About this test:
Mobile carriers demote network connections to conserve battery power. But this has the potential to slow down web pages because it can take ~2 seconds to promote the network connection to full bandwidth. The demote/promote logic is described in the RRC protocal, but the specific state machine values can vary from carrier to carrier.

This test gathers information to determine how much inactivity causes network connections to be demoted. By running this test you'll be contributing (anonymously) to the growing list of results on Browserscope. By default Browserscope sorts results by browser. The state machine, however, is controlled by the radio tower, so we want to sort the results by carrier thusly. (Notice how AT&T has a ~1 second increase when the interval goes from 4 to 6 seconds.)

unverified results

I have code that applies some logic across carrier networks, whois records, and IP lookups to verify that the results match the carrier. In many cases I can't verify a test result: it's a carrier I haven't seen before, there's no info in the whois records, the IP lookup can't be found, etc. Here are the unverified results.
