Lubomir Mraz and his fellow Wislab crew members have released the documentation on their open multi-platform, multi-band wireless sensor network analyzer. Known as the Open Zigbee Sniffer, the RF device interfaces with your PC via the Ethernet interface. It includes protocol dissectors for IEEE 802.15.4, Zigbee, 6LoWPAN and Atmel LightWeight Mesh, covering the 2.4GHz and 780/868/915MHz ranges, and is designed to integrate with Wireshark. The heart of sniffer is the LM3S8962 (ARM Cortex-M3) MCU, which implements 100Mbit Ethernet controller with fully PHY and MAC layer on chip. Radio interface consists of two 802.15.4 radio transceivers AT86RF212 (sub-gigahertz band) and AT86RF231 (2.4 GHz band), and includes transmit capability.
The schematic and source code, including a project file for CooCox CoIDE, are available for download, along with complete project information at the sniffer.wislab.cz site.

So interesting. An it looks “quite” easy.Anyway waiting for open source Gerbers
Transmit capabilities…. Great!
I just realized.. I was living and studying on that university, Brno University of technology (Czeck Republic).
Really nice projects on developing !!
Thanks, final version of Open Sniffer can be found here http://www.sewio.net.
