Wireless Communications", it offers us Multi-Purpose Wideband Software Defined Radios for
Public Safety, Wireless Infrastructure - MVNO, MNO, Set-Top-Box,
Airport Control Towers, Subway Communications Systems, City, County /
State Police / Public Safety, Real Estate Concerns, etc., Software Defined Networking goes right along with Software Defined Radio as you can see from this picture:
I am interested in getting this SDR device to work with the following Android & Apple "Smart Device" Applications:
Charles Scharlau's iSDR Application which turns a Apple "Smart Device" into a Software Defined Radio receiver:
Martin Marinov's SDR Touch Android Application sdr.martinmarinov.info/:
WindyCitySDR is interested in implementing OpenLTE with this device to allow for creation of inexpensive LTE 4G networks:
Including implementing TV White Space Applications:
On January 16, 2013 before the Chicago Association of Computing Machinery, Vice Chairman Andrew Klein, stated, " Martin, these Software Defined Radio devices you've demonstrated/exhibited is Technology we don't manufacture here in Illinois ".
WindyCitySDR intends on working with the Illinois Manufacturing Education Foundation, "Last Mile Broadband Initiative" Entities, Real Estate Entities, & other Chicago Technology Groups to train & create a Chicago based Software Defined Radio Community which doesn't really exist today.
Through manufacturing this device locally brings " Advanced Technologies " back to Chicago which can have a tremendous economic/cultural/social impact!
A listing of where this device has been demonstrated:
****AD9862BSTZ 12-/14-Bit Mixed Signal Front-End (MxFE®) Processor for Broadband Communications is on BACKORDER until October 2013****
So Please RESERVE your SDR device TODAY to ensure receipt of this device!!!!
All major components of the SDR device are manufactured within the USA.
Risks and Challenges
Due to the nature of test equipment, we are in contact with the FCC to ensure that we are in compliance with American and international regulatory bodies.
As with any other hardware project, our delivery dates can be adversely affected by component inventory. To avoid such surprises during a mass production run, only parts with healthy stock estimates were selected during the design phase. Additionally, we have approached and remain in contact with many component distributors about their inventory.
A successful mass production run has been carefully planned since the very beginning of the project. We selected a PCB manufacturer in the Chicagoland area that has experience with prototype and mass production runs for boards that are similar to ours. By using the same manufacturer all the way through, we will be able to correct and avoid issues that would affect mass production runs early on.
As of now our delivery dates are based on worst case scenario lead times with additional headroom for error for all our parts.
