Hello All,

Here is more information about the Software Defined Radio Device:

Supports: Windows / Linux
8MHz Realtime-IQ Streaming to PC
50MHz RF Bandwidth

Available: $500 USD

via a Chicago Kickstarter coming soon


2x2 full duplex MIMO SDR System housing complete RF and DAQ subsystems on a single board. 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’s 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.

Applications developed based on USRP1 seamlessly works with this device using LibUSRP.

UHD Driver to be implemented next. :)

    WindyCitySDR created AndroidSDRv1001 which is a LiveDVD/USB image to support this SDR device without the Configuration Nightmares, and when connected to SDR hardware allows for creating "Software Defined Radio GSM Mobile Phone Networks".

    This includes Android Studio 0.1.1 Build 130.687321 Environment, as well as contains:

Asterisk 1.8

GCC 4.6.3

GNU Radio 3.4.2 + GRC

Java 1.7.0_21

OpenBTS 2.8

Ubuntu 12.04 LTS 32-bit

Pre-Configured to work with Google Voice, Just add your Google Voice Email Address & Password

You should be able to boot off the LiveDVD / USB image, and create a SDR GSM Network in under 10 minutes cleanly.

If you are within the USA , Part 15 of the FCC Rules & Regs allows for utilizing SDR devices as Test Equipment.

Ettus Research, PerVices, & other Software Defined Radio providers sell their products under the following (Generally Speaking):

Licensing

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

Mreidiv,

This is EXACTLY what I am hoping to do is lower the pricing so that new designs can be released.

This device replaces the Ettus Reasearch USRP1 and all applications that works with the USRP1 will work with this device too.

I also include a .iso file that will allow for creating your own GSM mobile phone networks in under 10 minutes.

Hello All,

This device should be available May 2014.

I'm going over the components again tonight, ordering components tomorrow, to send to the Assembler for final completion.

I've had this ASRP1/SDR MIMO working with OpenBTS for between 2 - 3 months without issue.

http://www.WindyCitySDR.com has more information as to where it was successfully demonstrated.

http://www.SoftwareRadio.us shall be where the SDR MIMO shall be sold from.

Sincerely,

Just to make sure I understand, with this one could set up a private GSM phone network?

You'd just need a number of unlocked GSM phones?

very cool, good luck!

FTB,

Here in the USA, you can create whatever type of network you want as long as it is under 1W, or between 67 - 200 feet.

So for instance, if you wanted to create your own GSM network, and the current LIVE network uses 1900 Mhz, you'd utilize a entirely different RF band say 900Mhz.

If you wanted to transmit on a "Licensed Frequency" you could apply with the FCC for what is called a STA, or Special Temporary Authority. Or you could get permission from your "licensed carier" to provide you with the necessary permission to transmit.

Beyond all of that, just last night I tested this handheld wideband SDR against the Rangenetworks 5150, and the 5150 didn't work which a University paid $2000 for, and never gotten it to work a SINGLE time!

This device can allow for whomever to create Radio Communications systems without the traditional expensive hardware costs. This is a real revolution indeed :)

I researched the question of wether or not you need to get (=pay for) a license to broadcast on the GSM band. I found this law:

http://wetten.overheid.nl/BWBR0023553 (dutch, obviously)

It was drawn up in 2008 and with regards to running your own GSM Picocell it is completely legal so long as you restrict your transmitting power to 250mW as well as the frequency ranges specified. The exact frequency bands are listed in "bijlage 1" (translated: attachment 1). It's obviously wise to steer clear of the frequencies used by the commercial parties since they have more transmitting power and stand a good chance of drowning out your own signal, but still, that's pretty cool.

So the question for me now becomes, how to I use your SDR to become a GSM Picocell and most importantly, how do I hook it up to a local PBX (asterisk or whatever). I would *LOVE* to run my own local GSM network and make it a gateway onto some VOIP gateway of choice.

Hi Joel/KD6W,

I cancelled the Kickstarter before it failed allowing me the opportunity to bring it back.

Ordering the final components as we speak. for the MIMO, but in the interim, everyone should check this out:

http:www.SoftwareRadio.us

I'll report back shortly and yes this is still in motion.

Very cool and thanks for the update. I'm very interested to see what you come up with once boards come up to production. I'm very dubious about sponsoring any more kickstarters as I have already funded a few duds. Sorry, not you but I'm twice bitten. 73 -KD6W

KD6W,

I'm going to be soldering the boards by hand for the time being as it is BEYOND expensive to have them assembled at this point in time. This is whats taking some time as we speak, but I hope to be ready soon.

I know what you mean. I like doing my own too. I have a Bausch & Lomb stereo scope with different objective strengths and variable zoom for doing all the fine hand placement cuz I can't see the tiny stuff ever since I got my eyes blasted. I'm building a hot melt flow oven from a black and decker toaster oven for soldering BGA parts.

Hello All,

I went to this event last week:

Chicago Council on Science and Technology is pleased to co-present:

The Birth and Death of the Cell Phone

30bits-cooper-tmagArticle.jpg

Martin Cooper changed the world when he made the first cell phone call 40 years ago, on a two-pound-plus Motorola DynaTAC phone. His first call: to the head of research at Bell Labs, a company that also was attempting to build the first cell phone. It would be over a decade before the first cell phone would be commercially available, but Cooper's call opened the door to true mobility and continues to affect virtually every aspect of our lives.

http://www.c2st.org/event/2014/11/birth-and-death-cell-phone

And I asked Mr. Cooper's viewpoints on Software Defined Radio & Cognitive Radios.

Here his video response yourselves:

SDR4All Toolbox is a package that intends to help you transform an


Universal Software Radio Peripheral, or other SDR Devices,


into a plug and play device.


HandHeldSDR.gif It includes a device driver, a component that enables the


communication and a server interface and we’ve contacted the


Authors to prospectively utilize the source code to expand its


capabilities!


https://hal.archives-ouvertes.fr/docs/00/44/69/67/PDF/C0947.pdf



Yes this recognizes the HandHeldSDR, and I have been in contact with the authors


to try and obtain the Source Code to EXPAND its capabilities.

Hello All,

As the "Title" of this SDR thread/Post is no longer valid, I've posted the successful results of us now manufacturing the SDR device, in the Chicago area, that was recently demonstrated before TadHack 2015 held at the Illinois Institute of Technology:

You're... not making a wideband SDR anymore?
