This post shows how to connect to USRP N2x0 from a Ubuntu guest OS inside Virtualbox running on a Windows host.

In one of my research projects, I need to develop some signal processing logic that runs on the FPGA of the USRP, to meeting some delay and timing requirements. Here is a general overview of the steps to customize the DSP Rx chain of USRP N2x0 devices. Details of my particular customization will be probably discussed in separate posts.

I have been attending the Google Mobile Summit for past two days. I'll share some of the exciting projects that Google is doing as well as my personal take away from them.

Recently, I studied how Android Wi-Fi subsystem works. I was more specifically interested to learn the scan behavior. The source code related to this is mainly in framework/base/wifi/java/android/net/wifi/ within AOSP source tree.

Recently, I've been working on dynamic channel selection based on channel utilization. One problem I encountered is: how to switch both AP and devices' channel without interrupting existing TCP connection.
