Web applications might be interested to know if the connection is more around a few dozen of kb/s, a few hundreds of kb/s or a few Mb/s. If the connection is 120 kb/s or 110 kb/s is unlikely important. The UA can easily guess an average bandwidth based on network type for mobile connections. > Whether you raise the event or not, you need to test the bandwidth frequently enough, and then you determine if the change is significant enough or not. I'm not sure how you can avoid this frequent bandwidth test, and it will generate a lot of traffic and drain the battery. That's a good point. This said, implementations can do only one bandwidth check per connection type change or very rarely. I would tend to say it is mostly an implementation issue but I would be glad to hear viable spec alternatives to fix that. > Also, don't you need the underlying native implementations to support this functionality as well? That is not the case currently, for example Android just exposes the type and subtype of connection. What do you mean? -- Mounir
