I'm up as -- -- for CNET here with -- stone of real metrics. Now they partner with CNET to provide the coverage maps that you see for mobile phones on cnet.com. And I'm gonna see just how they independently test. The signal strength and the data connections for all the cellphone carriers an area. So Josh this is a pretty big -- here and see that you got a bunch of phones and battery pack strapped to -- it what are you looking at. -- -- starts with off the shelf consumer phones there's a phone for each of the major carriers we're testing in the market. And all of them are connected to this master device its actually controlling. And automating calls and each of these phones is running our proprietary software and collecting. Samples around signal. Data and texting what we typically do is -- we run and a proprietary software this randomly selects weak points along a route. For the drivers and they're able to plan their routes and select three indoor locations at each way point. That are publicly available like a supermarket at a gas station kind of thing. Sir -- I see that these phones most of them look like they're calling a phone number of -- doing exactly. These these are actually calling it. A the server and holding an actual -- and testing the signal strength back to that server at the same time so they're gonna upload my photos videos he yeah exactly so every five minutes and we won't run through signal strength and data upload and download speeds and text performance. Today carriers actually user data to go ahead and find out where -- weak spots are so that they can improve their networked -- can and do use that reporting to improve technology throughout the market street think you some -- -- really fun thank you -- just -- -- -- for CNET you can catch all of our content at cnet.com.
