If you need help with installation of WiSense on your device, we are ready to install it for you. You just need to purchase the device and ship it to us. Please see Need Help section for more details.
WiSense is an Android based platform being developed by the WiNGS Lab at the University of Wisconsin-Madison for wireless debugging and diagnosis in both enterprise and home WLANs. The platform allows users to analyze real-time RF activity across different WiFi channels, monitor the signal quality of neighboring WLANs and detect the presence of neighboring non-WiFi activity. The ease of usage and mobility provided by handheld smartphone and tablet platforms can allow network administrators as well as users to identify location specific wireless performance issues in their WLANs. This tool is also being developed as part of our group's efforts to collect data about wireless performance at different locations and share it with the community.
So, in brief, WiSense lets you:
Please watch the small introduction video to get a feel of WiSense. Happy WiSens'ing' :D !!!
To know more about the application, see our Features section below.
Following is the breakdown of different capabilities provided by WiSense:
Using WiSense, users can visualize a real-time heat map of the RF activity across different 20 MHz WiFi channels through a waterfall display.
This tab provides a live, time-series view of the neighboring non-WiFi (e.g., Microwave Ovens) activity. This helps users identify the potential non-WiFi interference in the vinicity. Apart from the real-time activity, this tab keeps track of the recent activity as well.
Similar to the "Events" tab, users can also see information about detected non-Wifi devices in a list format. WiSense also provides other details about the detected non-WiFi devices such as their signal strengths, start and end time, operating frequency, bandwidth and duration. Apart from the real-time non-WiFi device activity, this tab keeps track of eariler detected activity as well.
This tab lists the neighboring WiFi SSIDs as well their channel frequency and signal strengths. This information can used to analyze the coverage of wireless networks at different locations as well as determine which APs may be impacted by neighboring non-WiFi activity.
The tab provides live information about the channel airtime utilization (between 0 to 100%) for WiFi channels 1, 6 and 11 at the current location. This can be used to visualize the total airtime used by neighboring WiFi and non-WiFi activity. High airtime indicates potential channel congestion and can cause poor WiFi performance
This feature allows a user to perform active throughput measurements using iperf between the device and a remote server. It can be use to determine the available throughput over the WiFi link using active measurements.
Please note that only following devices and Android versions are being currently supported for WiSense:
We're working on getting WiSense on other range of devices. So, please stay tuned!
You can now get WiSense on Google PlayStore. But, before downloading the application, please go through the Getting Started document for instructions to update your kernel.
Before downloading WiSense, please make sure that you have one of the devices mentioned in the Supported Devices section.
Please feel free to get in touch with us in case you need any help at any step. Whether it be updating the kernel, installing, downloading or using the application on your device, or anything else, we are here to help you throughout the installation process. Please find our contact information in Contact us section, and we also welcome your comments in the Comments Section.
To enable wider adoption of WiSense, we also offer to do the installation for you, thereby giving you following options:
